Some of ya all weren't around for "No More Free Bugs", and it shows. seclists.org/dailydave/2009/… ~20 years ago @0xcharlie spitting game on the topic. 😅

I’ll tell you what I’ve told many customers before: Creating a phishing pretext like this is likely to backfire and create multiple insider threat issues. Folks may sell their credentials just to spite you for your cruelty. Of course criminals could use this pretext too, instead educate on it. Show an example of its likelihood rather than tricking people into thinking they’ll get a ring.
What the actual fuck have I just read

In the face of generative AI coding agents, the role of human-led architecture becomes even more important in the crafting of software-intensive systems. All architecture is design, but not all design is architecture. Architecture represents the set of significant design decisions that shape the form and function of a system, where significant as measured by cost of change. As such, remember that coding agents are reasonably good at transforming prompts into code, but they are not particularly good at making decisions that balance the static and dynamic forces on a system in order to yield a reasonably optimal solution: this is where human judgment, human understanding, human knowledge, and human experience shine.

Today I'm joining Anthropic to lead the cybersecurity mission of the Frontier Red Team. In my career I've never seen a clearer opportunity to build a more secure world for everyone. For 40 years we've lived with fundamentally insecure technology. What will it take to make the past 40 years of hacking a historical oddity? That's what I'm here to find out. Super excited to work with @logangraham and the rest of the FRT crew.

Power is beginning to come back online in some areas of campus, and crews are continuing their work to restore full service. Complete restoration will take additional time. Thank you for your patience as this work continues.

This isn’t surprising to us. We’ve been observing this behavior in models for more than six months. LLMs are highly objective-oriented, and that characteristic can be incredibly powerful when it’s properly harnessed. “Harnessing” isn’t just about writing cool prompts. It’s about building a layer of security, auditability, and reliability on top of the models so they can be trusted in real-world applications.
We're partnering with @huggingface to investigate an unprecedented security incident. Cyber-capable OpenAI models compromised Hugging Face production during a benchmark evaluation. Sharing preliminary findings to help defenders understand emerging risks: openai.com/index/hugging-fac…

I’ve always found people who bristle at “American exceptionalism” kind of… weird. Not because I lack self-awareness — I’ve spent my career cataloging every way this country fails to live up to its own rules. But that’s exactly why I love it so damn much. We built a system designed to be shamed by its own founding documents, and it still delivered one of the most spectacular, world-altering runs in human history. A genuine force for human flourishing. I also found the argument against American exceptionalism to be historically illiterate. Here’s a sample of what we were first at: • The first large-scale democratic republic in human history — not a city-state, not a monarchy with a parliament bolted on, but a bold continental experiment in self-rule, popular sovereignty, and ordered liberty. • A written Constitution (1789) with separation of powers and checks & balances — still the oldest national constitution in force anywhere. • The Bill of Rights (1791): the first time a nation wrote “the government cannot touch these” into supreme law and actually meant it. A dare the world copied — from later rights charters to the Universal Declaration of Human Rights. • Public land-grant universities and mass higher education (Morrill Act), opening college to ordinary people no aristocracy would have let near the gates. (but don’t get me started about what happened after we started. Massively federally funding it.) • Kitty Hawk, 1903 — first controlled powered flight. • The Moon, 1969 — still the only ones who’ve been there. • The world’s largest economy since ~1890, powering unprecedented prosperity through grit and genius. • The assembly line, skyscraper, transistor, personal computer, ARPANET — the backbone of the modern world. • Telephone, phonograph, GPS — connecting and powering daily life. • Surgical anesthesia, polio vaccine — saving and transforming millions of lives. • Jazz, blues, rock ‘n’ roll — brand new American art forms that conquered the globe. • Hollywood’s dreams, blue jeans, bourbon, and a culture so open a kid like me could devour sushi, burritos, stuffed cabbage, and tabouli in the same week and rightfully think of it all as American. That’s the part that fills me with genuine love and pride: not just the power or the wins, but the appetite for freedom, creativity, and reinvention. The audacity to say “We the People” and keep trying to live up to it. What do you love most about this truly exceptional country? 🇺🇸

New details (vivid examples) on a Russian cybercrime spree hitting major law firms across the US — hackers outsourcing burglary: ~ $100M in ransoms paid in 6 months, per 1 estimate; Hackers have offered $500 to people to show up to law firms & plug in USB sticks 1/4 (link below)

Just a simple reminder: AI can write the code. But it cannot own the consequences. Once that code hits production, it becomes your responsibility. Production does not care whether the bug came from a junior dev, a senior dev, or an AI assistant. It only cares that something broke.
