Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 22 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.2.67 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. An explicit cloud-session join accepts remote setup commands and executes them locally. The same flow downloads a shell verifier and remote AI instructions, and later uploads recorded agent-session data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-21T18:39:36.620Z - **Finished:** 2026-08-21T18:40:49.437Z - **Download time:** 510 ms - **Static scan time:** 1277 ms - **AI review time:** 71029 ms - **Total time:** 72817 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An explicit cloud-session join accepts remote setup commands and executes them locally. The same flow downloads a shell verifier and remote AI instructions, and later uploads recorded agent-session data. - **Trigger:** User runs tonty-tech-interviews join with a cloud session code. - **Impact:** A relay or session author can obtain code execution in the joined workspace and receive recorded session content. - **Evidence paths:** package.json, dist/bin.js, dist/chunk-YHWFQKTK.js, dist/chunk-VLUNXJRG.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T18:40:49.437Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote session payload drives local shell execution and AI-agent instructions. - **Rationale:** The package's risky behavior is user-invoked and aligned with its interview-platform purpose, so source does not establish stealthy malicious intent. However, untrusted remote session fields directly reach shell execution and the relay receives recorded session data. - **Files touched:** ~/.tonty-sessions/, ~/.tonty-tech-interviews/prompts/, verify.sh - **Network endpoints:** https://tonty-tech-interviews-relay.tonty-tech-interviews.workers.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** Cloud join fetches session-controlled metadata and passes setupCommands to a shell executor., A cloud response can supply verify.sh, which is later executed with bash., Cloud sessions upload captured agent-terminal events and session results to the Tonty relay., Remote session content is written as AI-provider instructions. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The risky paths require an explicit CLI join command and session code., Tar extraction checks absolute and traversal paths; no stealth install-time behavior was found. ## Affected versions and remediation This report applies to tonty-tech-interviews@0.2.67. - Review the evidence and your use of tonty-tech-interviews@0.2.67 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
