hyperpure-core@1.0.0

Package impersonates a Zomato internal namespace (name `hyperpure-core`, repository URL pointing to `github.com/zomato/hyperpure-core`) while shipping a 63-byte stub `index.js` that exports nothing functional. The package.json `preinstall` (and `preuninstall`) lifecycle script runs at `npm install` time and uses curl to POST the installer's `hostname -f`, `whoami`, current working directory, and the full `env` output (base64-encoded) to `http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site` over plaintext HTTP. On CI / developer machines the captured environment routinely contains credential-grade values (AWS_*, NPM_TOKEN, GH_TOKEN, CI provider secrets), so this is unambiguous installer-side credential and host-identity exfiltration. The shape (internal-name impersonation + hollow module + env-leaking preinstall + OAST out-of-band callback) is a textbook dependency-confusion attack against Zomato build infrastructure. ## Source: ossf-package-analysis (1646c4910046d5c497ba97d75067f1b566f5bfe79ba938e0b9d06eda3b2eefa3) The OpenSSF Package Analysis project identified 'hyperpure-core' @ 1.0.0 (npm) as malicious.
