How does Spambrella detect BEC attacks that contain no links or attachments?

BEC attacks are particularly dangerous precisely because they carry none of the traditional threat indicators – no malicious links, no infected attachments, no known-bad sender domains. Spambrella’s anti-impersonation engine detects BEC through: display name analysis (identifying when a message claims to be from a known executive but originates externally), lookalike domain detection (catching subtle variations such as “rn” substituted for “m”), header authentication analysis (SPF, DKIM, DMARC cross-referencing), and anomalous communication pattern detection. Suspicious messages are tagged, quarantined, or flagged depending on configured policy.
