Ransomware Chaos: Microsoft SharePoint Under Siege by Storm-2603!
Ransomware enters the Microsoft SharePoint exploitation ring, with Storm-2603 and other Chinese-backed crews causing havoc. Over 400 organizations have been hit, including the US Energy Department. Microsoft urges immediate security updates. A comedy of cyber errors, where the only punchline is your data disappearing.

Hot Take:
And just when you thought your SharePoint was safe, Storm-2603 comes waltzing in with a ransomware buffet that’s got more flavors than a Chinese takeout menu. Microsoft’s latest adventures in patching vulnerabilities make me wonder if their update team is staffed by squirrels on espresso. Just remember, when it comes to cybersecurity, always expect the unexpected—especially if it’s sneaking through your SharePoint server faster than you can say “unauthenticated remote code execution!”
Key Points:
– Storm-2603 is the newest threat group exploiting Microsoft SharePoint vulnerabilities.
– The group is using Warlock and Lockbit ransomware on compromised systems.
– Vulnerabilities exploited include CVE-2025-49704 and CVE-2025-49706.
– Over 400 organizations have reportedly been affected.
– Microsoft has released patches, but the threat persists, especially for unpatched systems.
