## What is MAL-2026-5371?

MAL-2026-5371 is a malicious package in @doaction/example, published on 9 Jun 2026. 

### Official description

@doaction/example@99.99.99 is a scoped npm package whose package.json self-describes as 'Example package with Datadog environment telemetry for internal testing' and pins `@doaction/shared` at `^99.99.99`. On install, scripts/preinstall.js delegates execution to `@doaction/shared/bin/preinstall.js` via `require('@doaction/shared/bin/preinstall.js')`. The shared dependency's preinstall code is not present in this tarball and its actual behavior cannot be confirmed from the contents shipped here. The library API `reportExampleEnv` (src/index.js) is opt-in: callers must explicitly supply a Datadog API key and invoke the function, and the documented whitelist is limited to `EXAMPLE_MODE` and `EXAMPLE_DEBUG`. The installer-facing risk depends entirely on what `@doaction/shared`'s preinstall and `collectEnv` actually do — those bytes need to be reviewed before a final disposition. The 99.99.99 version pattern combined with the scoped name is also consistent with a dependency-confusion shape against an internal `@doaction` namespace, which warrants human assessment.

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-2026-5371?

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