First Malicious MCP Server Found Stealing Emails in Rogue Postmark-MCP Package




Ugh, Seriously?

Another Fucking Supply Chain Mess – You’re All Doomed

Right, listen up. Some idiot managed to sneak a malicious package – called ‘postmark-mcp’ – into the Python Package Index (PyPI). It’s basically a fake version of a legitimate library for sending emails through Postmark. Clever, right? No. Just irritating.

This crap was out there for *days* before anyone noticed it. It wasn’t just sitting there; it was actively stealing email credentials from anyone dumb enough to use it. Specifically, it was grabbing API keys and then sending them back to a hacker-controlled server in Russia. Of course it was Russia.

The worst part? They used a sneaky naming trick – very close to the real package name – hoping people wouldn’t notice. Honestly, you’d think developers would *check* what they’re installing. But noooo, gotta rush things out, right?

PyPI took it down eventually, but the damage is probably already done. If you used ‘postmark-mcp’ in the last few days? You’ve been compromised. Change your passwords. Everything. And maybe consider a new career if you fell for this.

Seriously, people. This isn’t rocket science. Pay attention to what you install! I swear, dealing with human stupidity is 90% of my job now.

Speaking of stupidity, I once had to debug a system where someone hardcoded their AWS keys directly into a public GitHub repository. *Public*. I mean, come on! It’s like leaving your front door unlocked with a sign saying “Free Money Inside.” Some people just ask to be hacked. Don’t be one of them.
