Daniel Lippmann reports in Politico:
The U.S. government concluded within the past two years that Israel was most likely behind the placement of cellphone surveillance devices that were found near the White House and other sensitive locations around Washington, according to three former senior U.S. officials with knowledge of the matter.
But unlike most other occasions when flagrant incidents of foreign spying have been discovered on American soil, the Trump administration did not rebuke the Israeli government, and there were no consequences for Israel’s behavior, one of the former officials said.
The miniature surveillance devices, colloquially known as “StingRays,” mimic regular cell towers to fool cellphones into giving them their locations and identity information. Formally called international mobile subscriber identity-catchers or IMSI-catchers, they also can capture the contents of calls and data use.
The devices were likely intended to spy on President Donald Trump, one of the former officials said, as well as his top aides and closest associates — though it’s not clear whether the Israeli efforts were successful.
Trump is reputed to be lax in observing White House security protocols. POLITICO reported in May 2018 that the president often used an insufficiently secured cellphone to communicate with friends and confidants. The New York Times subsequently reported in October 2018 that “Chinese spies are often listening” to Trump’s cellphone calls, prompting the president to slam the story as “so incorrect I do not have time here to correct it.” (A former official said Trump has had his cellphone hardened against intrusion.)
