What is NSIS:BackdoorX-gen [Trj] virus?

NSIS:BackdoorX-gen [Trj] is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware also does a lot of damage to your system. It changes the networking settings in order to stop you from checking out the elimination manuals or downloading the anti-malware program. In some cases, NSIS:BackdoorX-gen [Trj] can even block the launching of anti-malware programs.

NSIS:BackdoorX-gen [Trj] Summary

In total, NSIS:BackdoorX-gen [Trj] ransomware activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the documents kept on the target’s disk — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a headache for the last 4 years. It is hard to imagine a more harmful malware for both individual users and companies. The algorithms used in NSIS:BackdoorX-gen [Trj] (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these bad things instantly – it can take up to several hours to cipher all of your documents. Thus, seeing the NSIS:BackdoorX-gen [Trj] detection is a clear signal that you have to start the removal process.

Where did I get the NSIS:BackdoorX-gen [Trj]?

General tactics of NSIS:BackdoorX-gen [Trj] distribution are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively modern method in malware spreading – you receive the email that mimics some normal notifications about shippings or bank service conditions changes. Inside of the email, there is a malicious MS Office file, or a 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 uncomplicated, however, still requires a lot of attention. Malware can hide in various places, and it is far better to stop it even before it invades your PC than to rely upon an anti-malware program. Standard cybersecurity knowledge is just an essential item in the modern world, even if your interaction 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 fix guide.
