Remote code execution in Microsoft Internet Explorer

Not patched

Vulnerability exploitation was detected by 360 Core Security. The company uncovered a zero-day vulnerability in IE, dubbed ‘double play’, that was triggered by weaponized MS Office documents. The experts have been observing an APT group targeting a limited number of users exploiting the zero-day flaw.

Hackers can use the ‘double play’ flaw to implant a backdoor Trojan and take full control over the vulnerable machine.

The APT group was delivering an Office document with a malicious web page embedded, once the user opens the document, the exploit code and malicious payloads are downloaded and executed from a remote server. The later phase of this attack leverages a public UAC bypass technique and uses file steganography and memory reflection loading to avoid traffic monitoring and achieve loading with no files. This ‘double play’ vulnerability may affect the latest versions of Internet Explorer and applications that are with IE kernel.

For now most of the victims are located in Asia.
