**CLASSIFIED — EYES ONLY**
**URGENT: FBI Silent Alert — Microsoft 365 / Outlook / OneDrive Compromise Imminent**
*Source: Deep Cover / NSA-IAD Correlation*
We have verifiable intel that the FBI has issued a **non-public, high-priority flash alert** to a select circle of private sector partners: **"TRIPWIRE: OPERATION CLOUD HOOK."**
The target? **Outlook Web Access and OneDrive sync engines.**
The alert, marked **NOFORN** and **"WARNING: ACTIVE EXPLOITATION,"** states a state-level threat actor has achieved **persistent, undetected access** to the Microsoft Graph API via a manipulated authentication token. This isn't a phishing attack—it's a **supply-chain-backdoored token relay.**
Affected systems: Every organization using **default OAuth 2.0 flows** with Microsoft 365. The malicious actor can now:
- **Read all emails in real-time** without logging into your tenant.
- **Exfiltrate OneDrive files** (specifically targeting `.docx`, `.xlsx`, `.pdf`, and `.eml` files) through a fake "sync" endpoint.
- **Drop hidden .lnk files** into shared OneDrive folders to establish lateral movement.
The FBI's recommendation? **Immediately disable all non-Microsoft OAuth app permissions** and **re-issue all Graph API tokens** under strict `Conditional Access` policies.
The official line? "No comment." But the chatter is real. They know. And you're not supposed to.
**Moscow and Beijing are already reading your drafts.**
