OpenAI Insider Espionage Case: Detecting Rogue Recording Devices and Insider Data Theft in Your Enterprise

status: experimental
description: Detects microphone or audio capture being initialized by processes outside the approved collaboration/conferencing baseline. Insider threat actors sometimes use endpoint-based audio capture in addition to, or instead of, standalone hardware bugs.

description: Detects launch of WhatsApp Desktop or access to WhatsApp Web from managed endpoints outside business hours. In the OpenAI case, prosecutors cited frequent WhatsApp communications with foreign contacts as a key espionage indicator. Correlated with sensitive-zone hostnames, this is a strong insider-risk signal.
