Microsoft announced on Friday that it's in the process of developing a patch for a zero-day vulnerability in Internet Explorer that has been exploited in targeted attacks, reportedly by a threat group tracked as DarkHotel.
According to Microsoft, the vulnerability can be exploited for remote code execution in the context of the targeted user.
Microsoft says it has learned about the vulnerability from Google's Threat Analysis Group and Chinese cybersecurity firm Qihoo 360, which have apparently seen the weakness being exploited in limited, targeted attacks.
Qihoo 360 has found evidence suggesting that the vulnerability has been exploited by the DarkHotel threat group, which some believe may be sponsored by South Korea.
Security professionals have advised users to simply stop using Internet Explorer, but as an advisory published last week by Siemens shows, some web-based software can still only run in Internet Explorer.
