@broadpeak/smartlib-adnpm
Advisory published Updated
@broadpeak/smartlib-ad is a confirmed malicious npm package (MAL-2026-10178) that opens a backdoor for remote access (malicious version 24.1.10). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @broadpeak/smartlib-ad (npm)
What this malware does
package.json declares preinstall: node index.js, which fires automatically on npm install. index.js loads child_process/os/https, runs whoami and id, collects host identifiers (os.hostname, os.platform, os.arch, os.homedir, os.userInfo username/uid/gid/shell, os.type, os.release, process.cwd), and POSTs the collected JSON to a hardcoded Burp Collaborator (OAST) subdomain at https://3quc59n15cfcretszaygwfm9v01rphd6.oastify.com/detox56. The package ships no functional code beyond this beacon, has empty description/author, and is published under the @broadpeak scope — consistent with dependency-confusion reconnaissance impersonating an internal Broadpeak package. Installing this package leaks installer host/user identifiers to an attacker-controlled out-of-band endpoint and confirms code execution inside the target's build environment for follow-up targeting.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for @broadpeak/smartlib-ad (version 24.1.10).
If you installed it — respond
@broadpeak/smartlib-ad establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If @broadpeak/smartlib-ad 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 @broadpeak/smartlib-ad-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
