McDonald's Guerrilla Fail

Today I bring you the ghost of a guerrilla campaign past-- a ghost that is probably still haunting McDonald's in Japan because it was such a complete, total, epic fail. Back in 2006, McDonald's and Coca Cola teamed up to give away 10,000 promotional mp3 players in Japan. Sounds like a good idea right? You would be wrong, because a bunch of the mp3 players were tainted with QQPass trojan malware. When users plugged their mp3 players into their computers, the virus would steal logins and passwords and communicate them back to the virus creator. While McDonald's instituted a recall and distributed a software patch, the PR damage was done. They should just stick to handing out unique toys in their Happy Meals.
