The record-breaking Yahoo breach wasn’t perpetrated by nation-state attackers, as Yahoo has claimed, but rather by a group of “professional blackhats from Eastern Europe” who are also suspected of stealing and reselling customer data from LinkedIn, MySpace and Tumblr, according to a new report from the security firm InfoArmor (see Yahoo Breach: The Great ‘Nation-State’ Cop Out).
Yahoo didn’t immediately respond to a request for comment on the InfoArmor report.
