ESSPEE : eth0 issue in Installation

1.   First thing first ...what's ESSPEE.So friends who are aware of whats Backtrack R3....ESSPEE is a derivative of BackTrack 5, based on Ubuntu 12.04. Designed for users who wish to use only free software. It is packed with featured security tools with stable configurations....and now for those of you who wish to know the expanded form of ESSPEE ...its EXTREME SECURITY SCANNING PENETRATION TESTING & EXPLOITATION ENVIRONMENT.....:-)

2.   So after downloading this from  here...and after installing I came across a small issue of eth0 NIC not being detected unlike regularly where it gets detected automatically vide a DHCP config.So the answer is a small tweak that is required while selecting the Mac address of the eth0 as shown in the screen shot below :

3.    That's it....and now ur internet will be on with network adapter configured to NAT....

1.    Adobe, who gave us the the ever comfortable PDF..thats the "Portable Document Format" in the early 1990's never thought like how this can become a security threat by the simple action of opening it only....yess!!!this post will give a small insight of how things really work behind the scene in execution of a malicious PDF....

2.  So first of a PDF becomes a malicious document?The answer to this question is simple embedding of a JAVA SCRIPT, that is not seen but only executed once a PDF is antivirus will be able to identify of what malicious thing lies behind a normal PDF that u and me use if u scan a malicious PDF with your Antivirus,it is veri unlikely to be do we know then whether a PDF is malicious or not?...thats what this post shows here....I came across a tool known as PDFid in the BACKTRACK R3 that I was running in Virtual Box.

3.   Few lines about the tool....this was developed by Didier Stevens who blogs at this helps us to differentiate between PDF Documents that could be malicious and those that are unlikely to be....The tool is based on the fact that that a  typical PDF File comprises of header, objects, cross-reference table (to locate objects), and trailer.So , if there is a tool that can find out if any one of them is available in this PDF...things can become like for example...if a PDF that has no purpose of embedding or holding a JS inside it,then a eye brow raise is certain as to why should it be PDFid tool comes to rescue us out of this question...First the typical structure of a PDF with its one line explanation is given below :

“/OpenAction” and “/AA” (Additional Action) specifies the script or action to run automatically.

 “/Names”, “/AcroForm”, “/Action” can also specify and launch scripts or actions.

“/JavaScript” specifies JavaScript to run.

 “/GoTo*” changes the view to a specified destination within the PDF or in another PDF file.

 “/Launch” launches a program or opens a document.

“/URI” accesses a resource by its URL.

“/SubmitForm” and “/GoToR” can send data to URL.

“/RichMedia” can be used to embed Flash in PDF.

“/ObjStm” can hide objects inside an Object Stream.

4. So now I have set up a VB machine running BTR3 that would run this tool and find out if the PDF that I have analyzed is malicious or not? These are the screen shots showing a step by step scene of how u do it....

1.    Strange is the heading and so is the story....according to the news doing the rounds in cyber space.Anti-virus software pioneer John McAfee says he is moving every four hours to avoid Belizean police who wants to question him about the murder of his neighbor, a fellow true or untrue is this ...m no one to comment....but being an ardent McAfee user for long on my various VMs....I would like to wish him the best.....more on the story that I read from is available here.....

Otome 3D : World’s first 3D-Printing Photo Booth

1.    At one of my earlier posts about 3D Printers about 4 months back,I had discussed about the phenomenal world of 3D Printers....the vast applications envisaged and what is left to imagination of how do we use this technology....but then I could not find any commercially available products available to comman men.....but here we are....a company Harajaku in Japan will house the world’s first 3D-printing photo Booth by Otome 3D. This can ensure that you have your very own Madam Tussad-esque replica, up to 20cm, of yourself. The process involves scanning of entire bodies of subjects for about 15 minutes, after which, you are reproduced in material, to much awe and astonishment. More details about this at here

FEDORA 17 & VIRTUAL BOX : Virtualbox Installs but won't load

1.   This particular problem kept me busy the whole day....and in fact I reached a point of frustration that I should switch back to Ubuntu that I was earlier the problem goes like when I install virtual box via the rps and yum commands ...I used to invariably get some odd message that mostly included the following :

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/etc/init.d/vboxdrv setup'

2.    I would not actually lie about it...but i checked about so many forums that gave relatively the same solutions that you would have mostly found out by now...but to no the two command simple solution that would make you VB run like a horse without any issues goes like this :

yum install dkms binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel

/etc/init.d/vboxdrv setup

offcourse you have to run this as a su -

3.   Do let me know if u r stuck on this again...the sets of commands that I run since morning as root are produced below for info only.BUt I am sure the commands above would solve your problem.
