The OpenClaw skills marketplace has turned into a conduit for malware distribution and credential theft. Description of the Problem Free Access to the System Agents are able to run shell commands without any security restrictions. Not configured Administrator Interfaces Admin interfaces that are publicly accessible without authentication Rapid Injection Attacks Attacks that deceive systems into disclosing private information Out of 3,000 ClawHub skill samples, roughly 336 malicious plugins were uploaded, indicating a 10.8% infection rate, according to the OpenClaw advisory.

These malicious skills used ClickFix social engineering techniques to deploy stealers that exfiltrate cryptocurrency wallet data, macOS Keychain credentials, browser passwords, and cloud service tokens while posing as trading bots and financial assistants. Version 2026 of Beyond Anthropic Integration.2.17 offers significant enhancements to automation workflows and messaging platforms.

The release includes improved subagent spawning capabilities through deterministic chat commands, native single-message text streaming for Slack with customizable draft preview modes, and iOS share extension functionality for direct content forwarding. URL allowlists for web search and fetch tools, cron job webhook delivery with usage telemetry tracking, and enhancements to Discord interactive components with reusable buttons and per-button user access controls are among the other features.
