(Compilation/Sky White) according to overseas media reports, Sony has filed lawsuits against hackers, individuals and groups suspected of cracking PS3, accusing them of violating the Digital Millennium Copyright Act and the Computer Fraud and Abuse Act, as well as the implementation of various copyright infringement and binary technical specifications. In response, the hackers who were prosecuted responded quickly and claimed they were legal. Here are the details. The defendants in the Sony lawsuit included the alias "Geohot", the famous American hacker George Hotz, the hacker group Fail0verflow, and some anonymous hackers. Holtz successfully unlocked the Apple iphone before, and this time he extracted the PS3 master key in a similar way and made it public on the Internet. Fail0verflow hacker groups also released a series of cracking tools, Sony said, these cracking tools breached the PS3 protection measures, making pirated software opportunity. Sony has asked the court to issue a temporary injunction to remove all cracked tools on the web and to seal up Holtz's personal computers and other related media. Currently, Holtz's website geohot.com has been closed. On the Sony complaint, George defended himself in an interview with the BBC: "I am a staunch supporter of digital intellectual property, and I look forward to seeing a company with intellectual property that has a good sense of law." But Sony's current actions have been a disappointment to me. I've talked to lawyers and I'm relieved that Sony's behavior is completely without a legal basis. "The indicted hacker members also have a hacker team called Fail0verflow who also denies any wrongdoing. The group issued a joint statement through Yahoo, claiming that it had never condoned, supported, approved or encouraged pirated video games. But Sony is dismissive of their defence, and Sony says that while they say they do not support piracy, their work can lead to this, and if it is not stopped, there will be irreparable harm to Sony in the future. But George and Fail0verflow claimed that the reason for the eventual piracy was not in them, but because Sony currently has no ability to repair PS3 security. So in order to avoid the "irreparable harm", it is unclear how many such lawsuits the Sony will have to play against hackers.
