In an article on American cyber warriors’ disappointing showing in tackling Islamic State’s communications and recruitment online, The New York Times has this gem:

Even one of the rare successes against the Islamic State belongs at least in part to Israel, which was America’s partner in the attacks against Iran’s nuclear facilities. Top Israeli cyberoperators penetrated a small cell of extremist bombmakers in Syria months ago, the officials said. That was how the United States learned that the terrorist group was working to make explosives that fooled airport X-ray machines and other screening by looking exactly like batteries for laptop computers.

The intelligence was so exquisite that it enabled the United States to understand how the weapons could be detonated, according to two American officials familiar with the operation. The information helped prompt a ban in March on large electronic devices in carry-on luggage on flights from 10 airports in eight Muslim-majority countries to the United States and Britain.

It was also part of the classified intelligence that President Trump is accused of revealing when he met in the Oval Office last month with the Russian foreign minister, Sergey V. Lavrov, and the ambassador to the United States, Sergey I. Kislyak. His disclosure infuriated Israeli officials.

The report suggests US President Donald Trump did not compromise any Israeli spy embedded in the jihadist group, as previously reported and feared, but also indicates the US president did compromise a vital cyber-espionage capability that was saving lives.
