Seriously, Another One.

Right, listen up you lot. Some clowns – and I use that term generously – have been exploiting a zero-day in Sitecore, the content management system favored by people who apparently enjoy making life difficult for security teams. A vulnerability in Sitecore’s Experience Editor allowed these… *individuals* to inject malicious code via crafted requests. What does that mean? Backdoors. Lovely, persistent backdoors. They’re deploying webshells and who knows what else.

The attacks started around December 20th, 2023, and are still ongoing as of this writing. Affected versions include Sitecore XP (10.2 & 10.3) and Sitecore XC (10.0). If you’re running any of those, consider yourself warned – patch *immediately* unless you enjoy uninvited guests poking around your systems. They’ve been observed using tools like Ncat to establish reverse shells. Ncat! Like we needed another reason to hate network utilities.

Mandiant and Microsoft are all over it, releasing detection guidance (because patching is apparently optional for some people). The root cause? A deserialization flaw in the Experience Editor. Honestly, *deserialization flaws*. In 2024. It’s pathetic. They’re blaming a third-party component, naturally. Always someone else’s fault.

So yeah, Sitecore is compromised. Backdoors are being installed. Update your damn systems before you end up needing to rebuild everything from scratch. Don’t come crying to me when your data gets ransomed. I have better things to do than listen to your whining.

And another thing…

I once had to deal with a system admin who refused to patch a server because “it was working fine.” Three days later, it was part of a botnet launching DDoS attacks. Three days! You know what I did? I remotely locked his account and told him to read the security advisories. Serves him right. Honestly, some people just *want* to get hacked.
