During the 2024 Democratic National Convention in Chicago, WIRED uncovered potential unauthorized use of a cell-site simulator capable of intercepting phone signals. The deployment of this device, detected by EFF through signal data analysis, raised concerns about the covert surveillance of protesters and the suppression of dissent. Despite the legal requirement for warrants to use such technology, there's uncertainty about its authorization, suggesting potential breaches of privacy law and illicit surveillance practices, without clear knowledge of who operated the device or their intention.
