EFF mourns the loss of Mark Klein, a hero who risked everything to expose a massive spying program by the NSA that violated millions of Americans’ rights. Mark, a former AT&T technician, revealed the existence of a secret room where data was copied and sent to the NSA. He shared documents and evidence with major media outlets and politicians, sparking lawsuits and calls for accountability. Despite facing personal risks and legal threats, Mark’s bravery inspired many to demand an end to illegal mass surveillance. While reforms have been made, the fight continues as Section 702, which authorizes surveillance, is set to expire in 2026. Mark’s legacy lives on in EFF’s ongoing efforts to protect privacy rights.
