If we look at wikileaks cables, then we can see that Pakistani intelligence agencies have been passing on terrorism related information to Mossad as well. In the 1980s, Israeli trainers were also present in training the "Muajahideen" forces against the Soviet and teaching them how to make bombs and other subversive tactics. Infact, a lot of soviet light weaponry that was destined to the PLO was captured by the Israelis was routed to Pakistan to pass it on to Afghanistan.
So although politically they oppose Israel and particularly use it in internal politics to discredit opposition leaders (calling them Israeli / Indian agents), realistic foreign policy needs have made them at times willing to work with Israel at the ISI/army level when needed.
Just like with other GCC countries, Israel-Pakistan relations are usually under wraps to avoid public outcry. Here is a good report on Israel-Pakistan relations over the decades. A must read for those interested
