Remove it from every machine and lockfile it reached. Treat any credentials, tokens and SSH keys present on those machines as exposed and rotate them. Check CI runners and container images that installed it.
Tracked for PyPI packages. HuggingFace models declare Python dependencies, so npm packages are not covered.

// 1 advisories
GHSA-9mjp-gv34-3jcf
CRITICAL
All versions of aasync typosquatted a popular package of similar name and tracked users who had installed the incorrect package. The package uploaded information to a remote server including: name of the downloaded package, name of the intended package, the Node version and whether the process was running as sudo. There is no further compromise.
// recommendation
Remove the package from your dependencies and always ensure package names are typed correctly upon installation.
