Sell your old PC & IT Hardware @ NCR Delhi

1.   Isn't it very often that you have a old working CRT monitor or a old pentium PC though working fine or even in a non workable condition and you find it hard to sell it to the local kabadi wala who would offer not greater the plastic scrap rate...and so that old box keeps lying in store room and you don't know what to do with it....do you know that even a dead motherboard would fetch you around Rs 150....but all this will be possible only if you hit it right...i mean you know a place to sell all this IT scrap....so i thought of writing this post..I have been to this shop at Nehru Place for about 4-5 years now....has a professional team and approach to rate your scrap be it working or not working!!!!

2.   Though I have no affiliation with this shop in any way but thought of sharing this exploitable info for all guys based in NCR.....few pics to help in identification for those of you who wish to visit this below :

ENCRYPTED E-MAILS @ DARK MAIL ALLIANCE

1.   How often we keep reading so much about privacy and IT security issues across the web and daily surf's!!!....but we only have more to believe that privacy with times to come will be a matter of past...be it your mobile with loads of applications inbuilt already or your exchange on yahoo or gmail etc..every one is trying to vie for your data in some form or the other...your sms..your mms...your contacts..your stored data on the SD card,your browsing history or your location at various times of the day etc etc.....every one wants all this to make your profile and then in the long run use all this to market or even blackmail you(who knows!!!!!)...future will buzz a lot with our past....

2.  In such times it is good to read about "Dark Mail Alliance". Extract from their website is produced below for general direction of purpose :

" To bring the world our unique end-to-end encrypted protocol and architecture that is the 'next-generation' of private and secure email. As founding partners of The , both Silent Circle and Lavabit will work to bring other members into the alliance, assist them in implementing the new protocol and jointly work to proliferate the worlds first end-to-end encrypted 'Email 3.0' throughout the world's email providers. Our goal is to open source the protocol and architecture and help others implement this new technology to address privacy concerns against surveillance and back door threats of any kind."

3.   Silent Circle’s team as mentioned in the extract is a unique and eclectic mix of world-renowned cryptographers, Silicon Valley software engineers, German VoIP engineers, Latvian system analysts and former US Navy SEALs & British Special Air Service (SAS) security experts....while Lavabit was an encrypted email service, founded in 2004, that suspended operations on August 8, 2013 after it was ordered to turn over its Secure Sockets Layer (SSL) private key to the US government.So the combo of these two majors can be a force to reckon with provided the policies and strategies do not bar them again in some manner...till then lets give a "good night" to privacy!!!

Dual Boot Mobile Phone : Ubuntu and Android

1.   Any time we speak about dual boot,it is a understood fact that we are speaking about a desktop or a laptop device...but what if there is a third answer to this....a MOBILE Phone!!!!!surprise surprise surprise..:-)...read on for what’s  in store ahead...

2.    Well...the first time I read about this concept...that says like you have the typical android OS for being used as a smart phone but in addition you can boot the same device with UBUNTU to get the desktop experience as u insert it in the dock....I was excited to know more and few facts after googling have emerged out as bought out below.

3.  The first Ubuntu smartphone has been announced by Canonical . Under the project code named Ubuntu Edge,the phone has almost everything that we don’t normally see.But first, Canonical wants to raise $32 million (21.5 million pounds) on Indiegogo to build this. The company is asking prospective consumers to put in money for it to make an Ubuntu phone and it is hoping to do it in 31 days.  At the time of writing this, it had already raised over $12,814,196.Details at http://www.indiegogo.com/projects/ubuntu-edge



4.  The phone is likely to go on sale in May 2014 and the brief specs out are as follows :

    Dual boot Ubuntu mobile OS and Android
    Fully integrated Ubuntu desktop PC when docked
    Fastest multi-core CPU, 4GB RAM, 128GB storage
    4.5in 1,280 x 720 HD sapphire crystal display
    8MP low-light rear camera, 2MP front camera
    Dual-LTE, dual-band 802.11n Wi-Fi, Bluetooth 4, NFC
    GPS, accelerometer, gyro, proximity sensor, compass, barometer
    Stereo speakers with HD audio, dual-mic recording, Active Noise Cancellation
    MHL connector, 3.5mm jack
    Silicon-anode Li-Ion battery
    Form Factor : 64 x 9 x 124mm

3.   Not just Android with Ubuntu,infact Microsoft has approached HTC with a plan to load Windows Phone 8 onto its Android handsets as a way to give consumers more than one platform option on their devices. In exchange for loading Windows Phone onto Android handsets, Microsoft would consider waiving licensing fees for using the mobile operating system, Amazingly, HTC is apparently warm to the idea and is pondering the logistics of making a dual-boot Windows-Android handset.

4.  So it is a welcome concept overall.But then from a security point of view the user will have to handle two attack surfaces in form of the two boot options.More details at the following links :

BACKTRACK 5 R3 : ReverseRaider

1.   This post will brief on a tool known as Reverse Raider available in the information gathering menu drop down in Backtrack 5

About the Tool 

2.   ReverseRaider is a domain scanner that uses various techniques, such as wordlist scanning to find target's subdomains or reverse resolution for a range of ip.It's fully multi-threaded and supports permutation on wordlist, IPv6 and various DNS options (e.g. no-recursion).

3. Developed by  Acri Emanuele at crossbower@gmail.com

Usage: reverseraider -d domain | -r range [options]
 

Options:

  -r    range of ipv4 or ipv6 addresses, for reverse scanning
        examples: 208.67.1.1-254 or 2001:0DB8::1428:57ab-6344
  -f    file containing lists of ip addresses, for reverse scanning
  -d    domain, for wordlist scanning (example google.com)
  -w    wordlist file (see wordlists directory...)
 

Extra options:
  

  -t    requests timeout in seconds
  -P    enable numeric permutation on wordlist (default off)
  -D    nameserver to use (default: resolv.conf)
  -T    use TCP queries instead of UDP queries
  -R    don't set the recursion bit on queries

4.   Most of the  DNS enumeration scripts available in backtrack focus on typical DNS but reverseraider does what it sounds like it might do which is enumerate reverse DNS names. Enumerating reverse DNS on an IP or set of IP’s can sometimes reveal information you did not previously have. It is possible to be targeting a web server that has a bunch of virtual hosts and you prefer to track down primary web site on the web server which is where reverseraider may provide the results necessary as it is more likely that the most important site on the virtual web server has reverse DNS configured on the host itself. 

5.   I found out this very useful and exhaustive post at http://www.question-defense.com/2012/04/01/backtrack-5-information-gathering-network-analysis-dns-analysis-reverseraider

This post gives an excellent description with details of three methods of using reverseraider.

BACKTRACK 5 R3 : LBD [ Load Balancing Detector ]

1.   Before we start working on this tool,we need to first get clear of what exactly is Load Balancing?

2.    Load balancing is a method to distribute workload over multiple computers , network links, central processing units, disk drives, or other resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload. So before any one performs a penetration test, some recon work needs to be done on the target domain to make sure it does not have the ability to misdirect any probes and attacks.

About the Tool : LBD

3.   LBD (Load Balancing Detector) is a small script that tells if a given domain uses DNS and/or HTTP Load-Balancing (via Server: and Date: header and diffs between server answers). The main purpose of the tool is to check if the given domain uses load balancing.In other words when a server uses load balancing to distribute its work load over multiple systems, it should not get clogged up with excessive requests that prevents disruptions. This will mostly be applicable to renowned websites to reduce their system workload and to prevent malicious DOS attacks.

Usage : ./lbd [Domain]

4.    I could not find any switch option that can be used with the command ....so the usage is simple....I have tried this on two sites : certifiedhacker.com and dvwa.co.uk.Screen shots of the results obtained are seen below :

BACKTRACK 5 R3 : FIERCE

1.  What's in a name ? But here when the name of the tool is FIERCE...it has the potential to grab eyeballs....about FIERCE first....Fierce is a perl script written by RSnake and helps at the first steps of a pentesting ie the reconnaissance. The focus of any pentester  is to gather as much info as possible about the target before starting the attack.Exactly like earlier tools discussed in the Information Gathering drop down of Backtrack 5 R3,FIERCE is used for DNS Enumeration and is a great tool for discovering non-contiguous IP address for a certain company. It is difficult to discover and gather information about a company network which is non-contiguous using traditional tools. Though we can use a normal scanner against an IP range, but if the IP ranges are nowhere near one another there may be chance of missing chunks of networks. For this type of situation FIERCE is used.The following is the working process of FIERCE.

First it asks DNS for the DNS servers of the target. If DNS server of target is misconfigured then fierce attempts to dump the SOA records for the domain. If it fails then it attempts to "guess" names that are common amongst different companies using bruteforce.

2.   The info gained from this tool FIERCE can be used by subsequent tools to be used like nmap, unicornscan, nessus, nikto, etc, since all of those require that you already know what IP space you are looking for.  This does not perform exploitation and does not scan the whole internet indiscriminately.  It is meant specifically to locate likely targets both inside and outside a corporate network.  Because it uses DNS primarily you will often find mis-configured networks that leak internal address space. That's especially useful in targeted malware.

SYNTAX :  perl fierce.pl [-dns example.com] [OPTIONS]  

3.  The switches that can be used with this command are shown in the screen shot below :

4.    So I tried running the tool on certifiedhacker.com & dvwa.co.uk and the output is shown below vide a screen shot :

This info will be good enough to march ahead from a pen tester point of view!!!!!!

BACKTRACK 5 R3 : dnswalk

1.   In this post I am going to show how the dnswalk works.Before you use this tool...there is a small twist to the tale...almost all users who use this command will invariably get the message " You will have to enable the component called 'universe'"....and for this..so to resolve refer my immediate earlier post here.First lets see what are the features of this tool...what actually it does and what is the syntax ?

Main Features :

 

2.    Dnswalk is a DNS debugger. It performs zone transfers of specified domains, and checks the database in numerous ways for internal consistency, as well as accuracy. Dnswalk should NOT be used without a firm knowledge of the DNS RFC's. The warnings and errors must be interpreted within the context they are being used. Something may be flagged as a warning, but in reality it is a really bad error. Conversely dnswalk will flag things as warnings and possibly even errors, but they may actually be perfectly "legal" or normal in your specific situation. Dnswalk is not an AI engine. It just provides useful information which you need to interpret.

3.   Another important thing about the tool is w.r.t the syntax.The domain name specified on the command line MUST end with a '.' ie a dot.If u simply type in man dnswalk at the terminal,you will most of the info than I have bought here...The syntax and the switch functions are briefly bought out here :

SYNTAX : dnswalk [ -adilrfFm ] domain.

-r = Recursively descend sub-domains of the specified domain. Use with care.
-a = Turn on warning of duplicate A records. (see below)
-d = Print debugging and ‘status’ information to stderr. (Use only if redirecting stdout) See DIAGNOSTICS section.
-m = Perform checks only if the zone has been modified since the previous run.
-F = perform “forced” checking. When checking an A record, compare the PTR name for each IP address with the forward name and report mismatches.
-i = Suppress check for invalid characters in a domain name. (see below)
-l = Perform “lame delegation” checking. For every NS record, check to see that the listed host is indeed returning authoritative answers for this domain.

Below I have bought out few screen shots on how the command may be used and what it brings out.I have used two domains for practise here.One is certifiedhacker.com and iitk.ac.in.The former does not bring out much but the latter brings out more info that I find amazing......so the first command tries to find zone transfer records of the target domain.

Command : dnswalk -r iitk.ac.in.

(Click on the Image to Enlarge)

(Click on the Image to Enlarge)

This command with other switches can be used in the same manner as shown above with the following switch combinations :

dnswalk -i iitk.ac.in.

Turns on warning of duplicate A records

dnswalk -a iitk.ac.in.

Performs debugging on the site

dnswalk -d iitk.ac.in.

Checks whether the domains are been modified are not

dnswalk -m iitk.ac.in.

If you wish to perform all the above things through single command line argument you can type the following.The same is shown in the screen shot subsequently

dnswalk -riadmfl iitk.ac.in.

(Click on the Image to Enlarge)

....and for a website that shows no result like certifiedhacker.com.....the screen shows the answer

[SOLVED] : You will have to enable the component called 'universe' backtrack

1.  In my attempts to try few tools like dnswalk and fierce...I used to see these messages that read like :

you will have to enable the component called 'universe'

Click on the image to Enlarge

So after many attempted failures that I am not going to share here...I am bringing out steps on how to resolve and start using the tools....

Click on the image to Enlarge

So the first command is to install synaptic that you can simply do by typing the following command as shown in the screen shot above :

apt-get install synaptic

Click on the image to Enlarge

After synaptic is installed you need to install gdebi by typing in the following command as shown in the screen shot above :

apt-get install gdebi

Click on the image to Enlarge

Click on the image to Enlarge

 Now after installing these two tools synaptic and gdebi,you have to follow the screen shots..Go to Systems > Administration > Synaptic Package Manager

Click on the image to Enlarge

 As the Synaptic Package Manager window opens up...go to Settings > Repositories

Click on the image to Enlarge

Then you see this...all the check boxes will be disabled as default as seen in the screen shots below :

Click on the image to Enlarge

 Just check all of them and click close

Click on the image to Enlarge

 Then click on Reload and you will see the downloading Package Information window as seen below :

Click on the image to Enlarge

 Then you simply reboot and try installing dnswalk...no issues...and you see going ahead with success...

BACKTRACK 5 R3 : dnstracer

1.  Dnstracer is another in the line of information gathering tool in Backtrack 5 R3 that determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the servers which know the data. It basically works by sending the specified name-server a non-recursive request for the name. If the name server does returns an authoritative answer for the name, the next server is queried. If it returns an non-authoritative answer for the name, the name servers in the authority records will be queried. The program stops if all name-servers are queried.

(Click on the image to enlarge)

The switches available with the command line are :

(Click on the image to enlarge)

As can be made out from the screen shhot above,the option switches have variety to offer and thus a whole lot of basic info on the specific DNS can be churned out.The syntax of the command is :

dnstracer [options] [host]

-c:    disable local caching, default enabled
-C:   enable negative caching, default disabled
-o:    enable overview of received answers, default disabled
-q     : query-type to use for the DNS requests, default A
-r     : amount of retries for DNS requests, default 3
-s      : use this server for the initial request
-t      : Limit time to wait per try
-v     : verbose
-S      : use this source address.
-4     : don't query IPv6 servers

In the screen shots below I have taken example of the dvwa.co.uk for running the command on.....the command run is

dnstracer certifiedhacker.com

dnstracer -q soa -o certifiedhacker.com

(Click on the image to enlarge)

Running the command with and without switches effects the final output of info as seen in the info....

BACKTRACK 5 R3 : dnsrecon

1.   Dnsrecon is another nice easy to use tool for pen testers for enumeration. The kinds of things dnsrecon can do are as follows:

    - Reverse Lookup against IP range
    - Perform general DNS query for NS,SOA and MX records
    - Cache snooping against Name Servers
    - Google Scanning for Sub Domains and Host

 2.   The command line usage and the few imp switch execution details are briefed here down :

   -h       --help                 Show this help message and exit
   -d       --domain            Domain to Target for enumeration.
   -c       --cidr                  CIDR for reverse look-up brute force (range/bitmask).
   -r       --range               IP Range for reverse look-up brute force
   -n      --name_server    Domain server to use, if none is given the SOA of the
                                      target will be used
   -D     --dictionary         Dictionary file of sub-domain and hostnames to use for
                                       brute force.
    -t     --type                  Specify the type of enumeration to perform:

Available through :
                           
Backtrack -> Information Gathering -> Network Analysis -> DNS Analysis -> dnsrecon

In this blog post,I  will be covering 3 enumeration techniques. These being:

    SRV records Enumeration
    Top Level Enumeration
    Standard Enumeration

(Click on image to Enlarge)

(Click on image to Enlarge)

 

 

To perform an SRV records enumeration against a domain the following input command will be run:

Code:

./dnsrecon.py -t srv -d

As an example if we wanted to do this to certifiedhacker.com, our command would be as follows:

Code:
./dnsrecon.py -t srv -d google.com

(Click on image to Enlarge)

Top Level Enumeration

For performing a top level enumeration the following command will be used :

Code:
./dnsrecon.py -t tld -d

If the same command is run for google.com,the following command will be used

Code:
./dnsrecon.py -t tld -d google.com
 

(Click on image to Enlarge)

(Click on image to Enlarge)

and similarly,to perform an STD (standard) enumeration,the following command is used :

Code:

./dnsrecon.py -t std -d


Using Google as an example again, our command would be:

Code:

./dnsrecon.py -t std -d google.com

The result as seen below in a standard enumeration :

BACKTRACK 5 R3 : dnsmap

1.  Another useful tool for information gathering is dnsmap....few of you guys may wonder of why to use a variety of tools for information gathering when most of them give more or less the same result.The answer lies in the fact that any kind of additional information can be a hole to exploit later...so in the stage of information gathering,it is always better to collect as much info as possible...so few quickies about what is the purpose of this tool...

-  Get IP addresses associated to each successfully bruteforced subdomain, rather than just one IP address per subdomain.
   
-  Bypassing of signature-based dnsmap detection by generating a proper pseudo-random subdomain when checking for wildcards.

-  Abort the bruteforcing process in case the target domain uses wildcards.
   
-  Ability to be able to run the tool without providing a wordlist by using a built-in list of keywords.
   
-  Saving the results in human-readable and CSV format for easy processing.
   
-  Improved built-in subdomains wordlist.
   
-  New bash script (dnsmap-bulk.sh) included which allows running dnsmap against a list of domains from a user-supplied file. i.e.: bruteforcing several domains in a bulk fashion.
   
[ Source : http://stylodj.wordpress.com/category/how-to-use-dnsmap-tool-backtrack-5-rx/]

2.  So to get to this tool...we need to follow the same route as we have been doing it in past...vide the information gathering sub menu as shown below :

Backtrack - Information Gathering - Network Analysis - DNS Analysis - dnsmap

 

(Click on the image to enlarge)

(Click on the image to enlarge)

 

 

3.   The basic syntax and switches for the tool are :

./dnsmap sitename.com [options]

and the switches are :

- w for wordlist file)
- r for regular results file
- c for csv results file
- d for delay millisec
-  i for ip's to ignore

4.   The screens below show the usage and execution part as it happens on the screen.

(Click on the image to enlarge)

(Click on the image to enlarge)

(Click on the image to enlarge)

5.    What we are attempting vide the command executed is to bruteforce all of the subdomains of certifiedhacker.com and saving them to a file called result. I have truncated the output since its very long and thus avoided.So I have only shown some part from the beginning and then as it ends.IN addition if one has a custom wordlist of subdomains he/she can use that as well simply by specifying the -w argument and then the path to the wordlist.So after the run is executed,the final results are seen in a manner shown below vide the screenshots :

(Click on the image to enlarge)

So as seen in the results above...we see there are 924 subdomains with their respective IP addresses.Though in the  screen shots above,we see a common IP address since it is a site for CEH testers.

In the screen shots above,the result file created is seen and read...so u can see the kind of contents that are stored in the file so generated....
