Tailscale replied on Reddit: Hi folks, Mike Shaver here, VP of Engineering at Tailscale. We've seen the concerns about Tailscale SSH and wanted to share what we know so far. If you want to jump to the most important part, based on our current assessment, we're not recommending that everyone disable Tailscale SSH. We've now received the researcher's report and are reviewing it. Our engineering and security teams had already been investigating independently, with help from external security specialists. That work has identified issues we're working to fix. We're still validating the full scope, including which configurations are affected. A bit of technical context: Tailscale SSH uses your tailnet's access policies to control who can connect to which machines. Most of the issues we've identified so far concern what happens after someone has been authorized to connect, particularly how Unix privileges and SSH forwarding are handled. In some cases, a session may be able to do more than the configured local user should be allowed to do. While it’s a serious concern, it isn't the same as an unauthenticated attacker being able to connect to arbitrary machines, but the potential impact depends on how SSH access is configured. We're still investigating, so we don't want to make blanket claims about what's affected or not. Again, based on our current assessment, we're not recommending that everyone disable Tailscale SSH. In the meantime, there are a few precautions you can take: •Review your SSH access policies. Make sure only the people and devices that need access have it. •Review SSH forwarding permissions and remove access you don't need. •Consider enabling SSH check mode for an additional authentication step. This won't fix privilege escalation issues, but it does add another barrier to gaining access. •Enable automatic updates where supported so you can pick up fixes when they're released. For particularly sensitive systems, consider temporarily tightening your Tailscale SSH access policies while we investigate, so that only the specific users and devices that need access can connect. We're working on fixes and testing them carefully. We'll publish a security advisory explaining the confirmed findings, affected configurations, recommended actions and available patches. We'll also follow up with a more detailed technical write-up. If we find anything that changes our assessment or requires immediate customer action, we'll communicate that. We know it's been a rough week for security teams, and we understand why people are concerned. We'd rather give you the technical context we have than speculate about things we haven't confirmed yet. We'll share more as we verify the details. If you have any questions about how this relates to your particular environment, please get in touch with our team tailscale.com/contact/suppor…

Gross incompetency from Indian certificate authority eMudhra. You had one job: generate a 384 bit private keys and instead you used: 4, 56, 66, 115, 155, 156, 230, and 237. This allows attackers to issue certificates for any websites. Embarrassing that it’s a family business run by largely computer illiterate people. Only 1 of the 3 have a remotely computer-related background and even they never actually worked a technical job in their life. If you look at the LinkedIn, their tech team is young, from tier 3 education and paid sort of bottom barrel. Imagine how many attacks you can design with AI given the existence of this genre of gross negligence.

Cyber is going to be one of the most profound aspects of AI. We now have a tireless workforce that can hunt down, discover, patch, or attack any system and software ever created. We will use agents to identify the long standing risks in existing systems and infrastructure. Attackers will use agents to accelerate the discovery of gaps in environments. We will equally use agents to defend attacks and discover anomalous patterns to better protect our data, and much more. We’re entering a new cyber regime, and we’ll probably use 100X more tokens on this loop than we’re imagining right now, because we can scan every log, look at every line of code, look through traffic, and process data at a scale that wasn’t comprehensible before. More than ever, enterprises are going to care deeply about how they manage their networks, systems, software, data, identity, devices, and more. Agents will largely become the solution to these challenges, but they will keep everyone up in the process.
