How VMware helps combat Viruses



I am not talking about a new Anti-virus solution or a new product, even though VMware does offer VMsafe for this exact purpose. image

Today I was hit with a very clever phishing attack.

Details can be found here. In short a customized email that was sent to large number of employees specifically addressed and personalized.The link was to a a site that looked like a Outlook Web Access page with a message telling that the IT support should click on the file to update your settings. Of course the file is a Trojan which does all kinds of nasty things as you can see on this report.

Now how is this connected to VMware? Well I knew this was a virus. But we needed to assess what it was doing, and the only to do that is to run the file. But knowingly infecting your computer with something like this is not the brightest idea to put it mildly, and who can predict what it will do?

But what if you had a machine that you could run the virus on, disconnected from the network, record the actions, export log files etc. and then return it back to the original state?

Do I hear anyone say a VM? Anyone?????

So this is how it went

  1. Workstation VM.
  2. Host-Only Network
  3. Snapshot VM
  4. Disconnect VM network card
  5. Import exe file (virus) with USB key
  6. Start up Wireshark
  7. Start up Procmon
  8. Run exe file
  9. Record all actions
  10. Stop Procmon and Wireshark capture
  11. Save captures for further analysis
  12. Export all to USB key.
  13. Revert VM snapshot to previous state.
  14. Repeat process twice more

Now if I wanted to I could have reverted the snapshot back the previous state before the virus had touched it, and continued to use it, But since this is a test VM that I use for these kind of incidents, I trashed it. Better be safe than sorry.

Logs were analyzed, virus activity was identified and measures were taken to protect the network. Report sent to AV Software provider to provide updated signature files that will identify and remove the virus.

You just gotta love the wonders of Virtualization, don't ya?

Hope you enjoyed the ride!

How to create an exe package in Windows



A colleague (thanks Natan) of mine reminded me of a simple but not very well know feature that exists in Windows.

We all download software from the Internet or install applications off a CD or some other media. This is also true if you need to install/transport information into a VM that is not connected to your network.

Some people package them as Zip files, some as ISO's and some as exe files. Did you ever wonder how these exe files are created??

Expensive Software packagers? Compression utilities? Well, most of us do not know that there is a utility built into the Windows operating system.

The utility is called IEXPRESS, and this is one of the easiest was to make a executable archive.

There is no shortcut available for the utility, but all you need to do is start the search box in Vista/Windows 7 or go to %systemroot%\system32\iexpress.exe

image

So here we go

image

Choose your desired option

image

Name your Package

image

Fill in your desired text

image

Add a License if you would like

image

Choose your files that you would like in the package

image

Choose some more options

image

image

Give the location for the package and some more options

image

And it does the work

image

And I now have a package

image

And of course in reverse - double click on the exe

image

image

image

And as they say, "A picture is worth more than a thousand words!!"

Oh yeah, did I mention that this is available in all Microsoft Operating systems??
