A Russian national who is believed to be a key member of the international hacker group known as “Qilin” has been captured by Japanese police and extradited to Germany, according to investigative sources cited by JiJi. The group is associated with ransomware operations that encrypt data and disrupt victim systems, with Qilin claimed to have conducted attacks against organisations worldwide.
The German authorities had been seeking the individual in connection with a ransomware incident targeting a German company. The article notes that, in 2025, Qilin claimed responsibility for a major system outage affecting Asahi Group Holdings, the Japanese food and beverage company, although it does not specify the precise nature of the link to the current extradition. The report attributes the information to investigative sources and references coverage from The Japan Times.
The article does not provide further technical details about the exploit methods or the evidence tying the suspect to specific operations beyond these statements.
