Audio-Visual Content
Where this stands
No Sigma rule can address this — the telemetry MITRE names has no Sigma logsource behind it.
This happens on infrastructure you do not own, so it never reaches your logs. MITRE's own guidance is internet scanning and threat intelligence, not log analysis.
What the technique is
Adversaries may create or manipulate audio, image, and video content to support targeting and malicious operations. Adversaries may also use synthetic voice recordings, real-time altered audio or video during live interactions, fabricated profile photos and identity documents, or video content depicting fabricated or impersonated individuals. Content may be produced manually through editing tools, generated using AI-assisted tools, or produced using third-party synthetic services. AI-assisted tools have enabled adversaries to produce synthetic media at scale and generate content that is more difficult to identify as inauthentic. Audio-visual content produced through these methods may be used in support of other techniques, such as Phishing, Spearphishing via Service, Phishing for Information, Internal Spearphishing, Social Engineering, Financial Theft, or Establish Accounts.

Much of this takes place outside the visibility of the target organization, making detection difficult for defenders. Detection efforts may be focused on related stages of the adversary lifecycle, such as during Initial Access.
