“The attack involves a threat actor emailing a Microsoft Word document to a targeted user with an embedded OLE2link object. When the user opens the document, winword.exe issues an HTTP request to a remote server to retrieve a malicious .hta file, which appears as a fake [Rich Text Format] file. The Microsoft [HTML Application] loads and executes the malicious script.” added by FireEye in a blog post.

The bug is related to Object Linking nad Embedding (OLE) feature of Microsoft. McAfee further added that the first attack was detected which took place in January.

There are some measures which will be taken by Microsoft for this bug problem. They will release their next Patch Tuesday security update as soon as possible to fix the situation. They are also planning to introduce Windows 10 Creators Update but users will be able to download the update before its official release.

For the time being precautions and warning have been given by McAfee. The users are said to not open the file from any “untrusted” sources. The problem will soon be fixed.

It is also said that the attack can not bypass the Protected View in Office Application. Therefore users are advised to enable this feature so that the bug can not exploit any further.
