In January 2023, the SPD Party Executive Board in Germany was targeted by a hacker attack that likely originated from Russia, exploiting an unknown Microsoft security vulnerability. A limited number of email accounts were affected, and a data leak cannot be ruled out. The attack was detected following warnings from security authorities and was jointly investigated with German federal security agencies. SPD General Secretary Kevin Kühnert confirmed the Russian origin and emphasized that the SPD would not be intimidated by such cyber attacks, reaffirming their stance against Russia's illegal war on Ukraine.
