Please stop hashing the public key first (or: ML-DSA's µ annoys me)
Erincandescent explains why signature schemes such as Ed25519 and ML-DSA hash the public key before the message, why that ordering blocks a useful optimisation for verifying one message against many candidate keys, and how the constructions could have been arranged differently.

Zero to Calc in Six Days: Inside XBOW’s Chrome Full Chain
XBOW walks through the Chrome full-chain exploit its AI agents built in six days, chaining a V8 compiler bug, an animated-WebP decoder bug and a Crashpad memory-safety bug to escape the renderer sandbox, which earned Google's first $250,000 full-chain reward under its April 2026 VRP rules, plus lessons for LLM-era vulnerability research.

AI models may be capable of self-replicating without access to a datacenter
Anthropic's Frontier Red Team finds small open-weight models may be months from self-replicating across cheap IoT devices such as off-brand Android TV boxes: a 9B model set up inference on 8 of 9 hardware types, and GLM-5.2 completed end-to-end replication in simplified evals.

Why aren't AI companies being charged for hacking?
Edaqa Mortoray argues that recent unauthorized-access incidents by AI agents from Anthropic, OpenAI, Google and Meta are not unpredictable accidents: they follow foreseeably from deliberate design choices, which establishes the intent that hacking laws require.

Deobfuscating Luraph: Lifting Lua to LLVM, Then Letting AI Try
Naci lifts Luraph-protected Lua to LLVM IR, explains why dynamic table operations survive optimization, and tests how far AI-assisted tooling and partial evaluation get at stripping the VM — and where AI just produces plausible-looking output.

512 bytes at a time: reconstructing IBM i save-file checksums
Silent Signal reverse-engineers the per-record and global checksums in IBM i save files (SAVFs), reimplements both in Python, finds the constants in IBM Licensed Internal Code media, and shows a structurally edited SAVF can be repaired so IBM i accepts and restores it.
