Remove Win32/Filecoder.OCA Virus

Win32/Filecoder.OCA is a detection name used by ESET NOD32 to identify a specific type of ransomware. Antivirus uses these names to classify and alert users to the presence of potentially harmful viruses like ransomware on their computer systems.

In this case, “Win32” indicates that the malware is designed to run on Windows operating systems, and “Filecoder” suggests that it is a type of ransomware that encrypts files on the infected system. The “.OCA” portion of the detection name is likely a variant or version identifier assigned by the antivirus software to distinguish this particular strain of ransomware from others.

If your antivirus software has detected “Win32/Filecoder.OCA” on your system, it’s essential to follow the recommended actions provided by your antivirus program. This typically involves quarantining or removing the infected files and taking steps to restore or recover any encrypted data if possible. Additionally, it’s crucial to keep your antivirus software up to date and practice good cybersecurity hygiene to reduce the risk of future infections.

What is Win32/Filecoder.OCA virus?

Win32/Filecoder.OCA is ransomware-type malware. It looks for the files on your computer, encrypts them, and then asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware also does a lot of damage to your system. It modifies the networking setups in order to prevent you from reading the removal manuals or downloading the anti-malware program. In rare cases, Win32/Filecoder.OCA can also prevent the launching of anti-malware programs.

Win32/Filecoder.OCA Summary

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

• A file was accessed within the Public folder.;
• Access the NetLogon registry key, potentially used for discovery or tampering;
• CAPE extracted potentially suspicious content;
• The binary contains an unknown PE section name indicative of packing;
• Authenticode signature is invalid;
• CAPE detected the Conti malware family;
• Creates a known ContiV2 ransomware decryption instruction/key file.;
• Yara rule detections observed from a process memory dump/dropped files/CAPE;
• Ciphering the files located on the target’s disk drives — so the victim cannot use these files;
• Blocking the launching of .exe files of anti-malware programs
• Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a headache for the last 4 years. It is difficult to imagine a more dangerous malware for both individual users and companies. The algorithms used in Win32/Filecoder.OCA (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with brute force, you need to have a lot more time than our galaxy currently exists, and possibly will exist. But that virus does not do all these terrible things immediately – it can require up to a few hours to cipher all of your files. Thus, seeing the Win32/Filecoder.OCA detection is a clear signal that you need to start the removal process.
