BlackByte, like any other ransomware or crypto virus, starts by listening to the entire system. Identifies files where individuals save their credentials and data.
BlackByte encrypts data after scanning with an innovative algorithm.
Files are made unreadable by BlackByte ransomware, which creates a payment note (“BlackByterestorefiles.hta file”) that provides information on how to contact hackers for data encryption (AES Encryption) and other features.

And then leave a note titled “BlackNote Files” and “BlackByterestore” including the ransom note and the attacker’s instructions.
It also explains how to retrieve encrypted data and how much the decryption application costs.

BlackByte creators, like other ransomware killers, influence machines. These cyber attacks still want to make money by holding their victims hostage.

Blackbyte ransomware affects proxy shell errors.

Proxy shell errors found on Microsoft Exchange servers are used by hackers to launch and distribute a newer version of ransomware called BlackByte. ProxyShell has a number of issues with Microsoft Exchange.
CVE-2021-34473 Confusion error before crossing access control
CVE-2021-34523 Exchange PowerShell Server Privilege Escalation Issue.
