AI Security Review

scanned 2h ago · by lpm-firewall-ai

Installation automatically executes an obfuscated setup script that mutates the consuming project. The networked token exchange appears confined to an explicit setup/auth path rather than the postinstall call.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install @fleetbo/svro

Impact

Creates and rewrites development configuration and package metadata without an explicit command.

Mechanism

obfuscated postinstall project-configuration mutation

Rationale

This is an unconsented install hook that broadly changes the host project and is unnecessarily obfuscated. Source inspection does not establish theft, remote payload execution, or AI-agent-control hijacking, so a warning is proportionate rather than a block.

OpenSSF Malicious Packages via OSV

Summary

Malicious code in @fleetbo/svro (npm)

Details

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for block

package.json runs dist/postinstall.cjs automatically on install.
dist/postinstall.cjs is deliberately obfuscated and writes project files.
Postinstall creates/changes svro.schema.json, tsconfig/jsconfig, Vite config, and package.json.
dist/postinstall.cjs has an HTTPS token request to bootstrap...a.run.app, but its auth/env path is not invoked by postinstall.

Evidence against

No confirmed credential harvesting or exfiltration in the install-time path.
No AI-agent configuration/control-surface writes found.
README.md describes the configuration mutations, though automatic execution is excessive.
