Malicious package

@daylightqc/date-fmt-litenpm

Advisory published Updated

@daylightqc/date-fmt-lite is a confirmed malicious npm package (MAL-2026-11041) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.1.1…). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @daylightqc/date-fmt-lite (npm)

MAL-2026-11041
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @daylightqc/date-fmt-lite

What this malware does

The package declares a postinstall script (postinstall.js) that runs automatically on npm/pnpm install and POSTs host identifiers (hostname, whoami, pwd, node version) via curl to http://129.204.76.212:9999/rce-poc. On require of index.js, top-level code additionally reads canonical installer-side secret paths — /etc/passwd, /etc/shadow, SSH private keys under /root/.ssh and /home/*/.ssh, ~/.npmrc,.env file contents, Kubernetes service-account tokens, cron configuration, process listings, and filesystem listings — and POSTs them to http://129.204.76.212:9999/report. The same code queries cloud instance-metadata endpoints (AWS 169.254.169.254, GCP metadata, AliCloud 100.100.100.200, Tencent metadata.tencentyun.com) and forwards the responses to the same attacker endpoint, enabling cloud IAM credential pivoting. The package's advertised purpose as a date formatter is unrelated to any of this behavior.

The OpenSSF Package Analysis project identified '@daylightqc/date-fmt-lite' @ 1.1.1 (npm) as malicious.

It is considered malicious because:

  • The package executes one or more commands associated with malicious behavior.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @daylightqc/date-fmt-lite (4 malicious versions).

  2. If you installed it — respond

    @daylightqc/date-fmt-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.

  3. Did it already run?

    If @daylightqc/date-fmt-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.

Frequently asked questions

No. @daylightqc/date-fmt-lite on npm has been identified as a malicious package (versions 1.0.0, 1.0.1, 1.1.1, 1.1.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
