Cisco Talos released CAIRN (Cognitive Artifact Intelligence Research Network), an open-source toolkit for identifying, classifying, and tracking malware that incorporates AI or large-language-model capabilities. Rather than requiring analysts to download or execute suspected malware, CAIRN hunts for metadata-based cognitive artifacts, including embedded prompts, LLM-provider endpoints, API-key prefixes, orchestration logic, local-LLM runtime references, and AI-focused evasion strings.
CAIRN combines acquisition filters, relationship graphs, a three-tier YARA classification model, and semantic clustering to link candidate samples with related infrastructure and campaigns. Talos reported that hunting of malware under active development since July 2025 showed a rapid shift from optional LLM features toward autonomous multi-model orchestration, alongside AI-specific evasion techniques appearing across independently developed malware. The company cautioned that AI-related artifacts can generate significant false positives and require reverse-engineering validation before attribution or definitive conclusions.

Cisco Talos reported that threat actors are increasingly using cloud AI tools such as Claude Code, CodeX, Cursor, and Gemini to support malicious operations, after analyzing prompt artifacts recovered from compromised endpoints. The research found three dominant use cases: AI as a malware and software engineering assistant, AI as a criminal force multiplier, and AI as an accelerator for vulnerability research and penetration-testing-style activity. Talos said existing model guardrails were often ineffective, with actors bypassing them through false ownership claims, bug-bounty or CTF pretexts, task decomposition across sessions, persistent persona conditioning, semantic evasion, or by moving to uncensored models. Case studies showed AI being used to help build DDoS tooling targeting Android TV devices, bulk email validation and phishing-adjacent infrastructure based on PowerMTA and Node.js, credential-harvesting workflows including abuse of exposed `.git/config` files and React2Shell techniques, and cryptojacking campaigns that used weak Deluge and qBittorrent credentials to deploy **XMRig**. Talos also documented AI-enabled scam and cryptocurrency theft activity, including a russophone scam chatbot, a hispanophone actor using an autonomous OpenClaw-based agent called **Alex** to target Telegram Mini Apps and **TON** wallets, and autonomous offensive frameworks such as **Hephaestus**; the firm warned that AI is lowering barriers for novice attackers while enabling more capable operators to scale intrusion, fraud, and exploitation pipelines faster.

Palo Alto Networks' Unit 42 reviewed 405 malware samples that incorporated AI and found that the vast majority were not active threats but proof-of-concept code, security testing artifacts, or malware merely branded around AI themes. Only 12 samples—about **3%** of the dataset—were observed on Cortex XDR-protected endpoints, and WildFire session data showed only roughly **15 to 20 unique hashes**, indicating that about **97%** of the samples remained confined to repositories, sandboxes, or validation environments rather than real-world operations. The operational activity that was observed mapped to five malware families: **FunkSec** ransomware, a trojanized AI-themed application, the **Oyster** backdoor, the **Rhadamanthys** stealer, and a **COM hijacking DLL**. Unit 42 said existing defenses, including behavioral analytics, sandboxing, code-signing anomaly detection, and entropy analysis, detected and blocked all observed samples, concluding that AI is currently being used more to speed malware development and strengthen social-engineering lures than to introduce fundamentally new runtime behavior or broadly successful evasion techniques.

Multiple reports describe threat actors abusing *AI-adjacent* and open-source distribution channels to deliver malware or manipulate automated agents. Straiker STAR Labs reported a **SmartLoader** campaign that trojanized a legitimate-looking **Model Context Protocol (MCP)** server tied to *Oura* by cloning the project, fabricating GitHub credibility (fake forks/contributors), and getting the poisoned server listed in MCP registries; the payload ultimately deployed **StealC** to steal credentials and crypto-wallet data. Separately, researchers observed attackers using trusted platforms and SaaS reputations for delivery and monetization: a fake Android “antivirus” (*TrustBastion*) was hosted via **Hugging Face** repositories to distribute banking/credential-stealing malware, and Trend Micro documented spam/phishing that abused **Atlassian Jira Cloud** email reputation and **Keitaro TDS** redirects to funnel targets (including government/corporate users across multiple language groups) into investment scams and online casinos. In parallel, research highlights emerging risks where **AI agents and AI-enabled workflows become the target or the transport layer**. Check Point demonstrated “**AI as a proxy**,” where web-enabled assistants (e.g., *Grok*, *Microsoft Copilot*) can be coerced into acting as covert **C2 relays**, blending attacker traffic into commonly allowed enterprise destinations, and outlined a trajectory toward prompt-driven, adaptive malware behavior. OpenClaw featured in two distinct security developments: an OpenClaw advisory described a **log-poisoning / indirect prompt-injection** weakness (unsanitized WebSocket headers written to logs that may later be ingested as trusted context), while Hudson Rock reported an infostealer incident that exfiltrated sensitive **OpenClaw configuration artifacts** (e.g., `openclaw.json` tokens, `device.json` keys, and “memory/soul” files), signaling that infostealer operators are beginning to harvest AI-agent identities and automation secrets in addition to browser credentials.
