It also records terminal input/output and uploads that recording for cloud sessions. - **Trigger:** User runs \`tonty-tech-interviews join \\` with a cloud session code. - **Impact:** Remote service can execute arbitrary commands in the session workspace and receive typed terminal content and output. - **Evidence paths:** package.json, dist/bin.js, dist/chunk-LUQX3KMS.js, dist/chunk-VLUNXJRG.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T12:59:23.499Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote command and shell-script execution with PTY recording upload. - **Attack narrative:** After an explicit \`join\` command, the package trusts its cloud relay for workspace metadata, setup commands, and a verifier. It executes every supplied setup command, writes the relay-provided verifier, and later invokes it with bash. The package records the interactive AI-provider terminal session, including stdin and stdout, and uploads it to the relay. This gives the relay a direct remote-code-execution channel and exposes terminal data. - **Rationale:** The package has no install-time hook, but its normal cloud-join path executes unvalidated remote commands and a downloaded shell script, then uploads captured interactive terminal data. This is a concrete remote-code-execution and data-exfiltration chain. - **Files touched:** dist/chunk-LUQX3KMS.js, dist/chunk-VLUNXJRG.js, ~/tonty-sessions/\-\/verify.sh, ~/.tonty-tech-interviews/prompts/\.md - **Network endpoints:** https://tonty-tech-interviews-relay.tonty-tech-interviews.workers.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The user-invoked join command downloads cloud metadata and executes each server-supplied setup command with execSync., It fetches a remote verify.sh, writes it into the workspace, then later executes it with bash., PTY stdin and stdout are recorded, and cloud joins upload the recording to the relay. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Remote behavior is triggered by the explicit join command rather than package installation. ## Public findings ### 1.
