(The Hosting News) – A new security flaw has been discovered in Microsoft’s Internet Explorer, leaving many computers vulnerable to attacks from potential hackers.
According to The Washington Post, users running versions 6 through 11 of Internet Explorer have been affected by the flaw, with Microsoft noting that it is aware of “limited, targeted attacks” aimed at exploiting the vulnerability.
FireEye, the cybersecurity firm that discovered the hole, said hackers had already exploited the flaw in a campaign called “Operation Clandestine Fox” designed to attack U.S. financial and defense companies.
The firm stated that the attacks had been aimed at versions 9 through 11 of the web browser.
“An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights,” said Microsoft in a security post.
The vulnerable versions of Internet Explorer account for 26.25% of current web browsers.
