A Russian-Canadian national has been arrested over LockBit cyber-attacks targeting critical infrastructure, US officials say.
Mikhail Vasiliev, 33, was arrested in Ontario, Canada, on 9 November, the Department of Justice (DoJ) said.
It said LockBit had been used against more than 1,000 victims who had faced ransom demands amounting to millions.
In August, a Holiday Inn hotel in Turkey was breached by LockBit, which released data stolen from the company.
There has been increased scrutiny on appropriate defences against cyber-attacks, particularly on Western financial institutions, in the wake of heightened tensions following Russia’s invasion of Ukraine early this year.
