It usually appears after the provoking actions on your PC – opening the untrustworthy e-mail messages, clicking the banner in the Internet or setting up the program from suspicious sources.

What is Win32/Filecoder.Hydra.A virus?

Win32/Filecoder.Hydra.A is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this malware also does a lot of harm to your system. It modifies the networking setups in order to stop you from checking out the removal manuals or downloading the antivirus. In some cases, Win32/Filecoder.Hydra.A can also block the setup of anti-malware programs.

Win32/Filecoder.Hydra.A Summary

Summarizingly, Win32/Filecoder.Hydra.A virus activities in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Dynamic (imported) function loading detected;
  • Starts servers listening on 127.0.0.1:0;
  • Manipulates data from or to the Recycle Bin;
  • The binary contains an unknown PE section name indicative of packing;
  • Creates an autorun.inf file;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;
  • Attempts to interact with an Alternate Data Stream (ADS);

  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a horror story for the last 4 years. It is challenging to realize a more dangerous virus for both individuals and companies. The algorithms utilized in Win32/Filecoder.Hydra.A (usually, 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 malware does not do all these horrible things immediately – it may require up to several hours to cipher all of your documents. Therefore, seeing the Win32/Filecoder.Hydra.A detection is a clear signal that you need to begin the removal procedure.

Where did I get the Win32/Filecoder.Hydra.A?

Common methods of Win32/Filecoder.Hydra.A distribution are common for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern method in malware distribution – you get the email that imitates some standard notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a malicious 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.

Avoiding it looks quite simple, however, still requires a lot of focus. Malware can hide in various spots, and it is better to stop it even before it invades your system than to rely on an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a computer remains on YouTube videos. That may save you a great deal of money and time which you would spend while trying to find a fix guide.
