The Washington Post said on May 19 that the recent cyberattack against an Iranian port was carried out by Israel in retaliation for Iran's cyberattack against Israel's national water infrastructure, and, as reported by Israel Defense on May 15, is part of a new cyber war between the two countries.
According to the report, computers controlling the flow of trucks, goods and vessels at Shahid Rajaee terminal all crashed simultaneously on May 9, creating enormous backups of vehicle and shipping traffic. The terminal is located in the city of Bandar Abbas on the strategic Strait of Hormuz.
Intelligence sources were reported to have said that the assault was carried out by Israeli cyber actors. A foreign defense source, speaking on the condition of anonymity, was quoted as saying the attack was highly precise and caused much more serious damage than what Iran has admitted.
Dmitri Alperovitch, a founder of cyber security firm CrowdStrike, told the US newspaper that "Any time you see Iranian escalation, as with their buildup of rocket capacity in Syria, you have consistently seen Israeli retaliation with bombing runs on those positions. So it appears they have now applied that doctrine in cyberspace."
In a column by Israel Defense's Amir Rapaport on May 15, Arik Brabbing, former head of the Israel Security Agency's SigInt and Cyber Division, described how the incident could have widespread implications worldwide and could even be seen as the opening shot in a new type of war.
