Mass hack plants malware on thousands of webpages2010-06-10 11:05 by DanielaTags: malware
More than 100,000 webpages, some belonging to newspapers, police departments, and other large organizations, have been hit by an attack over the past few days that redirected visitors to a website that attempted to install malware on their machines. The mass compromise appears to have affected sites running a banner-ads module on top of Microsoft's Internet Information Services using ASP.net, said David Dede, head of malware research at Sucuri, a website monitoring firm. Intljobs.org, The Wall Street Journal's wsj.com, and tomtom.com.tw have all been hacked, in addition to The Jerusalem Post and the police department website for the UK county of Strathclyde, as El Reg has reported previously here and here. Google searches on Tuesday indicated more than 100,000 pages were infected, Dede said, but that number had shrunk to about 7,750 at time of writing. The sites were infected using SQL injection exploits, which allow attackers to tamper with a server's database by typing commands into search boxes and other user-input fields. The hackers used the exploit to plant iframes in the compromised sites that redirected visitors to robint.us. Malicious javascript on that site attempted to infect end users with malware dubbed Mal/Behav-290 according to anti-virus firm Sophos. Read more -here-
