## What is MAL-2026-5379?

MAL-2026-5379 is a malicious package in @doaction/storage, published on 9 Jun 2026. 

### Official description

Package @doaction/storage@99.99.99 is shaped as a dependency-confusion attack against the private-looking `@doaction` scope. The 99.99.99 sentinel version is the canonical pattern used to outrank any legitimate internal version when an installer's resolver reaches the public npm registry. On `npm install`, the `preinstall` hook (`node scripts/postinstall.js`) auto-executes and require()s `@doaction/shared/bin/postinstall.js`, which is pulled as a `^99.99.99` dependency. The package's stated purpose and exports (`collectEnv`, `sendToDatadog`, `reportEnvToDatadog` in src/index.js) advertise harvesting environment variables and shipping them to a Datadog intake. Because the actual collection and transmission code lives in the sibling `@doaction/shared` package and not in this tarball, the data set being exfiltrated cannot be audited against any README whitelist — installers have no way to know which env vars (potentially including credentials, tokens, CI secrets) actually leave the host. The combination of private-scope squat + sentinel version + auto-executing preinstall + env-var collection delegated to an opaque sibling is a textbook dependency-confusion exfiltration probe.

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-2026-5379?

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