Hacker accused of infecting 900,000 Deutsche Telekom routers with an altered version of Mirai malware pleaded guilty on Friday. The 29 year-old’s identity has not been revealed, but he is occasionally referred to as Spiderman or Popopret. Before the Mirai attack, he was behind the GovRAT malware that hacked a number of US agencies, authorities said. He has also been linked to attacks on British internet service providers Post Office and TalkTalk. An independent investigation by security researcher Brian Krebs claims the hacker BestBuy is in fact a man named Daniel Kay, linked to a large family in Israel.”]
