“Although many are asking the question, was this a cyber-attack or physical sabotage, the answer could be ‘both.’ The most likely suspects are the U.S. and Israel working in tandem. Both countries have very sophisticated cyber warfare units and significant capabilities when it comes to cyber-kinetic attacks,” explained David Kennedy, CEO of TrustedSec and a former NSA and Marine Corps cyber-intelligence expert. “An attack of this magnitude would require a great deal of planning and preparation, and is very complex because you are exploiting industrial control systems and air-gapped devices.”
