A SOC analyst starts a shift by opening an alert queue where an AI triage tool has already scored a suspected executive video request. The score signals risk. It does not settle whether the request is genuine, whether a payment can proceed, or who owns the decision. In this lesson, we will frame the work product for a suspected deepfake event: a defensible fraud and security disposition supported by evidence, verification, and a clear escalation path.
Deepfake means audio, video, or imagery created or altered with machine learning to imitate a person. Fraudsters use this material to exploit trust in a familiar voice or face, often while adding urgency and secrecy. Executive impersonation aligns with MITRE ATT&CK technique T1656 Impersonation. The security team’s job is to protect the decision point, not to decide whether media merely looks authentic.
Simulated incident: Northbridge Credit Union receives a video request that appears to come from its chief financial officer and asks for an urgent wire transfer. We will trace how the team turns that request into a recorded, reviewable outcome. Let’s follow the path from intake through escalation:
A defensible disposition explains what happened, what evidence was preserved, who had authority to decide, and why the team acted or paused. It does not require proving that media is synthetic before stopping a risky transaction. For a high-value request, independent verification and the existing payment approval process provide stronger assurance than visual or audio cues alone.
The case record should separate observed facts from assumptions. A ticket, call record, and wire draft establish the request, channel, timing, and potential impact. They do not establish that the caller was the CFO. This distinction protects the case from a familiar failure mode: treating a convincing presentation as identity proof. Review the evidence Northbridge has at intake:
