BEC/Fraud: B2B sales inquiry cold outreach lure

Description

Detects inbound plain-text messages that mimic sales inquiries or project discussion requests, using language referencing sales teams, project requirements, and procurement officers to establish false business legitimacy. An NLU classifier confirms the message content aligns with B2B cold outreach or purchase order themes, a common pretext used to initiate contact before pivoting to fraudulent business proposals or follow-on scams.
