Classification

Malicious package

Published to npm · OSV MAL-2026-12506

What to do

Remove @latlongid/location from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package @latlongid/location version 1.0.1 contains malicious code that executes automatically upon installation. The postinstall script runs a JavaScript file that encodes the installer's hostname and sends it as part of a DNS query to an external domain, effectively exfiltrating host identification data. This behavior is consistent with reconnaissance activity aimed at identifying internal build environments, potentially for dependency confusion attacks.

Impact

The malicious code exfiltrates the hostname of the machine installing the package by embedding it in DNS queries to an attacker-controlled domain. This can reveal internal host identifiers and potentially expose internal network topology or build environments. While no direct code execution beyond the postinstall script is described, the information leakage can facilitate further targeted attacks such as dependency confusion or supply chain compromise.

Defensive guidance

Users should avoid installing @latlongid/location@1.0.1 and remove it from their dependency trees if present. Consider auditing dependencies for malicious postinstall scripts and restrict installation of untrusted or unknown npm packages. Monitor for updates or advisories from the package maintainers or npm registry regarding remediation.

Summary

@latlongid/location@1.0.1 declares a postinstall script in its package.json that runs index.js automatically on every npm install. The script hex-encodes the installer's os.hostname() and constructs a DNS query name embedding this encoded hostname as a subdomain of dns.gl0b.xyz. It then performs a dns.lookup on this constructed name, leaking the host identifier via the DNS query regardless of resolution success. This technique aligns with a dependency-confusion reconnaissance beacon designed to enumerate internal build environments accessible from the compromised machine.
