Seriously? Fake Teams Installers. ARE YOU KIDDING ME?!

Right, listen up, you lot. Some absolute geniuses (read: script kiddies) are pushing malware – they’re calling it “Oyster,” because apparently naming things is hard – through malvertising. Malvertising! Like legitimate advertising wasn’t annoying enough. They’re disguising the damn thing as Microsoft Teams installers, and people are actually downloading them?!

It all starts with dodgy search results leading to websites that *look* like official download pages. Click on one of those, and you get a fake installer packed with this Oyster crap. It’s a multi-stage infection process, meaning it doesn’t just immediately wreck everything; it tries to be sneaky about it first. It drops payloads, steals info, the usual garbage.

The worst part? This isn’t some targeted attack. It’s broad, sloppy, and relies on sheer stupidity. They’re using compromised SEO to get those fake pages ranking high in search results. So basically, if you can’t tell a real website from a pile of digital horse manure, you deserve what you get.

They’ve been seen targeting various countries, including the US and Japan. And it’s all happening on Windows, naturally. Because why bother with anything else? Honestly, I’m starting to think people *want* their systems infected.

Fix it: Don’t download software from random websites! Go directly to Microsoft’s official site. Use a decent antivirus program (though frankly, if you need one for this…), and just generally use your brain before clicking things. Is that too much to ask?

Speaking of idiots… I once had a user call because their computer was “broken” after they downloaded a screensaver promising free puppies. Free. Puppies. It turned out to be a keylogger. A keylogger, for virtual dogs. I swear, some people are actively trying to get hacked.
