Source: amazon-inspector (8e42991a6cdb40d2c1dec58317f280d0a6e38ad2dfa14b1a0dfe2ac40c5dc18a)

The package ships multiple heavily obfuscated JavaScript bundles under assets/ (AccountPage, DarkVeil, GamesPage, PlusBlockedNote, SettingsPage) that use hex-prefixed identifier mangling consistent with javascript-obfuscator output. The package name presents as a backup utility, but the shipped assets appear to be a bundled web UI (account, settings, games pages) whose contents cannot be readily inspected due to the obfuscation. No install-time lifecycle hook, hardcoded network destination, credential access path, or dropper mechanism was identified in the shipped files. The mismatch between the declared name and the shipped web-app assets, combined with opaque obfuscation of user-facing code paths, reduces transparency about what the bundles do when loaded.

Source: ghsa-malware (941983b0216e3cae217e1472fd7c51d949b0ad611f39133f94d32cdd27f6dd87)

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
