Researchers have discovered that a page on the My Opera community Web site is hosting malware related to an IRC botnet. The discovery comes just a couple of weeks after malicious code also was found on Google Code servers. My Opera is a community-based site that enables users to create blogs and share photos. Attackers have had a field day in the last couple of years compromising legitimate Web sites and placing malicious scripts on the pages. The tactic has paid big dividends for the crimeware gangs, as it gives them the opportunity to compromise large numbers of unsuspecting users who visit these sites.
