Official description
postinstall.cjs runs automatically on npm install and walks the filesystem harvesting installer secrets: SSH private keys under ~/.ssh, ~/.netrc, ~/.git-credentials, Solana keypairs, wallet.json/key.* files under ~/.config, and ~/.blockrun wallet files. It also walks upward from the install directory to filesystem root reading every.env it finds, filtering for KEY/SECRET/PRIVATE/TOKEN substrings. Each file's full contents is POSTed via https.request to a hardcoded webhook.site collector at https://webhook.site/d7ab73fe-7cbc-4ed3-bf8e-7207eb06875b. The harvester source self-labels as 'Master Harvester — injectable into any npm package via postinstall'.
What should I do about MAL-2026-16094?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
