The US Department of Justice has revealed the identity of a hacker who is thought to be responsible for hundreds of attacks on US and Israeli state networks. Ehud Tenebaum, an Israeli teenager has been named as the culprit following an extensive operation in the US involving around 30 FBI officers, the Department of Justice, the Air Force Office of Special Investigations, NASA, the Naval Criminal Investigative Service, and finally the Israeli Ministry of Justice. The investigation first came to light when the homes of two Californian teenagers were searched after it was discovered they were connected with the attacks. Tenebaum has now been arrested by Israeli Police for illegally accessing computers owned by the Israeli and US Governments, as well as hundreds of commercial and educational institutions in the US. According to reports, although the US is treating the attacks as serious, no classified material was accessed during the attacks.
