WASHINGTON, DC, Jun. 26 (UPI) -- Hundreds of Web sites worldwide have been infected with the "Download.Ject" or "Scob" virus, created by Russian hackers.
The Washington Times reported Saturday the infected sites caused visitors to install a "trojan" program that allows someone to control a computer remotely.
The hackers took advantage of vulnerabilities in servers using Microsoft's Internet Information Services program to infect the Web sites. Computers with the Microsoft Internet Explorer Web browser were infected if they were part of a Microsoft operating system.
"An unsuspecting Web surfer might fall victim," said Neil Mehta, a research engineer with Internet Security Systems in Atlanta.
Web security firms and the U.S. Computer Emergency Readiness Team issued a warning Friday and said while this latest virus has not circulated as quickly as other recent viruses and worms, it might grow more pervasive over time.
Microsoft recommended Internet Explorer users set their security settings to the highest level.
