I think yes, that is what the prosecutor from Germany said:
"According to Paul Pfeiffer, prosecutor in the city of Rostock in northern Germany, the operation was connected to a blackmail attack that hit several municipal institutions in the state of Mecklenburg-Western Pomerania in October 2021. As a result of the attack, the institutions were not able to carry out their tasks.
– During the investigations, which are still ongoing, an IP address was found that led to the VPN service Mullvad. The investigation is not directed towards the VPN service, the prosecutor writes in an email.”
