Narrative:

Cleared by approach from a base leg for 8L to descend to 1500 feet and turn inbound to intercept final approach course. We were advised of traffic in front of us and to follow. We were not cautioned that it was a heavy and no caution of wake turbulence. At this point we were only told he was 4 miles in front of us. I saw him and the runway and we were cleared for the visual. I could see he was ahead and below us. As we turned and descended we slowed and got flaps in. [The captain] was just about to brief that he was going to stay high when we hit the wake turbulence. We were still on the autopilot and the aircraft was upset to a sharp right bank. Because of the loss of lift we descended even more and were now pointed about 45 degrees to the right. They were also landing on 9. [The captain] quickly disengaged the autopilot; added power; and climbed back towards the direction of our runway. As a result we got an RA to descend back down. We responded and I immediately alerted tower that we were responding to an RA as a result of the deviation caused by the wake turbulence. We were assigned a further climb and heading to re-sequence us for another arrival. There were many aircraft within the whole time frame that were commenting to approach and tower that they couldn't maintain the high speeds ATC was asking for. Another aircraft performed a go around. Completely unrelated to us. After the fact; we realized that ATC was keeping everyone fast and close and we realized that they did not give us the proper separation nor warning of the heavy in front of us. I feel ATC was completely at fault for this occurrence. We had a wake turbulence encounter that never should have happened. We performed the way we are supposed to for avoidance and we were put in a dangerous situation. In hindsight; if I had known the turn behind the heavy was assigned at an unsafe distance; I would have requested a longer downwind to increase separation. We assumed that ATC was doing their job.
