"A device capable of intercepting phone signals was likely deployed during the 2024 Democratic National Convention (DNC) in Chicago, WIRED has learned, raising critical questions about who authorized its use and for what purpose.

The device, known as a cell-site simulator, was identified by the Electronic Frontier Foundation (EFF), a digital rights advocacy organization, after analyzing wireless signal data collected by WIRED during the August event.

Cell-site simulators mimic cell towers to intercept communications, indiscriminately collecting sensitive data such as call metadata, location information, and app traffic from all phones within their range. Their use has drawn widespread criticism from privacy advocates and activists, who argue that such technology can be exploited to covertly monitor protesters and suppress dissent.

The DNC convened amid widespread protests over Israel’s assault on Gaza. While credentialed influencers attended exclusive yacht parties and VIP events, thousands of demonstrators faced a heavy law enforcement presence, including officers from the US Capitol Police, the Secret Service, Homeland Security Investigations, local sheriff’s offices, and Chicago police."

Secret Phone Surveillance Tech Was Likely Deployed at 2024 DNC

Data WIRED collected during the 2024 Democratic National Convention strongly suggests the use of a cell-site simulator, a controversial spy device that intercepts sensitive data from every phone in its range.

"Some of the world’s most popular apps are likely being co-opted by rogue members of the advertising industry to harvest sensitive location data on a massive scale, with that data ending up with a location data company whose subsidiary has previously sold global location data to US law enforcement.

The thousands of apps, included in hacked files from location data company Gravy Analytics, include everything from games like Candy Crush and dating apps like Tinder to pregnancy tracking and religious prayer apps across both Android and iOS. Because much of the collection is occurring through the advertising ecosystem—not code developed by the app creators themselves—this data collection is likely happening without users’ or even app developers’ knowledge.

“For the first time publicly, we seem to have proof that one of the largest data brokers selling to both commercial and government clients appears to be acquiring their data from the online advertising ‘bid stream,’” rather than code embedded into the apps themselves, Zach Edwards, senior threat analyst at cybersecurity firm Silent Push and who has followed the location data industry closely, tells 404 Media after reviewing some of the data."
