Is it just me or is this happening way more frequently in the last 4 or 5 months? Coincidently around the same time the models got a lot more capable?

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

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."

Are they required to announce that they're being hacked in real time?

The security issue aside, seeing more companies push announcements like these on X as the only official source is a trend I'm not sure I like. I can understand the rationale, this feels lighter and not something that belongs on status.github.com or the blog. Maybe what's actually missing is an official channel for ephemeral stuff on a domain they own, somewhere between a status page and a tweet? Just sharing an observation.

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.

Time to switch to Gitlab, Bitbucket or self-hosted

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/

Sympathy to engineers and everyone at github, it's good that they're being open even if findings are limited. I'm sure they will figure out the root cause and will publish results to be a learning experience for everyone else

bananamogul

I have a hard time believing this because there was never enough GitHub uptime to carry out the attack.

this is so amazing and brilliant display of the enshitification wow they won't fire the right people gauranteed maybe a slightly smaller ``bonus``

As some of us stated in the last weeks: Microsoft is working hard to get people to reconsider GitHub. All those small issues keep on adding up. Something is seriously flawed at Microsoft here - those problems did not exist in that way 2 or 3 years ago. It coincides with the rise of AI.

Is gitea any good?

GitHub: " Our current assessment is that the activity involved exfiltration of GitHub-internal repositories only. The attacker’s current claims of ~3,800 repositories are directionally consistent with our investigation so far." Oof https://xcancel.com/github/status/2056949169701720157

Grafana had a very similar incident: https://grafana.com/blog/grafana-labs-security-update-latest...
