What is Nbzi Ransomware

Nbzi Ransomware is a type of malware that belongs to the Djvu family. Its primary purpose is to encrypt files on the victim’s computer, rendering them inaccessible. The ransomware appends the .nbzi extension to the filenames of the encrypted files. For example, a file named 1.jpg would be renamed to 1.jpg.nbzi. It uses a strong encryption algorithm, and each victim’s files are encrypted with a unique key. The ransomware uses the Salsa20 encryption algorithm. If Nbzi cannot establish a connection to the attacker’s server before starting the encryption process, it uses an offline key, which is the same for all victims. After encrypting the files, Nbzi Ransomware creates a _readme.txt file containing a ransom note. This note informs the victim that all their files have been encrypted and that the only way to recover them is to pay a ransom. The ransom amount typically ranges from $490 to $980.

Decrypting .nbzi files can be challenging due to the strong encryption used by the ransomware. If the ransomware used an offline key, tools like the Emsisoft Stop Djvu Decryptor may be able to decrypt the files. However, if an online key was used, decryption is significantly more difficult and may not be possible without the specific key. In case of infection, it’s recommended to remove the ransomware from the system first, using a reputable antivirus or antimalware tool. After removal, victims can attempt to restore their files from backups if they have them. If no backups are available, victims can try using a decryption tool or seek help from a professional data recovery service. It’s important to note that paying the ransom is not recommended, as it does not guarantee the recovery of the files and encourages the attackers to continue their illegal activities.

How Nbzi Ransomware infects computers

Nbzi Ransomware typically infects computers through malicious advertisements, downloads from peer-to-peer (P2P) networks, torrent websites, third-party downloaders, and similar avenues. Neglecting to update software also exposes computers to the risk of infection. In some cases, threat actors may use information stealers like Vidar or RedLine to harvest data before encrypting files.

Nbzi Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Nbzi Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers.
