What is MAL-2026-6334?
MAL-2026-6334 is a malicious package in parket-flow, published on 23 Jun 2026.
Official description
index.js imports child_process and invokes execSync with bash and zsh shells (index.js line 1, 301, 317). Without traced execution context it is not possible to determine whether these shell invocations are part of legitimate tool functionality or whether they fetch and execute attacker-controlled content. No corroborating evidence of exfiltration, credential access, network beacons, or attacker-controlled endpoints is present in what was inspected. Recommend human review of the shell command construction and any inputs they consume before allowing or blocking.
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-2026-6334?
