A comprehensive guide for Swiss companies on combating e-mail impersonation and spoofing

E-mail impersonation is a growing threat to companies in Switzerland. This type of attack can have serious consequences, from financial losses to the theft of sensitive data. In this blog post, we explain how you can recognise e-mail impersonation and protect yourself against it.

E-mail impersonation vs. e-mail spoofing

Although the two tactics are related, they are not quite the same. With e-mail impersonation, the cybercriminal creates an address that looks similar to the real one. With spoofing, the attacker changes the e-mail header so that a false e-mail address is displayed.

Types of e-mail impersonation

1. Root domain impersonation: Cybercriminals create root domains that resemble legitimate ones by using substitute characters.
2. Top-level domain impersonation: Here, the top-level domain (e.g. .ch for Switzerland) is replaced by another one that the recipient does not notice.
3. Subdomain impersonation: In this case, the subdomain is manipulated to imitate a legitimate e-mail address.
4. Display name impersonation: The display name is chosen to resemble the real name, which is often the case on well-known e-mail platforms.
5. Username impersonation: Here, a user name is created that looks similar to the real one but is hosted on a free e-mail platform.

Measures to protect against e-mail impersonation in Switzerland

1. Employee training: Training employees is crucial to preventing e-mail attacks.
2. Machine-intelligent e-mail security solutions: In Switzerland, companies such as SecureIT and Xorlab are leaders in providing intelligent e-mail security solutions.

Conclusion

E-mail impersonation remains one of the most insidious and potentially devastating cyber threats for companies in Switzerland. The variety of fraud methods, from root domain to username impersonation, shows that cybercriminals are becoming ever more sophisticated. It is therefore essential that companies not only rely on technological solutions but also invest in training their employees. Combining both creates a multi-layered defence strategy that minimises the likelihood of a successful attack.
Companies such as Xorlab are pioneers in the development of machine-intelligent e-mail security solutions, which play an important role in protecting against such attacks. But technology alone is not enough. A holistic approach that takes the human component into account is crucial for long-term protection against e-mail impersonation.
At a time when cyber threats are becoming increasingly complex, it is essential for Swiss companies to act proactively and to invest both technological and human resources in protecting their digital identities. Only in this way can they effectively arm themselves against the growing wave of e-mail impersonation and protect their business processes and sensitive data.
