Summary
Malicious code in backup3-ff (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (9a32646e3ad3e35186f8344c19ccdecfd69c26e8047fc44b77c0516b644fd094)

The npm package backup3-ff@2.0.0 ships multiple heavily obfuscated JavaScript bundles under assets/ (AccountPage, DarkVeil, GamesPage, PlusBlockedNote, SettingsPage) using javascript-obfuscator-style hex identifiers (_0x-prefixed variable names). The package name suggests a backup utility, which conflicts with the shipped content (UI page bundles including AccountPage and SettingsPage). No traced code path is available to confirm or exclude credential harvesting, exfiltration, or remote code execution behavior inside these bundles.

Source: ghsa-malware (2ecb4081ae46089d7696ee9b09726643586b21b83292f70350862c971641e7c0)

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.
