PARIS (AFP) -- Hundreds of Swedish supermarkets remained shut Tuesday after a major cyberattack that has crippled hundreds of companies worldwide for the past four days, with the perpetrators demanding $70 million in bitcoin to undo the damage.
Kaseya, the Miami-based IT company at the centre of the hack, said late Monday that up to 1,500 businesses had been affected by Friday’s attack, which has been blamed on Russian-speaking hackers.
