AL-MUNAA: Collective Immune System for AI Agents
AL-MUNAA is an open-source local security layer for AI agents, created by Farhan Almutairi for OpenAI Build Week. It implements four protection gates—input/memory scanning, a tool/action gate, output verification, and a signed 'Threat Antibody Protocol'—so one agent can defend others against prompt-injection attacks without sharing raw secrets. The system uses HMAC-based fingerprints over normalized character shingles signed with Ed25519, includes padding-resistant containment matching and expanded HMAC sketches, and reports 74 passing tests. The project repository and demo are published publicly, and the author reports a controlled benchmark where the gate blocked a risky action before execution.
Open-source security tooling for AI agents is relevant to AI safety and agent deployments, but this is a single-project technical release with limited synthetic calibration and not a major platform policy or industry-wide change.

Defense Architecture for AI Agents Against Prompt Attacks
An open-source, four-layer defense-in-depth framework is presented to secure autonomous AI agents and LLM deployments against prompt injection, tool-poisoning, and escape/fugitivity. The design groups sensors and controls across: (1) input sanitization (text and visual), (2) gateway and sandboxing with policy enforcement, (3) runtime monitoring for each tool call, and (4) tool/data supply-chain protections for MCP servers. The framework lists named components (e.g., hermes-shield, vision-injection-guard, ai-guard-gateway, seblight, agent-shield-runtime, mcp-schema-sentinel) and includes post-hoc confidence validation using conformal prediction techniques. The codebase and architecture are available on GitHub and optimized for CPU-only local deployment under permissive/open licenses.
Import AI: fast16 malware, Muon flaws, positive alignment
Import AI (2026-05-18) summarizes recent AI research and related investigations: SentinelOne researchers examined a ~20-year-old virus called fast16.sys that stealthily patches floating-point code in memory to degrade high-precision scientific and engineering software (notably LS-DYNA 970, PKPM, MOHID). Tilde Research audited the Muon optimizer and reported a failure mode that causes persistent "neuron death" in MLP layers, and released Aurora, a leverage-aware optimizer, with code available on GitHub; small-scale tests show Aurora improving loss and benchmarks versus Muon and NorMuon. A multi-institution position paper proposes the concept of "positive alignment" — designing AI to actively support human and ecological flourishing beyond mere safety. Prime Intellect also reported agents (Codex / GPT-5.5 and Claude Code / Opus 4.7) autonomously optimizing nanoGPT training and outperforming human baselines in extensive runs.
Capability-Based Security Layer for AI Agents
An independent developer built 'Agent Firewall', an open-source capability-based authorization layer for AI agents that issues cryptographically signed, fine-grained permissions with full lifecycle tracking, attenuation, delegation, revocation, and replay protection. The project shipped v0.8 with SQLite-backed lifecycle persistence and includes 1,438 passing tests, architecture documentation, and a threat model. The author plans a v1.0 to freeze the API, ship full documentation, and make the library production-ready. The repo is available on GitHub and the library aims to replace binary API keys with time-bound, constrained capabilities for safer agent tool access (payments, APIs, databases, etc.).
