Booking.com Phishing Campaign Detection
This rule detects various indicators associated with the Booking.com phishing campaign targeting hotels and customers. It identifies suspicious web requests to non-Booking.com domains containing 'op_token' and 'complaint' or 'reservation' keywords, especially when combined with punycode, 'booklng' typos, or management-related subdomains. It also looks for partner kit patterns involving 'sign-in/?tpo_token=' and 'booklng' in URLs. Additionally, it identifies suspicious emails from newly generated Gmail accounts with specific subjects ('Automatic reply', 'Availability', 'Reservation') containing 'op_token' in the subject or body.
