Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to clipboard-guardian@1.0.3. The same advisory and Firewall decision cover these 4 recorded versions: 1.0.0, 1.0.1, 1.0.2, 1.0.3. - Avoid installing clipboard-guardian@1.0.3. 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. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% This package is a cryptocurrency clipper masquerading as a clipboard-protection tool. Its postinstall script (npm-install.cjs) writes 30+ hardcoded attacker-controlled wallet addresses (ETH 0x450c0E58Fc2ba03632d3F5780ad8C966648B6F18, BTC bc1qs2mpls4p0f7fng073gy2rcdgjpf7la4eugpt6y, Monero 42zhAidVhP7QETk83JAspS59ASALSHFio44vmu6..., and addresses for ~30 other chains) into the package's config.json, then installs and auto-starts a bundled Python daemon (clipboard\_guardian/guardian.py) that monitors the system clipboard and silently replaces any cryptocurrency address the user copies with the attacker's address — rerouting outgoing crypto transfers to the attacker. The postinstall installs system-wide persistence under deceptive names that impersonate OS components: a systemd unit named \`python3-dbus-helper.service\` on Linux (with \`loginctl enable-linger\` for boot persistence), a LaunchAgent \`com.apple.python.runtime.plist\` on macOS, and a Task Scheduler entry \`PyRuntimeBroker\` on Windows. To support deployment, the script invokes \`apt-get\`/\`pacman\`/\`dnf\` to install python3-pip, downloads bootstrap.pypa.io/get-pip.py, runs \`pip install --break-system-packages\`, and uses SUDO\_USER/\`sudo -u\`/\`su -l\` for privilege juggling. The runtime daemon includes anti-analysis logic: it enumerates running processes and pauses address replacement when forensic tooling (Process Explorer, Process Hacker, Process Monitor, htop, btop, Activity Monitor, gnome-system-monitor, ksysguard, taskmgr.exe) is detected, and renames its own process via setproctitle/SetConsoleTitleW to match the impersonated OS component names. All postinstall status loggers (info/ok/warn) are stubbed to no-ops so that the privileged multi-step install produces no terminal output, hiding the activity from a casual \`npm install\` observer. The README's cover story claims the package defends against clipboard-hijacking — it implements the attack it claims to prevent. \#\# Source: ossf-package-analysis (594054a5de1b58c5ed2cdd11d2a561b1733798ed39ef0268b80a926a8007e1c3) The OpenSSF Package Analysis project identified 'clipboard-guardian' @ 1.0.0 (npm) as malicious.
