Win32/Filecoder.OKE is ransomware-type malware. It searches for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for getting the decryption key.

  • Access the NetLogon registry key, potentially used for discovery or tampering;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;

  • Uses suspicious command line tools or Windows utilities;
  • Encrypting the documents kept on the target’s drives — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-malware programs

Ransomware has actually been a major problem for the last 4 years. It is difficult to imagine a more damaging malware for both individual users and corporations. The algorithms utilized in Win32/Filecoder.OKE (typically, 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.

Where did I get the Win32/Filecoder.OKE?

Ordinary ways of Win32/Filecoder.OKE spreading are standard for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware spreading – you get the email that imitates some normal notifications about shippings or bank service conditions shifts. Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks quite uncomplicated, but still demands tons of recognition. Malware can hide in various places, and it is far better to prevent it even before it goes into your PC than to trust in an anti-malware program. Common cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a computer remains on YouTube videos. That can save you a lot of time and money which you would spend while seeking a fix guide.
