While U.S. military leaders appeared before Congress to outline their strategy to fight Islamic State militants on the battlefield, the National Security Agency chief said on Tuesday he was watching the media-savvy group's cybercapabilities.
Asked whether the Sunni Muslim group was planning cyberattacks on U.S. interests, Adm. Mike Rogers said he could not discuss specifics of the organization's technical capabilities.
"We need to assume that there will be a cyber dimension increasingly in almost any scenario that we're dealing with," Rogers said at a cybersecurity conference in Washington.
