House of Saud's columnist and his dumb expert

"I asked a friend of mine, a Ph.D., Canadian engineer who is specialized in the security of cyber information, to clarify the saga of hacker OxOmar who went after the Israeli credit card holders and managed to penetrate an Israeli bank with the purpose to insult them. In a prompt reply, my friend told me that the hacker was not Saudi. Most probably, the hacker is an Israeli one because Israeli information security had previously accused one of its recruited employees of messing up with information...The Canadian expert argued that Iran and Hezbollah are only second to Israel in cyber war in the region. He strongly believed that OxOmar was not Saudi as preliminary information stated that the perpetrator was an Israeli soldier recruited by Hezbollah."  But how would your Canadian friend know to rule out the possibility?  Does he have a gadget that no one knows about?  (thanks Laleh)
