Summary: Malicious code in pp-react-v5 (npm)

Details: `pp-react-v5` is a dependency confusion package published at the inflated version `10.0.0` to win npm resolution over any internally-hosted package of the same name. The package contains only a `package.json` with no functional source code. On installation the `preinstall` script executes a `wget` command that sends a GET request to `http://q9ou9xtw.requestrepo.com/` with the current username (`whoami`), working directory (`pwd`), and hostname as query parameters, beaconing the victim machine's identity to the attacker-controlled endpoint. Source: amazon-inspector (f2ada661adc926404648a9955aaad5c4faefaf24937ec8a75df2deaf0f09716c) package.json declares preinstall and postinstall hooks that execute index.js on npm install. The script collects installer host identifiers via os.hostname(), os.userInfo().username, os.homedir(), process.cwd(), dns.getServers(), and the local package.json contents, then POSTs them over HTTPS to a hardcoded interact.sh out-of-band collector subdomain at bvfmpadujgjgmbtzeibi1n3vi1psox11k.oast.fun. The package name 'pp-react-v5', the description 'Internal App bUg b0UntY gollum22 h1', and the inflated 30.0.1 version are consistent with a dependency-confusion probe targeting an internal package name. Installing this package results in unauthenticated disclosure of installer identity, environment, and repository metadata to an attacker-controlled collector. Source: ossf-package-analysis (b2291adfbdded958f2fa2a51aa5e582d8ec4bad5bb1c5c9b614bd496732c3578) The OpenSSF Package Analysis project identified 'pp-react-v5' @ 10.0.0 (npm) as malicious. It is considered malicious because: - The package executes one or more commands associated with malicious behavior.
