> How is this one individual responsible for tracking all IT security vulnerabilities in all the technologies that equifax uses across its stack? How do they not have an admin team whose job it is to do these things?

They do have a vulnerability management team; the responsibility does not fall on one person.

For all we know this unnamed individual is just a low-level developer, analyst or pentester who had some knowledge of the exposure and failed to act.
