Microsoft Teams: Now Featuring Malware, Because Of Fucking Course It Does

Alright, listen up. The latest clown show comes courtesy of some threat actor who figured out that Microsoft Teams — yes, that productivity dumpster fire — is a perfect delivery system for malware. Because users trust Teams about as much as they trust email from HR, which is to say: blindly and stupidly.

The assholes abuse external Teams access to chat up employees, pretend to be someone vaguely legit, and then drop a malicious file like it’s just another boring work document. Open it, and boom — you’ve just invited the SNOW malware into your network. Surprise! It’s not a fucking snow day.

SNOW is a shiny new malware loader whose whole job is to quietly screw you over. Once it’s in, it phones home, waits for orders, and pulls down whatever additional shit the attackers want — info stealers, remote access tools, persistence crap, you name it. It’s basically a digital parasite riding in on Microsoft’s “trusted collaboration” bullshit.

The real kicker? This works because Microsoft Teams is often wide open to external users, and nobody bothers locking it down. Users see a Teams message, assume it’s safe, and click like trained lab monkeys. Security controls? User awareness? Ha. Fucking adorable.

So yeah, if your org lets randos message employees on Teams and send files, congratulations — you’ve built a malware drive-thru. At least email phishing had the decency to feel sketchy. This shit wears a corporate badge and smiles while it stabs you.

Anecdote time: years ago, I told a company to disable external chat and got told it would “hurt collaboration.” Two weeks later they got popped by malware delivered through — wait for it — a chat app. They asked if I could help clean it up. I laughed, finished my coffee, and asked if they’d learned a fucking lesson.
