What is Win32:Agent-ASEF [Trj] virus?

Win32:Agent-ASEF [Trj] is ransomware-type malware. It looks for the files on your computer, encrypts it, and after that asks you to pay the ransom for receiving the decryption key.

Win32:Agent-ASEF [Trj] Summary

In total, Win32:Agent-ASEF [Trj] virus actions in the infected PC are next:

  • At least one process apparently crashed during execution;
  • Dynamic (imported) function loading detected;
  • Reads data out of its own binary image;
  • Authenticode signature is invalid;

  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a nightmare for the last 4 years. It is challenging to imagine a more damaging virus for both individuals and companies. The algorithms utilized in Win32:Agent-ASEF [Trj] (generally, 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. But that virus does not do all these terrible things without delay – it can require up to several hours to cipher all of your documents.

Where did I get the Win32:Agent-ASEF [Trj]?

Ordinary ways of Win32:Agent-ASEF [Trj] injection are common for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a quite new tactic in malware distribution – you receive the email that simulates some routine notifications about shippings or bank service conditions shifts. Within the e-mail, there is a malicious 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 pretty easy, however, still demands a lot of attention. Malware can hide in different places, and it is far better to stop it even before it gets into your system than to rely on an anti-malware program. Standard cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That can keep you a lot of time and money which you would certainly spend while seeking a solution.
