    The 2014 FIFA World Cup in Brazil is all but underway, and the fervor of such a prestigious and newsworthy event is already setting competing nations' populations on fire. Unfortunately, cybercriminals are getting into the mood too. Besides recently flooding the internet with phishing scams and the taking down two Brazilian government sites by hacktivists (the Sao Paulo Military Police website  and the official World Cup 2014 Brazil website), cybercriminals are also targeting the mobile scene with scads of World Cup-themed mobile malware  - ...
