Malicious code in node-stack-frames (npm)

Details

**Severity:** Critical

**Affected versions:** `= 4.0.0`

package.json declares a preinstall script that runs an inline Node program on `npm install`. The script requires `os` and `http`, collects `os.hostname()`, `os.platform()`, and `os.arch()`, base64-encodes the result, and issues an HTTP GET to `https://d8lslmi9io6i264ftj80mh9e7niqiaenf.oast.live/?data=<encoded>`. The host is a Project Discovery interactsh (OAST) subdomain used as an out-of-band collection endpoint. The package ships no functional code — its own description identifies it as a security holding placeholder — so the only effect of installing it is the automatic exfiltration of installer host identifiers to an attacker-controlled collector. This matches a dependency-confusion / recon beacon pattern.
