It can invoke privileged package-manager commands and create user desktop/font artifacts. - **Trigger:** npm postinstall (\`node cli.js --install\`) - **Impact:** A package install can execute changing remote payloads and alter the host before the user runs \`bmo\`. - **Evidence paths:** package.json, cli.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:52:03.841Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented lifecycle remote-code bootstrap and system mutation - **Attack narrative:** npm installation triggers cli.js. It fetches and extracts an unpinned GitHub main-branch archive, then conditionally pipes remote opencode and Ollama installers to shells, uses OS package managers (including sudo) and pip, and writes desktop/font artifacts. The fetched application is subsequently executed by the bmo command, so a later remote-branch change can become local code execution without a package version change. - **Rationale:** The behavior is explicit rather than stealthy, but it is still an unconsented postinstall remote-code bootstrap with broad host mutation and no content pinning or verification. This meets the firewall block threshold for concrete install-time execution risk. - **Files touched:** dist/, $HOME/.opencode/bin, $HOME/.local/share/fonts/Blue Water.otf, $HOME/Library/Fonts/Blue Water.otf, $XDG\_DESKTOP\_DIR/bmo.desktop - **Network endpoints:** https://github.com/lmdelm-dev/bmo/archive/refs/heads/main.tar.gz, https://opencode.ai/install, https://opencode.ai/install.ps1, https://ollama.com/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node cli.js --install\` at postinstall., cli.js downloads the mutable GitHub \`main\` tarball into \`dist/\` without integrity verification., Postinstall invokes remote installers through \`curl | bash\` for opencode and Ollama., Postinstall runs privileged OS package-manager commands and user-level pip installs., cli.js creates a desktop launcher and installs a font in user directories. - **Evidence against:** No credential harvesting, secret reads, or exfiltration code found., No obfuscation, eval, dynamic JavaScript loading, or host-fingerprinting gate found., Commands and persistence are openly described in README.md. ## Public findings ### 1.
