Pure flour-power. Hearty enough to carry you through lunch.
Summary
The article discusses a security vulnerability in AI agents like OpenClaw when used through messaging apps such as Slack and Telegram. The risk stems from the 'link previews' feature in these apps, which can automatically exfiltrate user data when a malicious link is received in an LLM-generated message. Unlike traditional attacks where users need to click a link, this vulnerability allows data theft automatically when previews are enabled. The article notes that OpenClaw via Telegram is exposed by default to this risk.
