What is Trojan:Win32/Vundo!AA virus?

Trojan:Win32/Vundo!AA is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and then asks you to pay the ransom for getting the decryption key.

Trojan:Win32/Vundo!AA Summary

In total, Trojan:Win32/Vundo!AA virus actions in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Encrypting the files kept on the victim’s disk drives — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has been a headache for the last 4 years. It is difficult to realize a more damaging malware for both individual users and organizations. The algorithms utilized in Trojan:Win32/Vundo!AA (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 unpleasant things instantly – it may take up to a few hours to cipher all of your files.

Where did I get the Trojan:Win32/Vundo!AA?

Standard methods of Trojan:Win32/Vundo!AA injection are usual for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively new strategy in malware spreading – you receive the email that simulates some routine notifications about shipments or bank service conditions updates. Inside of the email, there is an infected 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.

Avoiding it looks pretty uncomplicated, but still requires tons of focus. Malware can hide in various places, and it is better to prevent it even before it goes into your system than to rely on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC stays on YouTube videos. That can keep you a lot of money and time which you would spend while searching for a fix guide.
