Blackmailers demand ransom after hacker attack on Berlin state authorities
Approximately two weeks after a hacker attack on Berlin's state authorities, Governing Mayor Kai Wegner announced that the state is being extorted. The ransom demand arrived early Thursday evening, but Wegner emphasized that Berlin will not pay. The Senate convened a special session on Friday afternoon to address the situation. The cyberattack, which began around August 14, forced the isolation of two Senate departments from the state network for about a week, disrupting housing benefit applications and payments. While State Secretary for Digitalization Florian Hauer initially stated no sensitive data had been leaked, the Senate Chancellery later said this could not be ruled out. Wegner did not disclose the ransom amount or specific threats. Berlin's Interior Senator Iris Spranger confirmed that the upcoming state parliament elections on September 20 remain secure.
