Last night an AI agent performed brain surgery on a mouse

A thread by Gabriel Ocana-Santero describing an AI agent that chose a gene therapy vector, brain region and stereotaxic coordinates, then injected 250 nL into a mouse epilepsy model through a custom Arduino surgery rig. A licensed vet gated irreversible steps with fixed validators, hash-bound approval and a physical kill switch. Opus 5.5 refused on detecting biology, while Opus 5 completed a dry run and stopped before live surgery. The technical report is still to come.

Smarthouse (@localyzapp) on X

A reply by Smarthouse (@localyzapp) on X to a question about the best harness for connecting local models to a Minecraft server. It suggests an MCP server that wraps RCON plus a small agent loop. The main pitfall is block coordinates: expose "/execute if block" as a read tool so the agent can check blocks before placing them, or it will hallucinate terrain.

ERC-8481: Agent Pre-Sign Risk Report

ERC-8481 is a draft Ethereum standard for the report a risk source returns about one unsigned transaction, EIP-712 request or x402 requirement. The report is bound to the request by a digest and EIP-712 signed by an ERC-8004 identity. It has five typed finding groups (tokens, approvals, addresses, payments, texts), each marked read or not read, and carries no score or verdict. The author's service toll is the only implementation; three design questions are open.

ERC draft: Independent Simulation Result for (STVA)

ERC draft "Independent Simulation Result" (STVA) defines a canonical, content-addressed SimulationResult (success, gasUsed, returnData, stateDiffHash, logsHash, snapshotId, resultHash) that any wallet, hardware device or verifier can recompute from the same VerificationPayload and state snapshot. It targets compromised-frontend and UI/calldata-mismatch attacks, and defines Basic, Standard and Strict compliance levels. Open questions are stateDiff encoding, prestate proofs and binding to capability tokens.

JFrog Security announces research on CVE-2026-102479 in Vert.x, which skips validating the letter 'L' in header names and so accepts `Content-Xength` as `Content-Length`. JFrog Research chained this with a dangling-byte primitive to bypass reverse proxy socket validation. They demonstrate end-to-end response poisoning and session fixation behind real reverse proxies. The post links to a full writeup; the tweet itself gives no exploit detail.

Proof of One: one-person-one-identity polling with encrypted ballots — design and reference code, requesting critical review

Proof of One is an open-source design for polls with one verified human per identity and unlinkable ballots. Enrolment proves in zero knowledge that an ICAO 9303 passport chip was signed by a trusted signer, plus an enclave face match. Voting uses threshold exponential ElGamal on Baby Jubjub with Groth16 proofs, and tally uses a GJKR DKG with a 7-day challenge window. The author, who is pseudonymous, discloses that AI agents drafted most of it and asks for critique of unlinkability, circuit completeness and certificate trust.

SemiAnalysis claims AMD chips running vLLM can earn up to $3 per chip-hour in profit serving the open-source Kimi K3 model, even after higher chip rental prices following Claude Code's rise. Kimi K3 has over 2.8 trillion parameters and fits AMD's 288GB per chip, while B200 cannot hold it in one server. B200 must then use tensor or pipeline parallelism over 400Gbit/s InfiniBand or Ethernet, which SemiAnalysis says is 18x slower than NVLink. The post gives no methodology.

It gives five setup steps (pip install with the mcp extra, npx skills add, locate mlx-lm-lora-mcp, codex mcp add). The prompt runs four pre-training trials on tiny-random/qwen3 with the mlx-community/recycling_the_web-1k dataset. Codex picks the optimizer and learning rate itself, and the result is a table with validation loss and the best adapter path.

MalwareTech thread arguing that many public "php2shell" exploits for CVE-2026-109618/CVE-2026-109619 are LLM hallucinations. The code shown is PHP session poisoning used to exploit local file inclusion in PHP apps, not a PHP vulnerability. It shares only the PHP_SESSION_UPLOAD_PROGRESS feature with the CVEs. Honeypot traffic shows non-working attempts, and AI-assisted triage wrongly confirmed mass exploitation. The real bug works only on a few PHP versions with specific configurations. Mitigation is setting session.upload_progress.enabled to Off.
