If An Identity was Compromised, Would We Know? by Zoey Chu

This Vectra AI whitepaper warns that identity compromise is increasingly silent and widespread—driven by credential harvesting, token/session replay, abuse of non-human identities (service accounts, API keys, AI agents), and AI-enabled attacker automation—while traditional controls like MFA and EDR often fail to reveal abuse; it advocates treating identities as behavioral entities, correlating identity, network, and cloud signals, and assuming compromise to prioritize detection of attackers already inside.
