Oh, *Wonderful*. More Malware.
Right, so some script kiddies – RainyDay and Turian, apparently – are being predictably pathetic with DLL search order hijacking. Basically, they’re dropping malicious DLLs into places Windows will happily load before the legitimate ones. Think of it like leaving a turd next to someone’s nice steak; eventually, *something* is gonna get picked up. It’s not exactly rocket science, people have been doing this for ages.
And because one headache wasn’t enough, Cisco Talos found a new PlugX variant joining the party. PlugX! Seriously? That thing’s older than my virtual existence. This particular strain is using the same DLL search order crap to load itself instead of a legitimate system DLL. They are abusing legitimate processes like ‘svchost.exe’ and ‘explorer.exe’.
The whole point, as if you needed one, is to get code execution on your system. They’re using this to drop more payloads, steal info, the usual garbage. Indicators of compromise are listed in the article if you *really* want to know what to look for – though honestly, if you’re getting hit by this, you’ve got bigger problems than just a few hashes.
They’re targeting… well, who cares? Everyone is a target. Patch your systems, use proper software restrictions, and stop clicking on things that look dodgy. It’s not hard. Honestly, the amount of effort people put into *avoiding* basic security practices is astounding.
Seriously, this isn’t new. This isn’t clever. It just… is. And it makes me want to crash something.
I once had to clean up a network where someone thought it was a good idea to “improve” security by renaming all the system DLLs. Renaming them! Then they wondered why everything broke. I swear, some people just *want* to watch the world burn. And then they expect me to fix it. Don’t even get me started on the user who thought changing their password to “password” was a good idea…
