@birbalo/aliftech-uinpm
Advisory published Updated
@birbalo/aliftech-ui is a confirmed malicious npm package (MAL-2026-17153) that opens a backdoor for remote access (malicious version 99.9.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @birbalo/aliftech-ui (npm)
What this malware does
The npm package @birbalo/[email protected] ships a postinstall.js lifecycle script that runs automatically on npm install. The script imports the built-in os and https modules, reads os.hostname() and os.userInfo().username, and issues an HTTPS GET to https://webhook.site/539f8bb9-497a-4104-92f7-f95a77204cc2/<hostname>/<username>, transmitting installer host identifiers to a third-party inspection endpoint. The package name uses a scope that resembles an internal/organization namespace and is published at version 99.9.9 — a version-number shape consistent with dependency-confusion beacons designed to win resolution against a private package of the same name. Installing this package causes any host that runs npm install (developer workstations, CI runners) to report its hostname and login user to the attacker-controlled collector, providing reconnaissance for follow-on targeting of the affected environments.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for @birbalo/aliftech-ui (version 99.9.9).
If you installed it — respond
@birbalo/aliftech-ui 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 @birbalo/aliftech-ui 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 @birbalo/aliftech-ui-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
