BEC tools: The 3 techniques most commonly used in BEC attacks

Business Email Compromise (BEC) remains a significant threat to organizations, exploiting trust and business process gaps through social engineering rather than malware. BEC attacks employ techniques like domain spoofing, thread hijacking, and credential theft, often enhanced by automation and AI to appear legitimate within standard communication workflows. Traditional detection systems struggle because BEC emails lack malicious payloads, relying instead on impersonation and clean language to bypass static filters. Effective defense requires adaptive detection systems, such as Sublime's platform, which uses behavioral analysis and explainable AI to identify anomalies in communication patterns. This approach is complemented by identity controls, multi-factor authentication, and real-time monitoring to mitigate risks. The article emphasizes the importance of understanding normal communication behavior, implementing layered defenses, and maintaining robust business process controls to prevent unauthorized actions and financial fraud.
