“It is doubtless the attacker had been focusing on Kronos for a while previous to the detonation of the ransomware,” Mellen mentioned. Till we all know when and the way the preliminary penetration occurred, it is protected to imagine Kronos Non-public Cloud clients could have had delicate information stolen and react accordingly.
