Secure enterprise sharing with access reviews for Microsoft 365
Medium · BleepingComputer ·
What happened
Vendor-sponsored BleepingComputer article (tenfold Software) notes that Microsoft 365 file sharing often leaves stale access, with little visibility into who can still reach sensitive data. No CVE or breach; no specific victims named.
What to do now
Review M365 sharing links and stale guest/external accounts now: audit SharePoint/OneDrive/Teams permissions, disable anonymous and company-wide links, set link expiration, and run recurring owner-driven access reviews. Verify vendor claims against Microsoft docs.
