Scareware now targets Firefox browser

We have been reading about a lot of rogue software targeting Mac users – but its now time for Firefox users to be very careful.

A new scareware detects your user-string from your browser and if you are using Firefox, it will display a fake alert stating that a security scan is in process, with a button recommending that you Start Protection.If you click on the Start Protection. button, it will proceed to install a rogue antivirus software on your Windows computer.

Firefox does NOT include a virus scanner, so should you see such an alert, you know what to do! Simply close the browser and make it a point to not visit the website where you may have seen this alert, reports Sophos.

If you use Internet Explorer, you may get the regular Computer folder dialog box which appears to be running a system scan inside your IE.

I guess we are going to be seeing more and more of such ways to steal money from people. Cybercriminals will use such scareware tactics to scare people into downloading malicious software onto their computers and/or pay for a fake rogue software. This is something we all need to take care of.

Mozilla confirms infected Firefox add-ons slipped through

Mozilla late Thursday confirmed that it had failed to detect malware in a pair of Firefox add-ons, which may have infected up to 4,600 users. The add-ons have been removed from Firefox’s official add-on download site.

According to an entry on the Mozilla Add-ons blog, Sothink Web Video Downloader 4.0 and all versions of Master Filer were infected with Trojan horses designed to hijack Windows PCs. Both add-ons were in the “experimental” area of Firefox’s add-on download site, where newer extensions remain until they undergo a public review process.

To install experimental add-ons, Firefox users must view and accept an additional warning. Master Filer was downloaded about 600 times in the five months ending Jan. 25, when it was pulled from the site. Sothink Web Video Downloader 4.0 was downloaded approximately 4,000 times between February and May 2008.

The most up-to-date version of the latter, which captures streaming videos in a variety of formats, is 5.7. Any Windows users who installed one of the two add-ons would have also silently executed the Trojan, which would then infect the PC. Mac or Linux Firefox users who installed the add-ons were not affected.

Rivals challenge Microsoft browser settlement


Three rivals of Microsoft’s Internet Explorer web browser are seeking last minute changes to a proposal, that would see new users of Windows presented with a ballot screen of the top five browsers. Rivals believe that the current ballot screen proposal still gives Internet Explorer an unfair advantage.

After a complaint from the makers of the Opera web browser, the European Commission decided in January that Microsoft’s inclusion of Internet Explorer in Windows constituted an abuse of their dominant market position. In October, the Redmond-based company proposed a so-called browser “ballot screen”, which would display a list of the top five browsers to consumers when they boot a new computer for the first time.

The commission has asked Microsoft’s rivals, who still appear to be unhappy with the proposal, to comment on the company’s offer by Monday.

Oslo-based Opera believes that the ballot should be displayed on a screen that does not contain the Microsoft logo. “It would be like having an election ballot where the name or logo of one candidate is displayed separately, prominently up in the corner of the ballot,” said Mr. Lie, chief technology officer at Opera. “You wouldn’t want that.”

Opera also want Microsoft to prevent Windows from displaying the standard security warnings that occur when users download software from theInternet.

Mozilla, the creators of Firefox, are concerned about the ballot screen’s design. Displayed within an Internet Explorer window, the screen will list the five most popular browsers in alphabetical order from left to right, giving first spot to Apple’s Safari. Jenny Boriss, a Mozilla designer, criticized the display in a post on October 16th, writing, “Windows users presented with the current design will tend to make only two choices: Internet Explorer because they are familiar with it, or Safari because it is the first item.” She went on to suggest that the browsers be displayed randomly.

Mr. Lie has said Google, Mozilla and Opera will send separate letters to the commission, detailing their requests for changes.

European competition commissioner, Neelie Kroes, has said she will take Microsoft to court should they fail to agree to a fair settlement. However, Mrs. Kroes, who is likely to step down at the end of the year, has said she would prefer to settle open cases before leaving.

According to research firm Net Applications, Internet Explorer current has a 67 percent share of the browser market, following by Firefox with 24 percent. Apple’s Safari has 4.4 percent, Google’s Chrome 3.5 percent and Opera just 2 percent.
