## Public findings

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

tempo-modules@99.0.1 is a dependency-confusion attack package. The package.json preinstall hook executes poc.js, which on every \`npm install\` harvests hostname, username, full network configuration (ipconfig/ip a/resolv.conf), git remote, parent package.json, and CI pipeline definitions (.gitlab-ci.yml,.github/workflows, Jenkinsfile, azure-pipelines.yml), plus whoami/id output. It then iterates process.env and selects any key containing TOKEN, AWS, AZURE, NPM, GITHUB, GITLAB, CI, JENKINS, BUILD, WALMART, etc. — bulk credential scraping of cloud and CI tokens. The collected JSON is POSTed to https://d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me/\<pkg\> (an Interactsh out-of-band collector), with a hex-encoded host-user identifier additionally DNS-exfiltrated. The package is published at version 99.0.1 with an internal-sounding name to win dependency-confusion resolution against an organization's private registry; the description self-identifies as a 'Dependency Confusion PoC' for a bug-bounty program, but the published artifact harms any installer that resolves this name. Multiple independent block signals stack: lifecycle preinstall outbound exfil, bulk credential harvest of CI/cloud tokens, and dependency-confusion version inflation.
