MAL-2026-11059 Malicious code in pp-react-ui5 (npm)

Analysis of [email protected] (4 files) surfaced no behaviors matching supply-chain attack classes: no lifecycle scripts fetching or executing remote content, no reads of installer credential paths (~/.npmrc, ~/.aws, ~/.ssh, browser profiles), no environment-variable scraping, no hardcoded exfiltration endpoints, no obfuscated payloads, and no backdoor or silent-relay mechanisms observed. The package appears benign under the criteria evaluated here.

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.

The OpenSSF Package Analysis project identified 'pp-react-ui5' @ 28.0.0 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
