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

Trojan:MSIL/AgentTesla.CB!MTB is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware additionally does a ton of harm to your system. It alters the networking settings in order to stop you from reading the removal guidelines or downloading the anti-malware program. In some cases, Trojan:MSIL/AgentTesla.CB!MTB can even stop the setup of anti-malware programs.

Trojan:MSIL/AgentTesla.CB!MTB Summary

In summary, Trojan:MSIL/AgentTesla.CB!MTB ransomware activities in the infected computer are next:

  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Encrypting the documents located on the victim’s disk — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a nightmare for the last 4 years. It is difficult to picture a more damaging malware for both individual users and businesses. The algorithms utilized in Trojan:MSIL/AgentTesla.CB!MTB (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy currently exists, and possibly will exist. However, that malware does not do all these terrible things without delay – it can take up to a few hours to cipher all of your files. Thus, seeing the Trojan:MSIL/AgentTesla.CB!MTB detection is a clear signal that you should start the clearing process.

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

Typical tactics of Trojan:MSIL/AgentTesla.CB!MTB distribution are basic for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a relatively modern tactic in malware distribution – you receive the email that imitates some normal notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks quite simple, however, still requires tons of recognition. Malware can hide in different places, and it is better to prevent it even before it goes into your PC than to trust in an anti-malware program. Simple cybersecurity awareness is just an essential thing in the modern world, even if your relationship with a PC remains on YouTube videos. That can save you a great deal of time and money which you would spend while looking for a fixing guide.
