Symantec recently released a ranking of which countries are responsible for most of the world's cybercrime. Countries with high rates of high-speed Internet connections rank the highest on the list, as we'd expect, with the top 3 countries being the US, China and Germany.
Symantec put together this list by looking at malicious code, spam zombies, number of websites hosting phishing sites, number of bot-infected computers controlled by criminals, and country of attack initiation. The study investigated data for 2008 to come up with this list.
As you can see, the US accounts for some 23% of the world's malicious computer activity. That's a big jump from those countries ranked lower on the list, with the US leading the way on nearly all of the malicious activities tracked by Symantec.
If you download the latest Spam Intelligence report, which looks at spam in the second quarter of 2009, you'll see that overall levels of spam are on the rise. Malicious websites are also on the rise, with 67% more malicious websites blocked per day in June vs May of this year.
