tlxbnhdnpm
Advisory published Updated
tlxbnhd is a confirmed malicious npm package (MAL-2026-16385) that executes malicious code on install (malicious version 0.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in tlxbnhd (npm)
What this malware does
The tlxbnhd package ships obfuscated preinstall.js and postinstall.js lifecycle scripts that, on npm install, download two files from https://api.imghippo.com/files/hOG8244hc.png (an anonymous image-hosting URL disguised with a.png extension), write them into the package directory as gldriver_pre_core.exe and gldriver_pre_asset.exe, and launch them using platform-specific commands (start on Windows, open on macOS, xdg-open/mspaint on Linux). After launch the scripts unlink the dropped files to remove traces. The URLs, filenames, and shell commands are hidden inside an obfuscator.io-style rotating string array with an index-shifting IIFE. The same dropper runs from both preinstall and postinstall, so it executes twice per install.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for tlxbnhd (version 0.0.1).
If you installed it — respond
Remove tlxbnhd 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 tlxbnhd 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 tlxbnhd-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.
