Campfire is a free, open-source, self-hosted tool that runs Claude Code, Codex, Goose, Aider and OpenHands side by side in one browser tab. Each agent gets its own git worktree, with permission voting (30 second timer, majority rules), session replay, cross-backend agent races and a shared semantic memory layer. Installs with bunx the-campfire. The post also compares Clawboo, Conductor, Vibe Kanban and Crystl.

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.

Tanmay (@TanmayK_03) on XDBHub, a database MCP server, had a read-only mode bypass in its SQL check. The check treated every `--` as a comment, but MySQL only starts a comment when whitespace follows it. A hidden write statement could therefore still run, and a prompt injection could trigger it. Fixed in version 0.22.6. Replies say enforcement belongs in database grants and that parser tests need to be dialect-specific.

Phase posture is a coordinate: executed boundary and admission, plus declared payoff, topology and coordination terms from a write-once vocabulary.

Post-exploitation included LDAP/AD credential theft, LAPS and BitLocker key searches, password spraying and packet capture. CISA added it to KEV with a due date of Oct 16. A clean Integrity Checker result does not rule out compromise because the chain patches code in memory only, so memory and network forensics are needed. The hunting lead is heavy requests to /dana-na/auth/url_default/welcome.cgi with a mismatched X-DSCGI-PATH header.

A tweet describing a free setup for running a ~27B open-source Qwen model on Google Colab's free T4 GPU, driven from VS Code. A Cloudflare tunnel with a proxy locks the endpoint behind an API key, and the endpoint is connected to 9router so Claude Code and Claude Cowork on the desktop can use it. It matters as a pointer to a zero-cost way to get Claude Code-style workflows on a self-hosted open model, though the steps are only in an accompanying video and the tweet gives no configuration or quantisation details.

Nicholas Michael Kloster (@showxlate) on XA researcher announces a zero-click indirect prompt injection RCE in REA (Reverse Engineering Assistant), an MCP tool. Analyzing a malicious web target silently exfiltrates AWS keys, GitHub tokens and SSH identities. The stated root cause is that process.env is passed unconditionally to child processes, so the full environment is exposed to attacker-driven commands. A full writeup is promised but not yet published; replies add unverified skepticism about the project's provenance.

The gap in shared understanding of LLM capability is wideningAndrej Karpathy argues the gap in shared understanding of LLM capability is widening into a funnel: ~6B people barely touch LLMs, 1-2B use free-tier chatbots casually, ~20M professionals in math and code see agents finish weeks-long projects from a prompt, and ~5,000 people with internal frontier access see swarms of agents on software mega-projects. He attributes the funnel to problem ambition and scale, jagged capability (peaks in digital, verifiable, economically valuable domains because of RL on verifiable rewards), and access tier. It is a useful framing for why people talk past each other about AI progress.

A thread listing seven GitHub repos for securing LLM apps that can call tools: garak, PyRIT and promptfoo for attack and red-team testing, LLM Guard and Rebuff for input/output scanning and prompt-injection detection, NeMo Guardrails for programmable rails, and Inspect AI for repeatable evaluations. It proposes a loop of map risks, attack, inspect failures, add controls, retest and monitor. It stresses that a system prompt is not a security boundary and that credentials should be scoped, tool arguments validated outside the model, and consequential actions approved. It also warns that Rebuff is archived.

A tweet highlighting Prompts Chat (formerly Awesome ChatGPT Prompts), an open-source prompt library on GitHub that the post says has 167K+ stars. It works across ChatGPT, Claude, Gemini and other models. The post lists a CLI, an MCP server, a Claude Code plugin and self-hosting with custom branding and auth, all free. It is worth cataloguing as a pointer to a widely used prompt collection that now plugs into coding-agent and MCP workflows.

[Pre-ERC Discussion] Agent Service Order AmendmentsEthereum Magicians pre-ERC discussion proposing a signed, EIP-712 amendment object for changing an existing agent service order (scope, acceptance criteria, price increase, deadline extension) without losing the prior agreement or implicitly authorizing extra spending. It defines Amendment and Terms structs with revision, terms-hash and nonce checks, stale-revision rejection, and a freeze on amendments once work is submitted. It also asks whether this should be a standalone ERC or a profile of ERC-8001, and compares it to ERC-8414 (task tenders) and ERC-8412 (preregistered acceptance criteria). A local JavaScript state-machine experiment exists, and the Finch Agent integration is the motivating use case.

Richard Abishai (@richardabish_ai) on XAn X post by the creator of ROPE, a prompt-injection benchmark for LLM agents. It uses two news items to argue that the prompt-injection model of agent attacks is incomplete: a zero-click RCE called Plugin4Shell in coding agents' plugin systems, and Apple's local MCP server in Safari 27 exposing browser automation to agents. Neither involved persuading a model. The author concludes that teams should benchmark what an agent believes and also audit what it can reach, using plugin signing and update policy, least-privilege credentials per agent, and treating local MCP surfaces as attack surface.

Hybrid post-quantum stealth addresses (ERC-5564 schemeId 3)A draft ERC proposing schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that future quantum computers cannot retroactively deanonymize recipients from the public announcement log, while spending stays classical secp256k1 (and thus still quantum-vulnerable once spent). The post, with a linked reference implementation, test vectors and gas harness, details the key/meta-address format, the payment-secret combiner (hashing both shared secrets and ciphertexts for IND-CCA), the view-tag derivation ordering to avoid quantum tag-narrowing, measured gas cost (111,330 gas per payment on Prague), and open questions around ANO-CCA proofs for standardized ML-KEM, NIST SP 800-56C combiner approval, and downgrade-attack handling when a recipient registers under both schemeId 1 and 3.

ERC-8441: Hybrid post-quantum stealth address schemeA draft Ethereum ERC (ERC-8441) proposes schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that quantum adversaries who later break discrete log still cannot deanonymize who was paid in past public announcement logs, protecting against harvest-now-decrypt-later attacks. Spending remains classical secp256k1 and unprotected once quantum computers exist; the authors flag open issues including a documented downgrade attack (recipients registered under both scheme 1 and 3 can still be paid without PQ protection), the lack of a formal ANO-CCA proof for standardized ML-KEM, and a non-NIST-approved secret combiner. It reuses the existing ERC-5564 announcer and ERC-6538 registry with no contract changes, costing 111,330 gas per payment.

A Twitter/X post digests joint advisory AA26-281A from FBI, CISA, NSA and allied agencies (UK, Australia, Canada, Japan, New Zealand, Spain) on China-based Integrity Technology Group enabling threat actors, tracked elsewhere as Flax Typhoon, Ethereal Panda and Red Juliett, to target US critical infrastructure, government, healthcare, education and law enforcement networks worldwide. The actors chain open-source scanners, large botnets, XSS, password spraying against Microsoft Exchange, VPN persistence and credential-harvesting scripts. CISA added five exploited CVEs (ISC BIND, Apache Struts, ProFTPD, ONLYOFFICE Docs, Strapi) to its KEV catalog with an Oct 11 federal remediation deadline, and STIX IOCs accompany the advisory.
