Execution
Both embedded a malicious prerequisite block that directed agents to a paste-site redirect lure at rentry[.]co/openclaw-code, where a Base64-encoded command waited to be run in a terminal window.
Base64-encoded curl-pipe-bash dropper: These skills embedded a fake prerequisite block that instructed the agent to decode and execute a Base64-encoded remote payload...
OpenClaw is an AI agent that runs third-party skills sourced from ClawHub, a dedicated marketplace. These skills are markdown-driven packages with deep access to local systems. When a malicious skill is installed, it can seize full control of the agent’s identity and execute unauthorized actions through the agent’s own authenticated sessions.

Command and Control
Infostealers: Two skills delivered macOS infostealers. Both connect to command-and-control (C2) infrastructure... Alternative exfiltration channel: A distinct cluster... exfiltrated cryptocurrency private keys via the Telegram Bot API, a C2 channel independent of the shared dropper infrastructure.

A macOS infostealer delivered via malicious OpenClaw marketplace skills, retrieved from remote infrastructure and used to steal data from compromised environments.
A macOS infostealer fetched from attacker infrastructure via a paste-site redirect and Base64-decoded command execution chain in malicious ClawHub skills. It connects to C2 infrastructure and follows the same delivery template as earlier ClawHavoc-style campaigns.
