What’s the threat about?
The Cybersecurity Team of Masaryk University would like to inform you about an increased risk of being targeted by phishing e-mails. These e-mails contain a suspicious link to download an unknown file. Note that the presence of the download link in the e-mail is not explained in any way. By downloading this file, the user infects the device with very sophisticated malware.
Attackers proceed as follows: gain access to the e-mail address - find a trusted conversation in the inbox - send e-mails with a link to download an unknown file that contains malware. You can see an example in the red box in the picture below.
This current threat is a textbook case of what the average user encounters with a certain regularity. We, therefore, recommend the following digital habits:
- Don't click on links in e-mail messages.
- Never download files from unexpected e-mail attachments.
- Focus on just one activity at a time.
- Verify that the sender's name matches the e-mail address.
- If you receive a suspicious e-mail, please report it to the CSIRT-MU team.
In conclusion
In connection with the current situation, we would like to point out Cybercompass, our course about the fundamentals of information security for users. Especially its online lesson on Self-defense.
