# MAL-2026-10101: Malicious code in date-kit-lite (npm)


- **Type:** Malicious package

## What is MAL-2026-10101?

MAL-2026-10101 is a malicious package in date-kit-lite, published on 9 Jul 2026. 

### Official description

The package advertises itself as a lightweight date-formatting utility but its postinstall lifecycle script executes the `id` command and transmits the output (installer uid/gid/groups) to a hardcoded bare-IP endpoint at http://155.190.124.243:6788/?cmd_output=<encoded>. Delivery is attempted through three redundant transports (node http.get, curl, wget) with swallowed errors to maximize successful exfiltration. The beacon also gives the operator installer IP, User-Agent, and host identity for follow-on targeting. This behavior fires automatically on `npm install`, is entirely unrelated to the declared date-utility purpose, and uses plain HTTP to a bare IP with no legitimate justification. The package name and generic description mimic well-known date helpers (date-fns, dayjs) while the author field is a self-referential placeholder, consistent with a disguised dropper targeting incidental installers.

## What should I do about MAL-2026-10101?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
