It generally appears after the preliminary activities on your computer – opening the suspicious email, clicking the banner in the Internet or setting up the program from suspicious sources.

Trojan:MSIL/Seraph.AAUW!MTB is ransomware-type malware. It searches for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a ton of harm to your system.

In summary, Trojan:MSIL/Seraph.AAUW!MTB virus actions in the infected computer are next:

  • The binary likely contains encrypted or compressed data.;

The algorithms used in Trojan:MSIL/Seraph.AAUW!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 actually exists, and possibly will exist. However, that malware does not do all these unpleasant things without delay – it may take up to several hours to cipher all of your documents. Thus, seeing the Trojan:MSIL/Seraph.AAUW!MTB detection is a clear signal that you need to begin the elimination process.

General tactics of Trojan:MSIL/Seraph.AAUW!MTB spreading are standard for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a quite new tactic in malware spreading – you receive the email that simulates some standard notifications about shipments 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 site.

Malicious email spam

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

Preventing it looks pretty easy, but still needs a lot of awareness. Malware can hide in various places, and it is far better to prevent it even before it gets into your system than to rely on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That may keep you a lot of time and money which you would spend while looking for a fix guide.
