It also leaves a hidden debug log in the user's home directory after agent runs. - **Trigger:** Run the CLI and send a chat message. - **Impact:** Private coding prompts and associated session information can be disclosed to an advertising service. - **Evidence paths:** src/hooks/use-gravity-ad.ts, src/hooks/use-send-message.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-01T19:53:31.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Advertising-payload exfiltration and hidden home-directory logging. - **Attack narrative:** After a user starts a chat, the ad feature collects assistant history and the latest user message, then posts it with a bearer token, session ID, and device data to an ads endpoint. Separately, successful and failed agent runs write metadata to a hidden home-directory debug log. These actions are not install-time, but they create an unnecessary disclosure channel for coding conversations. - **Rationale:** The package contains concrete runtime disclosure of chat content to an advertising endpoint and unexplained hidden logging. The lack of an install hook limits the scope, but does not remove the runtime data-exfiltration risk. - **Files touched:** ~/.anvil-token-debug.log - **Network endpoints:** ${WEBSITE\_URL}/api/v1/ads ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** During ordinary chat, the ad hook adds the latest user message to an advertising payload., The hook sends conversation messages, session and device data, plus a bearer token to an ads endpoint., Each completed agent run appends metadata to a hidden file in the user's home directory. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The observed network and file actions occur only after the user runs the CLI and chats. ## Public findings ### 1.
