ImageSource CTB LOCKER (Curve-Tor-Bitcoin Locker) also known by Critroni is an example of file encrypting malware infections. The ransomware was released middle of July 2014 targeting windows OS. Curve - comes from its persistent cryptography based on elliptic curves, which encrypts the affected files with a unique RSA key. Tor - comes from the malicious server placed in onion-domain which is very difficult to take down. BitCoin- refers to the possibility to pay in BitCoins, avoiding normal payment systems that can lead back to attackers.  **CTB-Locker is a ransomware variant that first encrypts the files, then claims you have 4 days (96 hours) to make the payment, and if the victim doesn't send money in time, their files gets permanently encrypted.

ImageSource JIGSAW RANSOMWARE This ransomware was first spotted in April 2016. A notorious virus that disables the computer and encrypts the files on it and threatens to delete them, is actually the first one that carries out this threat. Once the virus invades the system a countdown timer starts and if the demanded ransom of $150 is not paid within first hour it deletes one file and continues deleting as the timer resets every 60 minutes deleting more and more files. JIGSAW virus encrypts files using AES-128-CBC and creates a secret decryption key, which is needed to decrypt all these encrypted files. Jigsaw malware creates a number of problems:- Jigsaw drops other type of infections in order to invade your system deeply. Spam files and registries are injected on to your device. A lot of pop-up ads come out on the screen. Slows down system’s performance.
