Germany's domestic intelligence agency has warned against a cyber group belonging to Russian military intelligence (GRU) Unit 29155, saying it has carried out cyberattacks against NATO and EU countries. In a post on social media platform X on Monday, the Bundesverfassungsschutz said it was issuing the warning against the group known as UNC2589 alongside the FBI, U.S. cybersecurity agency CISA, the NSA and further international partners. The warning comes at a time of heightened anxiety in Europe over suspected Russian hackers and spies since Moscow's invasion of Ukraine in 2022.
