What is Win32/Filecoder.OJC virus?

Win32/Filecoder.OJC is ransomware-type malware. It searches for the files on your disk drive, ciphers 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. It changes the networking setups in order to prevent you from checking out the elimination guidelines or downloading the antivirus. In rare cases, Win32/Filecoder.OJC can even stop the setup of anti-malware programs.

Win32/Filecoder.OJC Summary

Summarizingly, Win32/Filecoder.OJC ransomware actions in the infected PC are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Possible date expiration check, exits too soon after checking local time;
  • Dynamic (imported) function loading detected;
  • Enumerates running processes;
  • Manipulates data from or to the Recycle Bin;
  • A process created a hidden window;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;
  • Attempts to delete or modify volume shadow copies;
  • Writes a potential ransom message to disk;
  • Modifies boot configuration settings;
  • Uses suspicious command line tools or Windows utilities;

  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a nightmare for the last 4 years. It is hard to picture a more harmful malware for both individuals and companies. The algorithms used in Win32/Filecoder.OJC (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 actually exists, and possibly will exist. But that malware does not do all these bad things immediately – it may take up to a few hours to cipher all of your files. Hence, seeing the Win32/Filecoder.OJC detection is a clear signal that you need to start the elimination process.

Where did I get the Win32/Filecoder.OJC?

General methods of Win32/Filecoder.OJC injection are standard for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a quite new method in malware distribution – you receive the email that simulates some normal notifications about shippings or bank service conditions changes. 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 needs a lot of awareness. Malware can hide in different places, and it is better to stop it even before it gets into your computer than to rely upon an anti-malware program. Essential cybersecurity knowledge is just an essential thing in the modern world, even if your interaction with a PC remains on YouTube videos. That can keep you a lot of money and time which you would spend while looking for a solution.
