CryptNet is a ransomware-as-a-service (RaaS) which has been advertised on underground forums since early 2023.
The ransomware is programmed in the .NET programming language and 256-bit AES and 2048-bit RSA encryption are used to lock files.
The malware uses .NET Reactor for obfuscation and deletes shadow copies and the backup catalog to inhibit recovery.
