2013 Yahoo breach hit all 3 billion accounts
Yahoo's 2013 data breach affected all of its 3 billion user accounts — not just the 1 billion accounts as was initially disclosed in 2016, Verizon disclosed today.
- Why it matters: Hacks are not always going to be clear-cut at first disclosure, a reminder to be cautious of first accounts of breaches.
- The big picture: Earlier this year the U.S. Department of Justice charged two Russian spies and two hackers hired by Russians for the breach, marking this an important example of the U.S. government's willingness to hold foreign powers accountable for hacking.
