The 3 Types Of Email Threats That Are The Hardest To Detect

In the contemporary digital ecosystem, the threat of malicious emails remains omnipresent. Moreover, some stand out by their subtlety and complexity. Among these, three categories of email threats present unique detection challenges for users. Indeed, the employees’ ability to distinguish legitimate exchanges and dangerous communications remains crucial for the protection of organizations. While some businesses make significant investments in advanced security infrastructures, many others neglect this essential component. 

Compromise Of Business Emails

An insidious threat, the compromise of business emails occurs when individuals pretend to be legitimate members of an organization or affiliates to solicit precious information such as money or identification data. 

Why is it hard to detect this threat?

The emails are usually designed to imitate the routine communications of those concerned, with a touch of urgency to prompt a quick response. Furthermore, the use of mobile devices to send these communications can justify typing errors or formatting irregularities, thus reinforcing their perceived legitimacy. Lastly, the lack of knowledge of the personal emails of colleagues or supervisors often makes recipients less inclined to question the authenticity of these communications, especially if the names seem correct in the header and signature.

Conversation Hack

This occurs after a cybercriminal has already infiltrated an internal account. By acting this way, he inserts himself in a legitimate exchange by creating a similar domain and effectively deleting any compromising trace, thereby also isolating the discussion thread of the hacker and his new target. 

Why is it hard to detect this threat?

The victim already has a trusting relationship with a legitimate recipient of the conversation, which makes the hacker’s manipulation less suspicious. Often, the only noticeable difference lies in a subtle variation of the email address or the compromised domain. If the correspondent is on a mobile device, is distracted or does not carefully verify the sender’s contact information, he then becomes vulnerable to this clever move.

Identify Theft

Service identity theft occurs when hackers pretend to be familiar applications, thereby prompting users to give them log-in information or other critical data. As for brand hijacking, it occurs when cybercriminals operate stolen domains to pretend to be well-known companies. 

Why is it hard to detect this threat?

Users are often used to receiving genuine emails from popular sites asking them to re-enter their identification information. These types of requests therefore seem legitimate, prompting victims to click on the fraudulent links that lead them to phishing platforms, without paying much attention.

In this environment with various security postures, the final user remains the common link targeted by criminals. This is why it is so important to raise awareness and to provide continuing education to company employees. Let our experts help you optimize your cybersecurity. Contact us for more information.
