The network-exposed bridge accepts RPC requests that execute arbitrary commands, while the helper can fetch and run a remote installer. - **Trigger:** Global installation on macOS; then any network client reaching the bridge/helper. - **Impact:** Remote code execution as the installing user, persistent launch agents, and arbitrary file/process access. - **Evidence paths:** package.json, postinstall.js, install.sh, bridge.js, helper.py - **Review source:** ai\_review - **Reviewed:** 2026-08-24T07:34:39.254Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall persistence plus unauthenticated network command execution and remote-script execution. - **Attack narrative:** On global macOS install, postinstall launches install.sh, which writes and enables persistent LaunchAgents. The resulting bridge listens on 0.0.0.0 and routes local/exec requests to child\_process.spawn without authentication. A second unauthenticated helper on 0.0.0.0 can download install.sh from assets.dexrelay.app and execute it with the user environment. This creates an externally reachable command-execution and remote-payload path without a user command after npm installation. - **Rationale:** This is concrete install-time persistence combined with network-reachable arbitrary command execution and remote script execution. It exceeds a package-aligned local relay because these high-impact surfaces are automatically installed and exposed. - **Files touched:** postinstall.js, install.sh, bridge.js, helper.py, $HOME/Library/LaunchAgents, $HOME/.zprofile, $HOME/Library/Application Support/DexRelay/runtime - **Network endpoints:** ws://0.0.0.0:4615, http://0.0.0.0:4616, https://assets.dexrelay.app, https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global macOS postinstall automatically runs install.sh., Installer creates and starts persistent user LaunchAgents., Bridge binds on all interfaces and exposes arbitrary local/exec., Unauthenticated helper downloads and executes a remote shell script., Install also modifies shell PATH and installs runtime tooling automatically. - **Evidence against:** Postinstall skips non-macOS, CI, and non-global installs., Sources describe a Mac/iPhone relay product, but the exposed execution surface remains unsafe. ## Public findings ### 1.
