Znsm Ransomware – Remove and Decrypt *.Znsm Virus Files

What is Znsm Ransomware?

Znsm ransomware is a notorious computer malware. It is a file-encrypting virus that locks all your files making them completely useless. This new threat is a variant of the STOP/DJVU Ransomware group. This group has been active for years and regularly releases new malware variants with different names.

Znsm File Virus is designed to exploit vulnerabilities on the targeted PC, encrypt files, and demand ransom money through BitCoins for the decryption tools. It also renames the encrypted files by adding the “.znsm” extension as a suffix to the original filenames. For instance, if a file named “picture.jpg” will get renamed as “picture.jpg.znsm” after it gets encrypted.

Znsm Ransomware

You will have no access to those encrypted files. According to Znsm ransomware, you can only restore your data by paying ransom money. You will find a ransom note “_readme.txt” on your computer demanding $980 for the decryption key. However, it also mentions that if you make contact with hackers within 72 hours then you will get a 50% discount.

Ransom Note

As most people keep important documents, images, videos, audio, or work files stored on their PC, hackers know that they can extort money from them. However, most ransomware victims get cheated and don’t get their data back even after paying the money. So we recommend you do not make any contact with attackers and remove this threat immediately.

How does it work?

Znsm Ransomware is a computer virus that takes files hostage on the infected PC until a certain ransom is paid by the victims. It uses a highly sophisticated encryption algorithm to render your files useless. It demands ransom payments in Bitcoin which is a cryptocurrency and cannot be tracked. So once you made the payment, you will never know who received it. Operators behind this threat promise to give you a decryptor after they get paid.

This threat uses two methods to encrypt data on the system. If your computer is not connected to the Internet then it will use an offline encryption key. It can be identified by the Personal ID assigned to victims which you can find in the ransom note “_readme.txt”.

If your ID ends with t1 then it is an offline encryption. It means if someone with offline encryption pays the ransomware attackers and buys the decryption key, they can share it with others. There is a free Emsisoft STOP Djvu Decryptor that compiles the offline keys and offers free decryption of files.

But if your PC was connected to the Internet when Znsm Ransomware hit your computer then it generates the online key. Which means there is no way to decrypt such files. You will not find any free decryptor for such versions anywhere. If your personal ID does not end with the t1 then it’s online encryption.

How it infects your PC?

Znsm Ransomware is a crooked malware infection that could easily attack any Windows OS. There are various ways through which your computer can get infected by such threats. It is extremely hard to pinpoint the exact way but in most cases, bundled freeware applications deserve the blame.
