The life cycle of web-based malware or malicious software has become so quick that infected websites often disappear before anyone can shut them down when detected.
Just in the past three months, security researchers at AVG Technologies have seen the number of new infected web sites grow by 66%, from 100,000 to 200,000 per day to 200,000 to 300,000 per day. And the company's researchers expect the trend to continue.
Google has noticed a similar, if less pronounced, trend in spam. The company reported Monday that spam volume rose 25% in 2008 compared with the amount recorded in 2007. And because there are more infectious sites, cyber criminals can afford to have them active for less time.
Due to mass SQL injection attacks and other techniques, even well-regarded legitimate web sites may be compromised to host to malicious software. Cyber criminals continue to refine social engineering attacks that dupe users into taking harmful action.
