Whoever hacked Sony's databases have left a taunting message for the electronics giant, according to a report from the Wall Street Journal.
In a letter to Congress which was just released today, Sony said that while the hacker(s) covered up all traces of their attack, Sony had discovered a file left on their servers called "Anonymous," and within it was the tag line "We Are Legion."
Anonymous have denied any relations to this attack, as has George "GeoHot" Hotz, although Anonymous suggested that individuals from the group may or may not have been involved.
"Whether those who participated in the denial-of-services attacks were conspirators or whether they were simply duped into providing cover for a very clever thief, we may never know," Sony said.
Sony have been under intense pressure from the international crowd, with Congress demanding answers, a US and Canadian law firm are now suing for compensation. Fund managers believe that Sir Howard Stringer should step down after the fiasco, thus affecting Kazuo Hirai's chances of succeeding the 69 year old CEO and chairman.
As a side note, this does not necessarily mean Anonymous is behind it. For all we know, the hacker may have left the message in order to use Anonymous as a scapegoat.
