Immediate action

npm uninstall @aspect-adv-ui/consent-manager

What this malware does

@aspect-adv-ui/consent-manager 2.4.1 declares a postinstall hook (node setup.js) that fires automatically on every npm install. setup.js issues an HTTPS GET to a hardcoded webhook.site inspection endpoint (https://webhook.site/kapper), sending install-event metadata (source IP, TLS/user-agent fingerprint) to an author-controlled third-party collector. The package is advertised as a small GDPR/CCPA consent-bar React component with no native build, no binary, and no legitimate install-time work; the postinstall exists solely to run this beacon. webhook.site is a public request-inspection service commonly used as an anonymous exfiltration/beacon endpoint, and the beacon is not disclosed or opt-in.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @aspect-adv-ui/consent-manager (2 malicious versions).

  2. If you installed it — respond

    @aspect-adv-ui/consent-manager 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 @aspect-adv-ui/consent-manager 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. @aspect-adv-ui/consent-manager on npm has been identified as a malicious package (versions 2.4.0, 2.4.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
