Microsoft Corp is fixing a bug in its Internet Explorer web browser after hackers were found to have exploited the flaw in attacks on some US companies, Reuters reported Sunday.
In an advisory to its customers posted on its security website, Microsoft said the bug is present in Internet Explorer versions 6 to 11, which account for 55 percent of the PC browser market, the report said.
However, PCs running Windows XP, which account for 15 to 25 percent of the PCs worldwide, will not receive any updates fixing the bug because the company stopped supporting the 13-year-old operating system earlier this month, according to the news agency.
Hackers have been exploiting the bug in a campaign dubbed “Operation Clandestine Fox”, cybersecurity software maker FireEye Inc. was quoted as saying.
