  • Microsoft disclosed on Saturday its plans to fix the bug, which targets Internet Explorer versions 9 through 11.
  • Those versions take up 26.25 percent of the browser market, according to FireEye, the cybersecurity software company that caught the bug.
  • The bug, however, reportedly affects versions 6 through 11.
  • Together, those versions dominate desktop browsing, accounting for 55 per cent of the PC browser market, according to tech research firm NetMarketShare.
  • In addition to possibly switching to an alternative web browser, US-CERT advised businesses to consider using a free Microsoft security tool known as EMET, or the Enhanced Mitigation Experience Toolkit, to thwart potential attacks.
  • Security experts say EMET is helpful in staving off attacks, but businesses are sometimes reluctant to use it because it can cause systems to crash due to incompatibility with some software programs.

The U.S. Department of Homeland Security and the UK Government had advised computer users to abandon Microsoft’s Internet Explorer browser until the company fixes a security flaw that hackers have used to launch attacks.

The bug is the first high-profile security flaw to emerge since Microsoft stopped providing security updates for Windows XP earlier this month.  That means PCs running the 13-year old operating system could remain unprotected against hackers seeking to exploit the newly uncovered flaw, even after Microsoft figures out how to defend against it.

Microsoft Corp is rushing to fix the bug in its widely used Internet Explorer web browser after a computer security firm disclosed the flaw over the weekend, saying hackers have already exploited it in attacks on some U.S. companies.

Microsoft disclosed on Saturday its plans to fix the bug, which targets Internet Explorer versions 9 through 11.
