The list of compromised information “may have included” things like names, email addresses, telephone numbers, dates of birth, encrypted passwords, “and, in some cases,” security questions and answers. The statement notes that the security questions and answers may be “encrypted or unencrypted,” which isn’t exactly helpful information, but thankfully, the hack does not appear to include “unprotected passwords, payment card data, or bank account information.”
The announcement comes almost two months after Motherboard initially reported that hackers were offering up “200 million” Yahoo accounts on the “dark web.” Yahoo didn’t confirm it until now, though. As of this writing, there have been no reports as to who the “state-sponsored actor” is, but it would appear to be code for Russia or maybe China based on other recent major hacks.
