Core (Makop) Ransomware Overview

Core ransomware belongs to the Makop ransomware family and operates as a file-locking crypto virus that encrypts a victim’s files, making them inaccessible. After encrypting files, it modifies filenames by appending a unique victim ID, the attackers’ email address, and the “.core” extension. It then delivers a ransom note in the form of a text file titled “+README-WARNING+.txt”, warning the victim against unauthorized decryption attempts.

Below is a summary table highlighting the most crucial details of the Core (Makop) ransomware threat:
