What is Trojan:MSIL/AsyncRAT.RDW!MTB virus?

Trojan:MSIL/AsyncRAT.RDW!MTB is ransomware-type malware. It looks for the files on your disk drives, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this malware also does a ton of damage to your system.

In rare cases, Trojan:MSIL/AsyncRAT.RDW!MTB can even block the setup of anti-malware programs.

Trojan:MSIL/AsyncRAT.RDW!MTB Summary

In total, Trojan:MSIL/AsyncRAT.RDW!MTB malware 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 kept on the target’s drives — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a headache for the last 4 years. It is hard to picture a more dangerous virus for both individuals and companies. The algorithms used in Trojan:MSIL/AsyncRAT.RDW!MTB (generally, 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. But that malware does not do all these unpleasant things instantly – it may take up to several hours to cipher all of your documents. Hence, seeing the Trojan:MSIL/AsyncRAT.RDW!MTB detection is a clear signal that you have to start the clearing procedure.

Where did I get the Trojan:MSIL/AsyncRAT.RDW!MTB?

Routine methods of Trojan:MSIL/AsyncRAT.RDW!MTB distribution are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a pretty modern tactic in malware spreading – you receive the e-mail that mimics some routine notifications about shippings or bank service conditions modifications. Inside of the email, there is a corrupted MS Office file, or a web 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 pretty easy, but still requires tons of recognition. Malware can hide in different places, and it is far better to stop it even before it goes into your system than to depend on an anti-malware program. Standard cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a PC stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while trying to find a fix guide.
