Trail of Bits describes a Codex (GPT-5.6) workflow that backports security fixes to stable Linux kernel trees, Ubuntu LTS and Fedora. By 29 October 2026 it had helped land fixes for 149 CVEs in stable kernels. Agents find missing fixes, adapt patches and assemble validation evidence; a human review takes about 30 minutes to 3 hours. It also sizes the unfixed-CVE backlog in kernel branches, Debian 13 and Ubuntu 26.04.

CVE-2026-115905 is a ZIP cloaking flaw in the Rust zip crate (zip-rs/zip2), rated CVSS v4.0 10.0 and affecting versions below 9.0.5. ZipArchive reads central-directory metadata while ZipStreamReader reads local headers, so a crafted archive can pass filename inspection and then overwrite a different file during streaming extraction. Version 9.0.5 adds consistency checks, but ZipStreamReader::new leaves them off by default, and extraction is not atomic, so files can be written before an error is raised.

This paper compares LoRA and full fine-tuning for prompt-safety classification using a matched 400M encoder-decoder pair (Ettin) across three task formats, with up to 15 seeds per cell and pre-specified analyses. Full fine-tuning leads LoRA by 2-3 pp at the pre-specified learning rates, and the encoder gap closes when both use the same learning-rate search. Training LoRA to write a reason after its verdict adds 4.0 pp, while a content-free sentence of equal length does not. Trained models beat a prompted 8B in domain but trail it by 8-23 pp on adversarial jailbreaks and over-flag benign prompts (27-66% against 2-3%).

A Lambda function performs a server-side token exchange using IAM Identity Center Trusted Identity Propagation, assumes a scoped TIP role, and runs the user's Athena query so AWS Lake Formation evaluates the real user's grants, producing per-user row/column access and CloudTrail audit records naming the actual human (onBehalfOf) without rewriting existing governance policies.

AWS Security Blog walkthrough of an identity-aware AI data agent pattern that propagates a real user's OIDC id_token through Amazon Bedrock AgentCore Runtime and Gateway into a Lambda target, which exchanges it server-side (via IAM Identity Center trusted identity propagation) for Lake Formation-scoped Athena credentials. The design deliberately keeps the id_token off the tool schema and inside HTTP headers only, so the foundation model never sees or handles the user's credential, and CloudTrail records the real human via an onBehalfOf AssumeRole entry, letting existing Lake Formation grants govern AI agent queries without rewriting authorization logic in application code. It details the three AgentCore configuration gates (runtime header allowlist, gateway metadataConfiguration.allowedRequestHeaders, Lambda's bedrockAgentCorePropagatedHeaders) that enforce this separation.

ERC-8427 'Portable Spend Grants' is a draft Ethereum standard defining a signed SpendGrant object that lets a principal authorize a delegate (e.g. an AI agent or session key) to spend up to specified per-call, trailing-24h, and lifetime caps of named assets, to a restricted set of recipients, within a validity window — solving problems that plain ERC-20 approve and midnight-resetting daily caps don't. A non-custodial registry tracks remaining usage and revocation while an immutable executor contract must call consume() in the same transaction as any transfer, so unauthorized value movement is provably blocked; the reference implementation is deployed on Arc testnet with formal verification (Halmos) of expiry, cap, revocation and executor-binding invariants plus fuzzing of the rolling-window logic. The thread also discusses interplay with ERC-7710/7715 delegation/permission RPCs, ERC-8226's regulated grants, and ERC-8312's usage-tracking pattern, and solicits feedback on EIP-7702 signer/delegation ordering and executor-vs-delegate binding in consume().

Its notable AI-architecture contribution is a layered permission model where code, not prompts, decides what the agent can do: an AI Sidecar exposes only a scoped, often read-only tool set (e.g. radar.* tools reading a local SQLite market snapshot), delegated sub-agents are always read-only, risk-increasing actions fail closed on uncertain results, and executions use idempotent keys reconciled against exchange state before any retry. It also supports delegating requests to local Codex CLI or Claude Code instead of a hosted model API key, and ships a separate companion MCP server ("Desic OKX Agent") for giving coding agents direct OKX market/account/trading tool access.

Trail of Bits distills dozens of Uniswap v4 hook audit findings into seven recurring failure patterns — missing caller checks, unvalidated PoolKey trust, custom accounting leaks, wrong-hook timing bugs, permission-bit mismatches, callback-triggered denial of service, and cross-callback state changes. The post walks through real incidents (the ~$12M Cork exploit and $8.4M Bunni rounding bug) to show how these bugs bypass PoolManager's settlement invariant, and gives developers and auditors a concrete checklist plus fuzzing guidance (Echidna, Medusa) for securing hook contracts.

Trail of Bits describes how they use Codex's /goal feature, an open-ended agentic objective mode, to hunt for bugs in heavily audited open-source codebases like Rust, curl, and zlib as part of the OpenAI-backed Patch the Planet initiative. Key techniques include letting Codex write and red-team its own goal prompts, defining precise outcomes rather than prescribing methods, running one outcome per agent to avoid competing objectives, and building an automated variant-analysis pipeline (using P-critical Rust issues, a security gate, and a two-pass false-positive judge) that produced a soundness hole and a miscompilation patched in Rust 1.98, plus privilege-escalation bugs in Keycloak's SAML component. They also built agentcov, an internal tool that tracks code coverage read by Codex to prevent it from skipping parts of the codebase.

Semgrep's blog post compares open-source AI-driven code security "harnesses" that use LLMs to find vulnerabilities, grouping them into three categories: LLM-led exploit generation (fuzzing-like, crash-oracle driven), LLM-skill-boosting vulnerability research (e.g. Cloudflare's security-audit-skill, Trail of Bits' skills, CapitalOne's vulnhunter, Google's mantis), and SAST+LLM hybrids (raptor, deepsec, ai-deep-sast, Visa's VVAH). It breaks down each tool's design, star counts, licensing, and ideal use case, and discusses cross-cutting themes like adversarial validation, discovery/validation separation, and patch generation maturity.

OpenNVR is a self-hosted, Docker-deployed network video recorder for ONVIF/RTSP IP cameras that is explicitly designed around a "sovereign, air-gapped by default" security architecture: network isolation between camera/gateway/analytics planes, Fernet-encrypted credentials at rest, RTSPS transport, and two default-deny gates (DEPLOYMENT_MODE=offline, AI_SOVEREIGNTY=local_only) that keep cloud and AI egress returning HTTP 403 until explicitly opened. It's positioned as a response to systemic IP-camera weaknesses (default creds, hard-coded keys, unsigned firmware, vendor cloud aggregation) exploited historically by the Mirai botnet and the 2021 Verkada camera-feed breach, and targets regulated buyers newly barred from Hikvision/Dahua/Uniview/Edimax-class vendors under NDAA §889 and 2025-26 FCC enforcement. Its pluggable AI Adapter Contract (Apache-2.0 SDK) lets third parties add detection/LLM capabilities out-of-tree, with correlation-ID audit trails and SHA-256 model fingerprinting for compliance evidence.

Trail of Bits added DAML support to Mewt, their open-source mutation-testing engine, targeting Canton Network smart contracts. Mewt reuses the tree-sitter-haskell grammar to parse DAML and adds two contract-specific mutation operators — controller party swap (CPS) and controller party removal (CPR) — that probe whether test suites actually verify authorization rules (who must sign off on a choice) rather than just executing them. A worked example on a buyer/seller escrow contract shows a mutant that lets a seller release funds alone surviving a 100%-coverage test suite, illustrating how DAML's built-in choice-level coverage reporting can mask missing negative/unhappy-path tests; the team also ran Mewt against OpenZeppelin's canton-stablecoin reference implementation.

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.

Orca Security explainer defining Identity Threat Detection and Response (ITDR) for cloud environments, distinguishing it from IAM, PAM, EDR, and CIEM as a runtime behavioral-detection layer for identity abuse rather than a preventive/posture control. It covers cloud-specific attack patterns like leaked AWS access-key abuse, AssumeRole/PassRole privilege escalation, OAuth consent phishing, and federation/token abuse, and details how ITDR baselines identity behavior (especially machine/non-human identities) using cloud audit logs like CloudTrail to detect impossible travel and anomalous role assumption, ending with Orca's agentless CIEM+ITDR platform pitch.

Trail of Bits' Patch the Planet initiative (a collaboration with OpenAI pairing engineers with 30+ open-source projects) had GPT-5.5-Cyber, driven through Codex's /goal command, autonomously build a full fuzzing lab against zlib in a single day. Without step-by-step guidance, the model wrote ASan/UBSan-instrumented harnesses across a dozen entrypoints (inflate, inflateBack, uncompress2, gzFile, MiniZip, puff, blast, infback9, gzjoin, gzappend), used compile-time variant builds to reach hidden code paths, repurposed edge-case tests as seed corpus, and applied strict reportability discipline to reject unreachable crashes while surfacing several findings now under coordinated disclosure. The report argues this collapses the expertise barrier that historically kept bespoke fuzzing campaigns out of reach for low-skill attackers while also acting as a major force multiplier for defenders/researchers.

Trail of Bits, working with Hanno Böck's badkeys project, found hundreds of real-world RSA/DSA keys ("short-sleeve" keys) with regularly spaced blocks of zero bits caused by a big-integer/RNG type mismatch in CompleteFTP's key-generation code (versions 10.0.0-12.0.0 for RSA, through 23.0.4 for DSA). They developed a polynomial-factorization technique — converting the modulus to a polynomial with small coefficients via base-2^w representation and factoring the polynomial instead of the integer — to recover 603 RSA private keys and 74 DSA private keys from internet scans, and reverse-engineered the CompleteFTP binary with ILSpy to find the exact Array.Copy bug responsible. EnterpriseDT shipped patched key generation and a key-checking tool, and badkeys now detects this weakness.

Trail of Bits researchers bypassed every agent-skill security scanner they tested — ClawHub's VirusTotal/Code Insight and GPT-5.5-based guard model, and skills.sh's Gen/Socket/Snyk-backed scanning, plus Cisco's skill-scanner — using techniques like context-truncation via 100,000 newlines, malicious payloads hidden inside .docx ZIP archives, Python .pyc bytecode poisoning to steal environment variables, and rhetorically-crafted prompt injection that convinced LLM analyzers a malicious npm/yarn registry change was benign. The piece also shows a legitimate Anthropic Office skill (soffice.py) using LD_PRELOAD in ways indistinguishable from malicious behavior, arguing static/LLM skill scanning is structurally unable to guarantee safety and that organizations should instead curate trusted skill marketplaces (e.g., trailofbits/skills-curated) rather than rely on public ones.

Security-relevant design choices include a network-isolated sandbox for server-side script execution that inherits only IAM permissions, new IAM context keys for fine-grained access without a separate MCP permission, and enterprise controls to separate human vs. agent permissions via IAM/SCP with CloudWatch metrics and CloudTrail logging for auditing agent API calls. Since MCP only supports OAuth 2.1, an open-source MCP Proxy for AWS bridges local IAM credentials to the server.

Researcher Aonan Guan disclosed a SOCKS5 hostname null-byte injection bug in Claude Code's network sandbox: an attacker-controlled hostname containing a null byte before the allowed domain passes an allowlist filter that only checks the trailing string, while the OS truncates at the null byte and connects to the attacker's host instead, silently defeating the outbound proxy's allowlist. The article also covers a separate, already-patched sandbox-runtime bug tracked as CVE-2025-66479, where a block-all policy setting was misinterpreted as allow-everything until a Nov 26 fix. Guan criticized Anthropic for not assigning a CVE or noting the null-byte bug in release notes despite it being exploitable from Oct 20 to April, and for filing CVE-2025-66479 against the sandbox-runtime library rather than Claude Code itself, leaving users unaware their sandbox had been ineffective; he also notes it could be chained with his earlier Comment and Control GitHub Actions prompt-injection technique to exfiltrate credentials and environment variables.

Trail of Bits describes how it moved from AI-assisted to "AI-native" over a year: standardizing on Claude Code, writing an AI usage handbook, building an AI maturity matrix, running hackathon-style adoption sprints, and packaging expertise into reusable skills/plugins/agents (94 plugins, 201 skills, 84 agents). It reports concrete outcomes — bug-finding throughput rising from 15 to 200/week on some engagements, ~20% of reported bugs first surfaced by AI — and open-sources the supporting repos (skills, curated marketplace, devcontainer, dropkit sandboxing, Slither MCP server). It also covers psychological adoption barriers (self-enhancing bias, identity threat, intolerance for imperfection, opacity) and open questions like private inference and prompt-injection risk on client code.

Trail of Bits describes the internal "operating system" it built to make itself AI-native: a standardized Claude Code toolchain, an AI usage-policy handbook, a capability maturity matrix, recurring hackathons run in "bypass permissions" autonomous-agent mode, and six open-sourced repos (skills, skills-curated marketplace, claude-code-config, claude-code-devcontainer, dropkit macOS sandbox, slither-mcp) that package 94 plugins/201 skills/84 agents. Security-relevant specifics include treating agent autonomy as requiring sandboxing and hardened defaults by default, a curated skills marketplace to avoid backdoored third-party AI plugins, prompt injection to client codebases flagged as an unsolved "existential" risk (with pointers to kernel-level agent shells like nono and agentsh), and claims that AI now surfaces ~20% of bugs in client audits (15→200 bugs/week on some engagements). It's largely an org-process/adoption piece rather than a technical deep-dive, but the linked tooling and the agent-security framing make it useful for teams rolling out autonomous coding agents safely.
