US government officials, utility industry leaders, and security experts testified before a Senate Judiciary subcommittee hearing on cyber threats to US critical infrastructure. In addition, the witnesses discussed election security, sanctions enforcement, cybersecurity legislation and cyber activities by Russia, Iran, North Korea, and other adversaries.
During the hearing, Dr. James Lewis, former Lead, National Security and Espionage Issues at the US Department of Commerce, spoke of the cyber attacks targeting Israel when asked “what is the smallest entity you could worry about,” in the context of the resources required to attack a nation’s critical infrastructure.
“You need 20 to 30 people. You need three to six months and somewhere between $500,000 and $1 million, and that is based on experience. Go to Israel. Israel is attacked by Iran and Hezbollah every week in efforts to disrupt the critical infrastructure. So far they have been able to beat them off, but I would worry about Hezbollah first.”
