Maybe because everybody know, but nobody is talking..?
There are those that don't talk and those that flat out deny it (and then call you a noob/idiot). You have to realize that no one that hacks will admit it. They knew that when they started doing it they would be questioned and therefore were all ready prepared to lie to your face. The only way they'll admit it is if they think you all ready know.
Like the BF3 hacker, most people probably start doing it because they think others are. So unfortunately, if you're an above average player and you happen to woop up on someone repeatedly, you might just spawn a hacker. I've seen this happen a few times.
I'm thinking WREX could find most things. I definitely know it looks everywhere (even on usb drives). I thought I saw Wormbo's name in the list of identified hackers. Funny that he's mentioned as someone that helped design a 2k4 anticheat in that article.
It's bad that these are out there & the companies should be paying the hackers to find ways to prevent the hacks. Sounds like they're onto a winner though anyway as he talked about it being a subscription model - so recurring revenue.
Fortunately, I don't think that UT3 has many hackers. Only on the very odd occasion do I wonder about it in warfare. Its usually when someone kills you first time, every time for 5 or 6 kills in a row and you look around and can't see where they shot you from. I had that recently from someone in a goliath on serenity, but after that game I got a lot more frags on him than he did on me so it was probably just a case of sneaking out, great shot, sneak back in for a few times.
It's also rarely to get accused of aimbotting too nowadays, which is a reflection of the communities feeling of how prevalent they are (or how crap I am! ).
It was posted 5.09.12 on the Anandtech forums. This might be old news to some, but for me it's new news. I posted this to make people aware of this and to maybe spark someone to fight against this hack. Regardless though, I thought this interesting to read.
