What is Bonsoir QNAP NAS Ransomware
According to recent forum reports, users are dealing with a new ransomware infection known as Bonsoir. This virus targets local networks (NAS, QNAP, Samba/SMB, Synology) encrypting the stored data with AES-CFB algorithms. The decryption of files is thereby offered inside of a text file called HOW-RECOVER-MY-FILES.txt. To elaborate on data encryption, we should mention that Bonsoir applies a one-word extension to each piece of data – .bonsoir. For example, if there was a file named
1.mp4 in your storage, it will change to
1.mp4.bonsoir as a result of infection.

Developers of the virus claim their instructions to be the only solution towards restoring your files. One of the victims actually emptied his pockets and bought the decryption key imposed by extortionists. He, therefore, managed to recover his files with the provided key. Unfortunately, this method does not fit everybody because of the high amounts required by cybercriminals and the risk to be fooled by them. This is why our advice is to delete Bonsoir QNAP NAS Ransomware and try using legitimate utilities to access your data. Also, before we jump over to them, we have to announce an important note: Do not search for keys bought by other victims. This is because each key is often generated individually for specific sets of data. Using a key from another victim may simply corrupt your data and destroy the ability to restore it completely.
How Bonsoir QNAP NAS Ransomware infected your computer
The way ransomware infects data storage servers is not that sophisticated. Usually, this happens when users expose their port to public eyes. This can happen as a result of configuration errors that open port settings to an unprotected network. Then, there might be a window of possibility opened for cybercriminals to start implementing a brute-force attack on your device. After swindlers find a way to scan your port out and log into the system, they eagerly rush towards installing the malicious software. As a result of this, the consequences mentioned above become your worst nightmare, because the precious data is no longer accessible. To prevent further infections like these, you should be careful using such devices yourself. When it comes to local types of networks, it is important to have strong knowledge about security rules. In addition to that, we have to mention that ransomware is commonly distributed via e-mail spam, trojans, botnets, keyloggers, fake software cracking tools, updates, and so forth.
