What is Win32:Nabucur-C [Trj] virus?

Win32:Nabucur-C [Trj] is ransomware-type malware. It looks for the files on your disk drives, ciphers it, and then asks you to pay the ransom for receiving the decryption key.

Win32:Nabucur-C [Trj] Summary

Summarizingly, Win32:Nabucur-C [Trj] virus activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • At least one process apparently crashed during execution;
  • Creates RWX memory;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Ciphering the documents kept on the target’s disk drives — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-malware apps

The algorithms used in Win32:Nabucur-C [Trj] (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these unpleasant things instantly – it can take up to several hours to cipher all of your files. Thus, seeing the Win32:Nabucur-C [Trj] detection is a clear signal that you must start the removal procedure.

Where did I get the Win32:Nabucur-C [Trj]?

Standard tactics of Win32:Nabucur-C [Trj] injection are usual for all other ransomware examples. Those are one-day landing sites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a pretty modern tactic in malware spreading – you get the e-mail that mimics some regular notifications about shippings or bank service conditions updates. Inside of the e-mail, there is a corrupted MS Office file, or a web 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 pretty simple, however, still requires a lot of focus. Malware can hide in various spots, and it is better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Standard cybersecurity awareness is just an important thing in the modern world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of money and time which you would certainly spend while seeking a fixing guide.
