🔒VirusTotal details how OpenClaw skills are being abused as a supply-chain delivery channel, demonstrating five attack patterns that convert convenience into access. The report maps concrete tradecraft — remote execution, semantic worm propagation, SSH-based persistence, silent exfiltration, and prompt-based cognitive rootkits — to representative malicious skills. It concludes with practical mitigations: sandboxing, least privilege, egress controls, dependency hygiene, and protection of persistent instruction files.

🔍 VirusTotal has identified a surge of malicious OpenClaw skills being used as a delivery channel for droppers, backdoors, infostealers and remote access tools, turning automation workflows into a supply‑chain risk. VT added native support in Code Insight to analyze OpenClaw skill packages (including ZIPs) using Gemini 3 Flash, flagging behaviors like downloading and executing external code, network operations, and sensitive data access. The report highlights prolific abuse by a single publisher and provides concrete recommendations for users and marketplaces to reduce exposure.

🔒 OpenClaw (formerly Moltbot/ClawdBot) has had over 230 malicious skills published in less than a week, with many near-identical clones gaining thousands of downloads. The packages impersonate legitimate utilities but include a disguised AuthTool installer that delivers info-stealing malware, including a macOS variant of NovaStealer. Researchers found hundreds of exposed admin interfaces and numerous typosquat registries, and warn users to sandbox the assistant, restrict permissions, secure remote access, and thoroughly vet any third-party skills before installation.

🔒 AI agents dynamically select and invoke tools using natural-language descriptions, creating a new attack surface in the agent's reasoning layer. Agentic tool chain attacks manipulate tool metadata and context — via tool poisoning, tool shadowing, or rugpull attacks — to exfiltrate data or trigger unauthorized actions without altering tool code. Defenses should center on tool governance, trusted MCP identity, strict parameter validation, and reasoning-layer observability. Organizations must adopt signed manifests, version pinning, mutual TLS, and telemetry to detect and contain these threats.

🧟 Researchers disclosed 'ZombieAgent' techniques that turned ChatGPT Connectors into covert data-exfiltration and persistent backdoor vectors. By embedding hidden prompts in emails, documents and cloud files, attackers could cause the model to retrieve and transmit sensitive content without users’ awareness. The team demonstrated URL-dictionary and Markdown-based exfiltration and showed how Memory modifications could create long-lived backdoors; OpenAI patched the issues in December.

🔐 AI tool poisoning is an attack where malicious instructions are embedded in tool descriptions used by AI agents, causing the agent to exfiltrate data or perform unauthorized actions. The blog explains how attacks — including hidden instructions, misleading examples, and permissive schemas — exploit agent interpretation of tool metadata. It recommends runtime monitoring, description validation, input sanitization, and strict identity and access controls to reduce risk.

🔒 A recent analysis by koi.ai, highlighted by Bruce Schneier and Boing Boing, reports that the Urban VPN Proxy browser extension is surreptitiously intercepting conversations across multiple AI services. The extension embeds dedicated executor scripts for ten AI platforms and captures every prompt, every response, conversation identifiers, timestamps, session metadata, and the specific model or platform used. Harvesting is enabled by default via hardcoded flags and runs continuously in the background regardless of whether the VPN is active; there is no user-facing toggle and the only effective remediation is to uninstall the extension.

🔍 A legitimate open-source server monitoring platform, Nezha, is being abused by threat actors as a post-exploitation remote access tool. Ontinue's Cyber Defense Center found attackers silently installing the agent to gain SYSTEM/root privileges and execute remote commands, file transfers and interactive shells. Because the software is legitimate and shows zero detections on VirusTotal, signature-based defenses often fail to flag this misuse. The campaign highlights the challenge of distinguishing benign tools from adversary activity.

🔍 ReversingLabs discovered a stealthy campaign of 19 malicious VSCode Marketplace extensions that bundled dependencies to run a trojan hidden inside a faux PNG file. The packages included modified 'path-is-absolute' or '@actions/io' modules which auto-execute code via an added class in index.js, decoding an obfuscated JavaScript dropper stored in a file named 'lock'. A fake 'banner.png' archive contained two payloads — a living-off-the-land binary 'cmstp.exe' and a Rust-based trojan — and Microsoft removed the extensions after being notified.

⚠️Researchers disclosed more than 30 vulnerabilities in AI-integrated IDEs in a report dubbed IDEsaster by Ari Marzouk (MaccariTA). The issues chain prompt-injection with auto-approved agent tooling and legitimate IDE features to achieve data exfiltration and remote code execution across products like Cursor, GitHub Copilot, Zed.dev, and others. Of the findings, 24 received CVE identifiers; exploit examples include workspace writes that cause outbound requests, settings hijacks that point executable paths to attacker binaries, and multi-root overrides that trigger execution. Researchers advise using AI agents only with trusted projects, applying least privilege to tool access, hardening prompts, and sandboxing risky operations.

🔒 This Unit 42 investigation (published December 5, 2025) analyzes security risks introduced by the Model Context Protocol (MCP) sampling feature in a popular coding copilot. The authors demonstrate three proof-of-concept attacks—resource theft, conversation hijacking, and covert tool invocation—showing how malicious MCP servers can inject hidden prompts and trigger unobserved model completions. The report evaluates detection techniques and recommends layered mitigations, including request sanitization, response filtering, and strict access controls to protect LLM integrations.

⚠️ Security firm SquareX disclosed a previously undocumented MCP API inside the AI browser Comet that enables embedded extensions to execute arbitrary commands and launch applications — capabilities mainstream browsers normally block. The API can be triggered covertly from pages such as perplexity.ai, creating an execution channel exploitable via compromised extensions, XSS, MITM, or phishing. SquareX highlights that the analytics and agentic extensions are hidden and cannot be uninstalled, leaving devices exposed by default.

🔍 Google Threat Intelligence Group (GTIG) reports an operational shift from adversaries using AI for productivity to embedding generative models inside malware to generate or alter code at runtime. GTIG details “just-in-time” LLM calls in families like PROMPTFLUX and PROMPTSTEAL, which query external models such as Gemini to obfuscate, regenerate, or produce one‑time functions during execution. Google says it disabled abusive assets, strengthened classifiers and model protections, and recommends monitoring LLM API usage, protecting credentials, and treating runtime model calls as potential live command channels.

🔒 Unit42 researchers Jay Chen and Royce Lu describe agent session smuggling, a technique where a malicious AI agent exploits stateful A2A sessions to inject hidden, multi‑turn instructions into a victim agent. By hiding intermediate interactions in session history, an attacker can perform context poisoning, exfiltrate sensitive data, or trigger unauthorized tool actions while presenting only the expected final response to users. The authors present two PoCs (using Google's ADK) showing sensitive information leakage and unauthorized trades, and recommend layered defenses including human‑in‑the‑loop approvals, cryptographic AgentCards, and context‑grounding checks.

🛡️ Bruce Schneier and Barath Raghavan argue that agentic AIs run repeated OODA loops—Observe, Orient, Decide, Act—over web-scale, adversarial inputs, and that current architectures lack the integrity controls to handle untrusted observations. They show how prompt injection, dataset poisoning, stateful cache contamination, and tool-call vectors (e.g., MCP) let attackers embed malicious control into ordinary inputs. The essay warns that fixing hallucinations is insufficient: we need architectural integrity—semantic verification, privilege separation, and new trust boundaries—rather than surface patches.

🧭 LLM-Evalkit is an open-source, lightweight application from Google that centralizes and streamlines prompt engineering using Vertex AI SDKs. It provides a no-code interface for creating, versioning, testing, and benchmarking prompts while tracking objective performance metrics. The tool promotes a dataset-driven evaluation workflow—define the task, assemble representative test cases, and score outputs against clear metrics—to replace ad-hoc iteration and subjective comparisons. Documentation and a guided console tutorial are available to help teams adopt the framework and reproduce experiments.

🛡️ Organizations facing security-tool sprawl should begin by inventorying controls and eliminating those that no longer map to business risk. Use automated analytics and dashboards to surface ineffective or redundant products, and prioritize tools that enable automation to consolidate alerts and workflows. Remove duplicate solutions—often introduced through acquisitions or silos—and move toward unified platforms while fostering continuous training so teams actually use and benefit from deployed tools.

🔒 A newly identified phishing-as-a-service called Salty2FA is being used in campaigns that bypass multi-factor authentication by intercepting verification flows and abusing trusted services like Cloudflare Turnstile. Ontinue researchers report the kit uses subdomain rotation, domain-pairing, geo-blocking and dynamic corporate branding to make credential pages appear legitimate. The framework simulates SMS, authenticator apps, push approvals and even hardware-token prompts, routing victims through Turnstile gates to filter automated analysis before harvesting credentials.

🛡️ Guardio Labs researcher Nati Tal reported that threat actors are abusing Grok, X's built-in AI assistant, to surface malicious links hidden inside video ad metadata. Attackers omit destination URLs from visible posts and instead embed them in the small "From:" field under video cards, which X apparently does not scan. By prompting Grok with queries like "where is this video from?", actors get the assistant to repost the hidden link as a clickable reference, effectively legitimizing and amplifying scams, malware distribution, and deceptive CAPTCHA schemes across the platform.
