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

Win32:Agent-ASLA [Trj] is ransomware-type malware. It searches for the files on your disk, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware also does a ton of harm to your system. It changes the networking settings in order to avoid you from checking out the removal guidelines or downloading the antivirus. Sometimes, Win32:Agent-ASLA [Trj] can even prevent the launching of anti-malware programs.

Win32:Agent-ASLA [Trj] Summary

In total, Win32:Agent-ASLA [Trj] malware activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Unconventionial binary language: Russian;
  • Authenticode signature is invalid;
  • Ciphering the files located on the target’s disk drive — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus programs

Ransomware has been a nightmare for the last 4 years. It is difficult to realize a more dangerous virus for both individual users and businesses. The algorithms utilized in Win32:Agent-ASLA [Trj] (typically, 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 virus does not do all these horrible things immediately – it may require up to several hours to cipher all of your documents. Hence, seeing the Win32:Agent-ASLA [Trj] detection is a clear signal that you have to start the removal procedure.

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

Routine methods of Win32:Agent-ASLA [Trj] injection are typical for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free software, so-called bait emails and hacktools. Bait emails are a quite modern method in malware distribution – you receive the e-mail that simulates some routine notifications about shipments or bank service conditions modifications. Inside of the e-mail, there is an infected 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.

Preventing it looks pretty simple, however, still demands a lot of recognition. Malware can hide in different spots, and it is far better to prevent it even before it invades your computer than to depend on an anti-malware program. General cybersecurity knowledge is just an essential item in the modern-day world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of money and time which you would spend while searching for a fix guide.
