The hackers, alternatively, dispute this characterization. They instructed Motherboard that they may be able to certainly get admission to electronic mail contents and feature proven that newsletter screenshots to end up their level. Additionally they declare that the hack lasted a minimum of six months, doubling the duration of vulnerability that Microsoft has claimed. After this pushback, Microsoft replied that round 6 p.c of shoppers suffering from the hack had suffered unauthorized get admission to to their emails and that those shoppers won other breach notifications to make this transparent.
