Signs that you are dealing with a CrypBoss infection

CrypBoss is a type of ransomware security expert state is part of the same malware family as HydraCrypt and UmbreCrypt. Consequentially, the primary method of distribution is via the Angler exploit kit, which is well-known to invisibly direct the browser to a malicious website that identifies and uses security vulnerabilities to enter your system.
Once the malware enters your system, they begin to upload and execute additional software and delete the shadow copies of the encrypted files. Consequentially, unless you have backups stored in other locations other than your computer, you cannot restore the infected files.
