#4 Russia

Russia, a country in northern Eurasia (combined continental landmass of Europe and Asia), has accounted for 4.3 percent of the world's attack traffic during the fourth quarter of 2012, putting the country in 4th place. Russia's share decreased from 4.7 percent in the previous quarter and 6.8 percent in the year-ago period.

At least 40 companies including Apple, Facebook and Twitter were targeted in malware attacks linked to a cyber criminal group based in Russia or Eastern Europe, according to a recent Bloomberg News report.

According to Forbes, few nationalities are as good at making money from hacking than the Russians. Their share of the global cyber crime market, an estimated $12.5 billion black market, doubled to $4.5 billion in 2011, claims a study from Moscow-based Group-IB.

In November, 2012, a hacker group named ‘GhostShell’ has allegedly swiped 2.5 million Russian government accounts and records. The hack was retaliation against Russia’s long history as “a state of tyranny and regret,” Team GhostShell claimed in a PasteBin document.
