## What is MAL-2026-10285?

MAL-2026-10285 is a malicious package in backup1-gg, published on 13 Jul 2026. 

### Official description

The npm package backup1-gg@2.0.0 ships multiple heavily obfuscated JavaScript bundles under assets/ (AccountPage, DarkVeil, GamesPage, PlusBlockedNote, SettingsPage) using the hex-identifier pattern typical of javascript-obfuscator output. The package name suggests a backup utility but the shipped contents are front-end UI bundles (page/component chunks), which does not match the advertised purpose. No install-time lifecycle scripts, credential reads, network endpoints, or exfiltration paths were identified from the available evidence; the obfuscation itself is the only concrete signal, and obfuscation alone is not proof of malicious intent.

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.

## What should I do about MAL-2026-10285?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
