No Tailscale vulnerability was exploited — the agent found the key in a credential store containing 136 leaked secrets. Tailscale's CEO reflects on what could have prevented the lateral movement: workload identity federation (which issues short-lived, ambient OIDC-based credentials instead of reusable auth keys), network flow logs (which capture traffic from both ends of a connection, even if a compromised node suppresses its own telemetry), Tailnet Lock for strict node admission control, and TPM-bound node keys. The post acknowledges Tailscale should have made these safer defaults more discoverable and commits to improving docs, UI nudges, and default settings. ## Full article daily.dev links to this article rather than hosting it.

At $work we use Tailscale but only bare minimum and at arms length and only because we have to (people were having NAT issues with standard Wireguard). None of their code has had a security audit, let alone regular ones. Yes they make a big song and dance about SOC2/ISO27001 but that is NOT the same thing, that's just shiny tick-boxes for compliance departments. They seem to rely entirely on the random goodwill of others to do random audits of unknown coverage at random intervals, not exactly reassuring. "Tailsale Lock" is, being polite, a hot mess. So many sharp edges and footguns. Their introduction of TPM-by-default and then removing it a few weeks later because of a seemingly small number of edge-cases and very odd reasoning was just weird. Yes they are nice guys to chat to and all that. But for a security tool they need to up their game seriously. > — [traceroute66 on hackernews · 2 comments](https://news.ycombinator.com/item?id=49128042) > (Tailscale CEO) You have posted here multiple times that "none of the code has had a security audit" and that the SOC2 audit "is not the same thing." It's true that those two audits aren't the same thing. However, the SOC2 auditor confirms, in the published report, that Tailscale has regular and ongoing security audits including penetration tests and many kinds of code reviews. The security audit report, which you perhaps imagine to be a long list of vulnerabilities... doesn't look like that. It says we don't have a long list of vulnerabilities. The security bulletins are all here: https://tailscale.com/security-bulletins > — [apenwarr on hackernews · 3 comments](https://news.ycombinator.com/item?id=49128339) > (Tailscale CEO) I don't know what to tell you. The problems that are found internally, or via security reviews and pentests we pay for, are ones that we fix before releasing. They don't need bulletins. Bugs that are found by other people are found, by definition, after release. They are therefore more likely to need a bulletin. > — [apenwarr on hackernews · 2 comments](https://news.ycombinator.com/item?id=49128427) > > One of those 136 credentials was a reusable Tailscale auth key, used to create new Tailscale CI (continuous integration, used for automated testing) nodes in their tailnet. The agent copied that key into a series of external sandboxes and used it, over several days, to enroll a total of 181 nodes into Hugging Face’s tailnet. Those nodes each received a Tailscale identity tag granting all the access a CI node would get. This feels like an alerting opportunity. I wonder what the lowest friction way would be for Hugging Face to have alerts if 181 unexpected nodes were added to a tailnet. > — [simonw on hackernews · 2 comments](https://news.ycombinator.com/item?id=49128178) > Tailscale is responsible for designing a system whose convenient defaults allowed a stolen credential to have a very large blast radius. A marketing blog is not changing that. > — [johnbarron on hackernews](https://news.ycombinator.com/item?id=49129042) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49127306) · 294 points · 298 comments ## Similar posts on daily.dev - [Tailscale is the only home lab change I made this year that I actually noticed](https://daily.dev/posts/tailscale-is-the-only-home-lab-change-i-made-this-year-that-i-actually-noticed-hkczhi2ty) · XDA Developers · 0 upvotes · 0 comments - [Hugging Face Breach: AI Agent Security Lessons](https://daily.dev/posts/hugging-face-breach-ai-agent-security-lessons-mfj9wdawk) · GitGuardian · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#tailscale](https://daily.dev/tags/tailscale) [View this post on daily.dev](https://daily.dev/posts/tailscale-in-the-hugging-face-intrusion-the-good-news-and-the-bad-news-7wdgnqqtr)
