cilm-ui-commonsnpm
Advisory published Updated
cilm-ui-commons is a confirmed malicious npm package (MAL-2026-13943) that steals credentials and exfiltrates sensitive data (malicious version 1.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in cilm-ui-commons (npm)
What this malware does
On npm install, the preinstall hook executes index.js which collects host identity data (os.hostname(), os.userInfo().username, os.homedir(), current working directory, DNS server list) together with the full package.json contents and POSTs them to the hardcoded external endpoint https://eogo57c0daum9d3.m.pipedream.net. The behavior fires unconditionally at install time on every installer machine. A code comment references burpcollaborator/Interactsh-style beaconing, consistent with dependency-confusion reconnaissance: the beacon fires when a private internal package name is inadvertently resolved from the public npm registry, revealing the victim's internal infrastructure to whoever controls the pipedream endpoint. The exfiltrated fields identify the installer's host, user account, filesystem layout, network DNS configuration, and internal package/dependency graph.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for cilm-ui-commons (version 1.1.0).
If you installed it — respond
cilm-ui-commons 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 cilm-ui-commons 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 cilm-ui-commons-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
