## What is MAL-2026-6119?

MAL-2026-6119 is a malicious package in parket-helper, published on 18 Jun 2026. 

### Official description

index.js imports child_process and invokes execSync with bash and zsh shells (lines 315 and 331). Without traced reachability, it is not established whether these calls fire at install/require time, fetch external content, or process attacker-controlled input. Helper packages that shell out can be legitimate (build tooling, environment setup) or harmful (droppers, env exfiltration), and the difference depends on what those execSync calls run and when. Manual review of index.js around the cited lines is recommended to determine the trigger context and the command strings being executed.

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-2026-6119?

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