Reuters story highlights more details about our discovery.
The business of recovering stolen credentials is not as simple as it would seem. We have set records before, initially with the Adobe user database including 153 million records, then with 360 million recovered in February 2014, and finally with 1.2 billion credentials in the most substantial breach known to-date. Today, large amounts of stolen credentials may not grab headlines, but they never lose their potency, especially when they are recovered by the good guys and returned to the rightful owners.
