IRAN’S SECRET MANUAL FOR TRACKING AND CONTROLLING PROTESTERS’ MOBILE PHONES Intercept -Oct 27th 2022 Sam Biddle, Murtaza Hussain AS FURIOUS ANTI-GOVERNMENT protests swept Iran, the authorities retaliated with both brute force and digital repression. Iranian mobile and internet users reported rolling network blackouts, mobile app restrictions, and other disruptions. Many expressed fears that the government can track their activities through their indispensable and ubiquitous smartphones. Iran’s tight grip on the country’s connection to the global internet has proven an effective tool for suppressing unrest. The lack of clarity about what technological powers are held by the Iranian government — one of the most opaque and isolated in the world — has engendered its own form of quiet terror for prospective dissidents. Protesters have often been left wondering how the government was able to track down their locations or gain access to their private communications — tactics that are frighteningly pervasive but whose mechanisms are virtually unknown. While disconnecting broad swaths of the population from the web remains a favored blunt instrument of Iranian state censorship, the government has far more precise, sophisticated tools available as well. Part of Iran’s data clampdown may be explained through the use of a system called “SIAM,” a web program for remotely manipulating cellular connections made available to the Iranian Communications Regulatory Authority. The existence of SIAM and details of how the system works, reported here for the first time, are laid out in a series of internal documents from an Iranian cellular carrier that were obtained by The Intercept. According to these internal documents, SIAM is a computer system that works behind the scenes of Iranian cellular networks, providing its operators a broad menu of remote commands to alter, disrupt, and monitor how customers use their phones. The tools can slow their data connections to a crawl, break the encryption of phone calls, track the movements of individuals or large groups, and produce detailed metadata summaries of who spoke to whom, when, and where. Such a system could help the government invisibly quash the ongoing protests — or those of tomorrow — an expert who reviewed the SIAM documents told The Intercept.
