Yigal Unna, the head of the Israel National Cyber Directorate, issued a cryptic warning “Cyber winter is coming” in the aftermath of Iranian attack on the Israeli water utility infrastructure. Allegedly Israel has retaliated by paralysing Shahid Rajaee, a key Iranian port port. Many tend to believe that Yigal Unna’s warning was addressed to Israeli cyberforce defending national critical infrastructure. I tend to believe that he meant something different – cyber winter is coming to Iran. No mercy for mullahs trying to put Israeli population into harm’s way.
