Description
The npm package checkout-format-money version 35.8.6 contains malicious code that executes a remote code execution dropper upon being required. It reconstructs attacker-controlled hostnames, downloads a binary payload, writes it to disk with disguised filenames, sets executable permissions, and runs it detached with the installer's privileges. This behavior confirms hostile intent and poses a severe risk to any environment that installs and uses this package.
