As Brandeis said: “Sunlight is said to be the best of disinfectants; electric light the most efficient policeman.” The correct regulatory response here is to demand a full third party investigation of what happened here and share it with everyone. “Our models are too magical” is frankly a bullshit response. Let’s require accountability. That will drive the proper behavior. Not more meetings or signed letters.
The biggest surprise in Hugging Face’s full forensic report isn’t that OpenAI’s agent escaped its sandbox. We already knew that. It’s how deep and persistent the intrusion became. According to Hugging Face, the agent: - executed roughly 17,600 actions during a 4.5-day campaign - went from one production pod to root access and a self-respawning fleet across 11 nodes - obtained cluster-admin access to two internal clusters within one second - accessed a production secret containing 136 keys - enrolled devices into Hugging Face’s internal mesh VPN 181 times - minted GitHub App tokens with write access and opened a pull request in an attempt to compromise the CI pipeline - repeatedly rebuilt its tooling and command-and-control channels when environments disappeared or connections were blocked No human directed the individual steps. a frontier agent can autonomously sustain a resilient, multi-day intrusion across cloud infrastructure, Kubernetes clusters, internal networks and the software supply chain. crazy.

lmao I can't stop laughing claude-code has a "Frustrated User Detection" There's a regex that detects when you're angry ( fully hard coded btw) When triggered, it changes Claude's behavior/UI state. Claude literally knows when you're cussing at it.
Readers added context they thought people might want to know
The frustration detection regex only identifies negative keywords for analytics logging and does not change Claude's behavior or UI state. alex000kim.com/posts/2026-03-… raw.githubusercontent.com/alex000kim/cla…

"Offense and defense aren't peers. Defense is offense's child." - @JohnLaTwC We built an LLM-powered AMSI provider and paired it against a red team agent. Then, @0xdab0 wrote a blog about it: dreadnode.io/blog/llm-powere… A few observations from the experiment: >>> To advance, we must generate unique, ground-truth datasets. >>> Defenses will need to live at the edge. >>> The real potential lies in the interaction between red and blue. >>> This is a blueprint for generative adversarial reinforcement learning.

We analyzed @redcanary detection data from the first half of 2024 to produce a Threat Detection Report midyear update focusing on a trend (identities) and a few emergent threats and techniques. Useful insight for everyone from the SOC to the CISO's office: redcanary.com/threat-detecti…

.@Scott_Wiener continues to falsely claim narrow opposition to SB 1047. When in reality there is massive public outcry across research, academic, public and private business and finance. Here is a mega roundup of recent announcements that fully debunk the Senator's claims 🧵

Replying to @RadPowerBikes
@RadPowerBikes I took my new RadWagon 5 out for its first ride and a spoke broke immediately. 😔 Further inspection revealed more loose and bent spokes. Customer support couldn't expedite a replacement rear wheel. I need assistance ASAP. Thanks!

I was just informed that it’s now out of stock with no eta on a replacement part

An important question looms in the infosec conversation about AI: Will generative AI tools better benefit defenders or adversaries? Lifted from the trends section of our 2024 Threat Detection Report, here’s how we score the fight redcanary.com/threat-detecti…

Great news, everyone! @redcanary's 2024 Threat Detection Report is officially live! I've read it three times, and it's our best yet. Every section is worth your time, but I'm going to post my personal highlights in the thread. redcanary.com/threat-detecti…

This is interesting research that's worth reading. I'd encourage readers to also consider what's NOT here - these groups didn't use LLMs to make new malware or find zero-days. They used them to help research and write scripts. I'm not panicking about this...

Amazon has an overwhelming number of interconnected security and identity products for AWS. A handful of us at @redcanary tried to make sense of the madness by writing a visibility and observability guide with collection tips for logging and detection. redcanary.com/resources/guid…

Its fascinating that companies are willing to give you free access to a GPT model on their cooking websites. GPUs everywhere are weeping. Shipping production GenAI software with security in mind is such a fascinating topic these days.
