What this malware does

scripts/postinstall.js runs unconditionally during npm install and exfiltrates installer-side identifiers to an attacker-controlled out-of-band collector. The script fetches the installer's public IP from api.ipify.org, then collects os.userInfo().username, os.hostname(), process.cwd(), the package name, and the resolved IP, and transmits them to the hardcoded host xjaipnfhcpawuhzlgzkzub8mc0rqdiuyp.oast.fun (an Interactsh OOB collector) via two channels: a dns.lookup of a hex-encoded subdomain and an https.request to /poc carrying the JSON payload base64-encoded in an x-poc header. The package is published at version 99.99.99 — the canonical dependency-confusion squat marker designed to outrank any internal @dktunited/anly-tracker-v2 package by semver. Whether labeled a bug-bounty PoC by the author or not, it is live on the public registry and will harm any build system that resolves it.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @dktunited/anly-tracker-v2 (version 99.99.99).

  2. If you installed it — respond

    @dktunited/anly-tracker-v2 is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If @dktunited/anly-tracker-v2 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. @dktunited/anly-tracker-v2 on npm has been identified as a malicious package (version 99.99.99 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
