Meet the Lebanese hacker that calls himself(we thinks its a He) “Idahc”(His twitter account avi above), He says It began as “justice,” then it became a “Game”, and he says now he is actually trying to make the web more “Secure”, “I did this to push Sony to pay more attention on their security and to show everyone that I.T security is fundamental,” he writes to me in an email. “I don’t hack for ‘lulz’ but for moral reasons.” (#StopIt5)
an 18-year old Lebanese computer science student, working from a “poor Internet connection” and a laptop, hiding his identity with the usual tricks such as VPNs and proxy servers that disguise his origin, as well as hacking into his neighbor’s network. From that humble setup, he’s managed to evade arrest while hacking Sony three times, most recently compromising a database of Sony Portugal users last Thursday by exploiting three different types of Web vulnerabilities on one page: A cross-site scripting flaw, a SQL injection, and an iFrame injection.
