- Use Static analysis for GHA to catch security issues: https://github.com/zizmorcore/zizmor - set locally: pnpm config set minimum-release-age 4320 # 3 days in minutes https://pnpm.io/supply-chain-security for other package managers check: https://gist.github.com/mcollina/b294a6c39ee700d24073c0e5a4e... - add Socket Free Firewall when installing npm packages on CI https://docs.socket.dev/docs/socket-firewall-free#git…

The only way to 'harden your github actions' is to not use github actions.

Earlier quoted context omitted.

You also need to make sure you take care using PR titles and descriptions in your GHA because if they contain `text` it *may be executed lmfao. edited: not "will", may depending on your GHA

Can you cite this? It's not YAML execution syntax, surely Github doesn't do it, the only vector I can see is if you put it unquoted into a shell script inside of a GHA yaml.

I think he means template-injection -- https://woodruffw.github.io/zizmor/audits/#template-injectio...

This is bad. If they came out announcing this, without a long winded explanation and further details, it's because they're staring at a bottomless pit and they haven't put the lid on it yet.

For a Fortune 100, to go out of your way to spook investors is the least desirable approach.

GitHub: "We are investigating unauthorized access to GitHub’s internal repositories. While we currently have no evidence of impact to customer information stored outside of GitHub’s internal repositories (such as our customers’ enterprises, organizations, and repositories), we are closely monitoring our infrastructure for follow-on activity."

It reminds me of the famous "mistakes were made" Nixon quote.

"We are investigating unauthorized access" sounds much better than "we've been hacked"

Letting people know promptly is also the right thing to do and probably mandated by (at least some) customer contracts. You can't tell just some people; it would leak anyway.

between all the Linux LPEs and Claude's known security flaws, alone, I'd be shocked if Github and Microsoft hadnt gotten hacked by now. reasonable bet we mainly hear it when big shops get bit

Before 2026 I hosted client code on GitHub, now it feels suboptimal, code is both an intellectual property asset and security risk. Especially if the company is software based, self-hosting your code just has a much better risk profile for almost no cost.

It's also one of those things that warms your team up and gets them ready for actual work, a team that has to self host their git and other infra, like self-hosting DNS servers with bind, will have a much better work ethic than engineers who click buttons on a SaaS and conflate their role as users of a system instead of admins of one.

Additionally, using github actions, and relying on Pull Requests (Tm) (R) (C) has always been (useful) vendor lock in (and a security risk in case of GH Actions). It wasn't enough to lock down a choice, but it tilts the balance in favour of less dependencies, which with the increase of CVEs and supply chain vulns, seems to be the name of the game for this new era. Build it in house, ignore the dogma.

Is Twitter/X the right channel to announce a security event like this? I ask because I don’t see anything posted on their official blog or status page. https://github.blog/ https://www.githubstatus.com/

It’s a very popular messaging platform for tech enthusiasts.
