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

Trojan:MSIL/AgentTesla.RCK!MTB is ransomware-type malware. It looks for the documents on your disk drive, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus additionally does a ton of damage to your system. It changes the networking setups in order to avoid you from looking for the removal guidelines or downloading the anti-malware program. In rare cases, Trojan:MSIL/AgentTesla.RCK!MTB can additionally prevent the setup of anti-malware programs.

Trojan:MSIL/AgentTesla.RCK!MTB Summary

In summary, Trojan:MSIL/AgentTesla.RCK!MTB virus actions in the infected system are next:

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

Ransomware has actually been a horror story for the last 4 years. It is challenging to picture a more damaging malware for both individual users and companies. The algorithms utilized in Trojan:MSIL/AgentTesla.RCK!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy already exists, and possibly will exist. But that malware does not do all these unpleasant things immediately – it may take up to a few hours to cipher all of your documents. Thus, seeing the Trojan:MSIL/AgentTesla.RCK!MTB detection is a clear signal that you need to start the elimination process.

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

Typical ways of Trojan:MSIL/AgentTesla.RCK!MTB distribution are standard for all other ransomware examples. Those are one-day landing sites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty new method in malware spreading – you receive the email that simulates some routine notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite uncomplicated, however, still demands a lot of awareness. Malware can hide in different spots, and it is much better to stop it even before it goes into your system than to trust in an anti-malware program. Simple cybersecurity awareness is just an important item in the modern world, even if your relationship with a computer remains on YouTube videos. That can save you a lot of money and time which you would spend while trying to find a fix guide.
