IA é só mais uma ferramenta, como qualquer outra que os devs já usam, e que a utilidade dela não é mais uma questão em aberto (mesmo reconhecendo que ela também gera dor de cabeça, tanto pela carga extra nos mantenedores quanto pelos bugs que aparece).
Quem critica a IA deveria olhar no espelho, porque “inteligência natural” também erra muito. E fechou dizendo que o kernel nunca foi um projeto “guerreiro social” as decisões são tomadas por mérito técnico, não por medo de ferramenta nova.

When Defenses Become Attack Surface: CVE-2026-20971, a Samsung Kernel UAF
LucidBit Labs research shows how Samsung's FIVE integrity subsystem exposed an app-reachable kernel use-after-free with multiple exploit-relevant primitives.

É isso. A mesma opinião que compartilho aqui sobre os modelos de IA: O quanto os modelos que precisam implementar guardrails por pressão governamental etc tendem a ficar pra trás do que os pesquisadores de segurança precisam
It’s becoming obvious that relying on frontier models is getting to be risky business. Either the model gets export controlled, or it gets nerfed with hidden guardrails. The second one is the more annoying problem for defensive cybersecurity work. When a model like Fable outright blocks anything security-related, that’s at least transparent, because we know upfront it doesn’t work for cybersecurity. The real problem is hidden guardrails, a frontier model quietly stops working for a use case and we can’t tell why, and sometimes an older version performs better than the new one (more on that later in the blog).

A IBM apresentou o primeiro transistor sub-1 nanômetro (7 ångstrons), baseado na arquitetura nanostack. Ela empilha transistores em três dimensões com canais condutores de apenas 15 camadas atômicas de espessura.
Com isso, espera-se estender a Lei de Moore por mais uma década. Em comparação com os chips de 2 nm de 2021, o chip experimental empacota quase 100 bilhões de transistores em uma área do tamanho de uma unha, quase o dobro da densidade do chip de 2 nm.
A nanostack promete trazer 50% mais de desempenho computacional e 70% mais de eficiência energética.

Writing a Debugger From Scratch - DbgRs Part 1 - Attaching to a Process
I’ve left the Microsoft Debugger Platform team twice, and each time I’ve started writing my own debugger. I must really like debuggers or something. This time, I have two reasons for writing a new debugger. The first is because I want to learn Rust better…

Chat, this is yet another Threat Actor using AI to slop up some malware. The only difference is this Threat Actor used professional level tools (although trial version) and put slightly more effort into the C2 and masquerading stuff.
If you'd like to see the source code I've reconstructed (and slightly more verbose writing), see post below this one.
