Why these techniques?

SSRF in GuardDog directly enables theft of the caller's GH_TOKEN (GitHub application access token) by redirecting authenticated requests to an attacker-controlled endpoint.

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

GuardDog is a CLI tool to identify malicious PyPI packages. From 1.0.0 to 2.9.0, the programmatic remote project scanning path rewrites attacker-controlled repository URLs using a blind string replacement and then sends the caller's GitHub credentials with the resulting request.…
