The correct answer is B. Poorly implemented autoupdates allowed for an evilgrade attack. The evilgrade tool offers many software packages to subvert, and it only requires that the attacker's response is accepted by the target, so if some DNS attack has gotten the software searching for updates to go to the malware server, it will download and install on its own.
