Symantec Internet Security Threat Report 2016

Symantec discovered more than 430 million new unique pieces of malware in
2015, up 36 percent from the year before. Perhaps what is most remarkable
is that these numbers no longer surprise us. As real life and online become
indistinguishable from each other, cybercrime has become a part of our daily
lives. Attacks against businesses and nations hit the headlines with such
regularity that we’ve become numb to the sheer volume and acceleration of
cyber threats.
