China’s Stormy SharePoint Shenanigans: Microsoft Warns of Vulnerable Servers Under Siege
Microsoft linked SharePoint exploits to China-nexus groups Linen Typhoon, Violet Typhoon, and Storm-2603. These actors bypassed authentication and stole cryptographic keys from vulnerable servers. Microsoft urges immediate patching due to potential widespread adoption of these exploits.
Hot Take:
It’s a stormy forecast for SharePoint users! Microsoft has blown the whistle on a trio of China-linked cyber weather systems—Linen Typhoon, Violet Typhoon, and Storm-2603—who have been dancing through SharePoint flaws like they’re auditioning for the next big meteorological disaster movie. Time to batten down the hatches, folks, or at least patch those servers!
Key Points:
- Microsoft identified China-linked groups exploiting SharePoint flaws since July 7, 2025.
- Threat actors Linen Typhoon, Violet Typhoon, and Storm-2603 are involved.
- Exploits target internet-facing SharePoint servers, stealing cryptographic keys.
- Microsoft recommends immediate patching and mitigation to protect systems.
- SentinelOne researchers identified attack clusters but didn’t assign specific actors.
