Official description
On
npm install, the package's preinstall hook (scripts.preinstall: node index.js || true) runs index.js which collects host identity — os.hostname(), os.userInfo().username, __dirname, and process.cwd() — and exfiltrates it through two channels: (1) an HTTP POST to the hardcoded bare IP 172.201.213.59:9090/c, and (2) a DNS resolution of a hex-encoded label appended to *.d8jbmnsqcfu78dfs8vdg34ohqhirb4pbg.oast.live (an interactsh-style out-of-band beacon). The package has no advertised functionality beyond this beacon; its description is security research and the scoped name @card-pci-data/store impersonates payment-card / PCI-related tooling, consistent with a dependency-confusion or namespace-abuse lure. This auto-executes on default install and produces clear attacker benefit (installer host fingerprint delivered to attacker-controlled infrastructure).What should I do about MAL-2026-5407?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
