Advisory published Updated

dbk-ui-forms is a confirmed malicious npm package (MAL-2026-12669) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in dbk-ui-forms (npm)

MAL-2026-12669
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall dbk-ui-forms

What this malware does

On npm install, the package's preinstall hook runs index.js which collects host identity (hostname, username, homedir, network interfaces, uid), output of whoami/id/pwd/uname -a, and the names of process.env variables matching a broad credential regex (key/token/secret/pass/auth/cred/npm/ci/build/jenkins/github/gitlab/aws/azure). The collected JSON is transmitted to the hardcoded Interactsh subdomain ycwyyoimdcluajepubah2mvmkibt4h5wm.oast.fun via HTTPS POST, HTTP POST, and DNS-encoded lookups. The package name and version (99.0.1) are consistent with a dependency-confusion beacon targeting internal build systems that resolve an unclaimed name from the public registry.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for dbk-ui-forms (2 malicious versions).

  2. If you installed it — respond

    dbk-ui-forms 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 dbk-ui-forms 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. dbk-ui-forms on npm has been identified as a malicious package (versions 99.0.0, 99.0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks dbk-ui-forms-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
