This new ransomware was discovered by Michael Gillespie on 8 February 2019 and it is still improving over time. This blog will explain the technical details and share information about how this new ransomware family is working. There are some variants of the Clop ransomware but in this report, we will focus on the main version and highlight part of those variations. The main goal of Clop is to encrypt all files in an enterprise and request a payment to receive a decryptor to decrypt all the affected files. To achieve this, we observed some new techniques being used by the author that we have not seen before. Clearly over the last few months we have seen more innovative techniques appearing in ransomware.
