Virus writers have created a spyware package that poses as an extension to the Firefox web browser.

FormSpy, which poses as the legitimate NumberedLinks 0.9 extension, is programmed to steal confidential information from compromised machines including passwords, credit card numbers, and ebanking login details. The malware is also capable of sniffing passwords from ICQ, FTP, and email traffic before sending this data to a hacker-controlled website.

FormSpy is normally downloaded onto compromised machines already infected with another Trojan program, called Downloader-AXM. It can also spread as a drive-by download from compromised websites.

Downloader-AXM began spreading via virus infected spam messages (example here) earlier this week. Fortunately, the attack is not yet widespread, according to net security firm McAfee, which has published a detailed write-up of the threat here. ®

i wondered when this would happen.

Presumably, this rogue extension didn't appear on the official Firefox site? If it did, that's very bad. Hopefully, by sticking to the official download locations for extensions, uses should be kept safe. :|

yeah, i doubt it did. The firefox mod people test all of the extensions...

I've just installed an extension from Firefox.

A box came up stating a new extension for firefox had just been released and to close my browser to install it, which I did.

Could this be the virus?

THIS link will give you more information Lona.

Thanks Clive.

I checked my extensions on firefox and there is nothing showing as numbered links 09.

I've ran my antivirus and no virus found.

Hope it was just a co-incidence. :?

Was it one you already had, which just needed updating, Lona?

I've just checked my updates and it says it was a security update (2006071912)

Phew! Glad to hear everything is OK Lona!
