Russia to blame?
Who has the most to gain from this? USA. Their politicians, are to blame because they follow the military establishment without question. The military establishment is to blame for creating these exploits and not informing companies of the security flaws in products. Lastly the end user or company are to blame for not having an offsite or disconnected backup. Backup, backup. I have spent years telling clients that they need backup systems and i still lots who arent willing to spend they money. Some just have to learn the hard way.
