Win32/TrojanDownloader.AutoHK.GS detection is a malware detection you can spectate in your system. It often appears after the preliminary actions on your computer – opening the suspicious email, clicking the advertisement in the Internet or mounting the program from untrustworthy resources. From the second it appears, you have a short time to take action until it begins its destructive activity. And be sure – it is much better not to wait for these harmful effects.

What is Win32/TrojanDownloader.AutoHK.GS virus?

Win32/TrojanDownloader.AutoHK.GS is ransomware-type malware. It looks for the documents on your computer, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this malware also does a lot of harm to your system. It changes the networking setups in order to prevent you from looking for the removal manuals or downloading the antivirus. In rare cases, Win32/TrojanDownloader.AutoHK.GS can also block the launching of anti-malware programs.

Win32/TrojanDownloader.AutoHK.GS Summary

Summarizingly, Win32/TrojanDownloader.AutoHK.GS malware actions in the infected computer are next:

  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • The executable is compressed using UPX;
  • Authenticode signature is invalid;
  • Attempts to repeatedly call a single API many times in order to delay analysis time;
  • Attempts to modify proxy settings;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the files kept on the victim’s disks — so the victim cannot use these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a horror story for the last 4 years. It is difficult to picture a more damaging virus for both individual users and corporations. The algorithms utilized in Win32/TrojanDownloader.AutoHK.GS (typically, 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 already exists, and possibly will exist. However, that virus does not do all these unpleasant things immediately – it may require up to a few hours to cipher all of your documents. Thus, seeing the Win32/TrojanDownloader.AutoHK.GS detection is a clear signal that you have to start the elimination process.

Where did I get the Win32/TrojanDownloader.AutoHK.GS?

Routine ways of Win32/TrojanDownloader.AutoHK.GS injection are basic 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 emails and hacktools. Bait e-mails are a relatively new strategy in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions updates. Inside of the email, 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 quite easy, but still demands tons of focus. Malware can hide in various spots, and it is better to stop it even before it gets into your system than to rely on an anti-malware program. Common cybersecurity knowledge is just an essential thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may save you a lot of time and money which you would certainly spend while trying to find a solution.
