The global cyberwar is heating up and the stakes are no longer limited to the virtual world of computers. With leading defense experts and investigative journalists who have probed the murky realm of criminal and strategic hacking, NOVA looks into the chilling new reality of cyberwar in which no nation or individual is safe from attack. Kim Zetter, senior staff writer for Wired, joined Dakota Midday Tuesday. She was interviewed for NOVA's "Cyberwar Threat," which premieres Wednesday night at 8:00 p.m. Central on SDPB-TV. Zetter is also the author of COUNTDOWN TO ZERO DAY: Stuxnet and the Launch of the World's First Digital Weapon.
