It can also install current desktop release artifacts and alter user application locations. - **Trigger:** npm install -g @firedmosquito831/my-claude-code - **Impact:** A repository or release change can execute arbitrary code on the installing machine and modify user-level software. - **Evidence paths:** package.json, bin/postinstall.js, bin/runtime-install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T08:19:54.428Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote script execution and latest-release artifact installation - **Attack narrative:** The postinstall hook runs during global installation and calls the runtime installer. That installer constructs commands that download a script from the repository's mutable main branch and immediately executes it through sh or PowerShell with execution-policy bypass. It also downloads artifacts from the mutable latest release and runs platform installers. The package snapshot therefore does not contain the code ultimately executed at install time. - **Rationale:** This is an automatic lifecycle-driven remote code execution chain with broad machine mutation. Checksum verification of artifacts does not protect the separately piped remote script or pin either source to an immutable trusted version. - **Files touched:** bin/postinstall.js, bin/runtime-install.js, ~/Applications/\, global npm bin/my-claude-code - **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:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package registers a postinstall lifecycle hook., On every global installation, the hook invokes the runtime installer., The installer fetches a mutable GitHub raw script and pipes it directly into a shell or PowerShell with execution-policy bypass., It also downloads latest-release desktop artifacts and executes, mounts, or unpacks them automatically., The installer fetches a mutable GitHub raw shell script and pipes it directly to sh. - **Evidence against:** The postinstall hook skips local installs, CI, and explicit opt-out cases., Desktop artifacts are checked against a checksum file before local execution, but both come from the mutable latest release. ## Affected versions and remediation This report applies to @firedmosquito831/my-claude-code@6.78.0. - Avoid installing @firedmosquito831/my-claude-code@6.78.0. 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.
