Python/Filecoder.FC detection is a malware detection you can spectate in your system. It often shows up after the provoking activities on your computer – opening the dubious email messages, clicking the advertisement in the Internet or mounting the program from unreliable resources. From the second it appears, you have a short time to do something about it until it begins its harmful activity. And be sure – it is better not to wait for these harmful things.

What is Python/Filecoder.FC virus?

Python/Filecoder.FC is ransomware-type malware. It searches for the documents on your disks, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this malware also does a lot of damage to your system. It modifies the networking settings in order to stop you from reading the removal guidelines or downloading the anti-malware program. In rare cases, Python/Filecoder.FC can also prevent the setup of anti-malware programs.

Python/Filecoder.FC Summary

Summarizingly, Python/Filecoder.FC malware activities in the infected computer are next:

  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Dynamic (imported) function loading detected;
  • 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;
  • CAPE detected the PyInstaller malware family;
  • Ciphering the documents located on the target’s disk drive — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a nightmare for the last 4 years. It is challenging to realize a more harmful malware for both individuals and corporations. The algorithms used in Python/Filecoder.FC (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these unpleasant things instantly – it may require up to a few hours to cipher all of your files. Therefore, seeing the Python/Filecoder.FC detection is a clear signal that you have to start the removal process.

Where did I get the Python/Filecoder.FC?

Typical ways of Python/Filecoder.FC distribution are typical for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware distribution – you receive the e-mail that mimics some standard notifications about shipments or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks pretty simple, but still needs a lot of attention. Malware can hide in different spots, and it is much better to prevent it even before it gets into your computer than to trust in an anti-malware program. Common cybersecurity knowledge is just an essential thing in the modern world, even if your interaction with a PC stays on YouTube videos. That may save you a lot of money and time which you would certainly spend while seeking a fix guide.
