“New York Investigates Deloitte Cyberbreach,” The Wall Street Journal, October 13, 2017 B10. New York AG investigates breach, which “compromised information on a small number of clients.” The breach started a year ago and wasn’t detected until April 2017. The information compromised may have been limited to access credentials and the like, rather than account information. Sort of like Equifax.
Who else has been attacked and (a) knows about it but is still keeping it quiet, or (b) doesn’t know about it yet?
