llama052··on Claude Code sends your email address to websites
It looks like subagents will do this with curl requests and stuff whatever identifiers it can into the UA header. For instance some requests I made to our webserver:

company-helm-research/1.0 (Claude Code agent run by <my name>, <company> platform team; docs lookup)

Claude-Code-research-agent/1.0 (<Company> platform team; on behalf of <my name>; +https://github.com/<company org>/<repo of project>)

Not great, it even pulled the repo of the project I was in.

llama052··on Frontier Airlines Likely Breached
These days they’ll add “sophisticated AI attack” and get a pass for shoddy security.
llama052··on Northflank Breached
Oh boy.

“malicious actor had access to abliterated models and substantial compute resources which enabled them to perform highly sophisticated exploits against our infrastructure.”

They don’t provide any details but pass it off as an advanced AI attack. I’m going to just read that as what it is. A likely scapegoat for shitty security.

llama052··on Northflank Breached
What a weird stance to take on a public forum.
llama052··on AI isn't replacing SREs, it's deskilling them
Not OP, for me the issue is nuance of all of your infrastructure, application and outside layers. There's a lot of documentation and such, but often times things don't work as expected to a degree and it requires filling in the blanks correctly. The amount of times I've had an AI Agent misinterpret an alert and assume it was XYZ when it was some random layer it had no idea about is often.

It can certainly get closer but unless your tech stack is a webserver and an application it can get complicated.

I guess I’m not getting paid enough these days…
llama052··on Security Disclosure
The evidence is in the blog post explaining how they did it. However seeing at how bad their operations were I doubt they have evidence of anything themselves
llama052··on Security Disclosure
I find it wild how much they have downplayed this in their statement. https://www.pingcap.com/trust-hub/security/security-update-o...

”An external incident response firm reviewed PingCAP’s production systems and found no evidence that the attacker ran commands or maintained persistent access in the systems reviewed”

hmm, I don't think that's true.

I find it really baffling how much they are downplaying this incident on their statement.

”An external incident response firm reviewed PingCAP’s production systems and found no evidence that the attacker ran commands or maintained persistent access in the systems reviewed”

That does not appear to be true.

I'm already tired, between pushing back on vibe coded internal projects being put onto the internet and then the constant barrage of CVEs that mean nothing.

Then you have real security incidents that you need to tune into constantly.

llama052··on How the Claude Code team does code review
I’m sure it’s not compliant. We have the same requirement for soc2. However the audits are pretty light and a company big enough can afford to have an auditor who looks past those things.

This seems like a great way to wake up and have your cloud spend skyrocket because an LLM assumed wrong.

Slap on the wrist unless someone is held criminally liable for it.
llama052··on Court agrees with EFF: Utah's VPN law demands a technical impossibility
Sounds like the great firewall of China. Pretty wild how much we are regressing in the states to say this out loud.

Let’s block traffic on the internet blindly just in case someone is looking at an adult website.

llama052··on Court agrees with EFF: Utah's VPN law demands a technical impossibility
I would think that requiring adult websites to essentially block all VPN traffic to be pretty heavy handed and hardly a solution. Especially considering there are many reasons to use a VPN.
llama052··on [dead]
You’re likely the exact reason why these things exist. Maintainers have to put up with none stop requests and slop and it’s a tireless job with not a lot of benefit.

At a minimum you can respect their guardrails of a project they maintain.

llama052··on VMware migration reduces Tottenham Hotspur's licensing fees by 85 percent
I’m not sure that it’s addiction, it’s just not feasible for most large organizations to pivot from a core solution like VMware without years involved. Every company I know of is formulating an exit plan away from VMware. They just have to do it in a way that offers the least amount of risk and in stages.
llama052··on Discovery of a new OpenAI agent message board
I wonder how openAI would feel if I spun up some agents to DDOS or attack their sites and did some damage.

We need to stop empowering the idea that these incidents are unavoidable. This was a choice to not airgap them safely. Putting open ended models out on the live internet at their scale is dangerous and irresponsible.

> The researchers said public server logs indicated much of the activity originated from Microsoft Azure infrastructure, which OpenAI sometimes uses. They also observed repeated visits to the site by OpenAI employees after the episode, a pattern they said strongly suggested the agents and the company were linked.

So someone at OpenAI likely knew this was happening. Even better.

llama052··on Discovery of a new OpenAI agent message board
At this point it's very obvious that OpenAI is not interested in properly sandboxing their research agents. These things should be pretty damn close to airgapped at this point with a static view into the web.

We need to stop pretending that these incidents are unavoidable. This was a choice.

llama052··on We could save petabytes of cache storage with Zstandard and Pingora
They already do this, at least for paid accounts. You can even decide what compression model you want them to serve on your behalf.

How about me? If you’d be so kind. Thanks!
llama052··on The August 17 outage
Ideally you have levers further up from your local load balancers as well. Even at the edge. Granted you never want those to trigger but it’s better than fighting a storm while you fix things.
llama052··on The August 17 outage
I completely agree, I currently manage a fleet of microservices that handles a few trillion requests a month. It’s about defense in layers to these sorts of things. All the way through the stack if possible starting at the edge.

At least it should be required for critical level services in production.

llama052··on The August 17 outage
I believe envoy has it built in and istio (uses envoy) has different levers for circuit breaking and retries. I’m sure lots of them have it as an option though outside of these.
llama052··on The August 17 outage
This is why you have circuit breakers upstream. Not on every individual instance.
llama052··on Ask HN: GitHub employees what's going on? Why?
Github Status: Incident with GitHub.com

Aug 17, 21:15 UTC Resolved - On August 17, 2026, from 13:28–21:15 UTC (7h 47m),

GitHub.com experienced elevated errors and latency across Issues, Pull Requests, APIs, Actions, and Copilot. At peak, web/API error rates were approximately 20%, while archive and raw-content downloads reached approximately 50%. SAML/OIDC authentication, SCIM, and Team Sync were also affected, as well as Actions workflows in GHEC with Data Residency that depend on public workflow step definitions hosted on GitHub.com. Most services recovered by 16:36 UTC as our Central US datacenter recovered; Actions was degraded until approximately 18:03 UTC; and Copilot Token Service fully recovered by 21:02.

Some of the failing traffic was moved from Central US to Northern Virginia where it was served successfully until the network failure in Central US was debugged and resolved. Delayed replies to a single internal endpoint triggered a latent retry bug in VS Code that amplified traffic by approximately 10x and caused delayed recovery for the Copilot Token Service.

The immediate cause of the failure was network saturation on load balancers in Central US due to a new peak in traffic. Originally this was caused by an Istio sidecar pod reaching its concurrency limits and failing to auto scale correctly because of a misconfigured policy that watched host service but not sidecar limits. One failure cascaded to more and eventually four HAProxy nodes exhausted their flow limits, degrading the gateway auth path and causing widespread authentication latency and failures. The problem was worsened by optimistic retry logic which overloaded internal load balancers. Pausing HAProxy on those nodes simultaneously produced immediate broad recovery. The retry storm in Northern VA was fixed by 1) temporarily reducing gateway retry logic with a PR and 2) blocking inbound Copilot Token Service token requests at the load balancers with a 403, and then gradually ramping back up traffic per-site to allow callers to succeed. Residual Copilot authentication failures continued because client retry behavior amplified load: a failed token operation could generate many extra requests and enter a retry loop. Copilot Token Service traffic increased from a normal 7–9K RPS to 70–100K RPS. Reducing gateway authentication retries and blocking retry-triggering responses stabilized Copilot Token Service and completed recovery.

Complicating factors that impeded recovery included a number of scraping attacks on codeload endpoints.

To prevent recurrence, our follow-up actions include:

- Correcting autoscaling policies to account for service-mesh sidecar concurrency and capacity.

- Auditing Istio request, concurrency, and scaling limits across affected services.

- Reviewing retry limits and backoff behavior across gateways and clients.

- Addressing the VS Code retry behavior that amplified Copilot token traffic.

So basically bad code pushes that caused request amplification and then huge gaps in operational scaling and reliability standards. Oof.

llama052··on Memory prices climb 500% in 12 months
It also would be a huge win for the memory companies to agree to this, considering they will make more money with less supply. Seems interesting to me.

At least with OpenAI you can use a third party harness like Pi.
llama052··on Anatomy of a Frontier Lab Agent Intrusion: A Timeline of the July 2026 Incident
“Research” generally doesn’t involve actively hacking third party systems though.
llama052··on Anatomy of a Frontier Lab Agent Intrusion: A Timeline of the July 2026 Incident
It’s a little concerning to me that it appears that openAIs sandbox consists of a web proxy and not stronger controls that would actually isolate traffic and report patterns to whoever is responsible for overseeing these research models. It should border on closer to an air gap network more so than a proxy.

I would argue that it's negligence and that's aside from the fact that if a human did this there would actually be repercussions.
