In short: GitHub’s downtime is bad, but uptime numbers can be misleading. It’s not as bad as it looks; more like a D than an F.“Zero nines uptime”?99.99% uptime, or “four nines”, is a common industry standard. Four nines of uptime is equivalent to 1.008 minutes of downtime per week.GitHub is not meeting that, and it’s frustrating.

Learn how StepSecurity's platform directly mitigates every major risk identified in the report, from unpinned actions to day-of-release dependencies.

A week-long automated attack campaign targeted CI/CD pipelines across major open source repositories, achieving remote code execution in at least 4 out of 5 targets. The attacker, an autonomous bot called hackerbot-claw, used 5 different exploitation techniques and successfully exfiltrated a GitHub token with write permissions from one of the most popular repositories on GitHub. This post breaks down each attack, shows the evidence, and explains what you can do to protect your workflows.
