PunkBuster - Wikipedia, the free encyclopedia ROFL @ no5 in the reference list!
'On March 23, 2008, attackers published and implemented a proof of concept exploit of PunkBuster's indiscriminate memory scanning. Because PunkBuster scans all of a machine's physical memory, malicious users were able to cause mass false positives by transmitting cheat program signatures as text on a high population IRC channel. When PunkBuster detected the signatures within users' IRC client text buffers, the users were banned.[5] On March 25, 2008, Even Balance confirmed the existence of this exploit, and advised users not to run any other programs at the same time as PunkBuster protected games.[6]
Other false positives have been documented. A well known gamer under the handle eDiT'Lio was banned by PunkBuster during an ETTV International match between Belgium and Sweden.'
