Britain has formally blamed Russia for the NotPetya ransomware attack in June last year, with Foreign Office Minister Lord Ahmad saying the decision "underlines the fact that the UK and its allies will not tolerate malicious cyber activity".
The container shipping company A.P. Moller–Maersk Group expects that a Windows ransomware attack it suffered in June will cost it between US$200 million and US$300 million.
The people behind the last malware attack, which began in Europe and then spread to other regions, appear to be trying to play down the theory that the attack was masterminded by a nation state.
