There are tons of hacks for Eve, its just people keep them proprietary. There are a few I know about, and probably a lot more that I don't.
In other games where its Side A vs. Side B (WoW, SW, most team FPS modes, etc..) you'll see a lot of hacks and odds are both sides may even be using them. In Eve though, its really every man (or corporation) for themself. You do anything and everything to gain an advantage for yourself and cripple the other side. Releasing a hack publically could be detrimental to your own survival, and the death penalty in Eve can be quite severe and quite expensive, more than any other game I know - people have been known to come down with clinical depression for losing titans in that game.
The very nature of the server culture is very clandestine and nobody is going to post a hack unless they are quitting forever and want to do some kind of goodbye blowout. The vendor, CCP, is also known for cheating in their own MMO and it was a hacker who actually stole the data to prove it and the company itself has even acknowledged it had a "lack of oversight" of the matter in one of its devblogs.
I've done a memory dump of the game and a lot of the variables are actually encrypted in memory, so I know CCP tries to make things difficult. I do believe a guy in Pandemic Legion made a crack that decrypts it and reads variable data out.... there are some others who know too - of course, I can't *prove* it because *everybody* denies hacking or cheating in that game but I know it was possible during the appearance in local exploit of 2008 and caught in 2010. I've personally never gotten my hands on the code though, although I've played around at hooking things in the game, but my hooks kept failing every patch so I just threw the thing away......
