What is Win32/TrojanDownloader.Busky.AZ virus?

Win32/TrojanDownloader.Busky.AZ is ransomware-type malware. It looks for the documents on your disk, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this virus also does a ton of damage to your system.

Sometimes, Win32/TrojanDownloader.Busky.AZ can even prevent the launching of anti-malware programs.

Win32/TrojanDownloader.Busky.AZ Summary

In summary, Win32/TrojanDownloader.Busky.AZ malware actions in the infected system are next:

  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Ciphering the documents kept on the victim’s disk drive — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a nightmare for the last 4 years. It is challenging to realize a more dangerous malware for both individuals and companies. The algorithms used in Win32/TrojanDownloader.Busky.AZ (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these terrible things instantly – it can require up to several hours to cipher all of your documents. Therefore, seeing the Win32/TrojanDownloader.Busky.AZ detection is a clear signal that you should begin the removal process.

Where did I get the Win32/TrojanDownloader.Busky.AZ?

Routine methods of Win32/TrojanDownloader.Busky.AZ spreading are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern method in malware spreading – you receive the email that simulates some regular notifications about shippings or bank service conditions changes. Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks pretty simple, but still requires tons of attention. Malware can hide in various places, and it is much better to stop it even before it gets into your computer than to rely on an anti-malware program. Common cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a computer stays on YouTube videos. That may save you a lot of time and money which you would certainly spend while looking for a fixing guide.
