CrowdStrike provides an in-depth analysis of the Samsam ransomware, detailing its infection process, propagation, and anti-forensic capabilities, which complicate the recovery of encrypted payloads. Samsam employs various delivery methods, including credential gathering and unique RSA public key generation for each user, necessitating individual ransom payments. The ransomware uses tools like Mimikatz and Sysinternals utilities for propagation and cleanup, with the payload being encrypted and loaded in memory, making forensic recovery difficult. Despite these complexities, CrowdStrike Falcon Prevent can detect and stop Samsam before file encryption occurs, leveraging behavioral patterns and machine learning algorithms. The analysis highlights different variants of Samsam, including those that run entirely in memory, and describes the meticulous process of file encryption, resource extraction, and cleanup. CrowdStrike's solutions are designed to prevent Samsam's execution, showcasing their advanced threat detection and response capabilities.
