Summary
A Turkish hacker group, Redhack, leaked cellular phone numbers of over 4,000 personnel from a major telecommunications company, along with numbers belonging to government ministers, deputies, the prime minister's son, and a pro-government journalist. The breach occurred after the company changed phone numbers previously disclosed by the hackers during parliamentary debates on controversial internet legislation, which opponents argued would enable excessive surveillance and keyword-based censorship.

The incident amplified public backlash against the proposed law, reigniting protests over perceived violations of digital privacy and freedom.

Description
In January 2014, during Turkish parliamentary debates over a contentious internet regulation bill, the hacker collective Redhack publicly disclosed cellular phone numbers belonging to government ministers and members of parliament. The group accused Turkcell, Turkey’s largest mobile operator, of providing privileged assistance to these officials by changing their phone numbers after the initial disclosure paralyzed their devices. Redhack claimed this selective intervention contrasted with standard customer service protocols, alleging preferential treatment for political figures. In response, Turkcell denied any impropriety, asserting that number changes were a routine service available to all subscribers upon request through its call centers. The company emphasized its commitment to uniform service standards for all clients.
Following Turkcell’s statement, Redhack escalated its actions by leaking the cellular numbers of over 4,000 Turkcell employees, broadening the scope of exposed data beyond government officials. The group also published the number of Prime Minister Recep Tayyip Erdoğan’s son, Bilal Erdoğan, and Rasim Ozan Kütahyalı, a columnist for the pro-government Sabah newspaper, framing these disclosures as a protest against the draft internet law. The bill, introduced amid a high-profile corruption scandal, proposed expanded government authority to monitor online activities and restrict keywords without judicial oversight. Public opposition surged, with critics condemning the legislation as a violation of privacy despite government claims it aligned Turkey with "developed country standards." The incident amplified existing activism against internet restrictions, reigniting protests under slogans like "don’t touch my Internet," which had previously drawn thousands of demonstrators. Turkcell maintained its position that no exceptional measures were taken for officials, while the data leaks intensified scrutiny of corporate-government relations and digital rights in Turkey.
