Chat & Ask AI exposed approximately 300 million chat messages Jan 20; reported Feb 9, 2026

A researcher found that a Firebase security misconfiguration in the Chat & Ask AI app exposed an estimated 300 million messages associated with more than 25 million users. The exposed material reportedly included users’ chat histories, files, and settings. The developer reportedly corrected the configuration after disclosure; public reporting did not establish that an outside party had accessed the data before remediation.

Security takeaway: Treat Firebase rules and other cloud database access policies as production security controls. Test access from an unauthenticated account and verify that private records cannot be read or modified.

Hundreds of malicious skills targeted OpenClaw users Jan 27; reported Feb 2026

Security researchers reported hundreds of malicious skills on ClawHub, the community marketplace for the OpenClaw personal AI agent. Many were disguised as crypto-related tools or utilities and delivered information-stealing malware to the host computer when installed. This was a supply-chain risk: users could trust a skill because it appeared in an agent ecosystem, even though its code was malicious.

Security takeaway: Treat agent skills, plugins, MCP servers, and extensions like executable third-party software. Review source code, restrict filesystem and credential access, and do not install untrusted skills on machines containing sensitive data.

AI-assisted attacker compromised more than 600 FortiGate firewalls Jan 11–Feb 18; reported Feb 2026

Amazon reported a campaign in which a Russian-speaking threat actor compromised more than 600 FortiGate devices across 55 countries. The attacker reportedly targeted internet-exposed management interfaces and weak passwords without multifactor authentication, then used generative AI to help develop scripts, plan reconnaissance, and analyze stolen network configuration data. Amazon described AI as an amplifier; weak credentials and exposed management services were key entry points.

Security takeaway: Remove firewall management interfaces from public exposure, enforce MFA and unique strong credentials, patch devices, monitor authentication attempts, and protect VPN and backup infrastructure.

AI-assisted intrusion reportedly stole Mexican government data Late 2025–Jan 2026; reported Feb 25

Reporting cited by OWASP described an intrusion affecting Mexican government agencies, including tax and electoral entities. Attackers reportedly used Claude and, at times, ChatGPT to assist reconnaissance, script generation, and exploit development; reporting estimated that roughly 150 GB of tax and voter data was exposed or stolen. The incident is evidence of AI being used to accelerate an intrusion, not evidence that an AI model independently carried out the operation.

Security takeaway: Prioritize internet-facing application patching, credential hardening, network segmentation, logging of automated reconnaissance, and data-loss monitoring for sensitive government or citizen records.

Meta’s internal AI-agent advice led to a temporary data-access exposure Reported Mar 20, 2026

The Guardian reported that an employee implemented advice from an internal AI agent that inadvertently made sensitive user and company data accessible to a wider group of employees for about two hours. Meta said user data was not mishandled. The event was described as an internal access-control incident caused by an unsafe recommendation and human implementation, rather than an external attacker stealing data.

Security takeaway: Do not let AI-generated recommendations directly change permissions or data visibility without independent review, automated policy checks, and a tested rollback path.

OpenAI’s macOS app-signing workflow encountered a malicious Axios package Mar 31; disclosed Apr 11, 2026

A malicious Axios package ran during OpenAI’s macOS application-signing workflow after a GitHub Actions workflow relied on a floating package reference rather than a fixed commit. OpenAI treated its signing certificates as potentially compromised, rotated them, and worked with Apple to block notarization using the old certificate. OpenAI said it found no evidence that user data, internal systems, or production software had been compromised. The event occurred on March 31 but was publicly disclosed in April, so it is included here by occurrence date.

Security takeaway: Pin CI/CD dependencies to immutable versions or commit hashes, enforce provenance and package-age checks, isolate signing credentials, and rotate secrets promptly when a build pipeline may have executed malicious code.

Defensive Checklist: AI Systems and Agents

• Verify AI package provenance, dependency integrity, and container image digests.
• Use least-privilege, short-lived credentials for AI agents and connected tools.
• Keep agent control planes private and require strong authentication.
• Sandbox execution and restrict access to internal networks, files, and secrets.
• Treat prompts, traces, telemetry, and tool outputs as potentially sensitive data.
• Log agent activity and require approval for high-impact actions.
• Clearly distinguish confirmed facts, preliminary estimates, and unverified claims.
