I would hope that a country with the largest military industrial complex in the world can hack a group of camel herders in a desert. Doesn't seem particularly impressive
Also since they supplied equipment to them it would not have been as difficult to trojan it.
And I will infinitely fault the Obama administration for providing technology which immediately fell into jihadist hands, which any reasonable analyst would have told them would happen.
But it's not accurate to say the US 'supplied' equipment to ISIS. ISIS stole it.
