date-kit-litenpm
Advisory published Updated
date-kit-lite is a confirmed malicious npm package (MAL-2026-10101) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in date-kit-lite (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for date-kit-lite (version 1.0.0).
If you installed it — respond
date-kit-lite 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 date-kit-lite 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.

Detect & block this
O3 blocks date-kit-lite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
