The ever-evolving landscape of email-based threats continues to be a concern for individuals and organizations alike. As malicious actors adapt their tactics and probe for vulnerabilities in both humans and software, it is crucial to stay informed about the latest trends and techniques used by cybercriminals.

According to recent research, the United States is the top source of spam emails, followed by the U.K., Ireland, and Japan. This marks a significant change from previous years when Germany and Turkey were also dominant sources of spam emails. Interestingly, the countries that produce the most spam are also the ones most targeted by email-based attacks. This may be due to various socioeconomic factors or simply because cybercriminals are adapting their strategies to the vigilant defense efforts of organizations in these regions.

One emerging trend in email phishing is the use of QR code phishing, also known as “Quishing”. QR codes have become increasingly popular due to their convenience, but this very feature has made them a prime target for criminals. They use QR codes as bait to trick unsuspecting users into scanning them, leading to phishing sites that gather personal information. Cybercriminals are leveraging generative AI technologies to create convincing phishing emails in multiple languages, making it easier than ever to deceive users.

In addition, cybercriminals are using common phrases that mimic legitimate services in order to deceive users. Messages like “2FA authentication is outdated” or “your email is quarantined” may seem harmless, but they are often traps designed to trick users into revealing sensitive information. It is important for individuals to stay vigilant and be wary of any emails that request personal or financial information.

Another tactic that cybercriminals are using is brand spoofing, with Microsoft being the most commonly spoofed brand. With the majority of Fortune 500 companies using Microsoft Office 365, scammers find it easy to target users with fake emails and websites that resemble the legitimate Microsoft platform. Other popular brands for spoofing include DocuSign, eFax, and PayPal, as these services are commonly used for important document validation and online transactions.

Malicious spam is also on the rise, with threat actors using malspam emails to deliver malware or redirect users to malicious websites. Instead of relying solely on attachments, attackers are increasingly using malicious links within the body of the email. This tactic helps them avoid detection by email security tools and increases the chances of success. Additionally, malware is often hidden within cloud storage platforms such as Google Drive, making it harder to detect and remove.

To combat these evolving email threats, enterprises must adopt a multi-layered approach to security. This includes implementing secure email and endpoint protection solutions, utilizing threat intelligence to stay ahead of emerging threats, and providing continuous user awareness and security training. While Microsoft Office is widely used across organizations, it is important to recognize that the standard security measures offered by the platform have limitations. Layering on advanced email threat protection tools, such as link isolation and sandboxing capabilities, can help mitigate the risks associated with unknown zero-day threats.

Link isolation ensures that malicious URLs in emails are rendered harmless, while sandboxing allows suspicious attachments to be investigated in a safe environment. Additionally, adopting best-in-class third-party services to complement existing security measures can provide comprehensive protection against email-based attacks. While Microsoft offers security features in its solutions, it is not a specialist in email security. Therefore, organizations should consider partnering with specialized email security providers to maximize their defense against evolving threats.

In conclusion, the email threat landscape continues to evolve and pose risks to individuals and organizations. Staying informed about the latest trends and techniques used by cybercriminals is crucial for maintaining a strong defense. Implementing a multi-layered approach to security, including advanced email threat protection tools and partnerships with third-party security providers, can help mitigate the risks associated with these threats. By investing in robust security measures and maintaining continuous user awareness and training, enterprises can stay one step ahead of malicious actors and protect their sensitive information.
