Defending against deepfake social engineering

Deepfakes bring synthetic voice and video into social engineering. Attackers can impersonate an executive on a call or in a short video clip, lending manipulated requests a level of credibility that text cannot. High-profile incidents have already shown finance teams authorizing large transfers after a convincing deepfake call.

Why traditional controls fall short

Most awareness programs never test synthetic-media scenarios, so employees meet their first deepfake during a real attack. And because the media is convincing by design, telling people to 'look for signs of a fake' is unreliable guidance.

A practical approach

Shift the defense from detection to process. Require out-of-band confirmation for sensitive actions regardless of who appears to be asking, establish verification codewords for executives, and rehearse these steps. Then validate that the process holds under pressure by running authorized simulations that include voice-based pretexts.

Vyvern helps teams put that rehearsal in place — running approved, realistic social engineering across voice and other channels, and routing anyone who slips into training matched to what fooled them.
