It can install and run downloaded desktop installers and alter a user's application directory. - **Trigger:** npm install -g @firedmosquito831/my-claude-code - **Impact:** A remote repository change can execute arbitrary commands with the installing user's permissions and modify user-level applications. - **Evidence paths:** package.json, bin/postinstall.js, bin/runtime-install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T17:27:33.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote-script execution and native installer launch - **Attack narrative:** The postinstall hook runs during a global npm installation and calls the runtime installer. That installer executes a PowerShell script fetched from a mutable raw GitHub branch or pipes a fetched shell script directly to sh. It also fetches latest-release desktop assets and runs their native installers; on macOS it replaces an application under the user's Applications directory and clears its quarantine attribute. The checksum file is fetched from the same mutable release source, so it does not establish an independent trust boundary. - **Rationale:** This package creates an automatic install-time remote code execution path from mutable external content and launches native installers. The behavior is concrete and runs with the installing user's privileges. - **Files touched:** bin/postinstall.js, bin/runtime-install.js, ~/Applications - **Network endpoints:** https://raw.githubusercontent.com/FiredMosquito831/my-claude-code/main/scripts, https://github.com/FiredMosquito831/my-claude-code/releases/latest/download ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall hook., On global installation, the hook invokes the runtime installer automatically., The installer downloads a script from a moving GitHub branch and pipes it directly to a shell., The same lifecycle path downloads and executes platform installers, including silently removing macOS quarantine. - **Evidence against:** The hook skips local installs, npx, CI, and an explicit opt-out., Desktop artifacts are checked against a SHA-256 file before being written. ## Affected versions and remediation This report applies to @firedmosquito831/my-claude-code@6.61.0. - Avoid installing @firedmosquito831/my-claude-code@6.61.0. 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.
