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:** 92.0% - **Started:** 2026-07-05T08:14:17.122Z - **Finished:** 2026-07-05T08:15:28.032Z - **Download time:** 260 ms - **Static scan time:** 625 ms - **AI review time:** 70024 ms - **Total time:** 70910 ms ## Security analysis ### Published attack-surface review - **Summary:** The package is a user-started bridge that lets WeChat drive local Claude Code and Codex with permissions disabled. This is a serious dual-use agent-control capability, but source inspection did not show install-time hijack, hidden payload execution, or unrelated credential exfiltration. - **Trigger:** User runs claude-codex-wechat start, scans WeChat login, then sends messages or resume commands. - **Impact:** A configured WeChat user can cause local command/file operations through Claude/Codex and request local files be sent back over the bridge. - **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:** 2026-07-05T08:15:28.032Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote chat bridge spawning local AI CLIs with disabled approvals plus MCP file-sending tools - **Rationale:** Source inspection confirms a high-risk AI-agent remote-control bridge with disabled approvals, so it should not be marked clean. It does not meet the block threshold because activation is explicit runtime use and there is no npm install-time mutation, stealth payload, or unrelated exfiltration chain. - **Files touched:** ~/.claude-codex-wechat/config.json, ~/.claude-codex-wechat/mcp-media.json, ~/.claude/projects/\*/\*.jsonl, ~/.claude/history.jsonl, ~/Library/LaunchAgents/com.claude-codex-wechat.plist, ~/.config/systemd/user/claude-codex-wechat.service - **Network endpoints:** https://ilinkai.weixin.qq.com, wss://wechat.style520.com/agent, https://novac2c.cdn.weixin.qq.com/c2c, https://registry.npmmirror.com/claude-codex-wechat/latest, http://localhost:8787/api/channel/send-media ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** dist/server/cli.js spawns Claude with --dangerously-skip-permissions and bridge MCP config., dist/server/cli.js starts Codex app-server with sandboxPolicy disabled and approvalMode never, auto-approving command/file-change requests., dist/server/cli.js can rewrite ~/.claude session JSONL to add permissionMode:bypassPermissions when normalizing sdk-cli sessions., dist/mcp/mediaServer.js exposes MCP tools that send arbitrary local file paths to the WeChat bridge endpoint., dist/server/cli.js installs user service persistence only when the user runs start/install flow. - **Evidence against:** package.json has no preinstall/install/postinstall hook; only prepublishOnly/postpublish publish-time scripts., Dangerous behavior is aligned with README-stated purpose: WeChat remote control of local Claude/Codex sessions., Network endpoints are package-aligned WeChat/relay/update/media endpoints, not hidden exfil hosts., No eval/vm/Function or decoded remote payload execution found in inspected source., Scanner high-entropy blob is a Bootstrap icon font asset. ## Public findings ### 1.
