- Engineer — Plan: AitM phishing bypasses authenticator-app MFA; audit whether high-value Microsoft accounts have phishing-resistant (FIDO2) MFA enabled and review Conditional Access token-binding policies to reduce session-hijack risk.
- SOC/IR — Plan: The AitM-against-M365 technique warrants tuning detections for anomalous OAuth token issuances and Conditional Access bypass patterns; build a hunt targeting users in AI/policy roles for suspicious sign-in behavior since no IOCs were published.
- Leader — Learn: China-nexus espionage group targeting AI policy think tanks, universities, and legal firms is useful sector-awareness context; no immediate action unless your organization operates in AI policy research or adjacent legal advisory work.
- Engineer — Plan: AiTM and device-code phishing bypass standard MFA; audit your M365 conditional access policies to restrict or block device code flow, and prioritize phishing-resistant MFA (FIDO2 or certificate-based) for privileged accounts this quarter.
- SOC/IR — Plan: Build or tune detections for suspicious device-code OAuth grant flows and anomalous session token reuse in Entra ID / M365 audit logs — the AiTM component means valid MFA completion is not a reliable innocence signal.
- Leader — Learn: Confirms that commodity phishing platforms are now routing around standard MFA at scale; useful background when justifying a phishing-resistant MFA upgrade on the roadmap or fielding customer security questionnaires about M365 identity controls.
