"Illusion Gap" Malware Attack Bypasses Windows Defender Scans on Shared Folders Server

A new malware dubbed "Illusion Gap" exploits a design choice in how Windows Defender scans files stored on an Shared Folders (SMB) Server before execution.

In many offices, this is your local area network (LAN) drive, a dated term. The modern term is called Network-attached storage (NAS).

For Illusion Gap to work, the attacker must convince a user to execute a file hosted on a malicious SMB server under his control. This is not as complex as it sounds, as a simple shortcut file is all that's needed.

How Illusion Gap works

The problems occur after the user double-clicks this malicious file. By default, Windows will request from the SMB server a copy of the file for the task of creating the process that executes the file, while Windows Defender will request a copy of the file in order to scan it.

SMB servers can distinguish between these two requests, and this is a problem because an attacker can configure their malicious SMB server to respond with two different files.

The attacker can send a malicious file to the Windows PE Loader, and a benign file to Windows Defender. After Windows Defender scans the clean file and gives the go-ahead, Windows PE Loader will execute the malicious file without Windows Defender realizing they're two different things.

What is the average size of office and pdf documents?

Microsoft Enterprise Search conducted a survey in 2012 asking compiling statistics from 100 different data sources spread across tens of millions of searchable items, to answer this question. What is the average size of a typical office document.  I could not find a more recent analysis. 

Here are the results:

• The average size of an office document is 321 kB.
• Most web content is smaller than 200kB
• PowerPoint and PDF consume the most space
• Word documents are most frequent

Src: Microsoft Enterprise Search / SharePoint content, 100 different data sources spread across tens of millions of searchable items

Here's some SAN disk sizing if you have some data to back-up. For example you know that:

•  306 GB for  1 million documents 
• 2.98 TB for 10 million documents
• 5.96 TB for 20 million docs
• 8.94 TB for 30 M docs
• 14.9 TB for 50 M docs.

I have made request to both Bing and Google for an update. Can anyone can help?
