Assess vulnerability of 3rd party vendors

Once a 3rd party vendor has been identified as being of interest it can be probed for vulnerabilities just like the main target would be. [1] [2]

Detection

Detectable by Common Defenses (Yes/No/Partial): No

Explanation: 3rd parties would most likely not report network scans to their partners. Target network would not know that their 3rd party partners were being used as a vector.

Difficulty for the Adversary

Easy for the Adversary (Yes/No): Yes

Explanation: The difficult part is enumerating all 3rd parties. Finding major partners would not be difficult. Significantly easier with insider knowledge. Vulnerability scanning the 3rd party networks is trivial.
