According to the results of the 2013 Global Corporate IT Security Risks Survey [PDF file], conducted by B2B International and Kaspersky Lab, 90 percent of those surveyed underestimated the number of new malware samples that appear worldwide each day (h/t Computer Weekly).

While 200,000 new malware samples appear daily, according to Kaspersky, 90 percent of survey participants named a lower figure, while 4 percent guessed too high and only 6 percent gave an accurate estimate.

The responses varied regionally, however -- in the Middle East, 24 percent of companies gave accurate estimates, while 4 percent in Russia did so, and the percentage of correct responses in other regions ranged from 5 percent to 7 percent.

Still, 66 percent of respondents had experienced at least one attack involving malware in the previous year.

The companies most frequently targeted in such attacks were in South America (72 percent), Russia (71 percent), North America (70 percent), Asia-Pacific (68 percent), and Western Europe (63 percent).

"Although the majority of companies are as yet unable to assess the actual scope of cyberthreats, on the whole businesses realize the importance of effective protection," the report states. "Malware, together with a broad range of attack scenarios involving company employees and their personal mobile devices, have become the main source of incidents in which compnaies lost valuable business data."
