The Times said the work by Israeli cyber operators was a rare success of Western intelligence against the constantly evolving, encryption-protected and social media-driven cyber operations of the extremist group.
It said the Israeli hackers penetrated the small Syria-based cell of bombmakers months ago, an effort that led to the March 21 ban on carry-on laptops and other electronics larger than cellphones on direct flights to the United States from 10 airports in Turkey, the Middle East and North Africa.
The Israeli cyber penetration was the source of US information about how the group was developing explosives that couldn't be detected by standard screening because they looked identical to laptop batteries, according to the Times.
The intelligence was so good that it also included the detonation method for the bombs, the Times said, citing two US officials familiar with the operation.
Following the US laptop ban, Britain announced a similar prohibition for flights originating from six countries.
Israel's contribution to the intelligence on the laptop bombs became public after President Donald Trump revealed details of the plot to Russian Foreign Minister Sergei Lavrov in a May 10 White House meeting.
Trump's disclosure "infuriated" Israeli officials, according to the Times.
