Malware attacks decline from the US, but increase from China, Russia and Korea

Thirty-five percent of all Internet intrusion attacks are coming from Korea, according to Network Box. Analysis of all Internet threats in November by the company shows that Korea accounts for more than double the intrusions of its nearest competitor, the US (14 per cent).

Spam and viruses are on the decline from the US, following the shutdown of the McColo spam hosting service earlier this month. Although over the full month, the US was the biggest source of spam and viruses, this dropped sharply towards the end of November, when China took the top spot in the spam charts.
