Prompts, code context, secrets pasted into chats, and subagent transcripts can be sent to the package author's remote endpoint without clear README disclosure. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.16.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms a concrete AI-agent control-surface mutation that exfiltrates agent transcripts to a hardcoded remote endpoint without clear user-facing disclosure in README. Lack of npm lifecycle execution lowers immediacy but does not remove the malicious data-exfiltration behavior once the documented CLI is used. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-07-01T23:40:32.385Z - **Finished:** 2026-07-01T23:41:29.276Z - **Download time:** 1011 ms - **Static scan time:** 632 ms - **AI review time:** 55247 ms - **Total time:** 56891 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:** The package scaffolds AI-agent hooks that silently upload Claude/Cursor session transcripts and subagent transcripts to a hardcoded remote IP. The behavior is installed into generated agent control-surface config during explicit init/sync, not npm install. - **Trigger:** User runs refact-os init or refact-os sync, then Claude Code or Cursor fires Stop/SessionEnd/stop hooks. - **Impact:** Prompts, code context, secrets pasted into chats, and subagent transcripts can be sent to the package author's remote endpoint without clear README disclosure. - **Evidence paths:** templates/base/agent/hooks/claude-transcript-send-to-remote.py, templates/base/agent/hooks/transcript-send-to-remote.py, templates/base/agent/claude-hooks.json, templates/base/agent/hooks.json, lib/adapters.js, lib/scaffold.js, bin/refact-os.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-01T23:41:29.276Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent transcript exfiltration via generated hooks - **Attack narrative:** After a user explicitly scaffolds a project, refact-os copies transcript upload hooks into generated Claude/Cursor adapter directories and wires them into agent stop/session-end events. When those hooks run, they read local AI transcript JSONL files plus subagent transcripts and POST them to a hardcoded remote endpoint, with certificate verification disabled and failures hidden in logs. - **Rationale:** Direct source inspection confirms a concrete AI-agent control-surface mutation that exfiltrates agent transcripts to a hardcoded remote endpoint without clear user-facing disclosure in README. Lack of npm lifecycle execution lowers immediacy but does not remove the malicious data-exfiltration behavior once the documented CLI is used. - **Files touched:** agent/hooks/claude-transcript-send-to-remote.py, agent/hooks/transcript-send-to-remote.py, .claude/hooks/claude-transcript-send-to-remote.py, .cursor/hooks/transcript-send-to-remote.py, .claude/settings.json, .cursor/hooks.json, .cursor/logs/cursor-upload-transcript.log, .claude/logs/claude-upload-transcript.log - **Network endpoints:** https://159.223.97.72:8443/transcript ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** templates/base/agent/hooks/claude-transcript-send-to-remote.py reads Claude transcript\_path and subagent JSONL transcripts., templates/base/agent/hooks/transcript-send-to-remote.py reads Cursor transcript\_path and subagent JSONL transcripts., Both transcript hooks POST full transcript JSON to default https://159.223.97.72:8443/transcript with TLS verification disabled., templates/base/agent/claude-hooks.json wires claude-transcript-send-to-remote.py into Stop and SessionEnd hooks., templates/base/agent/hooks.json wires transcript-send-to-remote.py into Cursor stop hooks., lib/adapters.js generates .claude/settings.json and .cursor/hooks.json from those hook specs during init/sync. - **Evidence against:** package.json has no install/postinstall lifecycle hook; scaffolding is user-invoked via bin/refact-os.js., bin/refact-os.js only runs main when invoked directly, not on require()., bin/refact-os.js refuses root, home, parent-of-home, and package-root targets., templates/packs/wordpress/agent/skills/plugin-update/scripts/fetch-changelog.mjs fetches public WordPress changelog data or user-configured SSH fallback, not confirmed exfiltration., templates/packs/seo/agent/skills/ga4/scripts/google-login.mjs is an explicit OAuth helper saving tokens to 1Password. ## Affected versions and remediation This report applies to @refactco/refact-os@2.16.0. - Avoid installing @refactco/refact-os@2.16.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
