It frequently shows up after the provoking activities on your PC – opening the suspicious email messages, clicking the advertisement in the Web or mounting the program from unreliable sources.

What is Win32/Autoit.OHY virus?

Win32/Autoit.OHY is ransomware-type malware. It searches for the documents on your disks, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware additionally does a ton of harm to your system. It alters the networking setups in order to stop you from reading the elimination guidelines or downloading the anti-malware program. Sometimes, Win32/Autoit.OHY can also block the launching of anti-malware programs.

Win32/Autoit.OHY Summary

Summarizingly, Win32/Autoit.OHY ransomware actions in the infected system are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • Authenticode signature is invalid;
  • Ciphering the files located on the victim’s disks — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has actually been a nightmare for the last 4 years. It is challenging to realize a more damaging malware for both individual users and companies. The algorithms utilized in Win32/Autoit.OHY (typically, 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 already exists, and possibly will exist. However, that malware does not do all these unpleasant things instantly – it may take up to a few hours to cipher all of your files. Therefore, seeing the Win32/Autoit.OHY detection is a clear signal that you should start the elimination procedure.

Where did I get the Win32/Autoit.OHY?

Routine ways of Win32/Autoit.OHY injection are basic for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait emails and hacktools. Bait e-mails are a pretty new strategy in malware spreading – you receive the email that imitates some standard notifications about deliveries or bank service conditions shifts. Inside of the email, there is an infected 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.

Avoiding it looks pretty uncomplicated, however, still requires tons of awareness. Malware can hide in different spots, and it is much better to stop it even before it goes into your PC than to rely on an anti-malware program. Essential cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while trying to find a solution.
