Win32/Filecoder.NUQ detection is a malware detection you can spectate in your system. It often shows up after the preliminary procedures on your computer – opening the dubious e-mail messages, clicking the banner in the Web or installing the program from suspicious sources. From the second it appears, you have a short time to act before it starts its malicious activity. And be sure – it is better not to wait for these harmful things.

What is Win32/Filecoder.NUQ virus?

Win32/Filecoder.NUQ is ransomware-type malware. It looks for the files on your disk, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this virus additionally does a lot of damage to your system. It alters the networking setups in order to stop you from looking for the removal manuals or downloading the anti-malware program. In some cases, Win32/Filecoder.NUQ can even stop the launching of anti-malware programs.

Win32/Filecoder.NUQ Summary

In total, Win32/Filecoder.NUQ malware actions in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • 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;

  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a horror story for the last 4 years. It is challenging to realize a more hazardous malware for both individual users and organizations. The algorithms used in Win32/Filecoder.NUQ (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 already exists, and possibly will exist. But that virus does not do all these bad things without delay – it may take up to a few hours to cipher all of your documents. Thus, seeing the Win32/Filecoder.NUQ detection is a clear signal that you have to start the removal procedure.

Where did I get the Win32/Filecoder.NUQ?

Common ways of Win32/Filecoder.NUQ distribution are standard for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait emails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the email that imitates some routine notifications about shipments or bank service conditions shifts. Within the email, 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.

Avoiding it looks pretty uncomplicated, but still needs a lot of focus. Malware can hide in different spots, and it is better to prevent it even before it goes into your system than to rely on an anti-malware program. Common cybersecurity awareness is just an important item in the modern world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of money and time which you would spend while searching for a fix guide.
