by Internal documents leaked how Iran tracked and controlled protesters’ phones. Iran uses a cellular network computer system called SIAM to provide cell phone operators with a series of remote commands to alter, disrupt and monitor how customers use their phones. These tools can slow down network connections, crack call encryption, track the movement of individuals or large groups, and provide detailed metadata revealing who is talking to whom, when and where. SIAM’s internal documents came from cell phone operator Ariantel and were provided by a hacker who claimed to have hacked Ariantel, who believed it was in the public interest to make the documents public given the ongoing protests.
