When we learned about the Sony DRM software that was being employed very ala-spyware, it was mused at that point that it could be used for dangerous and unsavory things. It's already occurring, as cheaters playing in Blizzard's World of Warcraft online game have found ways to use it to their advantage. Blizzard, under just as much controversy as Sony for their software, uses an aggressive scanning method to detect cheat programs when people are playing. The Sony backdoor prevents that scan tool from detecting anything specially named, allowing the cheaters to avoid being detected. What has the industry come to? Industry spyware fighting industry spyware. Sony's initial reaction to this fiasco has been to provide a patch that disables the cloaking ability of their software.
