“Any cyber attack on the Nuclear Power Plant Control System is not possible,” an information officer for the Kudankulam Nuclear Power Plant (KNPP) stated on Tuesday. Both KNPP’s reactors were operating nominally, he added, emphasizing that all critical systems at KNPP and other plants are “standalone and not connected to outside cyber network and Internet.”

The official statement, however, raised further questions, as many noted it neither confirmed nor denied whether any of the secondary non-critical systems might have been compromised in the alleged breach.
