From ComputerWorld.com "Trend Micro site infected users with Trojan"
Antivirus vendor Trend Micro Inc. confirmed Thursday that "some portions" of its site had been hacked earlier this week, but hedged when asked if those pages had been serving up attack code to unsuspecting visitors.
"'When users viewed any of the modified pages, they were reconnected to other sites without realizing it, and a type of virus was installed on their computer that causes them to download other viruses in a series,'" Yomiuri Shimbun, one of Japan's largest newspapers.
Sophos, a Trend Micro rival, claimed that the hack had been an SQL injection attack and included a link to an alert Trend placed on its Japanese-language site that identified the malware as JS_DLOADER.TZE. The alert also said that users could have been infected by accessing one of 11 infected pages on the Japanese site or 20 pages on the English site, or by clicking a link embedded in the malware's name
