This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 82.0% - **Started:** 2026-08-13T01:54:20.410Z - **Finished:** 2026-08-13T01:55:10.332Z - **Download time:** 504 ms - **Static scan time:** 1071 ms - **AI review time:** 48346 ms - **Total time:** 49922 ms ## Security analysis ### Published attack-surface review - **Summary:** At an explicit CLI start, the package installs/runs a persistent bridge daemon. Its MCP download tool may fall back to executing a user-skill script from agent directories. - **Trigger:** User runs claude-codex-wechat start or invokes the download\_douyin MCP tool. - **Impact:** A pre-existing untrusted local skill could run under the invoking user's privileges; no install-time attack was found. - **Evidence paths:** package.json, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-13T01:55:10.332Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent WeChat bridge plus external skill-script fallback execution. - **Rationale:** Source does not substantiate the scanner's remote decode-and-execute claim or an unconsented lifecycle attack. The external skill fallback and explicit persistence warrant a warning rather than a block. - **Files touched:** ~/.claude-codex-wechat/config.json, ~/.agents/skills/douyin-download/scripts/douyin-download.mjs, ~/.claude/skills/douyin-download/scripts/douyin-download.mjs - **Network endpoints:** https://ilinkai.weixin.qq.com, wss://wechat.style520.com/agent, https://registry.npmmirror.com/claude-codex-wechat/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Explicit CLI start installs a persistent user service., MCP tool can execute a script from ~/.agents or ~/.claude skill paths., Daemon listens on all interfaces and connects a configured relay. - **Evidence against:** No install, preinstall, or postinstall lifecycle hook., No decoded remote payload or eval/Function execution found., Network use is aligned with WeChat, relay, and update functions. ## Public findings ### 1.
