Wow, US government did something useful for once.
They recovered a lot of the Bitcoin that was stolen through the hack. Can't imagine how they did this though. The article mentions who was behind the hack, they said the people who are responsible will probably not face charges because they're outside of US. Seemed very weird how the oil company willingly gave up millions on a whim, guess it was peanuts compared to the amount of money they were losing shut down.
The recovery is nothing compared to the economic damage the shutdown caused. It may deter future ransomware attacks in the future though.
The pipeline was effectively out of business until the ransomware was removed from their systems. This meant they either had to rebuild all their systems or pay the ransom. It seems they had difficulty even after paying.
