Garden-Variety Cybercrooks Breached Yahoo, Says Security Firm


The hackers who stole the data of hundreds of millions of Yahoo users two years ago were two cybercriminal gangs, InfoArmor reported Wednesday. That finding contradicts the notion that state-sponsored actors were behind the attack, which Yahoo suggested earlier this month when it disclosed the breach. Further, the number of users’ records stolen is closer to 1 billion than to the 500 million Yahoo acknowledged, according to InfoArmor. However, much of the data is useless, the firm said.
