@azure-growth/signup-ux-components@1.2.2
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe manifest activates the code automatically, and the source shows identifying host data sent to a fixed external collector through DNS. This is an installation beacon and supports blocking publication.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package when its preinstall hook runs.
Impact
The external domain can receive identifying information about the installing machine and observe the installer's DNS egress.
Mechanism
index.js builds a DNS name containing the username and hostname, then resolves it.
Attack narrative
During package installation, the preinstall hook runs index.js. That code reads the local username and hostname, embeds both in a DNS query to a fixed OAST domain, and performs the lookup without a consent guard.
AI rationale
The manifest activates the code automatically, and the source shows identifying host data sent to a fixed external collector through DNS. This is an installation beacon and supports blocking publication.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs index.js automatically during preinstall.
- index.js collects the local username and hostname and embeds them in a DNS name under a fixed OAST domain.
- The preinstall code resolves that name, sending the identifying values to the external domain.
