GitHub describes replacing an LLM-based generic secret detection pipeline with a two-stage system. High-recall regex generates candidates, then a fine-tuned ModernBERT classifier scores each one using its file path, secret type, variable names and surrounding context. Training data mixes product feedback, weak-labelled regex candidates and synthetic hard negatives, with splits grouped by repository, value or example. The model is exported to ONNX with 8-bit quantization. Reported results against the LLM pipeline: 13% higher precision, 19% higher recall, 11.5% higher owner-weighted acceptance in an A/B test, 86% lower median post-push scan time and over 98% lower serving cost. It is a concrete case for using a small fine-tuned encoder instead of an LLM on a narrow, measurable classification task.

GitHub describes its secret scanning pipeline for generic secrets. Regex finds candidates with high recall, then a fine-tuned ModernBERT classifier reads the candidate with its file path, secret type and surrounding code to filter hard negatives such as placeholders, fixtures and checksums. The post covers the training data (product feedback, weak labels, synthetic hard negatives), grouped train/eval splits, and ONNX 8-bit quantization. Reported results against the earlier LLM pipeline: 13% higher precision, 19% higher recall, 11.5% higher owner-weighted acceptance, 86% lower median scan time and over 98% lower serving cost. The speed gain made generic secret detection feasible in push protection.

Galaxy Research analyzes the White House Accord on Super Intelligence, a voluntary pact signed by Google, Anthropic, Meta, OpenAI, Nvidia, and xAI committing to internal safety controls, auditing, and board oversight for cyber/bio/chem risks and unintended system access, alongside a Trump executive order renaming "artificial intelligence" to "super intelligence" in non-statutory government documents. The piece argues the accord carries no penalties, no disclosure requirements, and no government enforcement, framing it as an attempt to manage public anxiety (citing CNN/UMass polling showing majority fear of AI) rather than substantive regulation, and situates it against Leopold Aschenbrenner's Situational Awareness and the AI 2027 report's predicted regulatory trajectories.

StepSecurity recaps a 48-hour (May 18-19, 2026) software supply-chain attack wave that hit every pipeline layer at once: the Nx Console VS Code extension (2.2M installs) stealing tokens from GitHub/npm/AWS/1Password, the trusted GitHub Action actions-cool/issues-helper hijacked via tag replacement, a trojanized Microsoft durabletask PyPI package pulled within a 35-minute discovery window, a self-replicating Shai-Hulud npm worm, and GitHub's own disclosure that ~3,800 internal source repos were exfiltrated. The piece argues traditional SCA/SAST/EDR/CNAPP tooling missed all of it because none monitor CI/CD runner runtime behavior (e.g., attackers reading /proc/pid/mem to extract secrets) or developer-machine IDE extensions, and ties the incidents to StepSecurity's Harden Runner, Dev Machine Guard, Compromised Actions Policy and Secure Registry controls.

Socket.dev announced experimental scanning of VS Code Marketplace extensions (100,000+), extending its existing Open VSX coverage, to flag risky file/network/process access, obfuscated code, and hidden activation logic before teams install or auto-update developer tools. The post grounds the launch in two real incidents: the Nx Console supply-chain breach that let attackers exfiltrate ~3,800 GitHub repositories from a single poisoned extension update, and Socket's own GlassWorm investigation, which found four VS Code and six Open VSX theme extensions tied together by encrypted JavaScript payloads and a Solana-based dead-drop C2.

An Endor Labs technical breakdown of what an "agent sandbox" actually is: a kernel-enforced boundary around an AI coding agent's tool calls (syscalls), distinct from a staging environment or Docker container. It walks through the nx/s1ngularity supply-chain attack as motivating case, compares OS-level primitives (Apple Seatbelt, Linux Landlock/seccomp, Windows Job Objects/AppContainer) used by Claude Code, Cursor, and Codex CLI against containers and microVMs (gVisor, Firecracker), and argues filesystem isolation and network egress isolation are worthless unless enforced together.

Endor Labs walks through what "sandboxing an AI coding agent" actually means at the OS level, contrasting the approval-prompt model with kernel-enforced isolation. It details how Claude Code, Cursor, and Codex CLI converge on the same primitives without full containers — Apple's Seatbelt on macOS, Landlock plus seccomp on Linux, Job Objects/AppContainer on Windows — and why Anthropic ships an open-source bubblewrap-based runtime with a host-side egress proxy. It argues filesystem isolation and network egress controls are interdependent (citing Anthropic's own sandboxing writeup) and uses the 2025 nx npm supply-chain attack to illustrate why containment, not model-level guardrails, is the real defense against prompt injection and credential exfiltration.

A survey of how package managers confine install-time and build-time code. It covers Homebrew 7.0.0's fetch/install split, Landlock sandbox and signed declarative *_steps. It also covers opam, Nix, Bazel, pacman, Swift PM and Deno, and the open sandbox proposals at pnpm, RubyGems, Spack, Cargo, pip and Zig. It sorts the responses into gating (allowlists), confinement and replacement/removal of hooks. It links the topic to coding-agent sandboxes (Seatbelt, Landlock, bubblewrap) and to Shai-Hulud and nx. It argues the open problem is validating a sandboxed phase's output at the hand-off.

A deep-dive field guide to choosing between lattice-based (ML-DSA/FN-DSA) and hash-based (SLH-DSA) post-quantum signatures, built from interviews with the designers and implementers behind both NIST standards and their deployments. It walks through Mosca's-inequality-style migration timing, CNSA 2.0's split between lattice signatures and stateful hash-based LMS/XMSS for firmware, the stateful-signature "footgun," and why the broader internet (TLS/WebPKI, via Merkle Tree Certificates) is converging on lattices while Ethereum's post-quantum consensus roadmap (leanXMSS, EIP-8292, EIP-8288 aggregation) and Algorand's live Falcon-1024 state proofs lean hash-based or scheme-neutral because of aggregation and on-chain storage constraints. It closes with a decision framework and a rundown of NIST's round-3 "onramp" signature candidates (MAYO, SQIsign, HAWK, etc.).

Trail of Bits dissects 1Password's August 2026 report claiming AI agents (GPT-5.5, Opus 4.8) produce clean vulnerability fixes only 26% of the time, showing the figure is inflated by a hand-picked set of six hard bugs, deliberately-wrong-fix prompts (22% of trials), a no-testing mode (36% of trials), grading disagreements between automated graders and humans, and a buggy Linux upstream reference fix. Reanalyzing the same data under fair conditions (testable, non-adversarial trials) they find 86% of patches blocked the supplied exploit, and they contrast this with their own consulting data (12.5% of developer first-fixes fail) and Patch the Planet's 67.7% maintainer merge rate across 186 PRs, including a case where both a human maintainer and an agent independently introduced the same freenginx cleanup-crash regression.

Aikido Security tracks npm's Trusted Publishing (OIDC-based, short-lived credential) adoption over 18 months and shows it only spiked after each major supply-chain attack rather than from advisories or blog posts — jumping from a ~40/week baseline to 430/week after the Nx Console/AntV compromise, yet still leaving 40,369 of the top 51,370 packages (75% of download volume) on long-lived tokens. It chronicles the full attack progression from credential-phishing (Debug/Chalk, Axios) through Pwn Request-driven CI compromise (S1ngularity, Shai-Hulud 2.0) to the Mini Shai-Hulud II/TanStack attack, which poisoned the GitHub Actions cache to extract a live OIDC token from runner memory and publish packages with valid SLSA Build Level 3 provenance — proving Trusted Publishing itself can be turned into the attack vector rather than just bypassed. It closes by arguing the security community should proactively pressure high-download holdout maintainers rather than wait for the next worm.

Analysis of GitHub's July 28 change making npm scan every package for malware at publish time (roughly a 5-minute delay), instead of only reacting after reports. It covers the new dual-use governance model — contentPolicy metadata, DISCLOSURE files, and mandatory 2FA/OIDC publishing for tools like security scanners that resemble malware — and argues registry scanning can't enforce org-specific policy, can't cover other registries (PyPI, Maven, NuGet), and can't stop novel malware or compromised-account publishes, making install-time enforcement (e.g. Endor Labs' Package Firewall) still necessary.

GitHub released actions/checkout v7, which by default blocks checkouts of untrusted fork pull request code (via refs/pull/*/merge, fork head SHA, or fork repository) when running under pull_request_target or workflow_run-from-pull-request events, closing a long-known "pwn request" vector that grants attacker-controlled code access to base-repo secrets and GITHUB_TOKEN. The protection auto-applies to workflows pinned to floating major tags and backports to all supported versions on July 16, 2026; an allow-unsafe-pr-checkout opt-out flag is provided for workflows that intentionally need the old behavior. The article ties the change to real incidents (Nx supply chain attack, Shai-Hulud second wave via PostHog, and the TanStack compromise combining pwn request with cache poisoning and OIDC token extraction) and notes the fix only covers actions/checkout itself, not git/gh CLI or other checkout mechanisms.
