A recently released report that analyzed the development of malicious code indicates that in 2013 as many as 30 million new strains of malware were introduced, an average of about 82,000 new variants each day last year, and accounted for one-fifth of the 145 million malware samples ever created.

“These numbers –which come as no surprise if we look at the trend set during the last 12 months– are certainly mind-blowing. Consider this: 20 percent of all malware that has ever existed was created in 2013,” the report states. “In a year that saw all kinds of cyber attacks, new waves of the infamous police Virus and the resurgence of ransomware specimens such as Cryptolocker, trojans continued to be the most common type of malware.”

Findings on the types of malware created in 2013 included:

  • Trojans – 71.11%
  • Worms – 13.30%
  • Viruses – 8.49%
  • Adware and Spyware – 6.93%
  • Other – 0.17%

Infecton rates correspond to the development breakdown accordingly:

  • Trojans infections – 78.97%
  • Worms infections – 6.89%
  • Viruses infections – 5.83%
  • Adware and Spyware infections – 5.03%
  • Other infections – 3.27%

China (54.03%), Turkey (42.15%) and Ecuador (40.35%) led the most infected nations in the report, followed by Peru (39.85%), Argentina (38.18%), and Russia (38.01%). The least infected nations included Belgium (25.40%), Denmark (25.34%), Japan (24.84%) and Netherlands (23.64%). The United States came in at 28.96%.

In addition to the malware analysis, the report also take a look at attacks, vulnerabilities, and trends in cybercrime and hacktivism, noting that there has been and will continue to be a sharp rise in operations targeting Android-based devices.

“Over the next 12 months we will have to pay special attention to Android threats, as they are clearly on the rise all around the world. In this context we can expect to see new waves of attacks aimed at stealing data and money. ”
