Beijing scores number one spot for malware

In June, some 40 percent of malicious software worldwide originated from Beijing, nearly doubling from 21 percent in May, said Simon Heron, managing director for security vendor Network Box Corp.

Spam from Beijing, however, dropped from 11 percent to 5 percent over the same time period, he said.

Beijing kept the number one spot for malware, followed by Wattleup, Australia, at 3.7 percent, and Madrid, Spain, at 2.5 percent, according to Network Box. The percentage is calculated from event logs transmitted by about 700 customers using Network Box's security appliance, which has a firewall along with antispam, antivirus, antiphishing and content filtering technologies. The company catches about 4 million samples of malicious software a day.
