Oh, For Fucking Christ’s Sake: Storm-2603 is at it Again

Right, listen up. Some chuckleheads calling themselves “Storm-2603” – original name, I know – are using SharePoint vulnerabilities to shove malware onto systems. Specifically, they’re exploiting flaws in how SharePoint handles files and web apps. They’re deploying a DNS-controlled backdoor, meaning the instructions for what this crap does come from… *the internet*. Like that’s not terrifying enough.

This isn’t some new zero-day discovery; they’re piggybacking on existing weaknesses. And guess who’s getting hit? Companies already compromised by Warlock and LockBit ransomware gangs. So, it’s like kicking a dog when it’s down. They’re using these SharePoint holes to maintain persistence *after* the initial ransom attack. Clever? No. Annoying as hell? Absolutely.

The backdoor lets them steal credentials, move around the network (lateral movement – how original), and generally cause chaos. They’re abusing legitimate SharePoint features like file uploads to hide their malicious code. It’s all very sophisticated… for a bunch of script kiddies with too much time on their hands.

Mitigation? Patch your goddamn SharePoint, use multi-factor authentication (seriously, if you haven’t yet, what are you *waiting* for?), and monitor network traffic. Basic security hygiene, people! It’s not rocket science. But knowing this crowd, half of you will still get owned.

And Another Thing…

I once had to clean up a system where someone uploaded a “funny” screensaver that turned out to be a keylogger. A *screensaver*. People are idiots. This SharePoint mess is just another example of the same stupidity, only on a larger scale. Don’t say I didn’t warn you.
