AI Security Review
scanned 4mo ago · by lpm-firewall-aiSource inspection confirms user-level persistence, remote command execution, and arbitrary path upload behavior that is not limited to benign package functionality. The absence of npm lifecycle hooks reduces install-time blast radius but does not mitigate the malicious runtime payload.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs the bin CLI runtimedev-link with token/env configuration.
Impact
Remote operator can maintain user-level persistence, run shell commands, inventory the host, and exfiltrate files/directories from accessible paths.
Mechanism
persistent C2 agent with remote command execution and file exfiltration
Attack narrative
Running the CLI loads token/env configuration, writes persistence files, and starts a polling loop to the configured API. After activation, the server can send commands for shell execution, directory scan requests, and file download requests; results are posted back with host identity and telemetry.
AI rationale
Source inspection confirms user-level persistence, remote command execution, and arbitrary path upload behavior that is not limited to benign package functionality. The absence of npm lifecycle hooks reduces install-time blast radius but does not mitigate the malicious runtime payload.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- bin/cli.js runs installPersistence() during normal CLI startup, not only explicit install.
- lib/persistence.js registers autostart via systemd user units, crontab, launchd, or Windows Task Scheduler.
- lib/transport.js polls /api/telemetry/poll-command and executes server-supplied commands through lib/exec.js execSync.
- lib/download.js zips arbitrary requested file/directory paths and lib/transport.js posts them to /api/telemetry/upload-download.
- lib/transport.js reports hostname, username, OS info, directory tree, public IP, and Chrome extension inventory.
Evidence against
- package.json has no npm lifecycle scripts, so install alone does not execute code.
- Network API base is supplied by token or environment rather than hardcoded, except api.ipify.org for public IP lookup.
