An explicit CLI start registers a package-owned background daemon and connects it to a WeChat relay. Incoming authorized chat activity can invoke the package's configured local Claude/Codex bridge, creating a deliberate remote agent-control capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-07-10T12:58:08.647Z - **Finished:** 2026-07-10T12:59:41.800Z - **Download time:** 251 ms - **Static scan time:** 1326 ms - **AI review time:** 91575 ms - **Total time:** 93153 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit CLI start registers a package-owned background daemon and connects it to a WeChat relay. Incoming authorized chat activity can invoke the package's configured local Claude/Codex bridge, creating a deliberate remote agent-control capability. - **Trigger:** User runs \`claude-codex-wechat start\` and configures/authorizes the bridge. - **Impact:** A compromised or misconfigured WeChat/relay identity could cause local agent actions through the configured provider. - **Evidence paths:** package.json, README.md, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-10T12:59:41.800Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked persistent WeChat-to-local-agent bridge. - **Rationale:** No concrete malicious chain or unconsented lifecycle mutation was found. The explicit persistent remote AI-agent control surface remains a meaningful dual-use risk and warrants a warning. - **Files touched:** dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs, ~/.claude-codex-wechat/config.json, ~/Library/LaunchAgents/com.claude-codex-wechat.plist, ~/.config/systemd/user/claude-codex-wechat.service - **Network endpoints:** https://ilinkai.weixin.qq.com, https://novac2c.cdn.weixin.qq.com/c2c, wss://wechat.style520.com/agent, https://registry.npmmirror.com/claude-codex-wechat/latest, https://www.iesdouyin.com, https://aweme.snssdk.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`dist/server/cli.js\` makes \`start\` install a launchd/systemd user service when absent., The daemon bridges WeChat/relay messages to local Claude/Codex provider commands., \`dist/mcp/mediaServer.js\` exposes MCP file/media sending and runs only bundled \`douyin-download.mjs\` via \`execFile\`., Remote media is AES-decrypted then saved as media; no decoded payload execution was found. - **Evidence against:** \`package.json\` has no preinstall/install/postinstall hook; \`prepublishOnly\` only builds before publishing., Service persistence is reached by explicit \`claude-codex-wechat start\`, not installation or import., No \`eval\`, \`Function\`, VM execution, dynamic remote module loading, or remote code staging was found., Network use is package-aligned: WeChat login/media, configured relay, update registry, and explicit Douyin download. ## Public findings ### 1.
