# MAL-2026-12506: Malicious code in @latlongid/location (npm) - **Type:** Malicious package - **Package:** `@latlongid/location` (npm) - **Published:** 5 Aug 2026 ## What is MAL-2026-12506? MAL-2026-12506 is a malicious package in @latlongid/location, published on 5 Aug 2026. ### Official description @latlongid/location@1.0.1 declares `postinstall: node index.js` in package.json, so `index.js` runs automatically on every `npm install`. That script hex-encodes the installer's `os.hostname()` and embeds it as a subdomain of `dns.gl0b.xyz`, then invokes `dns.lookup` on the constructed name (e.g. `2d5bccee-...-h..dns.gl0b.xyz`). The DNS query name itself carries the host identifier off the machine, so exfiltration succeeds regardless of resolution result. The scoped name and generic 'internal utility' metadata are consistent with a dependency-confusion reconnaissance beacon designed to enumerate reachable internal build environments. ## What should I do about MAL-2026-12506? Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed. ## Fix prompt for AI coding agents ```text MAL-2026-12506 is a malicious package: @latlongid/location (npm).
