The Structure of Conficker

Bookmark and Share blog has update regarding Conficker worm. They have visualized Conficker.C and released a video for it.

This is what original blog post says about the video…

“The video is a 3D animation of the functions inside Conficker.C and their functional relationships. Yellow balls are functions found inside Conficker. Green loops are functions imported from Dlls and red boxes are jump holes into other functions.

OpenID and I got too many of them.

Bookmark and Share

Most of the service providers ( e.g. social service provider such as Google,Yahoo,Microsoft) support OpenID. And those who don’t, are either trying to support it or eventually support it due to its wide acceptance.

For those who want to know what is OpenID? check out video below…

The basic motive behind OpenID was to eliminate the need for multiple usernames across different websites, simplifying your online experience. As most of the users already have user ids with different service providers, we will eventually end up having too many of OpenID(s) pertaining to single user.

Currently most of the service providers either don’t have facility to disable OpenID mechanism or if it is there then it is not accessible that easily. The point is if some service converts their user ids to support OpenID then they should be providing mechanism to disable OpenID  on individual user id basis. Advantage being that user will eventually has option to retain kind of OpenID from service provider he desires.

What’s your opinion on this?

Virtualization Security? Virtual Machine Trojans are here.

Bookmark and Share

We all know the technologies that exists today to secure infrastructure from Trojans.  Current technologies that are available will protect infrastructure if some anti-malware or anti-virus is installed on your machine.

But what if someone downloads virtual machine (VM) image directly from Internet on your IT infrastructure?  There is no way that security software installed on your machine will able to recognize threat inside your VM image as your security software may not able to dig into your VM image or may not have access to your VM image (that you have booted). Hence Trojan inside your virtual machine will never get scanned or caught.

Virtual Machine Trojan (ViMtruder) comes embedded inside virtual machine image. You can read a article detailing threat of virtual machine Trojan at

ViMtruder has client/server architecture. Client is installed insider virtual machine and control server machine will be somewhere on Internet. Client runs automatically when VM image boots up and tries to contact periodically to control server on Internet using outbound port 80 (http port). It should be noted that http port 80 is generally open under most of the firewall policies. The possible threat is once ViMtruder client connects to control server it can scan network infrastructure where VM image is booted. There could be many other attacks that could be possible on network infrastructure.

You can download POC (Proof-Of-Concept) code from

So next time when you download any virtual machine image from Internet then make sure you download it from trusted source. Install and boot it first in isolated network environment (may be I am too paranoid) and make sure it is clean from such treats.

IMO, there could be serious implications of this considering wide spread of cloud computing and virtualization technologies that are being used with cloud computing.

World’s First Cloud OS: VMware vSphere 4

Bookmark and Share

Yet another new development into Cloud computing domain.

Today VMware has announced VMware vSphere 4, a Cloud OS platform. As I understood (correctly?), it is a next generation of VMware Infrastructure that is will be called as VMware vSphere. The key difference between Cloud OS and OS (Linux,Windows,AIX,Solaris) installed on machine is that Cloud OS manages data center while OS installed on machine manages only that machine.

VMware’s vSphere will manage data center as depicted in image below and will comprise of two main components,

1. Application Services
2. Infrastructure Services

You can find announcement about VMware vSphere 4 at VMware site. You can also watch video available at VMware vSphere page to get more visual understanding.

So it seems VMware has edge over other virtualization players. Do you agree?

Monitoring Web/Internet

Bookmark and Share

We often hear about monitoring web. Generally it is related to monitoring web traffic.

Have you ever wanted to monitor web for your interest? How about different updates that you want about specific domain e.g. technology, politics and different job openings etc? Most of us will take help of Google search to get to know about something(?). How about automating this task and get updates about your interests directly in your email account? We will take help of Google to keep us informed about latest happenings around the web. 

So let’s start. Suppose we want to monitor updates regarding cloud computing and utility computing (being currently hot topics across web). Google provides interesting service called Google Alerts. We will use this service to solve our purpose.

Just sign in and you will end up in “Manage your Alerts” page. Now press “New Alert” button.You will see a new row with a text box for your search terms. Enter "Cloud Computing" | "Utility Computing" term. Then select type from the lists based on your monitoring needs such as news,blog,web,comprehensive,video and groups. We will select comprehensive for wider coverage of our term or interest. Select “Email” delivery (Feeds are also possible) and frequency as “as-it-happens” and press “Create Alerts”.

Now you will receive frequent email alerts in your Gmail account for cloud computing and utility computing. We have just seen one of the use cases of using alerts. You can also create alerts for your name to see how your name is appearing on web if you want another use case.

There is also a paid service called GoogleAlert (they are not affiliated with Google). However, I haven’t used it personally.

Let me know how you utilize Google alerts to your benefit.

Consolidate your Online Identities and Social network contacts with

Bookmark and Share

In 24th Feb 2009 article, Online IDENTITY buzz resolved... , we had discussed about online identity. Most of us have different identities with different service providers such as yahoo, hotmail, Google etc.

This post is about a service called (Content Hub & Identity Management Platform). This is one more example of how cloud computing is helping different technologies. Just go to FAQ page at and select “how does work?” They are using Amazon EC2 and S3 system.


They help us manage and own our online identity on web. They provide free domain (So hurry, if you want to grab one for you) , OpenID and a website. You can consolidate all your identities at one place. e.g. you can add twitter,flickr,facebook etc…

I have just created my site called “”.


Currently I have updated my twitter and blog services on “” domain/site. I have also imported my Yahoo,Gmail contacts.  So this will give us a single platform to centrally manage most of our online identities.  I am really impressed by their concept. They also allow us to create multiple personas to help us manage our identity and relate it to different services and three personas (Friends, Public, Work) are available by default. See image below.


However, to my disappointment they currently do not support Orkut which,in my opinion, is one of the popular social networking sites in Indian subcontinent (You have right to disagree :) ). Hope to see orkut as a new crown in supported list of services as currently they are in beta state.

Just check it out and let me know your comments.

Content filtering software: Testing for Partial/MIME messages

Bookmark and Share

Welcome to this new post. Today we will see how to test your content filtering software (on your network gateway, hopefully) for partial/mime email messages.
In order to follow this post, you need basic understanding of networking, Linux/Unix and your content filtering software. This post is aimed at software test engineers however it can also benefit network administrators or system administrators as well.
Before continuing lets see what partial mime message means. It is rather a feature available in MIME which can be exploited to deliver unwanted contents. So basic idea is if you were to send a large file using email then you can break email message into multiple (partial) messages of equal size and deliver it to its destination. On other end, mail client will receive all parts of that single message and regenerate original one. MS outlook express will regenerate complete email message out of different partial email messages. However, this can be exploited or misused for unwanted purposes.
So open question is how do we protect these partial messages? and in my opinion it is best to prevent partial messages altogether. So this can be implemented on user end using mail client that do not support partial messages or blocking such messages on your gateway itself. Best way is to block partial messages at gateway level.
So next thing is how do we verify if content filtering gateway is blocking incoming partial mime messages. Answer is to test it.  How do we test it is what we will see below.
First enable partial/mime message filter and apply some action such as BLOCK, email alert or simple alert based on your content filtering software.
Next, you need to download and install tool called ‘mpack’  on your Linux/Unix box. A quick goggle search led me to mpack man page.
# mpack –s “Test Subject” –m 1024 –o partial_mime <File_Name>
The above CLI will generate files of 1024 size with file named partial_mime.01, partial_mime.02 etc…
Now we can use standard ‘mail’ CLI available on all unices to send all these generated files… You can also pipe output of mpack to mail CLI to automate this process. This (Automation) is the prime objective of using mpack tool (easy automation :) ).
Now verify if all files are blocked or alerts are received on your gateway software.
References: Refer to RFC2046, RFC2646,RFC3798, RFC5147 and RFC5321 @
