customerdigital-ui-containers-libnpm
Advisory published Updated
customerdigital-ui-containers-lib is a confirmed malicious npm package (MAL-2026-4543) that steals credentials and exfiltrates sensitive data (malicious versions 99.12.9, 99.13.9, 99.14.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in customerdigital-ui-containers-lib (npm)
What this malware does
On npm install, postinstall.js collects git identity, OS user/uid, hostname, internal network interface addresses, Cloudflare Pages environment variables, and directory listings of ~/.ssh, ~/.aws, and /.kube (first 5 entries of each), base64-encodes the payload, and sends it as a query string via an HTTPS GET to ho9skv69a3pbqzbzg7z1l009c0ir6hu6.oastify.com — a Burp Collaborator out-of-band exfiltration host. The script also implements explicit sandbox evasion: it returns early if the current working directory starts with /tmp, contains 'npm-', or HOME is unset, with a 'Diagnostic/2.0' User-Agent cover story. The targeted directories (/.ssh, ~/.aws, ~/.kube) reveal credential filenames (id_rsa, credentials, config) suitable for follow-on targeted theft. The package name shape and dependency-confusion-style high version (99.12.9) are consistent with an internal-name squat reconnaissance payload.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
The OpenSSF Package Analysis project identified 'customerdigital-ui-containers-lib' @ 99.13.9 (npm) as malicious.
It is considered malicious because:
- The package communicates with a domain associated with malicious activity.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for customerdigital-ui-containers-lib (3 malicious versions).
If you installed it — respond
customerdigital-ui-containers-lib 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 customerdigital-ui-containers-lib 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 customerdigital-ui-containers-lib-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
