Epsilon Breach Used Four-month-old Attack

The letters from Chase and Citi, both say effectively: "your data was stolen, here's what you should do to protect your data." They then go into a litany of minor data hygiene practices, failing to point out they themselves did not vet their vendor's security practices. There is no claim of culpability for bad security policy nor any indication that they will try to do better in the future. In other words, no reason why you should trust them with your data (and this response is sadly commonplace).
