What is Trojan:MSIL/AgentTesla.EXS!MTB virus?

Trojan:MSIL/AgentTesla.EXS!MTB is ransomware-type malware. It looks for the files on your disk drives, encrypts it, and then asks you to pay the ransom for receiving the decryption key.

Trojan:MSIL/AgentTesla.EXS!MTB Summary

  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;

The algorithms utilized in Trojan:MSIL/AgentTesla.EXS!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these bad things without delay – it may take up to several hours to cipher all of your documents.

Where did I get the Trojan:MSIL/AgentTesla.EXS!MTB?

Typical methods of Trojan:MSIL/AgentTesla.EXS!MTB injection are basic for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free program, so-called bait emails and hacktools. Bait emails are a pretty new strategy in malware distribution – you get the e-mail that imitates some regular notifications about shippings or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly easy, but still requires a lot of awareness. Malware can hide in different spots, and it is far better to prevent it even before it invades your PC than to depend on an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a great deal of time and money which you would spend while seeking a solution.
