AI Security Daily Briefing — February 18, 2026

A fact-based update for security and risk professionals, focused on how AI is reshaping the threat landscape and the defensive stack.


🔐 Core Security Intelligence

“AI as a C2 Proxy”: Assistants Abused as Stealthy Command Relays

Check Point researchers have disclosed a novel technique where AI assistants with web-browsing capabilities (specifically Microsoft Copilot and xAI Grok) are being turned into bidirectional command-and-control (C2) proxies. By utilizing “summarization prompts” on attacker-controlled URLs, malware can receive operator commands and exfiltrate data while appearing as legitimate HTTPS traffic to an AI provider.

  • Why it Matters: This bypasses traditional network security filters that whitelist major AI domains. The AI essentially acts as a “cleansing” layer that scrubs the malicious intent from the network signal.
  • Defenses: Monitor for high-frequency, low-volume “browsing” requests from AI agents to obscure or newly registered domains. Implement prompt-injection filters that scan for encoded instructions or “jailbreak” syntax in outbound API payloads.
  • Expert Insight: “Attackers are now leveraging APIs to dynamically generate code at runtime that adapts based on information gathered from the victim’s environment.” — Check Point Research.

ClawHavoc Campaign: 12% of “ClawHub” Skills Found Malicious

A major supply-chain attack dubbed ClawHavoc has hit the OpenClaw (formerly Moltbot/Clawdbot) ecosystem. Researchers found that 12% of the skills on the popular ClawHub repository contained a “Poisoned Manifest.” When an agent reads these skills, the LLM is tricked into generating “helpful” terminal commands (e.g., curl | bash) that install the Atomic Stealer payload.

  • Why it Matters: This exploits the “semantic trust” between an agent and its skill-set. Because the agent directly interprets the manifest, it becomes a high-speed social engineering conduit to the end user.
  • Defenses: Conduct immediate audits of all installed OpenClaw skills. Disable “autonomous shell execution” for agents unless verified by a human-in-the-loop.
  • Expert Insight: “Safe operation requires treating initial findings as hypotheses… an agent that validates its own discoveries creates a single point of failure.” — Aikido Security Analysis.

Wallarm Report: APIs are the Primary Attack Surface for AI

The 2026 API ThreatStats Report reveals that 36% of all AI-related vulnerabilities in the past year involved a direct overlap with API security flaws. APIs are now the single most exploited surface in the CISA KEV dataset (43%).

  • Context for AI: Since every AI agent interaction is mediated through an API, “AI Security” is functionally becoming an “API Security” discipline. Failures in identity and access control at the API layer are the primary drivers of AI system compromise.

Dataminr: Average Monthly Threat Actor Alerts Surge 225%

Dataminr’s 2026 landscape report highlights a structural shift in risk, with a 225% increase in threat actor alerts. The report notes that AI-enhanced social engineering now accounts for the majority of observed social engineering activity.

  • Context for AI: The volume of “mega-loss” events is rising because AI allows attackers to automate the reconnaissance and credential-harvesting phases that previously required manual effort.

🌱 Emerging Signals

  • Visibility Gap: A Pentera survey of 300 CISOs found that 67% have limited visibility into how AI is actually being used in their environment, despite high adoption rates.
  • ISO 42001 Momentum: ISO 42001 (AI Management System) is reportedly appearing in Fortune 500 RFPs as a “table-stakes” requirement for 2026, forcing a shift from voluntary to mandatory AI governance.
