JosepCrypt is a crypto-virus that encrypts files on the target PC and demands ransom to be paid by the victim to free the files. It may attack any sort of window’s OS like Vista, Windows 7, Win 8 and Win 10. Once installed, this Ransomware uses strong encryption algorithm combination of RSA-2048 key and AES CBC 256-bit. This means files are locked with public and private key. Thus users are left with no option except to pay the ransom and get their fiels back. JosepCrypt may drop malicious payloads and entries in the windows’s registry to auto-launch its program. It searches for various important files like Documents, PDF, photos, music, videos, databases, etc to encrypt them. After encrypting the files, the ransomware changes the desktop wallpaper to ransom note:
