New Patch introduced faster detection methods?

After the new patch, all the new hacks released are being detected very quickly. Did nexon maybe add in a new security measure? Or are the hacks too similar to the old ones that causes faster detection? Like for instance rapid fire pretty much crashes no matter what hack you use because its easily detected, so would it be certain aspects of the hack or a new detection method?

Might be nexon getting smarter, like you said new detection system. But thats just my opinion if anyone else got an idea please comment!
