Reigning Miss Teen USA has told of the terrifying moment she opened an email that featured naked photographs of herself secretly taken via webcam from a hacker at her school. Cassidy Wolf's interview with Anderson Cooper comes as an international crackdown by the FBI and police in 19 countries has brought more than 90 arrests in what authorities say is a serious strike against 'creepware'. Wolf, 19, had been watched for one year by former classmate Jared Abrahams, who had installed Blackshades malware on her laptop and was jailed in March for hacking women. Cassidy Wolf, 19, speaks with Anderson Cooper about her 'sextortion' ordeal on Monday night, after her computer was hacked and a boy from her school secretly watched her via webcam for one year. Wolf was sent an email containing a series of photos of herself changing, with Abrahams demanding better-quality photos, video and a five-minute sex show on Skype or he would make the images public, threatening to ruin her beauty pageant chances.
