Reuters reports on UK publicly attributing and blaming Russia for last years NotPetya attack, which crippled multiple UK government agencies and businesses:

The so-called NotPetya attack in June started in Ukraine where it crippled government and business computers before spreading around the world, halting operations at ports, factories and offices.

Britain’s foreign ministry said the attack originated from the Russian military.

“The decision to publicly attribute this incident underlines the fact that the UK and its allies will not tolerate malicious cyber activity,” the ministry said in a statement.

“The attack masqueraded as a criminal enterprise but its purpose was principally to disrupt,” it said.

“Primary targets were Ukrainian financial, energy and government sectors. Its indiscriminate design caused it to spread further, affecting other European and Russian business.”

UK is showing the current US administration how to play hardball politics against Russia. Since the US is not publicly condemning Russia for their bad behavior, our allies will have to fill in that gap until the administration changes its tune.
