Stretch - not sure.
That third-party hackers might help them in accomplishing their goals is also a stretch.
If the estimates from the US special forces raid which terminated their head of oil production and pinched all of his hard drives last year are correct, they have more than enough money to purchase the best attack kit money can buy from Russia, Ukraine or somewhere else in the ex-CIS.
What is more worrying is that they will continue having the money. Turkey put into a dispute state (which means that deliveries will stop) their Gasprom agreement last month (long before the shoot-down incident). That is 25% of their energy production. What people do not realize is that they are a major manufacturing site today. They build everything from Bosh (and under license) chainsaws to Transit vans and Renault Clios. The energy for that has to come from somewhere and the money they pay for the oil burned to attain it will be more than enough for the recipient to purchase an attack kit.
