Microsoft is under pressure to fix a security flaw found in the Internet Explorer browser which led to targeted attacks.
The vulnerability was found in Internet Explorer versions 6 through 11 and mainly affects users of the Windows XP.
Microsoft stopped updating the security on XP browsers just last month which resulted in targeted attacks and has left many users vulnerable.
In order to be targeted, users must be persuade to click on a link that opens a malicious website.
“An attacker who successfully exploited this vulnerability could gain the same user rights as the current user,” Microsoft said in the advisory statement.
Currently, 58 percent of people who use PC’s rely on Internet Explorer which means that many businesses and personal users could be at risk.
While Microsoft scrambles to repair the flaw, users of Internet Explorer are being cautioned to use other browsers until Microsoft releases an update.
The news comes just days after the Heartbleed bug, which targeted encryption software, was announced.
Microsoft issued a statement saying, “ we will take the appropriate action to protect our customers, which may include providing a solution through our monthly security update release process, or an out-of-cycle security update, depending on customer needs.”
