MALWARE: CLOP

Clop is a ransomware-type virus discovered by Jakub Kroustek. This malware is designed to encrypt data and rename each file by appending the ".Clop" extension. For instance, "sample.jpg" is renamed to "sample.jpg.Clop". Following successful encryption, Clop generates a text file ("ClopReadMe.txt") and places a copy in every existing folder. The text file contains a ransom-demand message.
