Alpine Linux incident report on attempted exploitation of CVE-2026-97229 (CVSS 10.0), a regex-evaluation bug in Ruby's Onigmo engine reachable through GitLab CI configuration. An attacker crashed workers 8 times on 20 and 21 October 2026. Upgrading to GitLab 19.3.6 did not fix it because the patch sits in GitLab's bundled Ruby. Alpine rebuilt the instance and found no tampering with aports or releases.

Lean 4 proofs about the 504-byte EIP-7002 withdrawal-request contract on Ethereum, checked against the Jaune EVM semantics for Prague, Osaka, BPO1 and BPO2. The end-of-block system call always succeeds, using at most 210,000 gas. Requests leave in FIFO order. The post also gives counterexamples: code at the system address drains the queue, and the bytecode's 256-bit fee can undercut the EIP's fee.

Gheist is a campaign tracked by Wiz Research since 15 September 2026 that uses stolen GitHub tokens to push a sync-check workflow on ci-sync-* branches in every reachable repository. The workflow prints base32-encoded secrets into logs, which the tool downloads through the GitHub API and then deletes. Over 13,500 branches from 850+ accounts were recovered. The post covers the two tool variants, a buggy self-hosted runner payload, GitHub's approval hold (which does not cover private repositories), overlaps with other campaigns, hunting queries, IOCs and hardening steps.

CVE-2026-106173 is an unauthenticated arbitrary file write in the FortiSIEM phQueryMaster gRPC service on tcp/27918, advised by Fortinet on 13 October 2026. The SendQueryResult handler concatenates an attacker-controlled query-id into a path, and a null byte in the header removes the server-added filename suffix. Overwriting /opt/charting/redishb.sh, run every 60 seconds by cron, gives root-level code execution. IOCs are file timestamps.

Anthropic's Frontier Red Team reports that Claude recovered how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They are outputs of the C library's lrand48 LCG seeded with 1997–98 Unix timestamps, not hashes of a passphrase. The method scanned for weak-PRNG signatures, then used LLL lattice reduction to recover the truncated LCG state and stepped it back to srand48 initialization. Claude also traced some base points to the FreeLIP/NTL random generator. Reproducible Python is included. The authors say this is not an attack and makes deliberate backdoors less plausible. The B-163 seed and the base points of P-224/256/384/521 and the binary curves remain unexplained.

Anthropic's Frontier Red Team reports that Claude, given no hint, worked out how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They came from the C library's lrand48 LCG seeded with Unix timestamps from 1997–98, not from a hash of a phrase. Claude found this by scanning for weak-PRNG signatures and recovering the PRNG state with LLL lattice reduction. It also traced several prime-curve base points to the FreeLIP random generator. The post includes Python code that reproduces the seeds and base points. It says this is not an attack and makes backdoor claims less plausible. B-163 and the other base points remain unexplained.

Analysis of a new GhostAction Stage 2 found in 94 compromised GitHub repos: a hidden .vscode/tasks.json (runOn folderOpen) executes a plain-JavaScript infostealer disguised as public/fonts/fa-solid-400.woff2. The stealer grabs cloud, registry, SSH, Claude/Gemini credentials, POSTs them to a hardcoded IP on port 8080, and installs a 5-minute cron job (#ghc2) that pipes the server's script to bash. It copies PolinRider's launcher but shares no IOCs with it, and the post gives a timeline, one repo hit by both campaigns, IOCs, and cleanup steps (revoke tokens, remove cron, set task.allowAutomaticTasks off).

Blog adaptation of an Indie Rodeo talk arguing that LLMs struggle with games because much of a game is opaque non-code, and that this is a context problem. It prescribes concrete architecture so a game becomes its own agent harness: seeded randomness, a single "Thing" fat-struct object model, serializable commands, external data editable without recompiling, a standalone simulation core, odiff image diffing for screenshot evaluation, and samply text profiling. The aim is an agentic loop that runs in seconds per change.

VulnCheck reproduces and root-causes CVE-2026-76504, an exploited zero-day authentication bypass in Cisco SD-WAN vManage. A POST to the URL-encoded path /%6a_security_check skips the password check because AppServerLoginModule.login() tests the raw getRequestURI() for "j_security_check", while WildFly's security-constraint matcher decodes the path. Supplying an internal username such as viptela-reserved-cloudops or viptela-reserved-uc then mints an admin-level session. Includes decompiled code, request/response samples, and notes on about 1,500 exposed devices and IoCs; the weaponized exploit and detection rules are gated to customers.

Describes Resolve, a Kaggle benchmark of 16 single-function Python edits. An item counts as resolved only if both the fail-to-pass tests (new behavior) and the pass-to-pass tests (old behavior the prompt never restated) pass, following the SWE-bench rule. A second task, resolve-plus, adds a hidden edge suite. Results for 23 frontier and open models: GPT-6.1 Sol and GPT-5.6 Luna lead at 0.9375 on both tasks, while DeepSeek-R1, Sonnet 5.5 and Opus 5.5 drop from 0.9375 to 0.875. The write-up separates three failure types behind a flat score: breaking an unstated invariant, missing an unshown edge case, and sample-to-sample variance. It also compares score against output price per million tokens.

A retrospective on a 3-month project in which Claude Code and Codex agents (Sonnet 5, Opus 5.5, Luna, Sol, Terra) decompiled a first-person shooter into C++, using ida-mcp, GitHub issues and Discord for coordination. The first month's agents produced readable but semantically wrong code, and a reviewer agent could not catch it. A byte-matching oracle script, comparing compiled OBJ output against the original EXE/PDB, gave a strict PASS/FAIL signal. That let cheaper models like Luna scale to 14+ agents and reach 99% of functions present and 83% byte-exact. Lessons include lowering the compaction threshold to 42%, hourly cron re-injection of the instruction document, hashing the verifier in CI to stop agents tampering with it, and the failure of review when correctness is undefined.

Uber's engineering team describes how it extended its Zero Trust stack to give AI agents verifiable identities. Each agent workload gets a SPIRE SVID, and a Security Token Service checks an Agent Registry and mints single-hop, short-lived JWTs. Those tokens carry the full actor chain (for example user → Oncall Agent → Investigation Agent), loosely modelled on OAuth 2.0 Token Exchange (RFC 8693). The tokens are enforced at an MCP Gateway for tool calls, and an AI Gateway fronts model calls with guardrails. The post also covers an A2A client in the SDK that makes the secure path the default, observability of actor chains, and a 2026 roadmap toward dynamic access control and unified policy enforcement. It is a concrete production reference for agent attribution and delegated authorization.

It explains hook configuration in .claude/settings.json (matchers, JSON stdin payloads, exit code 2 to block) and the hook events: PreToolUse, PostToolUse, Notification, Stop, SubagentStop, SessionStart, UserPromptSubmit and PreCompact. Worked examples include sound and TTS alerts with pyttsx3, a regex guard against rm -rf and other dangerous Bash commands, TDD enforcement, auto-formatting with black, ruff and prettier, and session context loading. It adds troubleshooting and a cheat sheet, and its table of contents lists sections on multi-agent observability, slash commands, MCP tools, sub-agents and professional development patterns. The later sections are cut off in the fetched text. It is useful as deterministic guardrails and automation for a non-deterministic coding agent.

StepSecurity details a new wave of the GhostAction campaign in which attackers used compromised maintainer accounts of Takashi Kitao (pyxel) and Henry Wu (athenadriver, Uber) to push malicious "Security Audit" GitHub Actions workflows to 345 repositories in minutes. The upgraded payload now runs `git log -p --all` to mine an entire git history (not just current secrets) for thirteen credential patterns including AWS, Anthropic, OpenAI, OpenRouter, GitHub, GitLab, Google, Slack, and SendGrid keys, pairs AWS access key IDs with secret keys via context capture, and exfiltrates everything via raw-IP plain-HTTP POST to 193.32.204.199, bypassing DNS-based defenses. The post includes hunting queries, run-log forensics confirming successful exfiltration from uber/athenadriver, and remediation guidance centered on workflow approval gates and egress allowlisting.

Cisco Talos details UAT-11985, a spear-phishing campaign against Taiwan-based research organizations (impersonating institutions like the Taiwan European Union Centre and NCCU Institute of International Relations) that used AI-assisted, templated lure emails and poster-based QR code phishing (quishing) to drive victims to a real-time adversary-in-the-middle phishing kit. The kit impersonates Google sign-in across zh-CN/zh-TW/en locales, uses a split HTTP-POST/WebSocket architecture to mirror Google's live authentication flow and dynamically push MFA challenge screens, enabling full session-token theft and MFA bypass. Talos attributes the kit's localization architecture and lexical choices to a Simplified Chinese-speaking developer and publishes ClamAV/Snort coverage plus IOCs on GitHub.
