The Play ransomware group has been active since June 2022, targeting businesses and critical infrastructure in North America, South America, and Europe. They gain access by exploiting vulnerabilities, using stolen credentials, and leveraging remote access services. Their attacks follow a double extortion model, encrypting systems after exfiltrating data using AES-RSA hybrid encryption.
