This rule aims to detect potential Emotet malware delivery through the use of padded .doc files compressed within small zip files. The detection logic works by inspecting inbound attachments to identify zip files that meet specific criteria: they must contain .doc files, have a size less than 1MB, and an uncompressed size exceeding 500MB. Additionally, the sender's profile is evaluated for newness or outlier status, or if there's a history of malicious or spam messages without false positives. This approach focuses on identifying patterns associated with the Emotet threat actor, particularly their tactics of using large padded documents to evade initial detection mechanisms.
