Win32/VB.NXB detection is a virus detection you can spectate in your system. It generally shows up after the provoking actions on your PC – opening the suspicious e-mail, clicking the advertisement in the Web or setting up the program from unreliable resources. From the moment it appears, you have a short time to act until it starts its harmful activity. And be sure – it is much better not to await these harmful actions.

What is Win32/VB.NXB virus?

Win32/VB.NXB is ransomware-type malware. It looks for the documents on your disk drives, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this virus also does a ton of damage to your system. It changes the networking setups in order to prevent you from looking for the elimination tutorials or downloading the antivirus. Sometimes, Win32/VB.NXB can additionally block the setup of anti-malware programs.

Win32/VB.NXB Summary

Summarizingly, Win32/VB.NXB virus activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Uses Windows utilities for basic functionality;
  • CAPE extracted potentially suspicious content;
  • 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;
  • Uses Windows utilities to create a scheduled task;
  • Deletes executed files from disk;
  • Yara detections observed in process dumps, payloads or dropped files;
  • Ciphering the files kept on the victim’s drives — so the victim cannot open these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a major problem for the last 4 years. It is challenging to realize a more dangerous virus for both individual users and businesses. The algorithms used in Win32/VB.NXB (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 currently exists, and possibly will exist. However, that virus does not do all these bad things immediately – it can take up to several hours to cipher all of your documents. Therefore, seeing the Win32/VB.NXB detection is a clear signal that you have to start the elimination procedure.

Where did I get the Win32/VB.NXB?

Common methods of Win32/VB.NXB spreading are usual for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern strategy in malware distribution – you receive the email that imitates some routine notifications about deliveries or bank service conditions modifications. Within the e-mail, there is a corrupted 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.

Avoiding it looks quite uncomplicated, but still demands tons of recognition. Malware can hide in various places, and it is better to prevent it even before it invades your PC than to depend on an anti-malware program. General cybersecurity awareness is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a great deal of time and money which you would spend while seeking a solution.
