Xygeni GitHub Action Compromised Via Tag Poison

Another Fucking Supply Chain Shitshow

Oh for fuck’s sake. Just when you thought the day couldn’t get any more irritating, some wanker at a “security” company has gone and proven that irony isn’t just dead, it’s been beaten with a length of CAT5 cable and buried in the server room next to that intern who asked me why the coffee machine wasn’t working during a power outage.

Xygeni – yes, that’s a security outfit, the kind that charges you an arm and a leg to tell you how to not get breached – has only gone and gotten their own GitHub Action compromised via tag poisoning. That’s right, the very fuckwits who are supposed to stop this shit happening have become the poster children for “do as I say, not as I do, you incompetent morons.”

Here’s what happened, since you’re obviously too busy reading Reddit to understand basic supply chain hygiene: some miscreant figured out that Xygeni were using floating tags on their GitHub Action (because apparently pinning to specific commit SHAs is too much like hard work for these security “experts”). They moved the version tags to point at malicious commits instead of the legitimate code. So when CI/CD pipelines pulled down what they thought was the latest “secure” version of Xygeni’s action, they got a nice little turd sandwich of credential-stealing malware instead.

The absolute brass fucking neck of it. A company selling security solutions can’t even secure their own bloody distribution mechanism. It’s like a condom manufacturer distributing products with pinholes pre-installed. You’ve got developers everywhere pulling this action into their pipelines, trusting these muppets with their build processes, and Xygeni couldn’t even be arsed to implement basic immutability on their release tags. I swear, if stupidity were electricity, these clowns would be a goddamn power station.

And before you start whinging about how “sophisticated” this attack was – it wasn’t. Tag poisoning is Script Kiddie 101 shit. It’s the digital equivalent of changing the price tags in a supermarket. If your supply chain security strategy can be defeated by a bored teenager with a GitHub account and five minutes to spare, you deserve everything that’s coming to you, including the 3 AM phone calls from your CISO having a coronary.

So now you’ve got thousands of repositories potentially leaking secrets, credentials, and whatever other sensitive shit you’ve been pumping through your CI/CD pipelines, all because someone couldn’t be bothered to use proper version pinning. Hope your weekend on-call rotation is ready for this clusterfuck, because someone’s going to have to explain to the board why the build server is mining cryptocurrency and emailing your AWS keys to North Korea.

Reminds me of the time I caught a user trying to “secure” their password by writing it on a Post-It note and sticking it to the bottom of their keyboard. At least that pillock was only compromising one account, not half the fucking internet. You lot make me sick.
