File Introduction

At the beginning of the year, large-scale protests erupted in Iran and quickly evolved into a movement with broad political demands. As part of its forceful suppression measures, the Iranian government implemented an almost nationwide internet shutdown, aiming to cut off information channels both domestically and internationally. Against this backdrop, the Starlink satellite internet system, capable of bypassing ground infrastructure, became a critical variable in the flow of information. Iranian citizens used Starlink terminals smuggled into the country to transmit images and details from protest sites abroad, with related information spreading globally via international social media platforms. This was viewed by Iranian authorities as a direct threat to domestic stability, fundamentally driven by concerns that the outflow of uncensored information could trigger unfavorable international public opinion and potentially provide a pretext for external intervention. Consequently, the interference with and blockade of Starlink became an extension and core component of Iran’s overall "digital firewall" strategy, with the primary goal of completely blocking this government-uncontrolled information channel and maintaining its information control system.

The Iranian government's blocking strategy is a comprehensive technical operation that combines "nationwide internet routing disruption" with "targeted interference with Starlink satellite signals." At the technical level, the blockade goes beyond simple network access control and escalates into active electronic countermeasures. The authorities have deployed military-grade and satellite signal jammers to disrupt the synchronization between terminals and satellites; implemented ground-based multi-point signal shielding in key areas to create interference barriers; and injected noise into specific communication frequency bands to reduce the signal-to-noise ratio. According to technical assessments, the data packet loss rate in some areas is estimated to be as high as % to %, rendering services nearly paralyzed. This blocking operation is carried out through a coordinated system of state agencies with clearly defined responsibilities: the Iranian National Center for Cyberspace is responsible for overall planning, the Ministry of Communications and Information Technology handles the physical disconnection of traditional internet infrastructure, and the Electronic Warfare Department of the Islamic Revolutionary Guard Corps serves as the core technical force executing the Starlink signal interference mission. Additionally, security forces are tasked with seizing Starlink users and confiscating equipment, while specialized reconnaissance teams are responsible for locating signal sources and assisting in house searches. The entire operation follows a clear, progressive path: first, completely sever conventional networks; then use technical means to locate and interfere with satellite communication signals; and finally, eliminate residual connections through offline physical searches and legal deterrence. The Iranian government has classified privately held Starlink terminals as "illegal communication devices" and imposed severe penalties, while establishing a "whitelist" mechanism to ensure that its own and controlled media's limited network access remains unaffected.

In response to the communication disruptions caused by government blockades, targeted measures have been taken, including providing free Starlink satellite internet services to Iranian users to counteract the communication interruptions resulting from government restrictions. On the technical front, efforts have been made to combat electronic interference implemented by the Iranian government through software upgrades, such as enhancing the system's anti-jamming capabilities by dynamically adjusting connection protocols. It is noteworthy that Starlink's actions are not purely commercial or technical but have also involved coordination with political forces. High-level officials of the U.S. government engaged in political coordination, planning discussions on how to leverage Starlink as a tool to alleviate Iran's blockades, thereby integrating the commercial satellite network into a diplomatic framework.

This report further explores the unconventional means and organizational networks through which Iranian citizens access Starlink services under strict blockade, analyzing the pathways through which Starlink equipment enters regulated countries via smuggling and other channels. The report also examines the potential militarization of Starlink technology in conflict zones and related cases, while assessing the international community's response to the Iranian blockade incident and the complex role played by Starlink. Through an in-depth analysis of this high-tech confrontation case, the report reveals the long-term, complex, and high-tech nature of the struggle for information control and counter-control in the digital age.
