Surprisingly to some, three suspects of the hacker attack perpetrated upon Sony earlier this year in April have been arrested in Spain by the local police. Even though it’s nice for Sony to put a face on the crime, it might be in their best interest to keep their guard up. The hacker group, which goes by the name of Anonymous, had publicly taken responsibility of the attack. Sony did not make any comments, stating that they don’t usually disclose any remarks or information on cases that are still undergoing investigation. Therefore, it is not yet known if Sony had any involvement at all in recognizing the suspects that have been arrested. Almost immediately after the story broke, websites, forums and chat rooms that are a commonplace for the hacker group started to spill out threats. One blog akin with the group posted a photo of the film V for Vendetta.  Through their usual way of threat communication, Twitter, Anonymous tweeted: “We are Legion, expect us”. Hacker networks are usually so large, that by arresting a few members the core of the group still remains untouched. That is one of the reasons why Sony should remain expectant, and in this case even wait for a reprisal attack. In addition to Anonymous, there has been an increase in the formation of networks of groups that favor what they call ‘hacktivism’. In regards to the act of hacking, there's evidence that these networks are developing a system in order to work more efficiently. This makes them a lot more dangerous than they once were, since new groups or networks are popping out every month or two. Taking a look back just a couple of months, the following entities have been targets of hacking: PBS, Google, Infragard, Acer, RSA, Citibank, the Government of Turkey and the well known attacks on the Church of Scientology, Amazon.com and MasterCard. Of course, all of these attacks were separate from each other. Perhaps Sony was the worst since the hackers got a hold of the financial information of millions of gamers. Reports say that the company underwent 20 separate attacks in a period of a few months. Many have stated that the reason why Sony is such an easy target is due to the fact that its Web security seems to be inferior to other companies in the industry. Another group, Lulzsec, had already stolen 150,000 pieces of information from Sony, and proceeded to publish them in order to mock the company's fragile security. As a matter of fact, the group tweeted that the information it took -- such as passwords -- was available in plain text. Other companies usually encrypt confidential information as such, which in case that it gets stolen, is not easily read. At this point, Sony should consider revamping its method of operation as well as its security system in order to stop the current long-line of cyber attacks. Source: WSJ
