The initializer then enumerates /mnt/c/Users to locate a Windows profile and writes an env-setup.cmd launcher into the Windows Startup folder (AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup) so the dropped executable auto-runs on every Windows logon, escaping the WSL sandbox. All identifiers, URLs, filesystem paths, and the.cmd template are stored as String.fromCharCode numeric arrays to defeat static inspection. The fetched binaries are unpinned, unverified, and unrelated to the stated purpose.\n\n## Source: ghsa-malware (0407492842053bc7b7100ba1c547c1ed50f16d289a43fd4e0345e35ce7c0d8f0)\nAny computer that has this package installed or running should be considered fully compromised.
