The US and UK governments haveattributed a massive ransomware attack from 2017 to the Russian military.
The NotPetya ransomware targeted companies inUkraine, attacking its government, financial and energy institutions last June.
The cyberattackended up costing Maersk up to $300 million in lost revenue.
The White House statement comes just a day after the UK government attributed the attack on the Russian military.
TheUkrainegovernment said it found evidencelinking the attack to Russian hackersin July.
“The malware was not designed to be decrypted.
This meant that there was no means for victims to recover data once it had been encrypted.
This is only the second time the agency has attributed an attack to a nation-state.
The first was when theNCSC attributed the WannaCry ransomware attack to North Korea.
From there, it spread to multi-billion-dollar organizations, which had branches in Ukraine.
Like the WannaCry ransomware attack, it used stolen techniques from the National Security Agency to spread rapidly.
The attack reached more than 200,000 computers around the world, even though it was only targeted toward Ukraine.
