Italy is suffering from a barrage of remote attacks launched from hundreds of compromised websites, security experts have warned. Researchers at Symantec reported that attackers have injected 'iframe' tags within the HTML files on compromised sites. The tags redirect users to a site that runs MPack, a utility that attempts multiple exploits and malware installations. More than 65,000 users had been redirected to the malicious page since Friday afternoon, and more than 7,000 successful exploits had been carried out.
Symantec researcher Elia Florio warned in a company blog that users should update antivirus software and all system and third-party software that can be vulnerable to attacks. Florio warned that MPack attempts to exploit multiple vulnerabilities and applications, including flaws in QuickTime and WinZip
