Around 33 percent of the world’s cyber attack traffic traced back to China, a new report said.
Between July and September of last year, about 33 percent of the attacks originated in China, double the percentage in the previous quarter, according to the report by Akamai Technologies, an Internet services firm.
The U.S. was the second-largest source with 13 percent. Next in line are Russia, Taiwan and Turkey, which each accounted for less than 5 percent of the attacks, according to the Akamai report.
China has been the top source of cyber attacks since the end of 2011, the Akamai report said. Most of the attacks originating in China targeted a particular database system made by Microsoft, said David Belson, who edited the report.
Receiving 30 percent of observed attack traffic, Port 445 (Microsoft-DS) remained the most targeted port, according to the report. Port 23 (Telnet) was a distant second at 7.6 percent.
“It may have been a flareup in some sort of exploit that is trying to spread,” Belson said.
The Akami report also contains the most recent list of countries and regions with the fastest Internet access.
