#StopRansomware: SafePay Ransomware
Advisory at a Glance Title #StopRansomware: SafePay Ransomware Original Publication  October 20, 2026 Executive Summary This advisory details recent activity by the SafePay ransomware group. SafePay actors have been highly active since August 2024, targeting businesses and critical infrastructure across North America, South America, Europe, and Australia. SafePay actors typically gain access to networks by stealing or guessing passwords, exploiting vulnerabilities in security systems, and using phishing tactics.  Once inside the network, SafePay actors establish control by creating new accounts or taking over existing ones. They then use legitimate system tools to move through the network, identify valuable files, and disable security protections to avoid detection. Following, they encrypt the victim’s files, making them inaccessible, and leave a ransom note demanding payment in cryptocurrency. This advisory urges organizations to follow recommended security measures to reduce the risk and impact of SafePay ransomware attacks.
