GHSA-jxp9-84h3-hgw4

Malicious code in tlxbnhd (npm)

Details

**Severity:** Critical

**Affected versions:** `= 0.0.1`

## Source: amazon-inspector (e415dbf226269704c2cd28b1783cf594f96880dd4688b26caf7f25a19e268237)
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.
