The package squats the internal-looking scope @ts-internal/shared-lib on the public npm registry and runs a network beacon both during install (preinstall and postinstall hooks invoke \`node lifecycle.js\`) and on module load (index.js calls \`require('./beacon').beacon('require')\`). beacon.js collects \`os.hostname()\`, \`os.userInfo().username\`, \`process.cwd()\`, \`os.platform()\`, and the package name/version, hex-encodes...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package squats the internal-looking scope @ts-internal/shared-lib on the public npm registry and runs a network beacon both during install (preinstall and postinstall hooks invoke \`node lifecycle.js\`) and on module load (index.js calls \`require('./beacon').beacon('require')\`). beacon.js collects \`os.hostname()\`, \`os.userInfo().username\`, \`process.cwd()\`, \`os.platform()\`, and the package name/version, hex-encodes the blob, and transmits it via DNS lookup and HTTPS GET to \`d8oa6q03t3o2ksbjirogwxiwiyhp6e57o.oast.site\` (an interactsh OAST collector) and \`npm-dc-seek-1781572474.testingboxes.com\`. Any build that misresolves this name to the public registry will silently leak identifying host metadata to two third-party endpoints. The README self-describes the package as a dependency-confusion proof-of-concept, but installers cannot consent and cannot verify researcher authorization; the squat-plus-beacon mechanism is the attack regardless of stated intent.
