A pure and powerful JavaScript Kaspa library for building blockchain applications
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package entrypoint performs automatic, unrelated hostname disclosure through DNS on import. This is a concrete data-exfiltration behavior, so blocking publication is warranted.
Static reason
No blocking static signals were detected.
Trigger
A consumer imports lib/index.js.
Impact
The query discloses a machine identifier to a package-selected endpoint without a consent check.
Mechanism
A timer runs after five seconds, reads part of the machine hostname, hex-encodes it, and uses it as a DNS query label.
Attack narrative
Importing the package schedules a DNS lookup. The lookup includes a hex-encoded prefix of the machine hostname at v1.kaspacore-lib.io, disclosing a machine identifier without a consent check.
AI rationale
The package entrypoint performs automatic, unrelated hostname disclosure through DNS on import. This is a concrete data-exfiltration behavior, so blocking publication is warranted.

Evidence for block
- package.json selects lib/index.js as the package entrypoint.
- Importing the entrypoint schedules an automatic callback after five seconds.
- The callback encodes part of the machine hostname as a DNS query label and sends a lookup to v1.kaspacore-lib.io without a consent check.
