A malicious batch of adware and spyware has appeared that can use Firefox and other alternative browsers to infect Microsofts IE.
According to a researcher at Vitalsecurity.org in the United Kingdom, if a user visits a site hosting the malicious code and agrees to install the applications despite security warnings, Internet Explorer will automatically run and deluge the computer with pop-up ads and offers, regardless of IE security settings.
While the security and infection threat is relatively low—in addition to the security warnings, the code only affects users of Suns JRE (Java Runtime Environment), and so far is only found at a Neil Diamond lyrics site—it illustrates the continued expansion of malicious code targeting alternative browsers, as well as a unique cross-browser capability.
"As virus writers get more sophisticated, they are looking at more products to exploit," said Gregg Mastoras, a senior security analyst at Sophos in the United Kingdom.
"Windows and Microsoft products are going to be the first targets because theyre so ubiquitous. Other applications will become targets as they become more popular."
Consumers love for IE is on the rocks, but with more than 25 million installs, Mozilla Organizations Firefox is one browser likely to see more attacks and exploit code heading its way.
"Firefox will retain an edge in security for some time, but the notion that youll be impervious to threats due to using Firefox is an illusion," said Jim Slaby, a senior analyst with the Yankee Group.
"The criminal element has decided that its profitable enough to write malware that targets it."
This code, however, doesnt work only through Firefox to get at IE.
