Police agencies received a record number of queries related to cybercrimes in the January-June period, but arrested fewer online criminals. They also confirmed for the first time the existence of a new form of online banking threat known as the man-in-the-browser attack.

During the six-month period, police were consulted 54,103 times in relation to online crimes — up 37.3 percent from the same period last year and the most since records began in 2000, data compiled by the National Police Agency showed Thursday.

The agency added that the number of cybercrimes that actually led to arrests was down around 10 percent to 3,697 cases.
