Alcatraz Ransomware Detection

This YARA rule detects the Alcatraz ransomware by identifying specific byte patterns associated with its file encryption routines and its communication with remote servers. The rule looks for three distinct byte sequences: one related to file encryption logic ($encrypt_files) and two others related to remote server communication ($remote_server and $remote_server_2). All three patterns must be present in a file that also starts with the MZ header (0x5A4D) to trigger a detection.
