An anonymous reader writes "A report by V.i. Labs revealed the top methods used for cracking software and the top piracy groups responsible. The findings revealed that the piracy groups and the reverse engineering talent they recruit can tamper with a variety of hardware and software based licensing systems to enable overt piracy. The top five piracy groups (out of 212) contributed 59 percent of the cracked releases in the research sample. The top five most active groups in this sample were Lz0 (Linear Zero), NULL, Shooters, LND (Legends Never Die) and Magnitude."
