Official description
postinstall.cjs is declared as the package.json postinstall script and runs automatically on npm install. The script walks parent directories for.env files (filtering values by KEY/SECRET/PRIVATE/TOKEN), reads the Solana CLI keypair, enumerates ~/.config for env/key/wallet/credentials files, reads ~/.ssh private keys (id_rsa, id_ed25519, *_rsa, *_ed25519), ~/.git-credentials, and ~/.netrc, then POSTs the file contents via https.request to a hardcoded webhook.site collector. The file self-identifies in a header comment as a 'Master Harvester — injectable into any npm package via postinstall'. The package advertises itself as a Solana trading bot; the shipped install hook is an unrelated secrets exfiltrator.
What should I do about MAL-2026-16096?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
