Some Idiots Are Scanning the Hell Out of Ports 8530 and 8531 – What Could Possibly Go Wrong?

Well, isn’t this just bloody marvellous? The Interwebs are on fire again because some bright sparks have discovered that Windows Server Update Services (WSUS) might be leaking more than a cheap beer tap — thanks to the shiny new vulnerability CVE-2025-59287. Now, scanners everywhere are hammering ports 8530 and 8531 like they’re giving out free bloody Bitcoin.

The SANS Internet Storm Center noticed a ridiculous spike in probing these ports, which — surprise, surprise — are the default for WSUS over HTTP and HTTPS. So yeah, if you’ve got WSUS hanging open to the big bad internet (and shame on you if you do), expect every script kiddie, ransomware clown, and wannabe hacker to come knocking like it’s Halloween and they’re after your sweet, sweet patches.

The gist? Patch your damn systems, firewall that crap off, and stop letting your WSUS servers moonlight as public buffet tables for every cyber pest. Microsoft’s probably still brewing up the full fix, and meanwhile, the rest of us are sitting here watching scanners dance across these ports like they own the joint. Seriously, I’d rather debug printer drivers blindfolded than watch this circus unfold any longer.

Reminds me of the time a user decided to forward port 80 on their home router “to make Outlook faster.” Three hours later, their NAS was speaking fluent ransomware. Some bastards never learn.
