Smuggling drones into Iran
The Mossad and the military worked together for at least three years to lay the operational groundwork, according to a former intelligence officer who said he had knowledge of the attack. This person spoke on condition of anonymity given the sensitivity of the subject.
The attack built off knowledge Israel gained during a wave of airstrikes last October, which “highlighted the weakness of Iranian air defenses,” said Naysan Rafati, an Iran analyst at the International Crisis Group.
To further diminish Iranian air defenses and missile systems at the start of last week's attack, Mossad agents had smuggled precision weapons into Iran that were prepositioned to strike from close range, according to two current security officials who spoke on condition of anonymity to discuss the missions. Those weapons included small, armed drones, which agents snuck into the country in vehicles, according to the former intelligence officer.
Using AI and human intelligence to select targets
To analyze information it gathered, Israel used the latest artificial-intelligence, or AI, technology, said an intelligence officer involved with selecting individuals and sites to target. He said AI was used to help Israelis quickly sift through troves of data they had obtained. That effort began last October according to the officer, who spoke on condition of anonymity because he was not authorized to talk to the media; it was one month before Netanyahu said he had ordered the attack plans.
An investigation by The Associated Press earlier this year uncovered that the Israeli military uses U.S.-made AI models in war to sift through intelligence and intercept communications to learn the movements of its enemies. It's been used in the wars with Hamas in Gaza and with Hezbollah in Lebanon.
The intelligence officer involved in identifying the possible targets said options were first put into various groups, such as leadership, military, civilian and infrastructure. Targets were chosen if they were determined to be a threat to Israel, such as being deeply associated with Iran's Revolutionary Guard — a paramilitary force that controls Iran’s ballistic missiles.
