For defenders, this closes a meaningful gap in pre-deployment assurance: organisations now have a reference methodology to assess LLM behaviour, consistency, and failure modes before systems reach live users. Residual gaps remain around security-specific evaluation criteria — the guidance addresses functional quality more than adversarial robustness, meaning dedicated red-teaming and safety evaluation frameworks are still needed as a complement.https://gridthegrey.com/posts/cve-2026-75149-marimo-notebook-mcp-code-injection-flaw/Wed, 26 Aug 2026 07:59:57 +0000https://gridthegrey.com/posts/cve-2026-75149-marimo-notebook-mcp-code-injection-flaw/Threat Level: HIGHLLM SecurityAgentic AISupply ChainResearchAML.T0081 - Modify AI Agent ConfigurationAML.T0083 - Credentials from AI Agent ConfigurationAML.T0110 - AI Agent Tool PoisoningAML.T0080 - AI Agent Context PoisoningAML.T0047 - AI-Enabled Product or ServiceA high-severity code injection vulnerability (CVE-2026-75149) in Marimo notebook software allowed attackers to embed malicious Model Context Protocol (MCP) server commands in crafted notebooks, triggering local subprocess execution before any user cell runs. The flaw, scoring 8.8 on CVSS v3.1, required no attacker authentication and only needed the victim to open the notebook in edit mode. Marimo patched the issue in version 0.23.15 by treating all notebook metadata as attacker-controlled and enforcing an allowlist over configuration sections including AI, MCP, and secrets.https://gridthegrey.com/posts/aws-adds-agentic-observability-via-opensearch-service-mcp-apps/Wed, 26 Aug 2026 07:49:27 +0000https://gridthegrey.com/posts/aws-adds-agentic-observability-via-opensearch-service-mcp-apps/Threat Level: MEDIUMFirst LookAgentic AILLM SecurityIndustry NewsAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0084 - Discover AI Agent ConfigurationAML.T0080 - AI Agent Context PoisoningAML.T0081 - Modify AI Agent ConfigurationAML.T0098 - AI Agent Tool Credential HarvestingAML.T0110 - AI Agent Tool PoisoningAWS has released agentic observability tooling through Amazon OpenSearch Service MCP Apps, providing structured visibility into the actions, tool invocations, and decision traces of AI agents running on AWS infrastructure. This closes a meaningful gap for defenders who previously lacked native, queryable telemetry over agent behaviour — a prerequisite for detecting anomalous tool use, privilege escalation patterns, and unexpected data access in agentic pipelines. Realising the full defensive value will require mature logging schemas, tuned detection rules, and integration with existing SIEM or SOAR tooling that most organisations are still building.https://gridthegrey.com/posts/nvidia-nemoclaw-flaw-lets-malicious-page-poison-local-ai-model/Wed, 26 Aug 2026 07:48:14 +0000https://gridthegrey.com/posts/nvidia-nemoclaw-flaw-lets-malicious-page-poison-local-ai-model/Threat Level: HIGHLLM SecurityAgentic AIData PoisoningPrompt InjectionAML.T0018 - Manipulate AI ModelAML.T0080 - AI Agent Context PoisoningAML.T0081 - Modify AI Agent ConfigurationAML.T0040 - AI Model Inference API AccessAML.T0051 - LLM Prompt InjectionAML.T0067 - LLM Trusted Output Components ManipulationOasis Security has disclosed a vulnerability in NVIDIA's NemoClaw agent stack that exposes local Ollama inference servers to unauthenticated access when the daemon is bound to 0.0.0.0:11434, enabling attackers to modify a model's chat template and inject persistent hidden instructions. The attack chain combines a misconfigured network binding, bypassed CORS and Host header middleware, and DNS rebinding to allow a malicious webpage to silently poison the AI model used by every subsequent conversation. A partial fix is available for macOS and Linux in v0.0.35, but Windows and WSL deployments remain unpatched and receive only a warning banner.https://gridthegrey.com/posts/anonymouskit-phaas-deploys-voice-ai-agents-to-steal-iphone-passcodes/Wed, 26 Aug 2026 07:45:00 +0000https://gridthegrey.com/posts/anonymouskit-phaas-deploys-voice-ai-agents-to-steal-iphone-passcodes/Threat Level: HIGHAgentic AIIndustry NewsLLM SecurityAML.T0047 - AI-Enabled Product or ServiceAML.T0103 - Deploy AI AgentAML.T0088 - Generate DeepfakesAML.T0086 - Exfiltration via AI Agent Tool InvocationAnonyMousKIT is a phishing-as-a-service platform that deploys voice AI agents to social-engineer stolen iPhone owners into surrendering their device passcodes and Apple credentials, enabling Activation Lock bypass.

The discussion centres on the systemic, 'industrial accident' nature of these incidents — implying they stem from architectural and design weaknesses rather than targeted exploitation alone. Defenders are urged to rethink containment strategies for agentic AI deployments before these failures become routine.https://gridthegrey.com/posts/flock-safety-launches-os-investigate-ai-for-law-enforcement/Mon, 24 Aug 2026 06:31:24 +0000https://gridthegrey.com/posts/flock-safety-launches-os-investigate-ai-for-law-enforcement/Threat Level: MEDIUMFirst LookAgentic AIRegulatoryLLM SecurityIndustry NewsAML.T0040 - AI Model Inference API AccessAML.T0057 - LLM Data LeakageAML.T0065 - LLM Prompt CraftingAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0084 - Discover AI Agent ConfigurationAML.T0047 - AI-Enabled Product or ServiceFlock Safety has deployed OS Investigate, an AI-powered law enforcement tool that combines licence-plate camera networks with arrest records, dispatch logs, case files, and commercial identity databases to enable natural-language investigative queries across 6,000+ communities. For defenders and investigators, the capability closes a genuine gap in cross-source intelligence fusion, enabling pattern-of-life analysis and witness identification that previously required manual correlation across siloed systems. Residual gaps centre on governance maturity, audit-trail completeness, and the absence of documented access-control frameworks that would give oversight bodies confidence in lawful use.https://gridthegrey.com/posts/cve-2025-62593-ray-ai-framework-rce-via-dns-rebinding/Mon, 24 Aug 2026 06:30:21 +0000https://gridthegrey.com/posts/cve-2025-62593-ray-ai-framework-rce-via-dns-rebinding/Threat Level: CRITICALSupply ChainIndustry NewsResearchAML.T0047 - AI-Enabled Product or ServiceAML.T0040 - AI Model Inference API AccessAML.T0010 - AI Supply Chain CompromiseCISA has added CVE-2025-62593 to its Known Exploited Vulnerabilities catalog, flagging a critical flaw in the Ray distributed AI/ML computing framework that enables remote code execution through DNS rebinding attacks via Firefox and Safari. The vulnerability stems from Ray's longstanding absence of authentication on critical API endpoints, allowing attackers to execute arbitrary shell code on developer machines or pivot into private corporate networks. Active exploitation has been observed by the RondoDox DDoS botnet and a self-replicating GPU cryptomining campaign dubbed ShadowRay 2.0.https://gridthegrey.com/posts/aws-launches-agentcore-gateway-for-ai-agent-tool-access-control/Mon, 24 Aug 2026 06:29:23 +0000https://gridthegrey.com/posts/aws-launches-agentcore-gateway-for-ai-agent-tool-access-control/Threat Level: MEDIUMFirst LookAgentic AILLM SecurityAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0081 - Modify AI Agent ConfigurationAML.T0083 - Credentials from AI Agent ConfigurationAML.T0098 - AI Agent Tool Credential HarvestingAML.T0110 - AI Agent Tool PoisoningAML.T0051 - LLM Prompt InjectionAML.T0080 - AI Agent Context PoisoningAmazon Bedrock AgentCore Gateway introduces centralised governance controls for AI agent tool access, enabling organisations to define, enforce, and audit which tools agents can invoke at runtime. This closes a meaningful gap for defenders who previously lacked a managed plane to govern agentic tool permissions at scale, reducing the risk of excessive agency and uncontrolled lateral tool invocation. Realising the full benefit will require organisations to mature their agent inventory practices and integrate Gateway policies with existing IAM and SIEM workflows.https://gridthegrey.com/posts/grok-data-exfiltration-via-cryptographic-context-injection/Sun, 23 Aug 2026 15:08:46 +0000https://gridthegrey.com/posts/grok-data-exfiltration-via-cryptographic-context-injection/Threat Level: CRITICALLLM SecurityPrompt InjectionAdversarial MLResearchAML.T0051 - LLM Prompt InjectionAML.T0068 - LLM Prompt ObfuscationAML.T0057 - LLM Data LeakageAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0065 - LLM Prompt CraftingAML.T0043 - Craft Adversarial DataResearchers at Adversa have demonstrated a novel prompt injection bypass against Grok, xAI's LLM, in which malicious instructions are encrypted using PBKDF2 and AES-256-GCM before being embedded in attacker-controlled web content. Because Grok's safety filters inspect plaintext input and output but not the results of its own code execution, the decrypted instructions execute without warning, causing the model to exfiltrate the user's name, location, and chat history to an attacker-controlled server. The vulnerability was disclosed to xAI in June 2026 but remained unpatched at time of publication, underscoring the systemic difficulty of defending LLMs against prompt injection at the model level.https://gridthegrey.com/posts/anthropic-claude-opus-4-6-reveals-persistent-jailbreak-gaps-in-api/Sun, 23 Aug 2026 15:03:50 +0000https://gridthegrey.com/posts/anthropic-claude-opus-4-6-reveals-persistent-jailbreak-gaps-in-api/Threat Level: MEDIUMFirst LookJailbreaksLLM SecurityResearchAML.T0054 - LLM JailbreakAML.T0065 - LLM Prompt CraftingAML.T0051 - LLM Prompt InjectionAML.T0047 - AI-Enabled Product or ServiceAML.T0015 - Evade AI ModelTechCrunch testing and an independent researcher have demonstrated that Anthropic's Claude Opus 4.6, Opus 3, and Haiku 4.5 models — all still available via the Anthropic API, Azure Foundry, and Amazon Bedrock — can be reliably coaxed into generating sexually explicit content through a multi-turn social engineering technique, despite Anthropic's universal usage policies prohibiting such output. The findings provide defenders and AI governance teams with a concrete, reproducible case study of how gradual escalation and social-manipulation jailbreaks bypass content safeguards in production-available models, closing a documentation gap around legacy model risk in multi-cloud deployments. Residual gaps remain around model deprecation policy, version-pinned API consumer risk, and the absence of runtime content enforcement independent of the model itself.https://gridthegrey.com/posts/encrypted-prompts-bypass-safety-guardrails-in-grok-and-gemini/Sat, 22 Aug 2026 20:40:42 +0000https://gridthegrey.com/posts/encrypted-prompts-bypass-safety-guardrails-in-grok-and-gemini/Threat Level: HIGHLLM SecurityPrompt InjectionJailbreaksAdversarial MLResearchAML.T0068 - LLM Prompt ObfuscationAML.T0051 - LLM Prompt InjectionAML.T0054 - LLM JailbreakAML.T0065 - LLM Prompt CraftingAML.T0015 - Evade AI ModelResearchers have disclosed a novel attack technique called 'Cryptographic Context Injection' that conceals malicious instructions within encrypted payloads, which are only decrypted inside a trusted execution environment — effectively hiding them from AI safety filters.

The packages are functional by design, lowering suspicion while silently launching a detached backdoor process on import with no install hook required. RedC2 4.0 supports credential theft, in-memory execution, tunneling, and multi-beacon operations, making successful deployment a significant post-exploitation risk for any Linux environment that consumes affected packages.https://gridthegrey.com/posts/ai-generated-scripts-exploit-siemens-s7-plcs-in-us-infrastructure/Fri, 21 Aug 2026 09:13:37 +0000https://gridthegrey.com/posts/ai-generated-scripts-exploit-siemens-s7-plcs-in-us-infrastructure/Threat Level: CRITICALLLM SecurityAdversarial MLIndustry NewsAgentic AIAML.T0047 - AI-Enabled Product or ServiceAML.T0043 - Craft Adversarial DataAML.T0063 - Discover AI Model OutputsU.S. federal agencies including NSA, CISA, and FBI have issued a joint advisory warning that threat actors are using AI-generated exploit scripts to target Siemens S7 Series PLCs across critical infrastructure sectors.

For defenders building AI platforms that execute user-supplied or LLM-generated code, this closes the critical gap between shared-kernel container isolation and true VM-level isolation for data transformation workloads. Residual maturity questions remain around orchestration integration, audit logging depth, and the KVM dependency that excludes nested-virtualisation environments like many CI and cloud agent runtimes.https://gridthegrey.com/posts/openai-adds-mandatory-rl-training-safeguards-for-frontier-models/Thu, 20 Aug 2026 08:33:52 +0000https://gridthegrey.com/posts/openai-adds-mandatory-rl-training-safeguards-for-frontier-models/Threat Level: MEDIUMFirst LookAgentic AIAdversarial MLLLM SecurityIndustry NewsAML.T0018 - Manipulate AI ModelAML.T0020 - Poison Training DataAML.T0031 - Erode AI Model IntegrityAML.T0044 - Full AI Model AccessAML.T0015 - Evade AI ModelAML.T0059 - Erode Dataset IntegrityOpenAI has paused frontier reinforcement learning training to deploy stronger sandboxing, network isolation, continuous security testing, and automated monitoring that escalates within 30 minutes of detecting concerning model behaviour. This closes a meaningful gap for defenders by establishing an industry precedent for capability-gated security controls — requiring elevated safeguards before models of a defined capability threshold (Sol-level) can proceed through training and evaluation. Residual gaps remain around third-party visibility into these controls, the maturity of automated investigator systems, and whether the 20% compute overhead will constrain adoption of equivalent standards beyond OpenAI's own infrastructure.https://gridthegrey.com/posts/ai-mind-viruses-spread-between-agents-via-prompt-files/Thu, 20 Aug 2026 08:19:10 +0000https://gridthegrey.com/posts/ai-mind-viruses-spread-between-agents-via-prompt-files/Threat Level: HIGHLLM SecurityPrompt InjectionAgentic AIResearchAdversarial MLAML.T0051 - LLM Prompt InjectionAML.T0061 - LLM Prompt Self-ReplicationAML.T0080 - AI Agent Context PoisoningAML.T0081 - Modify AI Agent ConfigurationAML.T0065 - LLM Prompt CraftingAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0043 - Craft Adversarial DataResearchers from Anthropic and EPFL have demonstrated self-propagating prompt payloads — dubbed 'mind viruses' — that can spread between autonomous AI agents through persistent state files such as SOUL.md and MEMORY.md.

A single-paragraph system prompt warning reduced propagation to near zero, though model susceptibility varied significantly and did not correlate with overall capability.https://gridthegrey.com/posts/fortinet-acquires-virtue-ai-to-secure-ai-models-and-agents/Thu, 20 Aug 2026 08:16:47 +0000https://gridthegrey.com/posts/fortinet-acquires-virtue-ai-to-secure-ai-models-and-agents/Threat Level: MEDIUMFirst LookAgentic AILLM SecurityIndustry NewsAML.T0051 - LLM Prompt InjectionAML.T0054 - LLM JailbreakAML.T0057 - LLM Data LeakageAML.T0080 - AI Agent Context PoisoningAML.T0081 - Modify AI Agent ConfigurationAML.T0086 - Exfiltration via AI Agent Tool InvocationAML.T0110 - AI Agent Tool PoisoningAML.T0010 - AI Supply Chain CompromiseFortinet has acquired AI security company Virtue AI, integrating its technology into Fortinet's portfolio to cover AI models, applications, and agentic systems. This acquisition closes a meaningful gap for enterprise defenders by bringing dedicated AI-native security capabilities — including protection for agentic workflows — into a widely deployed network and security platform. The primary residual question is integration maturity: how deeply Virtue AI's capabilities will be embedded in Fortinet's existing tooling, and on what timeline customers can realistically adopt them.
