IFF Assessment
This tactic demonstrates an escalation in social engineering sophistication by a known threat actor, increasing the difficulty for defenders to detect and prevent attacks.
Defender Context
Defenders need to be aware of evolving social engineering tactics that leverage AI and deepfake technology. Training employees to be highly skeptical of unexpected video calls and verifying identities through out-of-band channels is crucial. This trend highlights the growing need for advanced threat detection that can identify manipulated media and unusual communication patterns.
