Threats:

Medusa is a ransomware malware family targeting businesses and institutions. Medusa encrypts crucial data, rendering it inaccessible, and attempts to pressure users to pay to regain control of their information. The group behind this malicious software hosts a TOR website where it shares the list of the organizations whose infrastructure has been compromised. This malware utilizes various tactics, including exploiting vulnerabilities and employs a unique file extension (".MEDUSA") to mark encrypted files.
