Stephen Totilo at Kotaku has a long article detailing the exploits of an Australian hacker who calls himself SuperDaE. He managed to break into networks at Microsoft, Sony, and Epic Games, from which he retrieved information about the PS4 and next-gen Xbox 'Durango' (which turned out to be correct), and he even secured developer hardware for Durango itself. He uncovered security holes at Epic, but notified the company rather than exploiting them. He claims to have done the same with Microsoft. He hasn't done any damage or facilitated piracy with the access he's had, but simply breaching the security of those companies was enough to get the U.S. FBI to convince Australian authorities to raid his house and confiscate his belongings. In an age where many tech-related 'sources' are just empty claims, a lot of this guy's information has checked out. The article describes both SuperDaE's activities and a journalist's efforts to verify his claims.
