No authentication is required before the bridge dispatches local/exec. - **Trigger:** npm global install on macOS, followed by a WebSocket request to the started bridge. - **Impact:** A reachable peer can run arbitrary commands with the installing user's privileges and retain access through LaunchAgents. - **Evidence paths:** package.json, postinstall.js, install.sh, bridge.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T07:05:26.169Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall persistence plus unauthenticated remote command execution - **Attack narrative:** On global macOS installation, postinstall launches install.sh. The installer writes and starts persistent LaunchAgents, including a bridge configured on 0.0.0.0:4615. Any connecting WebSocket client reaches the local RPC dispatcher; local/exec passes its command array directly to spawn without an authentication or peer-authorization check. This creates a concrete remote command-execution path as the installing user. - **Rationale:** The lifecycle-triggered installer creates persistence and starts a LAN-exposed bridge whose local/exec handler runs supplied commands without authorization. This is concrete attack behavior, not merely a package-aligned setup primitive. - **Files touched:** postinstall.js, install.sh, bridge.js, $HOME/Library/LaunchAgents/com.codexrelay.bootstrap.plist, $HOME/Library/Application Support/DexRelay/runtime - **Network endpoints:** 0.0.0.0:4615 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global macOS postinstall invokes install.sh automatically., Installer creates and starts persistent user LaunchAgents., Bridge listens on all interfaces and accepts WebSocket clients., Unauthenticated local/exec spawns caller-supplied commands. - **Evidence against:** Postinstall skips non-macOS, CI, and non-global installs., Claude sign-in RPCs have a separate trusted-transport check. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 6. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 7. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 8. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** servicectl.py - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```python path = servicectl.py kind = build_helper sizeBytes = 13291 magicHex = [redacted] ``` ### 9. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 95.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** postinstall.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = dexrelay@0.1.73 matchedPath = postinstall.js matchedIdentity = npm:ZGV4cmVsYXk:0.1.73 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 11. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** bridge.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = dexrelay@0.1.70 matchedIdentity = npm:ZGV4cmVsYXk:0.1.70 similarity = 0.833 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** postinstall.js - **Public source:** [View source]() Global macOS postinstall invokes install.sh automatically. Public source snippet (untrusted): ```javascript async function main() { if (shouldSkipAutoInstall()) { process.exit(0); } const installScript = path.join(__dirname, "install.sh"); const startTime = Date.now(); log("Installing the DexRelay Mac runtime. This usually takes 20-40 seconds."); log("Do not interrupt this step even if npm looks quiet for a moment."); const child = spawn("bash", [installScript], { cwd: __dirname, stdio: ["ignore", "pipe", "pipe"], env: { ...process.env, CODEX_RELAY_AUTO_INSTALL: "1", CODEX_RELAY_INSTALL_MODE: "npm[redacted]", HOMEBREW_NO_AUTO_UPDATE: process ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 2 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 2 ### Published dependency entries - qrcode-terminal ^0.12.0 (Dependency) - ws ^8.19.0 (Dependency) ## Package metadata - **Package:** dexrelay - **Ecosystem:** npm - **Version:** 0.1.75 - **License:** MIT - **Version published:** 2026-08-24T07:01:18.872Z - **Package first seen:** 2026-07-15T19:47:29.942Z - **Package last seen:** 2026-08-24T07:34:39.254Z - **Known versions:** 4 - **Latest version:** 0.1.77 - **Appeal under review:** No - **Description:** Mac-side CLI/bootstrap runtime for the DexRelay iPhone app. - **Author:** DexRelay - **Keywords:** dexrelay, codex, mac, ios, cli, bootstrap - **Artifact files:** 33 - **Artifact unpacked size:** 1,350,689 bytes - **Artifact signatures:** 1 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
