How many exposed OpenClaw instances have been reported?
Reports cite 42,000, 65,000, 40,000, and 30,000 exposed instances across various analyses, highlighting risks from insecure dashboards and lack of isolation in self-hosted deployments.
What real-world attacks have targeted OpenClaw agents?
Attacks include phishing tests tricking email agents into leaking credentials, multimodal hidden instruction attacks, malicious plugins with data exfiltration, and the first documented autonomous AI cyberattack exploiting unauthenticated shells.
How are companies like Nvidia and Microsoft addressing OpenClaw security?
Nvidia and ServiceNow are building sandboxed OpenClaw-style agents, while Microsoft announced Windows agent security with MXC and OpenShell at Build 2026, including policy-based containment and integration with Purview for data protection.
What research supports the need for better OpenClaw isolation?
Japanese security papers show 0% pass rates for ambiguous instructions and agent-to-agent attacks, while Varonis and MalSkillBench research confirm persistent prompt injection and supply chain risks even with security instructions or detectors.
