Makop
CATEGORY:
RANSOMWARE
DESCRIPTION:
Makop ransomware encrypts user’s files and expects a ransom for the decryption key. It uses an AES256 key to decrypt important strings at runtime including a RSA public key. The process creates a mutex to ensure that it avoids infecting the system more than once and uses an entry under the Run key to establish persistence on the host.
