TalkTalk Telecom CEO Dido Harding has confirmed personally receiving ransom demand following a hacker attack this week that may have exposed sensitive data on all four million of the companys customers. Data from the breach was posted publicly Friday though it is not clear yet whether the dump represents the entirety of what was stolen or just a small portion of it. This is the third time this year that the publicly traded TalkTalk has been hit in a cyber attack. Many have slammed TalkTalk for not protecting its data better considering that the company has been breached just this year.”]
