amdocs-core-packagenpm
Advisory published Updated
amdocs-core-package is a confirmed malicious npm package (MAL-2025-6695) that executes malicious code on install (malicious version 11.11.11). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in amdocs-core-package (npm)
What this malware does
The package communicates with a domain associated with malicious activity.
The package declares a preinstall hook that runs index.js on npm install. index.js requires https and os, reads os.hostname(), and issues an https.request POST to a hardcoded *.oastify.com Burp Collaborator subdomain, additionally embedding the hostname into the DNS label of that subdomain for out-of-band capture. Package metadata is placeholder (empty description and author, version 11.11.11, name shaped like an internal 'amdocs' scope), consistent with a dependency-confusion payload targeting an internal namespace. Installing the package causes the installer's host identifier to leave the machine to an attacker-controlled collaborator domain.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for amdocs-core-package (version 11.11.11).
If you installed it — respond
Remove amdocs-core-package from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If amdocs-core-package 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 amdocs-core-package-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
