# MAL-2026-5407: Malicious code in @card-pci-data/store (npm)


- **Type:** Malicious package

## What is MAL-2026-5407?

MAL-2026-5407 is a malicious package in @card-pci-data/store, published on 9 Jun 2026. 

### 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.
