BlackByte, like other ransomware or crypto-viruses, starts by eavesdropping on the complete system. It detects files where individuals may have saved their credentials and data.
With an innovative algorithm, BlackByte will encrypt the data after scanning.
Files are rendered unreadable by the BlackByte ransomware, which then creates a ransom note (the “BlackByterestorefiles.hta” file) that provides insight on how to approach the hackers for data decryption and other specifics.
Cybersecurity Professional may manually remove harmful files or use antivirus software to do it automatically. Manual virus eradication is suggested just for competent computer individuals. If your computer has been infected with ransomware, you will need a decryption application to regain access to your data. blackbyte ransomware
Blackbyte Malware Harmful Traits

It also explains how to recover encrypted data and how much the decryption application costs.
BlackByte creators, like other ransomware perpetrators, infect machines. These cyber attackers still want to make money by holding their victims hostage.
Blackbyte Ransomware Leverages Proxyshell Faults.
Proxy Shell deficiencies encountered in Microsoft Exchange Servers hackers use who are running and delivering a new ransomware version titled BlackByte. ProxyShell targets several Microsoft Exchange issues.
CVE-2021-34473 pre-auth path confusion flaw bypass access control
CVE-2021-34523 The Exchange PowerShell backend is vulnerable to a privilege escalation issue.
