By Cian Fitzpatrick | 17th May 2024 Not the cool kid in town, and as old as the internet itself, email remains the most productive business tool. By the same token, it’s the most effective tool for cybercriminals. With this in mind, regulators have been focusing on email security in an attempt to curtail cybercrime. As methods became more sophisticated than simply poorly worded emails promising royal riches from secret vaults in places unknown, so too have security protocols and technology to halt the incoming onslaught. Proactive security solutions are the only way to protect organisations in this age where data is gold. DMARC is now a compliance issue Domain-based Message Authentication, Reporting, and Conformance, also known as DMARC, is a solution developed to be highly effective in email security. So much so that Google and Yahoo have implemented stringent DMARC regulations taking effect in February of this year for senders of 5000 or more messages per day. Email domains must have a DMARC policy in the DNS (Domain Name System) and messages must pass DMARC alignment, or they won’t be delivered to Yahoo and Gmail inboxes. This applies to messages sent on an organisation’s behalf through email service providers such as MailChimp. The DNS is the equivalent of the internet’s phonebook – remember those? We access websites through a name, but web browsers talk to each other through IP addresses, so the DNS essentially converts domain names to IP addresses. What’s DMARC? DMARC integrates SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify an email’s authenticity. One of the biggest issues in recent security breaches has been that attackers can impersonate a domain, making an email look like it comes from someone, when it really comes from someone else (a fraudster). DMARC is a robust solution that makes sure to check that the email originates where it says it originates, and can then block phishing and impersonation attempts. DMARC relies on two key elements: SPF confirms the origin of an incoming email. And DKIM, which uses encryption to authenticate an email and prevent identity forgery. DMARC records instruct recipient servers on handling emails that fail authentication checks, either by quarantine or outright rejection. This may be flagged due to a difference between a supposed email sender and the actual email address. It’s a crucial layer of defence. In the old days, platforms like Google relied on filters to sieve out spammers and fraudsters. The filters were often so severe that legitimate emails would be blocked. Cyber security is always a fine line between keeping a system safe and minimising user discomfort. Get DMARC Compliant with Topsec today Get A Quote More than just compliance, it’s about trust. Google and Yahoo’s move to compel businesses to adopt DMARC is encouraging. On one hand, organisations are teaching their employees to have a healthy distrust of email. However, as a brand and organisation, you want those with whom you engage to trust your digital communications. By implementing solid security measures like those offered by Topsec Cloud Solutions, it’s an opportunity to strategically raise your brand profile as one that can be trusted. The DMARC initiative by Google and Yahoo isn’t purely about technology. The three pillars behind this strategy from a user’s perspective are that email will be authenticated in the background (as discussed above), it will be easy to unsubscribe from mailing lists, and emails cannot be spammy – they have to be wanted by recipients. This is a positive move for users and organisations, although it does mean that businesses may have to review their technology strategy if they send more than 5000 emails a day. The idea is to encourage and enhance trust in email communications and to proactively protect against fraud. For organisations that have yet to implement DMARC, it’s an opportunity to ensure the protocol is correctly executed, but it’s also as a confidence-building practice within and across organisations. There’s an element of brand reputation and integrity in all of this. Who doesn’t want to do business with an ethical organisation that looks after its assets and its clients’ assets? For marketing teams, it’s a chance to demonstrate outstanding values and a security-aware ethos. This is not just a technology issue. Once again, it’s highlighted that cybersecurity belongs to each stakeholder in the business. There’s also the compliance angle. Failure to comply will lead to delays in email delivery and possible rejection. The effect on brand reputation and trust in integrity will be significant. And that’s the best-case scenario. The possibility of a cyber attack becomes very real for organisations that don’t comply, or which implement DMARC incorrectly. These attacks have devastating financial and reputational consequences. It’s the responsibility of each organisation to secure their digital channels. Recovering from a phishing or spoofing attack is expensive, time-consuming, and incredibly stressful for stakeholders. Data and privacy breaches become a nightmare for everyone and the damage can be permanent, or at best, lengthy to repair. DMARC in practice. Both Google and Yahoo offer transparent error codes for each email rejection. The error codes are freely available and offer an explanation along with the numerical code, making it easy to understand why an email was blocked, and what action should be taken. Failures are generally either temporary or permanent. With 90% of all cyber attacks initiated through phishing, which is generally done via email, it’s understandable that the largest tech organisations are taking control. By forcing companies to protect themselves and their users, they’re helping to make the internet a safer place and combat cybercrime. This is and always will be a process, but organisations need to work together. And this is more than a security issue, it’s a chance to prove to clients that your organisation is taking security seriously. Our DMARC Protection
How to Build a Resilient Email Security Architecture
How to Build a Resilient Email Architecture. Strategies for Enhanced Cybersecurity Get a Quote Download Datasheet Email Security > How to Build a Resilient Email Architecture. By Cian Fitzpatrick | 1st May 2024 Email (and email security) is the cornerstone of modern business. Efficient, convenient, productive, it’s the most prolific business tool on which we’ve come to rely. Hence, email remains the primary medium by which cyber threats enter an organisation (91% of threats come through this gateway). Tactics to slide through security systems are becoming increasingly sophisticated, and reliance on human fallibility is key to successful breaches. Effective cybercriminals use a multipronged approach in their endeavours: technology… and social engineering. If we wish to counteract their techniques, we need to proactively defend our assets. And also use a multidimensional strategy. Technology alone is not enough. But it helps. Employee education alone is not enough. But it helps. What are the biggest threats to email security? Bad actors are getting smarter. We’re seeing more malicious QR codes within emails and email attachments. They often appear harmless at first, but post-delivery, they’re able to change destination or characteristic. Likewise with URLs, threats can be triggered and clicks redirected, hours or even days after arrival in an inbox. This can make it difficult for gateway security systems to nab threats as they enter a domain. There’s also been a rise in OneDrive as a delivery method of malicious threats, with files that look initially like they contain nothing untoward. Again, threats are triggered some time later. Whaling and spear phishing attacks are on the increase, where senior staff is tracked and targeted. Information is accumulated from across the web, using social media, and professional platforms to find out who’s-who and where they are. Impersonation techniques involve the clever use of AI and other easily available technology. Remember that this is an industry the size of a country’s economy (third after the US and China, in fact). Compromises in the supply chain are also growing. The use of contractors can be risky. But who doesn’t use contractors and partners? If a supplier’s security is not up to scratch, the knock-on can be huge, and cybercriminals are exploiting smaller suppliers to funnel into larger organisations. Partners are often trusted and the relationship is solid, and so systems don’t flag them up. Human behaviour will always be a stumbling block for organisations. And not just users who are prone to social engineering – which is all of us – there’s also the risk that protocols like DKIM/DMARC are not set up correctly. Compliance regulations and cyber insurance policies may demand these protocols, but correct set-up takes effort and understanding. IT departments are under huge pressure, it’s not surprising then that these protocols become a mere box-ticking exercise. IT staff are often at the point of burn-out and their familiarity with risks, or incessant flags on the systems they monitor, can hinder them from seeing the wood for the trees. What can we do? Central to protecting a cyber environment is a proactive approach. Constant staff-awareness training should be one arm of defence, and technology, the other. A proactive approach means tackling emails before they reach inboxes, before they’re in transit on an organisation’s infrastructure. Once a threat is in an inbox, it could be too late. The onus is then on the user to determine that the email is fraudulent, and this could be the weak link. The sophistication of these scams lies in their appearing sound of character, links and attachments are unthreatening. But they’re manipulable once they’ve reached their destination, and that when they attack. Scammers are taking less of a birdshot approach now. They’re targeting specific people or roles in an organisation, and starting a process of engagement which begins innocently enough. Like this, their emails seem legitimate and go unflagged. Once they have you on a trusting journey, they’re able to lead you to malicious content. DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol. Its aim is to protect an email domain from unauthorised use, particularly email spoofing, or the creation of forged email addresses. Set up DMARC Protection correctly in order to protect businesses from email-based compromises, phishing scams, and other cyber threat activities. Ensure your email security solution scans malicious qr codes Get A Quote The path of an email in an ideal environment On entry to an organisation, an email encounters an antivirus scanner, where it will be reviewed for legitimacy. DMARC and DKIM protocols will be correctly configured and vulnerabilities are constantly monitored on the Dark Web. The AV scanner will look at whether an email’s credentials have been previously encountered, if there’s an existing fingerprint for it, whether or not it has an attachment, link, or QR code. There are three options at this point. The email may be found to be legitimate and risk-free, it may be deemed malicious and blocked, or it may go into a sandbox for further investigation. There are several sandbox environments, one for attachments, one for URLs, one for QR codes. What’s a sandbox? An email sandbox is an isolated environment identical to the user environment. It’s like a laboratory, where an attachment can be exploded or code can be executed in the vacuum of the sandbox without affecting or bringing down the entire network. Sandboxes are particularly effective against Advanced Persistent Threats (APTs), which are custom-developed, targeted attacks. Their aim is to steal data and they’re designed to elude traditional detection methods. Human intervention and observation allows for further research into an attempted attack and action taken. The knowledge and experience of people cannot be underestimated in cybersecurity. Architecture aside… You can have all the best systems in place, solid procedures, cutting edge technology, and the most vigilant IT team, but ultimately, the target for cybercriminals is you and me. Every person in an organisation is a possible access point for a scammer. And so it is up to each person to be the

Ransomware and Email Security: A Comprehensive Guide to Protecting Your Digital Assets
Ransomware andEmail Security A Comprehensive Guide to Protecting Your Digital Assets Get a Quote Download Datasheet Email Security >Ransomware Ransomware and Email Security: A Comprehensive Guide to Protecting Your Digital Assets By Cian Fitzpatrick | 14th February 2024 Ransomware attacks have escalated rapidly in the first few months of 2024. And while they were always a formidable threat to individuals and businesses alike, these attacks are becoming even more sophisticated. But all is not lost. As Deloitte’s report explains, 91% of all cyber attacks come through email. That gives us the first clue as to how to withstand being In the crosshairs of ransomware attacks. Namely, email security emerges as a frontline defence, pivotal in thwarting the advance of malicious actors. To do this, it’s important to understand the intricacies of ransomware and how fortifying your email protocols can significantly mitigate the risk of a devastating breach. In this article, you will learn: The nature and evolution of ransomware threats. Best practices for enhancing email security. How to create a robust response plan for ransomware attacks. Investing in your email security is a strategic business move that has benefits across your whole organisation. Now that it’s Spring, why not spring clean your inbox to protect your digital assets against the growing tide of ransomware threats through strategic email security measures. Understanding Ransomware DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. This protocol, integrating SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), is crucial in verifying email authenticity. In turn, ensuring an email really is from who it says it is from reduces the risk of cyber threats such as phishing and spoofing. Now we can see the Valentine’s link! Verifying your email authenticity is how you treat your email recipients well! The Critical Role of Email in Ransomware Attacks Email remains the most common vector for ransomware attacks, serving as a direct line for attackers to deliver malicious payloads to unsuspecting victims. This is a sobering thought, but it’s also an encouraging one. Shore up your email security and you go a long way to securing your whole business. The simplicity and effectiveness of email-based tactics, combined with the human factor of curiosity or negligence, make email a preferred tool for cybercriminals. Ransomware is often spread through phishing emails that masquerade as legitimate communications from trusted entities. These emails might contain malicious attachments or links that, once clicked, initiate the ransomware infection process. For example, a seemingly benign PDF or Word document attached to an email can, when opened, unleash ransomware onto the user’s system. Similarly, links embedded within the email body can redirect users to compromised websites designed to download ransomware directly onto their devices. Protect your organisation against ransomware attacks Get A Quote Enhancing Email Security to Combat Ransomware Even with robust preventive measures in place, the possibility of a ransomware attack cannot be entirely eliminated. For this reason, having a comprehensive ransomware response plan is crucial for minimising damage and swiftly restoring operations. Key components of an effective response plan include immediate isolation of infected systems, identification of the ransomware variant, a communication strategy, engagement with cybersecurity professionals, recovery and data restoration and post-incident analysis and strengthening defences. Developing a Ransomware Response Plan Google and Yahoo will start rejecting a portion of email correspondence from users who don’t comply fully by the deadline in the coming months. You may receive particular error codes and messages if your emails are refused because they don’t follow these new guidelines. These codes are useful bits of information that can help you solve the problems; they are not just arbitrary strings of characters and numbers. Case Studies: Successful Defense Against Ransomware These case studies have been compiled from an amalgamation of real world examples to highlight the importance of preparedness, the efficacy of comprehensive email security and the benefits of having a rapid response plan. 1. Example of a Phishing Email Leading to Ransomware Infection. Imagine a finance manager at a mid-sized company receives an email that appears to be from their CEO, requesting urgent review of an attached invoice. The email looks legitimate, complete with the CEO’s email signature and company logo. However, the attachment is actually a malicious file that, once opened, encrypts the company’s financial data and demands a ransom. This example illustrates the sophistication of phishing attempts and the importance of verifying email contents before opening attachments. 2. Example of a ransomware attack on a small business without a backup plan. A small retail business falls victim to a ransomware attack after an employee clicks on a malicious link in an email. The ransomware encrypts their sales and inventory data, causing the business to halt operations. Without recent backups, the business faces a dilemma: pay a hefty ransom with no guarantee of data recovery or attempt to rebuild its data from scratch, risking significant financial and reputational damage. This scenario highlights the critical need for regular data backups as part of a comprehensive cybersecurity strategy. 3. Successful Mitigation of a Ransomware Attack Through Quick Response. An IT administrator at a law firm notices unusual network activity and quickly identifies it as a ransomware attack in progress. By immediately isolating the infected systems and deploying the firm’s response plan, the administrator prevents the ransomware from spreading to critical case files. Thanks to well-maintained and encrypted off-site backups, the firm is able to restore the affected systems without paying the ransom, showcasing the effectiveness of a rapid response and robust backup strategy. The Ransomware Menace The menace of ransomware looms large. It’s also not going away anytime soon (if ever). But understanding its workings and prioritising email security can significantly reduce your vulnerability to attacks. Our intention with this article has been to explore the evolution of ransomware, the critical role of email in its dissemination, and actionable strategies for fortifying your defences against these cyber threats. Additionally, the development of a comprehensive ransomware response plan cannot be over exaggerated, nor the lessons learned from successful
Enhancing Email Security with DMARC: A Must for Businesses in 2024
Navigating the New DMARC Landscape Google & Yahoo’s 2024 Regulations & Error Codes Get a Quote Download Datasheet Email Security >DMARC Navigating the New DMARC Landscape: Google & Yahoo’s 2024 Regulations It can seem strange to link Valentine’s Day with DMARC rules, but the month of love has something to tell us about how we treat our email recipients. And the two largest email platform providers in the world are driving this point home. As of February 2024, Google and Yahoo have implemented stringent DMARC (Domain-based Message Authentication, Reporting, and Conformance) regulations, significantly impacting how businesses handle email security. For years, Topsec Cloud Solutions has been at the forefront of guiding companies through all of their email security needs. We’re here to do the same with the latest rules. Follow the advice in this blog to ensure your firm is fully compliant with the DMARC requirements. By Cian Fitzpatrick | 14th February 2024 Understanding DMARC and Its Importance in Email Security What is DMARC? DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. This protocol, integrating SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), is crucial in verifying email authenticity. In turn, ensuring an email really is from who it says it is from reduces the risk of cyber threats such as phishing and spoofing. Now we can see the Valentine’s link! Verifying your email authenticity is how you treat your email recipients well! The Mechanics of DMARC: SPF and DKIM The DMARC protocol hinges on two foundational elements: SPF, which confirms the origin of incoming emails. And DKIM, employing asymmetric encryption to authenticate emails and prevent identity forgery. The Impact of Google and Yahoo’s DMARC Rules on Businesses Adapting to the New Standards The recent mandate from Google and Yahoo necessitates businesses sending over 5,000 emails daily to adopt DMARC technology. This move is aimed at reinforcing trust in digital communications and safeguarding against electronic fraud. Therefore it’s safe to say that adopting DMARC rules in your own organisation is not only a compliance issue. It’s a strategic move towards strengthening your email integrity, fortifying your cyber threat defences and ultimately taking care of your brand’s reputation. In this era, where email communication forms the backbone of corporate communication, ensuring that emails are verified and trusted has never been more critical. Your emails are the vital conduit between you and your customers. For this reason, businesses must understand that DMARC implementation is more than a technical requirement. It’s a commitment to upholding the highest standards in digital communication. By aligning with these new standards, businesses can demonstrate their dedication to cybersecurity. This goes a long way to enhancing your reputation and building stronger relationships with clients who value security and reliability. Moreover, with the proliferation of sophisticated phishing attacks and email scams, DMARC acts as a frontline defence, ensuring that the emails businesses send and receive are legitimate and safe. Start your free dmarc trial today Start Trial The Consequences of Non-Compliance Failing to align with these standards could lead to significant communication barriers, as emails may be rejected by these platforms. This change underscores the importance of adopting DMARC not just for compliance but for enhancing digital security and maintaining corporate integrity. If your organisation doesn’t comply with these rules, email rejection will be just one of the consequences you face. You’ll also need to account for diminished brand reputation. It’s not difficult to see how customers and partners would lose trust in an organisation’s ability to secure its communication channels. In the worst-case scenario, businesses may find themselves vulnerable to cyber-attacks, including phishing and spoofing. The devastating consequences of these attacks, ranging from data breaches to financial losses, are frequently reported in the media. Moreover, non-compliance could also translate into legal challenges, especially for businesses in industries regulated for data protection and privacy. Therefore, it is imperative for organisations to understand that adhering to these new email security standards is not an option but a necessity. The proactive adoption of DMARC can serve as a badge of honour, showcasing a company’s commitment to security and modern best practices in digital communication. So there’s a marketing and business development win here too. Recognising Various Google & Yahoo Error codes Google and Yahoo will start rejecting a portion of email correspondence from users who don’t comply fully by the deadline in the coming months. You may receive particular error codes and messages if your emails are refused because they don’t follow these new guidelines. These codes are useful bits of information that can help you solve the problems; they are not just arbitrary strings of characters and numbers. Google Error Codes Google offers transparent explanations for each email rejection. These are a few of the error codes that you can see if you don’t follow Google’s guidelines for senders. 550, “5.7.26” Unauthenticated email from domain-name is not accepted due to domain’s DMARC policy.

Navigating Email Security Challenges: Trends of 2023 Show The Way Forward for 2024
Email Security 2024:Overcoming Challenges faced in 2023 Here are the top Email Security trends that we think will shape 2024. Get a Quote Download Datasheet Email Security > Navigating Email Security Challenges: Trends of 2023 Pave The Way Forward for 2024 As we progressed through 2023, the digital landscape witnessed a continuous evolution in email security threats. In 2024, these challenges are not just growing in number, but also in sophistication, making it imperative for businesses to adopt robust security measures. In this detailed exploration, we will uncover the trends that have defined email security in 2023 and share the comprehensive solutions that Topsec Cloud Solutions offers to counter these threats effectively in the next 12 months. By Cian Fitzpatrick | 18th January 2024 Topsec’s Key Email Security Trends Observed for 2023 Post-Delivery URL Threats The year marked a significant rise in URLs that initially appear safe but later transform into gateways to malicious websites. This sophisticated tactic evades conventional security measures, as the harmful nature of the URLs activates only after they have bypassed initial security screenings. This trend underscores the need for more dynamic, real-time security solutions capable of responding to threats as they evolve. In response to this challenge, Topsec’s URL Scanner offers a robust solution by providing real-time scanning of URLs. It effectively identifies and neutralizes threats even after the URLs have been initially cleared, ensuring continuous protection against these evolving cyber threats. Malicious File Shares Increasingly, attackers are embedding malicious content in shared files. These files often appear benign and pass through security checks unnoticed. Once opened, they can unleash malware or lead to data breaches. This trend highlights the need for more advanced file scanning technologies that can detect hidden threats within shared documents. OneDrive as a Delivery Method The trust placed in OneDrive, due to its integration with Windows, has been exploited by cybercriminals. They use it as a conduit for delivering malware, relying on the inherent trust users have in the platform. This method’s rise in popularity calls for more nuanced security measures that can differentiate between legitimate and malicious OneDrive links. In response to this growing threat, Topsec’s Office 365 Email Security Solutions offer robust protection mechanisms specifically designed to intercept and neutralize such threats before they reach users. By employing advanced scanning technologies, Topsec ensures that only safe, verified content is allowed through, enhancing the security of your digital communications within Office 365. Malicious QR Codes The use of QR codes in emails and attachments as a means to redirect users to harmful websites post-delivery has become more frequent. Known as quishing, these QR codes often change their destination URLs after passing initial security checks, making them a formidable threat to track and neutralise. Impersonation Scams The sophistication of impersonation scams has grown, with attackers expertly mimicking legitimate entities to deceive users. This trend has been exacerbated by the increased use of digital communication, making it harder to distinguish between genuine and fraudulent interactions. Lack of Proper Setup (SPF, DKIM, DMARC) A notable number of organisations still fall short in setting up proper email authentication protocols like SPF, DKIM and DMARC. This oversight leaves them vulnerable to spoofing and phishing attacks. Proper implementation of these protocols is essential for authenticating email sources and maintaining email integrity. Stay a step ahead of malicious actors Get Quote Phishing Awareness Deficit Despite heightened awareness, phishing remains a prevalent threat, with many users still falling victim to these scams. This trend highlights the ongoing need for comprehensive phishing awareness programs that educate users about the subtleties of these attacks and how to avoid them. Multiple Admin Access Issues The practice of multiple administrators having access to a single account has introduced significant security risks. This approach can lead to confusion, oversight, and increased vulnerability to coordinated attacks targeting admin credentials. Supply Chain Compromises Supply chain issues, exacerbated by global economic and geopolitical factors, have led to increased vulnerabilities in email security. These compromises affect organisations at multiple levels and require a more integrated approach to security that considers the entire supply chain. Challenges of Hybrid/Remote Work The shift towards hybrid and remote work models has introduced new challenges in email security. Remote work environments often lack the robust security infrastructure of office settings, making them more susceptible to email-based attacks. Burnout in Cybersecurity The increasing complexity and volume of threats have led to burnout among cybersecurity professionals. This human factor can significantly impact an organisation’s ability to effectively manage and respond to security threats. Direct Forwarding Risks The convenience of direct forwarding features in email systems has been exploited by attackers, leading to security breaches. Attackers manipulate these features to reroute sensitive information, often without the original sender’s knowledge. This trend calls for a more comprehensive monitoring of email flow within organisations to detect and prevent unauthorised forwarding. How Topsec Cloud Solutions Can Help?

As reported by HubSpot, an astonishing four billion individuals engage in daily email usage, making it a prime target for cybercriminals. But the good news is there are plenty of practical ways to shield your precious data from potential data risk. Understanding and preempting these risks ensures your peace of mind, and the peace of mind of your customers, with the assurance that your email exchanges are well-protected. By Cian Fitzpatrick | 21st December 2023 Why Email Security Matters Confidentiality Emails are often repositories of sensitive data – personal details, financial information and/or even strategic business plans. The lack of robust security measures can lead to dire consequences if this data falls into the wrong hands. Prioritising email security is key to maintaining the confidentiality of your digital conversations and safeguarding critical data. Privacy Your inbox is a vault of private interactions, ranging from personal chats to confidential business dealings. Unauthorised intrusion into your email can severely compromise your privacy. Implementing stringent security measures is essential to protect your personal data from prying eyes. We share how below. Data Integrity Ensuring the integrity of your emails is vital. It guarantees that the information relayed remains authentic and unaltered during transmission. Strong email security protocols can thwart unauthorised changes, thus maintaining the reliability and authenticity of your digital correspondence. Protection Against Malware and Phishing Attacks Email is a common conduit for cyber-attacks, including malware and phishing schemes. Cybercriminals often deploy sophisticated methods to deceive and gain unauthorised access to sensitive data. Robust email security measures are crucial in detecting and intercepting suspicious emails, reducing the risk of such attacks. Compliance with Regulations Various industries enforce regulations to safeguard sensitive data. Compliance is essential to avoid legal repercussions and reputational harm. Strong email security practices help businesses meet these requirements, protecting their customers’ and partners’ sensitive information. Stay a step ahead of malicious actors Get Quote Best Practices for Email Security Strong Passwords Use complex, unique passwords for email accounts. It’s one of the easiest ways to protect yourself, yet many people still use passwords that can be easily deciphered. Avoid predictable information like birth dates. Password managers can aid in generating and securely storing robust passwords. Two-Factor Authentication (2FA) Enhance security by enabling 2FA. This requires a secondary verification method, such as a text message or app, in addition to your password. This is vital even if your password is compromised. Beware of Phishing Emails Be cautious with emails that request personal info or urge you to click on dubious links. Look out for signs of phishing like misspellings, odd URLs or undue urgency. Verify the email’s legitimacy through a separate channel if in doubt. Regular Updates Keep your email client, antivirus, and operating systems updated. This protects against known vulnerabilities. Install updates promptly for the latest security enhancements. Email Encryption Encrypt sensitive emails for an additional security layer, ensuring only the intended recipient can view the content. Utilise your email provider’s encryption options or third-party tools for heightened security. Regular Backups Back up your emails to protect against accidental deletion or security breaches. Cloud-based solutions or local backups can ensure message and attachment recovery. Caution on Public Wi-Fi Avoid accessing email on public Wi-Fi networks to prevent data interception. Use a VPN for a secure connection when necessary. Why Is Email the Number 1 Attack Vector? Emails are a prevalent initial infection vector due to their universal use and the volume of emails employees handle. This creates a false sense of security, which cybercriminals exploit through phishing attacks. With the growth of cloud-based email, these attacks have become more frequent and effective. The Phishing Threat Phishing emails exploit social engineering to target organisation employees. These emails can lead to credential theft, installation of malware, or broader network access for cybercriminals. Over 90% of cyberattacks start with a phishing email, underscoring their effectiveness. Exploiting Cloud Email The rise of cloud computing has opened new attack vectors via cloud-based email and document sharing services. Attackers often masquerade phishing emails as legitimate shared documents to steal credentials and access sensitive company data. The Potential Damage of Malicious Emails Phishing emails can result in credential theft, fraudulent payments, Trojan installations, or ransomware delivery. These attacks only require one employee to be successful, but often target multiple employees to increase their chances. Why Built-In Security Isn’t Enough Many organisations rely on default security settings from their email providers, which are insufficient against various threats like zero-day malware, social engineering and employee negligence. Comprehensive email security solutions must go beyond these basic measures to effectively counteract sophisticated cyber threats. Advanced Threat Protection Utilising advanced threat protection (ATP) tools is essential in identifying and neutralising sophisticated email threats. ATP solutions use machine learning and heuristics to detect anomalies and patterns indicative of malicious activity, providing a more dynamic defence against evolving cyber threats. User Education and Awareness One of the most effective defences against email-based threats is an informed and vigilant workforce. Regular training sessions on identifying phishing attempts, safe email practices, and the importance of security protocols can significantly reduce the risk of successful cyber attacks. Regular Security Audits Conducting periodic security audits of your email systems can reveal vulnerabilities and compliance issues. These audits should assess all aspects of email security, from infrastructure to user practices, ensuring that every component of your email ecosystem is secure.

What is Spear Phishing?
What is Spear Phishing? It is considered to be the most potent form of attack, learn how you can prevent these attacks. Get a Quote Download Datasheet Email Security >Phishing What is Spear Phishing? Among different cyberattacks, spear phishing poses the most potent threat. Unlike standard “Spray and Pray” phishing, spear phishing is a highly targeted and deceptive form of attack. It integrates sophisticated social engineering techniques, often going unnoticed by its target. In addition, according to Symantec’s Internet Security Threat Report(ISTR), 65% of attackers relied on spear phishing attacks. So, it’s highly important to understand what spear phishing is to create a protective shield against it. By Cian Fitzpatrick | 16th November, 2023 Spear Phishing Definition Spear phishing is a type of phishing attack that targets highly specific individuals or roles within an organisation to acquire sensitive information. Spear phishing is much more effective than a standard phishing attack. The attacker does intensive research on their target and uses social engineering techniques to craft a message to make it seem to be from a legitimate source. For instance, they collect personal information about a target and send messages disguising themself as a trustworthy friend to acquire sensitive information. Types of Spear Phishing Attacks Some of the major spear phishing types are: 1. Whaling Phishing It is a highly targeted attack that targets high-profile or high-ranking individuals such as C-suite executives or board members. It also involves non-corporate targets such as celebrities or politicians. Attackers aim to fetch large sums of cash or acquire confidential information that can be used against them—no wonder it requires more research than any other form of spear phishing attacks. 2. Business Email Compromise(BEC) CEO Fraud The threat actors impersonate or hack into the email account of a senior executive, typically a CEO. And instruct lower-level employees to wire money into fraudulent accounts by creating a sense of urgency to make them act abruptly. Email Account Compromise(EAC) Attackers gain access to lower-level employees to send fraudulent emails and trick other employees into sharing confidential information. EAC is often used to acquire the credentials of senior executives to perform CEO fraud. Barrel Phishing It is a phishing attack where scammers send emails to a large number of recipients, pretending to be from a legitimate source. The scammers anticipate that at least one recipient will click on the link to steal sensitive information. Try Our Phishing Simulator Now Get Quote How Does Spear Phishing Attack Work? Spear phishing attack works in various stages; they are: Selection of Target Scammers choose individuals or organisations they want to target based on their goals, whether their goal is to gain large sums of money or sensitive information. Use of Reconnaissance Technique Before commencing the attack, the scammer gathers detailed information about the victim using social media platforms. Crafting Email By using gathered information, scammers craft a personalised email to make it look as if it’s from a legitimate source. This causes the target to immediately lower their guard. For instance, it could be a coworker, manager, or a trustworthy friend of the target. Call to Action Fraudulent emails often have a call to action to create a sense of urgency to ensure the attack works 100% of the time. In the heat of the moment, the target will click the link or download an attachment. This action can lead to serious consequences, including identity theft, data breaches, ransomware attacks, corporate espionage, etc. Covering Footprints After the attack, the scammer removes every trace of the attack to evade detection and prolongs access to the system. Common Targets of Spear Phishing Attacks Spear phishing attacks involve detailed research of a high-value or high-profile individual. Even though they are often time-consuming, they yield a higher anticipated reward than standard phishing attacks. Commonly targeted individuals of spear phishing attacks are: High profile individual Scammers target high-profile individuals like CEOs, politicians or celebrities to steal their sensitive information. Lower-level or New Employees Lower-level or newer employees often fall victim to phishing attacks, as they are frequently unaware of policies or procedures they must follow to prevent spear phishing attempts. Specific Group or Types of Employees Scammers target employees with access to sensitive or confidential information, such as HR or finance executives. Learn how you can protect your staff Contact Us Spear Phishing Characteristics Some of the characteristics of spear phishing are: Targeted Recipients Spear phishing employs highly personalised messages to target specific individuals or organisations. These messages focus on high-profile or high-value individuals, promising substantial rewards. Spear phishing targets specific individuals, unlike standard phishing, which targets a high volume of individuals. Personalised Messages Scammers on various social media platforms conduct intensive research on their targets to formulate emails that create a sense of familiarity, often leading to the disclosure of sensitive information. Sophisticated Tactics and Techniques Scammers use reconnaissance and social engineering techniques to carry out spear phishing attacks. The reconnaissance technique involves intensive gathering of information on a target. At the same time, social engineering techniques involve the manipulation of personality traits to make the target perform a certain action. Common Objectives Spear phishing takes on various forms, but the goal remains the same: extracting sensitive information such as credentials or credit card information. Links to Malicious Websites or Files Scammers use phishing emails, which include links to malicious websites or files created by threat actors, to extract sensitive information when recipients click on them. Common Techniques Used in Spear Phishing Attacks Some of the characteristics of spear phishing are: Social Engineering Techniques Spear phishing attacks thrive on social engineering techniques. They manipulate personality traits such as desire to be helpful or curiosity about events or news. Individuals let their guard down easily with this technique, enabling threat actors to leverage the situation to extract sensitive information. Suspicious Emails and Phone Calls Attackers, using generic or misspelt domains in their emails, disguise themselves as legitimate entities to reach out to their targets through emails and phone calls. Malicious Emails with Attachments or Links
What is a DMARC Record?
What is A DMARC Record? Know the components of a DMARC record and it’s importance Get a Quote Download Datasheet Email Security > DMARC What is a DMARC Record? In today’s digital landscape, implementing DMARC records to tackle the rising threat of cyberattacks is of utmost importance. These attacks jeopardise sensitive information and put entities interacting with your company at risk. However, you can eradicate this risk by implementing the DMARC record. These records act as robust shields, instructing recipient servers on handling emails that fail authentication checks. By quarantining or rejecting suspicious emails, it provides a much-needed layer of defence. By Cian Fitzpatrick | 16th November, 2023 What is the Purpose of a DMARC Record? A DMARC record has two main purposes. They are: Instruct the recipient server It guides the recipient server on what to do if the email fails authentication checks like: Reject the message Quarantine the message Allow the message to continue the delivery 2. Send the reports Reports are sent to the email address mentioned in the DMARC record about all email activities associated with the domain. What does a DMARC Record Look Like? Creating a DMARC record ensures servers can distinguish between legitimate and fake emails. As a result, it protects against various security threats, such as phishing, spoofing, and spamming. Before getting started, we need to learn about DMARC TXT Record tags. Tags Meaning V It represents the protocol version. For example, v=DMARC1 pct It is the percentage of messages subjected to filtering. It ranges from 0 to 100. ruf It indicates the reporting URL for forensic reports. rua It indicates the reporting URL for aggregate reports p It is the policy for the organisational domain. It includes three types of policy. “p=none”“p=quarantine” “p=reject” sp Policy for a subdomain of the organisational domain. adkim Alignment mode for DKIM. aspf Alignment mode for SPF fo Get email samples for messages that fail SPF and DKIM. You can choose four values; “0” if SPF and DKIM fail (Default) “1” if SPF or DKIM fails “d” DKIM failure “S” SPF failure Try our 7 day free DMARC trial now Sign Up Now What DMARC Record Looks Like? Typically, DMARC records consist of plain text, a list of DMARC tags segregated by semicolons. It consists of atleast three components, but you can add other optional tags as per need. It’s necessary to place “v” and “p” tags at the beginning; other tags can follow any order. To get in-depth insight, let’s break down the example of a DMARC record and learn it piece by piece. “v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com” We have three mandatory tags, v, p and rua, with the values DMARC1, none and mailto:dmarc@yourdomain.com. The v tag indicates the version of DMARC. The p tag is the policy that indicates what action the receiver should take if the message fails the authentication checks. The rua tag sends aggregate reports to a specified email. The prefix mailto: should be added before writing an email address. Based on specific requirements or needs, you can use other tags like pct, ruf, fo, etc. DMARC Policy: If your message fails the authentication check, you can specify what actions to take in the policy(p) tag. There are 3 types of policy you can choose from: Monitoring Policy (“p=none“) This policy doesn’t give any protection. But emails are constantly monitored. Generally, during the initial implementation process of DMARC, emails are monitored. Gradually, it is upgraded to quarantine and finally reaches the reject stage. Quarantine Policy(“p=quarantine”) It places emails that fail authentication checks in the spam or quarantine folder. Reject policy (“p=reject“) It immediately rejects emails that fail the authentication check. It protects against fraudulent mail by not giving a single chance to reach the recipient’s email. Why are DMARC Records Important? DMARC has grown from a mere option to the absolute necessity for email security and protection against cyber attacks such as email spoofing and phishing attacks. With the surge in technology, the threat actors have come up with new sophisticated techniques to steal company identity and deceive customers and employees. By implementing DMARC, you’re defending against constantly lurking threats. Improved Email Delivery Performance Even your legitimate emails may fail to reach the recipient server’s inbox. To amend this, you can use the DMARC record, which helps to identify and fix any authentication issues. As a result, email delivery performance is enhanced. Reduced Phishing and Spoofing Attacks It is a primary defence against cyberattacks like phishing, spoofing, and identity theft. In addition, it helps domain owners prevent unauthorised parties from sending emails on their behalf. It protects not only the company but also the customers associated with it. Enhanced Brand Protection and Reputation Building a brand doesn’t happen overnight, yet a single mistake can cause your brand to crumble like a chain of falling dominoes. Not only will your company suffer, you’ll likely lose hard-earned loyal customers. In addition to that, your reputation will take a direct hit, and sometimes, it’s impossible to build your reputation the way it was. DMARC record prevents bad actors from impersonating your brand’s domain. It ensures that your employees and customers get only legitimate emails. Furthermore, it will enhance your credibility as a brand that prioritises protecting your customers’ interests. Increased Visibility into Email Sending Behaviour The DMARC record provides ongoing data about the use of your domain, and it also aids in identifying threat actors that impersonate your domain. Moreover, the reporting mechanism of DMARC will instantly recognise if someone is misusing your domain. More Control Over How Your Domain is Used Implementing DMARC records in your domain’s DNS enables you to gather information about the entities sending emails on your behalf. DMARC record eradicates this risk and prevents your domain from being used for malicious purposes. Learn how you can be DMARC compliant Contact Us How Does a DMARC Record Work?
