Malicious code in @dktunited/anly-tracker-v2 (npm) Remove it immediately and rotate any exposed credentials.
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 stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @dktunited/anly-tracker-v2 (version 99.99.99). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @dktunited/anly-tracker-v2 across your stack and pipelines.
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.
Did it already run?
If @dktunited/anly-tracker-v2 was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @dktunited/anly-tracker-v2 before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
