MAL-2026-2866 Malicious code in @tableau__catalog-messages/database_lower (npm)

The package contains two files and no static or traced indicators of installer-side harm. No lifecycle scripts fetching or executing remote content, no reads of installer secret paths (such as ~/.aws, ~/.ssh, ~/.npmrc), no environment-variable scraping, no hardcoded attacker destinations, and no silent-relay or backdoor mechanisms were observed. The scope and name shape are consistent with an internal/staging Tableau publication rather than attack infrastructure.

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 '@tableau__catalog-messages/database_lower' @ 99.9.9 (npm) as malicious.

It is considered malicious because:

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