JB88 Ransomware

The infosec experts who first detected the JB88 Ransomware determined that it is not an entirely new ransomware threat. Instead, it can be categorized as being part of the Matrix Ransomware family. Being based on a previously released malware doesn't diminish the JB88 Ransomware's potency in the slightest, though. Suppose the JB88 Ransomware manages to infiltrate a computer successfully. In that case, it will proceed to encrypt the stored files by using a combination of two strong encryption algorithms - AES-256 and RSA-2048, to ensure that the locked files cannot be restored by brute-forcing the decryption key.

The JB88 Ransomware follows a complex pattern for the names it assigns to every encrypted file. First, it appends an email address that belongs to the hackers - Jonbrown88@criptext.com, in this case, then a random string that is created for the current victim specifically, and finally appends '.JB88' as a new extension. The ransom note with instructions is placed in every folder containing locked data, as a file named 'JB88_README.rtf.' Apparently, the criminals have three different email addresses and they want victims to send an email to ALL of them. They also allow up to 3 small files to be attached, which will be decrypted for free. The email addresses are:

• Jonbrown88@criptext.com
• Jonbrown88@aol.com
• Jonbrown88@tutanota.com

The ransom note doesn't mention what the sum demanded by the criminals in exchanged for the decryption key is going to be or if any cryptocurrency is going to be used.

While it may be stressful to lose access to your files or even more so if business-related data gets locked suddenly, it is recommended to stay calm and avoid following the criminals' demands.
