Hackers Abuse Marimo, Hugging Face, and Common Sense
Alright, gather round children, it’s time for another episode of “Why You Can’t Have Nice Things”. Some bright spark hackers found a lovely little flaw in Marimo (that cute Python notebook thing everyone blindly trusts) and used it to shove the NKAbuse malware down people’s throats. Because of course they fucking did.
The trick? Abuse Marimo’s handling of notebooks so it happily runs attacker-controlled code. That code then pulls in a malicious package hosted on Hugging Face — yes, that Hugging Face, the one everyone assumes is full of rainbows and ethical AI unicorns. Surprise! It’s also a great place to stash malware if nobody’s bloody looking.
Once this shitshow kicks off, NKAbuse gets installed and your machine is now part of a criminal clown car. The malware turns systems into proxy nodes for shady traffic, helps with DDoS attacks, and can even run cryptominers. So your CPU is sweating its balls off while some asshole gets richer and you get nothing but a higher power bill.
The best part? None of this needs some elite nation-state hacking voodoo. It’s just developers running notebooks, trusting packages, and not bothering to check what the fuck they’re executing. “But it was from Hugging Face!” Yeah, and I once trusted a user to reboot a server without fucking it up. Learn from my pain.
Moral of the story: if your workflow involves auto-running notebooks and pulling random dependencies from the internet, congratulations — you’re doing the attacker’s job for them. Lock your shit down, audit your code, and stop assuming platforms are magically safe because they’re popular.
I’ll leave you with a fond memory: years ago, a developer told me “it’s fine, it’s just a script.” Five minutes later the network was on fire and he was on LinkedIn looking for a new job. Same energy here.
