Those hooks can be replaced with code fetched from the vendor endpoint and send conversation and audit data to that endpoint. - **Trigger:** A user runs the package's global setup or repair command, then uses a configured AI agent. - **Impact:** A remote service can change code that runs on future agent tool calls and receive collected agent content and audit details. - **Evidence paths:** package.json, dist/index.js, hooks/guard.mjs, hooks/conversation.mjs, hooks/audit.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T13:25:22.161Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global agent-hook registration, cloud hook replacement, and cloud telemetry upload. - **Attack narrative:** The package has no automatic npm lifecycle hook, but its global setup installs command hooks into several AI-agent configurations. The hook fetches replacement JavaScript from the configured cloud endpoint and overwrites locally executed hook files. Other hooks upload cleaned conversation text and tool audit records using the local API credential. This creates persistent remote control over future agent hook execution and exposes agent activity after setup. - **Rationale:** The explicit CLI setup does not make the resulting broad agent-hook persistence, remotely supplied executable updates, and cloud collection safe. The code establishes a concrete remote-code and data-exfiltration surface across multiple agent control planes. - **Files touched:** ~/.solongate/hooks/guard.mjs, ~/.solongate/hooks/audit.mjs, ~/.solongate/hooks/shield.mjs, ~/.solongate/cloud-guard.json, ~/.claude/settings.json, ~/.codex/hooks.json, ~/.gemini/config/hooks.json, ~/.config/opencode/plugins/solongate.js - **Network endpoints:** https://api.solongate.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A globally installed hook downloads code from the cloud and atomically replaces executable hook files., The command registers executable hooks across Claude Code, Codex, Antigravity, and OpenCode control surfaces., Installed hooks send cleaned conversation text and tool audit data to the cloud using the configured API credential., The package has no npm lifecycle script; the risky behavior starts after its CLI-based global setup. - **Evidence against:** The manifest contains no preinstall, install, or postinstall script., The control-surface changes are implemented in the package CLI rather than at package installation time. ## Public findings ### 1.
