'Greasemonkey' Malware Targets Firefox

snydeq writes "Researchers have discovered a new type of malware that collects passwords for banking sites but targets only Firefox. The malware, dubbed 'Trojan.PWS.ChromeInject.A,' sits in Firefox's add-ons folder, registering itself as 'Greasemonkey,' the well-known collection of scripts that add functionality to Web pages rendered by Firefox. The malware uses JavaScript to identify more than 100 financial and money transfer Web sites, including PayPal, collecting logins and passwords, which it forwards to a server in Russia. Trojan infection can occur via drive-by download or download duping."

    Well, this just proves that it's easier to develop for Firefox than IE. ^_^ Of course, it's a very backhanded compliment.

    does it affect all platforms since it's Java?

    It's not Java, it's JavaScript - two very different languages linked only by a common marketing fuckwit.

    Since I haven't yet RTFA, I can't comment with any authority (as if I ever do), but if it's a javascript exploit, then I suppose it could affect any platform. My credit union's online banking portal only allows me to use Internet Explorer, so I can't even get to my bank account through Firefox or Opera or SWIron (which I prefer to Chrome). Oh the irony! Here's one instance where IE is a safer alternative to FF!

    It's javascript in firefox, so the malware writers could have made it platform-independent with a little bit more work. But did they? NO! Yet another example of ignoring the Linux platform.
