Description
Detects messages where the sender and recipient are the same address, containing external links and classified as credential theft by NLU analysis. The rule identifies self-sent messages from non-free email providers that pass DMARC authentication but contain 1-4 links to external domains, with machine learning classification indicating credential theft intent.
