Fun fact. Saudi Aramco got hit with malware that took down basically their entire computer system. The hackers then demanded $50m in ransom.

The virus was used for cyberwarfare[4] against national oil companies including Saudi Arabia’s Saudi Aramco and Qatar’s RasGas.[5][2][6] A group named “Cutting Sword of Justice” claimed responsibility for an attack on 30,000 Saudi Aramco workstations, causing the company to spend more than a week restoring their services.[7]
