Summary
Malicious code in simple-date-formatter-util (npm)
Details

The package appears to be a small date-formatting utility. No credential access, no install-time or import-time network activity, no lifecycle scripts fetching remote content, no obfuscated payloads, and no destinations consistent with exfiltration or command-and-control were observed. Nothing in the shipped contents matches known supply-chain attack fingerprints (installer-secret reads, dropper patterns, silent-relay of caller data, dependency-chain lure).

Source: ghsa-malware (331277f77984c01034871b322154a0430093a1a087c2e3b48d18a4cd1c7254ac)

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.
