I see hacking takes 12 hours I have 1k Intell if I get a higher IQ does it become easier or only doing the job over and over and has anyone had luck with it Iv done it 3 times and only 1 success 

At low skill levels; it is difficult to do. having a higher intelligence, (1200) helps a lot. But don't be surprised to find you lose a lot, and get 1 every now and again, espeically if skill is less than 5%
