Trailrunner7 (1100399) writes "The number of compromised sites detected each month by Google's antimalware and anti-phishing systems has been dropping rather steadily from a peak of more than 300,000 in early 2009 and is now down around 150,000. However, the company's statistics also show that the number of outright malicious attack sites is back on the rise.
The company found that while it is still detecting about 9,500 malicious sites every day, the number of legitimate sites that have been compromised to serve malware has been dropping for the last few years. Those compromised sites typically are used in drive-by download attacks to install malware on victims' machines or use them as part of a botnet or to send spam. Some of those attacks also involve the use of other tactics such as social engineering or a series of redirects to push users to the compromised sites."
