The FBI is the lead federal agency for investigating cyber attacks by criminals, overseas adversaries, and terrorists. The threat is serious?and growing. Cyber intrusions are becoming more commonplace, more dangerous, and more sophisticated. Our nation?s critical infrastructure, including both private and public sector networks, are targeted by adversaries. American companies are targeted for trade secrets and other sensitive corporate data and universities for their cutting-edge research and development. Citizens are targeted by fraudsters and identity thieves, and children are targeted by online predators. Just as the FBI transformed itself to better address the terrorist threat after the 9/11 attacks, it is undertaking a similar transformation to address the pervasive and evolving cyber threat. This means enhancing the Cyber Division?s investigative capacity to sharpen its focus on intrusions into government and private computer networks.
