Sony says that it is investigating allegations of a cyberattack this week as different hackers have stepped up to claim responsibility for the purported hack.

While claims of attacking Sony's systems were initially made by an extortion group called RansomedVC, a different threat actor has touted themselves to be the attackers and refuted RansomedVC's claims.
