The former CEOs of Yahoo and Equifax — companies which were hit with two of the biggest data breaches of all time — will be probed by senators on Wednesday about the state of America's cybersecurity defenses.
Yahoo revealed last month that every account — 3 billion in all — was affected by a 2013 data breach. The revelation built on previous disclosures that more than 1 billion accounts were hacked. Hackers stole email addresses, passwords, birth dates, telephone numbers and more in the attack, but did not access passwords in clear text, payment card data or information about bank accounts.
Two Russian intelligence agents and two other people have been indicted in connection with the attack of at least 500 million Yahoo accounts.
