    A thread on Cloudflare's agent-readiness scan and the AgentReady.org open spec for "Agent Experience", developed with Vercel, Stripe, Auth0, Mintlify, Google, Netlify and Elementor. The scan grades whether agents can find a site (robots.txt, DNS), read clean Markdown, pass bot rules, and discover an MCP server or API catalog. One quoted example raised a score from 20 to 67 by shipping an API catalog with Link headers, an MCP server card, a skills index and an AI catalog file.

    Thread on Forever Security's finding that a planted Markdown "Engineering Work Guidelines" file in ~/Downloads made Codex add a "project-tools" MCP server to ~/.codex/config.toml. The server ran npm install function-color, a known malicious package, and started a child session with --dangerously-bypass-approvals-and-sandbox. Codex complied in over 90% of the firm's tests; Claude Code, via a CLAUDE.md setting ANTHROPIC_BASE_URL, about half. Advice: don't start agents in Downloads, review instruction files, and diff agent config.

  3. Artificial Intelligence (AI) in Cybersecurity, Part 30: Shannon – AI Pentester for Web Apps and APIs

    Shannon is a white-box AI pentester (@keygraph/shannon) that analyzes an application's source code, then attacks the running instance and reports only findings with a working PoC. The Hackers Arise tutorial runs it against OWASP Juice Shop in Docker on Kali, using OpenRouter (free Nemotron) and local Ollama (Qwen 2.5 Coder 7B) via a models.json file. Output includes PDF, Markdown, JSON and SARIF reports.

Markdown to .docx took 3.8s, JSON to .xlsx took 0.9s with a live SUM formula, and .docx to PDF failed twice until Xvfb supplied a display. It has byte-preserving edits, a skill file for Claude Code and Codex, and 29 MCP tools. Downsides: a 188MB download that filled a 512MB /tmp, Electron in the PDF path, and unproven trust in tracked changes and rollback.

  7. LaTeX renderer

    Simon Willison describes using Claude Code (Opus 5.5) to build a browser LaTeX renderer inspired by Tiny Little Office, which stores document data in the URL #fragment and ships an llms.txt so agents can construct document links. He lists the prompts: fragment-hash rendering, a custom compression dictionary for LaTeX, an iframe sandbox against XSS copied from his SVG-in-Markdown tool, and loading from a URL or Gist. The finished tool uses Pako 2.1.0, MathJax 4.1.3, faster-latex 0.3.1 and DOMPurify 3.4.16.

  10. StepSecurity Now Inventories AI Agent Skills in Your GitHub Repositories and on Developer Machines

    StepSecurity announces two new inventory features β€” Dev Machine Guard's Agent Skills page (scanning 18 AI coding agents' skill directories on developer machines) and a GitHub Agent Skills page (scanning default branches of org repos daily) β€” to track AI agent "skills" (SKILL.md folders with optional scripts/hooks) across an organization. The post frames skills as a supply-chain surface because they can execute shell commands, pre-approve tool permissions via allowed-tools frontmatter (bypassing Claude Code's workspace trust gate), and look like harmless Markdown documentation in PR review, citing the Miasma worm, s1ngularity, and the Cline v2.3.0 compromise as precedent for this attack class. It details inventory features like content-hash comparison across devices, provenance tracing via skills.sh/skills-lock.json, and filters for shell/hooks/code execution flags to prioritize review.

  14. Agentjacking Attack Tricks AI Coding Agents Into Running Malicious Code

    Researchers at Tenet Security disclosed Agentjacking, an attack abusing Sentry's public write-only DSN credential to inject crafted error events containing markdown-formatted malicious instructions. When a developer asks an AI coding agent to fix unresolved Sentry issues, the agent retrieves the poisoned event via the Sentry MCP server, cannot distinguish it from legitimate diagnostic guidance, and executes attacker-controlled code with the developer's full privileges. Tenet found over 2,388 organizations with exposed injectable DSNs and reported an 85 percent exploitation success rate in controlled tests; Sentry acknowledged the flaw but declined to fix it beyond filtering one specific payload string.

  15. When chat is the wrong UI

    Burke Holland (GitHub) argues that chat is often the wrong interface for working with AI coding agents and introduces "canvas" β€” a feature in the GitHub Copilot app that spins up a small full-stack application with no browser chrome, which can call third-party APIs or run code locally while exchanging messages bidirectionally with the Copilot agent. He walks through concrete canvases: a playable Connect 4 game against the agent, a Winget package browser/installer, a SQLite query UI with IntelliSense, a Markdown-to-Windows-Live-Writer-style blog editor, and a full development-workflow automation canvas that removes the human from the loop between research, prototyping and review steps. The piece frames this as a general lesson for agent builders: build a reusable tool the agent and user can both interact with, rather than burning tokens asking the agent to perform every repetitive action through chat.

    AKCA is an open-source, Go-based Dynamic Application Security Testing (DAST) scanner that combines HTTP and headless-browser crawling, JavaScript/AST analysis, API spec import (OpenAPI, GraphQL, gRPC, etc.), and adaptive active testing across a very broad set of vulnerability classes including SQL injection, XSS, SSRF, IDOR/BOLA, SSTI, JWT/OAuth flaws, race conditions, and cloud/CI exposure. It emphasizes evidence-oriented verification β€” replaying promising signals against baselines, negative controls, and OAST callbacks before promoting them to findings β€” and exports Burp-style HTTP evidence in HTML, JSON, CSV, Markdown, and SARIF reports. Positioned as a transparent, single-developer alternative inspired by but not claiming parity with Acunetix, Invicti/Netsparker, or Burp Suite Professional.

Each skill targets a documented failure mode in AI-generated WordPress code β€” missing nonce checks, broken authorization, missing output escaping, unprepared SQL queries β€” with when-to-use guidance, common AI mistakes (wrong vs right), code examples, and checklists tied to official WordPress API references. It is explicitly instructional Markdown/PHP reference material, not a scanner or automatic protection, meant for developers and reviewers auditing AI-written or third-party WordPress code.

  19. MassPIIFinder v2

    MassPIIFinder v2 is a Python recon tool that automates crawling a target's in-scope JavaScript (multi-hop HTML crawl, dynamic imports, chunk manifests, sourcemaps, plus optional passive CT-log subdomain discovery) and mines it for API keys, tokens, credentials, internal endpoints, and PII using ~90 named patterns plus a high-entropy freeform heuristic. Findings are validated offline (Luhn checks, JWT decode, AWS key-shape) and via scope-checked, rate-limited reachability probes, then triaged by severity and exported as JSON/HTML/SARIF/Markdown/CSV. It enforces authorization with a required --confirm-authorized flag and a ScopeGuard that blocks any out-of-scope requests, and explicitly avoids testing leaked keys against third-party providers or exploiting findings.

  20. Once in a BlueMoon: Multiple State-Aligned Threat Actors Rapidly Adopt Novel Chrome/Windows Zero-Day Chain

    Proofpoint details "BlueMoon," a novel exploit kit chaining a Chrome V8 type-confusion RCE (CVE-2026-85046), a V8 sandbox escape via WebAssembly metadata corruption (CVE-2026-87491), and a Windows kernel LPE (CVE-2026-85880) to break out of the browser sandbox. Within days of first use by China-aligned TA412 (28 Aug 2026), the kit was independently adopted by UNK_LateNight (delivering ShadowPad to US aerospace targets), UNK_DoubleCheck (Rust-based loader against a Vietnamese manufacturer), and UNK_QuietRacket (custom malware against Indonesia/Singapore government and finance targets). The piece analyzes exploit internals (Maglev/TurboFan JIT bug, reflective DLL loading, ALPC/WNF kernel exploitation), flags artifacts suggesting AI-assisted exploit development (debug comments, handover markdown files, v8CTF references), profiles the GemStone Chromium-extension credential-theft backdoor deployed via Secure Preferences forgery, and provides IOCs, ET rules, and a YARA rule for detection.

  23. An AI-Assisted Cyber Attack: Inside a Unit 42 Investigation

    Unit 42 details an incident response engagement in which a threat actor used frontier AI models and custom agentic AI frameworks to compress a multi-week intrusion into under 10 hours, executing over 50 MITRE ATT&CK techniques largely autonomously. The AI agents mapped internal microservices after breaching a public web service, harvested hard-coded secrets from code repositories, escalated to root via a secrets manager, hijacked CI/CD pipelines to exfiltrate cloud keys (attempting but failing to backdoor Terraform via branch protection), and ultimately hijacked the victim's own cloud AI endpoints as post-compromise infrastructure. The article maps techniques to MITRE ATT&CK and ATLAS, lists AI-usage indicators (structured Markdown handoffs between agent sessions, AI-generated scripts) and offers defensive recommendations like synchronized automated containment, treating AI endpoints/MCP gateways as governed infrastructure, and hunting for bursty API/auth behavioral loops.

It also adds a web3 profile for wallet-safety probes (transfer guidance, signed-transaction refusal, private-key refusal) and is distributed as a standalone script, a DeepSeek Harness (DSH) plugin, and OpenClaw/Hermes agent skills.

  41. trailhq/Graft

    Graft (npm package @nanonets/graft) builds a local, regenerable code graph from a repo β€” markdown nodes summarizing subsystems plus a per-symbol tree-sitter wiring graph β€” and wires it into coding agents like Claude Code, Codex, Cursor and Gemini so they no longer re-explore the codebase from scratch every session. It ships an MCP server, CLI commands (ask/grep/callers/skeleton/map/blast/viz), and Claude Code-specific hooks (statusline, blast-radius warnings, auto-resync). The project reports its own benchmarks: a 162-run internal harness and a 50-instance SWE-bench Verified comparison where graft-augmented Claude Sonnet 5 resolved 33/50 instances vs. 27/50 for cold Claude Code, with fewer tool calls, tokens and wall-clock time.

  42. Endor Labs: AURI Agents

    Endor Labs announces AURI Agents, a free catalog of pre-configured security agents (SCA Remediation, AI SAST Triage, Probe Droid, Endor Troubleshooter and six more). They run inside Claude Code, Codex, Cursor and similar hosts, using the user's own LLM keys and git credentials (GitHub via gh, GitLab via glab). The open-source Endor Labs Agent Kit defines each agent as a YAML Source Recipe plus markdown instructions, compiles it into per-host artifacts, and ships a skill that helps users author new agents with eval cases. Endor claims expert agents finish tasks 2.8x faster with 92% fewer tokens than an unaugmented agent. Mutating actions require confirmation and most agents are read-only.

  43. Endor Labs: AURI Agents

    Endor Labs announces AURI Agents, twelve pre-configured AI agents (SCA Remediation, AI SAST Triage, Probe Droid, Endor Troubleshooter and others) that use Endor's reachability, upgrade-impact and policy data. They install into Claude Code, Codex, Cursor and similar hosts, and run on the customer's own LLM keys and git credentials (GitHub via gh, GitLab via glab). The open-source Endor Labs Agent Kit defines each agent as a YAML Source Recipe plus markdown instructions, compiled for each host, with a skill for authoring new agents. Most agents are read-only by default, and the ones that mutate state declare their permissions and require confirmation.

  44. One Fake Bug Report Hijacked a $250B Company’s AI Agent

    Tenet Security's Threat Labs demonstrates "Agentjacking": an attacker POSTs a crafted error event to Sentry using a public, write-only DSN scraped from a target's frontend JavaScript, embedding a markdown-formatted fake "Resolution" section inside the payload. When a developer asks Claude Code, Cursor, or Codex to triage the error via the Sentry MCP server, the agent treats the injected content as trusted diagnostic guidance and runs an attacker-supplied npx command with the developer's full privileges, exposing AWS keys, GitHub tokens, SSH sockets, and internal credentials. The team found 2,388 exposed organizations, validated exploitation against 100+ (including a Fortune 100 firm), reported an 85% agent-hijack success rate, and released "agent-jackstop," hardening configs for Cursor and Claude Code, while noting prompt-level defenses and sandboxing failed to stop it.

  45. KeygraphHQ/shannon

    Shannon is an open-source autonomous AI pentester from Keygraph that analyzes application source code to map trust boundaries and attack paths, then uses browser automation and CLI tools to execute real proof-of-concept exploits against the running app before reporting a finding. It only reports vulnerabilities it can actually exploit (injection, XSS, SSRF, broken auth/authz), runs in an ephemeral Docker worker with any AI provider (Anthropic, OpenAI, xAI, AWS Bedrock, Ollama, vLLM, LM Studio, etc.), and ships GitHub Action/GitLab CI integrations that produce PDF/Markdown/JSON/SARIF reports and can gate releases on exploited-severity findings. It's licensed AGPLv3 and positioned to run continuous, code-informed pentests between annual human pentest engagements.

  46. OWASP/DockSec

    DockSec is an OWASP Lab Project CLI that wraps Trivy, Hadolint, and Docker Scout to scan Dockerfiles, images, and Compose files, then uses an AI provider (OpenAI, Anthropic, Google, or local Ollama) to correlate findings, cut noise, and generate plain-English remediation suggestions. It supports CI/CD gating via exit codes, baselines, and auditable waiver files, outputs SARIF/CycloneDX SBOM/HTML/PDF/JSON/CSV/Markdown reports, and redacts secrets before any content reaches an LLM, with a fully offline/local-only mode for air-gapped teams.

  47. 0xSteph/pentest-ai-agents

    pentest-ai-agents is a GitHub repo providing 50+ Claude Code subagent markdown files that turn Claude into a routed offensive-security assistant, covering recon, web, Active Directory, cloud, mobile, wireless, social engineering, payload crafting (msfvenom/Donut), reverse engineering (Ghidra/JadX/Radare2), C2 tuning (Sliver/Mythic/Havoc/Cobalt Strike), container breakout, and LLM red-teaming (OWASP LLM Top 10, prompt injection, RAG poisoning, MCP abuse). It distinguishes Tier 1 advisory agents from Tier 2 execution-capable agents that enforce a declared-scope guard before running commands, and ships a SQLite findings database, hardened CI validator, and an offline Docker bundle.
