According to the recently-released 2013 edition of the FireEye Advanced Threat Report, enterprises are hit by cyber attacks on average once every 1.5 seconds.

That's a notable surge from 2012, which saw attacks coming once every three seconds.

Malware has also become more pervasive globally -- FireEye found malware attack servers and command and control (CnC) infrastructure in 206 countries and territories in 2013, up from 184 in 2012. The U.S., Germany, South Korea, China, the Netherlands, the U.K. and Russia were home to the most CnC servers.


The top 10 countries that were most frequently targeted by advanced persistent threats (APTs) in 2013 were the U.S., South Korea, Canada, Japan, the U.K., Germany, Switzerland, Taiwan, Saudi Arabia and Israel.

In the first half of 2013, Java was the most common zero-day focus for attackers, while FireEye saw a surge in Internet Explorer zero-days used in watering hole attacks in the second half of the year.

"The increasing frequency at which cyber attacks are happening illustrates the allure of malware to those with malicious intentions,” FireEye senior global threat analyst Dr. Kenneth Geers said in a statement. "Across the board, we are seeing a global expansion of APTs, malware, CnC infrastructure, and the use of publically available tools to facilitate the attack process. The global scale of the threat has put cyber defenders in the very difficult position of not having any clue where the next attack will come from."
