Human Factors
We were climbing out of DEN on the EEONS 8. Crossed HIDEF at 10;000 feet and started the climb again. We started to pick up wake turbulence from the 777 in front of us through about 11;000 feet. We received a call from ATC for traffic northeast of us as we were coming through 11;500 feet. We started looking for the traffic and when I looked back inside we were going through 12;000 feet about 1-2 miles prior to SHOBO. We began correcting back to 12;000 feet. Max altitude was about 12;300 feet. No call or mention of the deviation from ATC.
While climbing out on flight from DEN via EEONS8 departure from 34L; we were given a traffic call from ATC as we neared SHOBO. At the same time; we encountered wake turbulence from a heavy aircraft on the same departure. As Pilot Monitoring; I was looking north for traffic as the aircraft was responding to the turbulence and controlling the aircraft. Simultaneously; we neared SHOBO; which has a no higher than 12;000 feet restriction. PIC called altitude at approx 250 feet above the restriction; and smoothly leveled; then began descent to maintain 12;000 feet until passing SHOBO; then resumed climb. No ATC comm was received during this time.
B737NG flight crew reported a distraction from wake turbulence contributed to climbing through an altitude restriction departing DEN in trail of a B777.
