Exploring exif data, how did it read and manipulated ?

Exchangeable image file format (Exif) is a specification for the image file format used (mostly) by digital cameras. Exif is metadata hidden behind an image/audio/video created by device while image being taken, exif data is introduced by the Japan Electronic Industries Development Association (JEIDA) with purpose to encourage interoperability between imaging devices. learning exif data is part of digital forensic studies, trough exif data we learn when was image is being taken, what device is use to take, and what is being manipulated.   

What information inside Exif data ?
Exif usually contain of supporting information of file, that information can be [1] Date and time information, digital cameras will record the current date and time and save this in the metadata.[2] Camera settings, the information of camera setting includes static information such as the camera model and make, and information that varies with each image such as orientation, aperture, shutter speed, focal length, metering mode, and ISO speed information. [3] A thumbnail for previewing the picture on the camera's LCD screen, in file managers, or in photo manipulation software, if a file was being manipulated the data will be shown here. And the last information of exif data is [4] Descriptions and copyright information, this case not created by imaging device but it created by application like a photo editor.

How to read exif data on Ubuntu Linux ?
Reading exif data is quiet simple in ubuntu, we have application called exiftool (also available in windows/machintos) which can help us to read, write, and edit metadata on exif data. to install exiftool we can use the synaptics package manager or go to official exiftool website to download and install. exiftool is command-line application which run on terminal, to running this application we can use this syntax synopsis.

exiftool [OPTIONS] FILE

as case studies, we will try to use this application to analyze image then see what hidden information behind them, we have two identic image and one which of them is has being edited by image editor application, let see what goes in their metadata :

raw_image

edit.jpg

Through a bare eyes we have same image above, did exif give a same explanation ?, notice the data below

Exif data of raw_image

Look, we can see hidden information behind the image, we have some particular information such us the image is being taken in 27 september 2009, using device Canon PowerShot A590 IS, using iso 400.

Exif data of edit.jpg

based on data above, 2nd image (edit.jpg) is not original, edit.jpg was being manipulated in 31 July 2010 using Adobe Photoshop. Some potential information can be found from exif data if we notice carefully, yes.., practice make perfect.

How to manipulate information on exif data ?
yes, we make right statement when we decide that exif could be a potential evidence of computer crime, but one point must be remember is exif data "can be manipulated", simple example below would describe it. We use application named jhead, jhead  is  used  to  display  and manipulate data contained in the Exif header of JPEG images from digital cameras. By default jhead displays the  more  usefull camera  settings  from  the  file in a user-friendly format. We have conclusion that jhead have ability to delete exif or make 'fake' exif data. To get complate information and option of jhead you can visit this link. We try to remove exif information of Edit.jpg above using option [-purejpg] in jhead, then see what different : 

Edited exif data

we look pretty different of exif data now, some information is 'disappear', simple example above prove that exif data could be a potential evidance but not 'Absolute' because exif data can be manipulate (remove or edit). Jhead is strong application, they can do much with exif data, if you interesting with this application i suggest you to visit this website.

Introduction of Backtrack for Computer/Digital Forensic Tools (Part II)

Continuing our discuss in introduction backtrack for computer/digital forensic tools part I, in this part we will try to dig how deep is backtrack have a potential source as computer/digital forensic tools. Backtrack is a linux distro which can put many kit into one vessel and collaborated each other, this is an excess of backtrack which not owened by other. Talking of computer/digital forensic tools we have too clasify some parts of tool into different part besides of it's use, after i read some article with the same topic of computer/digital forensic many of them classify it's into five major classification, that is ..

1. Data Acquisition
2. Data Recovery and Carving
3. Meta Data Analysis
4. Network Forensic
5. Log File Analysis

After looking at the five major clasification of digital forensic tool above, we agree that Backtrack 4 have all candidate to meet all requirement, let peel of one by one.

Data Acquisition

Data Acquisition is set of application which is responsible to interrogate harddrive and get neccessary information from them, in this field we have some particular job like make an 'identic' copy of harddrive then analyse them without ruin the original evidance and doing File System Interrogration jobs even it NTFS/FAT/EXT3 or Other. To do a data acquisition jobs in backtrack we have such application Advanced Forensic Format Library (afflib), Automated Image and Restore (air-imager), dd, dcfl-dd, lsof, guymanager, acidlab, and RDA. All applicaton mentioned can be installed using backtrack package manager. 

Data Recovery and Carving
The Data Recovery tools is set of application which responsible to get erase data back, analyzing hidden and erase partition, and fixing a broken block of filesystem. Data carving is extracting data (files) out of undifferentiated blocks (raw data) for the purpose of file identification. We have such application like ddrescue, foremost-menu, scalpel, xpilco, allin1, and autopsy In backtrack to do Data Recovery and Carving.

Meta Data Analysis
Meta Data Analysis is looking for hidden variable behind the file and data, to do a meta data analysis we need some application which can do activity like dissassembling a file (ducument/image/audio/video) and get hidden variable like when was file last accessed, when was it modified, or simeting like when was file has been created and using what tools it's has been created, looking for meta data analysis tool we have application called libtsk1, vinetto, also image and video editor (gimp,fspot,audancity) in backtrack. 

Network Forensic
Network Forensic tools is not much different if compare with network security program, cause that is have real same algorithm eventhough we do the reverese enginnering ones. Network forensic tools covered such jobs like make an analysis of network traffic, captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging, identification network error, sniffing and loging network activity in various port (telnet, ssh, imap, pop3, smtp) and many more. This part is the specialization of backtrack, we have many network security/network forensic tools in this distro that can be use, this is the following of them : netcat, netflow, tcpdump, kismet, wireshark, and very lot of stuff.

Log File Analysis
There are components of files that may have evidentiary value including the date and time of creation, modification, deletion, access, user name or identification, and file attributes. computer-created files (log) which can be potential evidence are backup files, log files, configuration files, printer spool files, cookies, swap files,hidden files, system files, history files, temporary files,link files, event logs. All application program in every computing work has always make a log file which can be a perfect evidence if we're dig correctly, to do such log analysis job in backtrack we have such application aneteater, wflogs, sma, nulog, awstat, galleta-menu, and maltego.

Eventually we have finish our discuss in Introduction of backtrack as computer/digital forensic tools, looking to our conclusion before now we have realy agree that Backtrack linux have some potential resource to be reliable digital forensic tools. In other occasion we will discuss one by one that application above to get clear explanation how to make it and use it wisely.

What would you ask if you met Mr. Mark "Ubuntu" Shuttleworth (Founder of Ubuntu Project) ?

Who didn't know Mr.Mark Shuttleworth, this people is equal with the famous 'Mark' of the year besides Mark Zuckerberk (Facebook Founder) and Mark Mullenweg (Wordpress Founder), Mark "Richard" Shuttleworth was born in 18 September 1973, he is the Man behind Ubuntu, the Man behind Canonical, the Man behind HBD Venture Capital, and also the first African space traveler. Mark "ubuntu" Shuttleworth is an African entrepreneur with a love of technology, innovation, change and space flight. He start his debut by founding Thawte (is acompany specialising in digital certificates and cryptography) Then Founding The Shuttleworth Foundation (is a non-profit organisation that accelerates social innovation in Africa with a particular focus on education.) in 2001, One of important point we would know about Mark "Ubuntu" Shuttleworth is he not only work for the future of open source software, but also for the future of learning, South Africa, and the world at large.

Mr. Mark Shuttleworth as keynote speaker

This article will not discuss of biography or history of Mark Suttleworth, we start this discuss by imagine that "How about we meet Mr.Mark shuttleworth, what would you ask if you have just one question" just like joan osborne said. Some people admire to ubuntu, Some people have same interest with Mr.Mark Shuttleworth did or someone else have a same problem like affrican which Mark Shutterworth Foundation concentrated.

if it would happened to me of course i will not ask question like some movie in bollywood "Hello Mr.Mark my name is Khan and i'm not terrorist, what about you ?" or something like "Who will be the next president if this country ?". Eventhough it would be less if just one question, i will start explain my purpose with, besides of data in google we know that ubuntu is become very popular lately and the data said that 'indonesia' is the top of region where  ubuntu is become popular, then my question is

When will connoical & Mr. Mark  come to indonesia to held ubuntu release party like other country has ?

Every people have own purpose to ask, every people have own reason to do, we think it would be gratefull if Mr. Mark Shuttleword read this :D, and now how about you ?

Introduction of Backtrack for Computer/Digital Forensic Tools (Part I)

Computer/Digital Forensic has become popular lately, start form Bank Robbery, Hacking/Cracking/Hijacking up to popular scandal on the artist sex tape using this method to find the truth. Computer forensics is the generic name that we use for the analysis and reporting on our findings from the forensic analysis of all computer or digital-related media. This not only includes PC/Laptop or Server hard drives but also other storage devices such as USB drives, MP3 players, memory cards, SIMS and data gathered via network analysis. Computer/Digital Forensic is a part of computer security, computer practitioners (computer analist/computer expert)clasified this method into offensive security action which usually did after insident. Digital forensic actualy do after computer criminal insident, common Digital forensics cases include:

drug dealing, internet misuse, pornography in the workplace, rape, illegal downloads, IP theft, paedophilia, murder, virus/malware infection, fraud, email analysis, data recovery, contract negotiations, e-discovery, peer-peer activities, spyware analysis, spoofed and threatening emails, document tracking

Talking of computer security tools not separrated with the most popular computer security tool of the year 'backtrack', backtrack has so many tools and application to do such security penetration testing, security attack and also computer security action for computer/digital forensic purpose. When we first boot up the new Backtrack 4, you might have noticed something slightly different that is ...

We can see that backtrack has include 'computer/digital forensic' as main cause existence of this distro

All types of operating systems can be analysed, from DOS and Microsoft Windows-based, through to MAC, UNIX variants, and those utilising more obscure systems. If the data is stored electronically, then it can probably be forensically analysed. From other wellknown literacy, There are five basic steps to the computer forensics:

   1. Preparation (of the investigator, not the data)

   2. Collection (the data)

   3. Examination

   4. Analysis

   5. Reporting

Which one must be analyzed ?

Computer/digital forensic tools is work to analyze a digital evidence, in the computer world we know that many device can be potential evidence which help computer analyst find the truth, here some potential evidance can be found :

       images, time and date stamps, removable cartridges, memory card, video, sound

Evidence can also be found in files and other data areas created as a routine function of the various types of computer operating systems. In many cases, the user is not aware that data is being written to these areas or files. Passwords, Internet activity, deleted files and temporary backup files are examples of data that can often be recovered and examined.
Backtrack linux have some potential resource to be reliable digital forensic tools. Backtrack have so many tools to help computer analyst to do some jobs like Examine drive, Analizing drive, Recovery dive, Vulnerabilities check, Penetration testing, and File interogration. Actualy this is the end of part I, we will continue this diccuss as soon as posisble using title "Backtrack for Computer/Digital Forensic Tools Part II", See u there ..

How to build reliable backup and restore system using rsync

Data is an important asset owned by company, data which is the raw of information require a necessary method how keep and preserve well, to reduce the impact of damage and data loss which possibility occur. Backup and restore procedure that a part of disaster recovery planning is one of the way that can be perform to reduce the impact of data disaster. From statement above we can conclude that  all of us need to ensure all important data of us or our company must be backup well. And now the answer is, how to design a reliable backup and restore system which can run on linux ?
To design or build backup and restore system we must have reliable tool to move data from source to destination via network, lucky we have rsync running in linux operating system. Rsync is such application which can move data (use incremental method) from one computer to another through ftp, scp, and ssh, rsync is small and multi perform application which can be use as server or client.  

Step 1
First time before you start build a system we must describe what system we want to build otherwords describe fungsional and non fungsional sytem requirement then design the layout of application.

Step 2
Step 2 we must prepare our system and install all required application, for this section for required application we can install ssh-server, mysql5.0-server, and rsync as main application. with no less important  don't forget to describe supporting factors such database design, working directory, and previllages user to run.

Step 3
Important part of backup and restore system is script to copy/move data form one computer to another, for this section i have provide some script write in bash language that found in internet then modified it then you can download by following this link. Maybe you can't use script given directly, you can modified that script and fit to your system.  I will give explanation to have clear illustration, you can open the script while read this.

• This script is running by cron, work valid by parameter save in file (/var/www/LIBT/exec/. That file configuration contain of  backup parameter such us name of session, rsync parameter, source and destination mechines. this file writen by application interface (you can build by your self) which help user to descibe backup session they want to build.

• This script work to manage/colaborate supported application like rsync, mv, cp, mysql, chmod, chown, etc.
• Plot of backup procedure of this script is  -- [read configuration file] -- [check input parameter given] -- [decide local/remote backup] -- [perform backup/rotate backup] -- [write log/give feedback]-- .This script can due incremental backup so if you have running the same backup before, system will save previous data backup and make a new copy of data backup, this important procedure can be use to implemented restore point.
  
  
  

Step 4
Test the script you build, the only way to test the script is try to implemented backup betwen two computer. Rsync is wells work with SSH, so i suggest that you chose SSH as media backup. Before start to backup you must consider  both of computer is free to access one to another, use ssh-key to make it happend, here step to make ssh-key between two computers. 

• First log in on A as user a and generate a pair of authentication keys. command : ssh-keygen -t rsa.

• Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine) command : ssh b_user@ | mkdir -p .ssh. 
• Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time, command : cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
• Try to log on to computer B from computer A, if the machines not ask any password you have success implemented ssh-key and your system is ready to test. 

Step 5 
If all testing has complate, Verify data of backup you have got. if all data is identic (similar) to source data we assume that we have successfull reaserch and ready to the next step (restore). 

Step 6
Restore procedure is desperately needed backup information of previous procedure (backup), if you consider to add restore tool as additional feature of your system, you must write down all action, time execution, and all additional information needed to the database so you can use it then. Some infomation you have to record when doing backup is source and destination mechines (ip address), time of backup (to get restore point), path folder where you have save the data backup, user and password or ssh-key.

Step 7
If all step is clear and successfully tested, i think you have build a reliable backup and restore system under linux. please fell free to contact us if you get any problem.

Free Download Cisco IOS Images for GNS3/Dynamips/Dynagen

Cisco IOS is an operating system by Cisco System which offer a better way to build a managable netwok interconnection, this operating system used on the vast majority of Cisco Router and Cisco Network Switch. As article i wrote in ubuntubuzz, here the list of Cisco IOS can be used for GNS3, Dynamips, or Dynagen :

Dear visitor,
We were sorry that we can't provide free download cisco ios images on this page (anymore), we afraid of breaking "Free Open Source Software" rule and violate some cisco authorities about legal software, very unfortunate that Cisco does not provide any flexibility to CCNA, CCNP, CCIE students to learn more about cisco Routers/Switch by provide a free IOS For Download. 

For complete instruction the way to use Cisco IOS for simulating a Cisco Router and Cisco Network Switch, see my previous article here.

GNS3 : Running Graphical Cisco Network Simulator On Ubuntu Linux

Cisco Network is well perform network equipment and platform, there are many companys in the world entrust their network being handle by this instrument. A lot of advantages we get if we know much about this network equipment eventhough it's not simple way to learn more about all Cisco Netwok familly. 

Not only Microsoft, Java, or Oracle, Cisco System provide Cisco Netwok Career Certifications which provide profesional IT certification for Cisco System Product such us CCNA, CCDA, CCNP, CCDP, CCSP, CCVP, and CCNA Security. There are five levels of certification: Entry, Associate, Professional, Expert, and Architect, as well as seven different paths, Routing & Switching, Design, Network Security, Service Provider, Storage Networking, Voice, and Wireless.

My personal opinion Cisco Netwok Career Certifications is not cheap, but it's very important for profesional network engginer to have it.  get the best preparation is the best effort we can do. There are many network/cisco simulator in a market as we know Boson, Networksim and All official Network simulator form Cisco System that can be install in our desktop and we can learn from it.

GNS3 is sort of Graphical Network Simulator, GNS is Free/Opensource Cisco Network Simulator running on Ubuntu and Linux familly. GNS3 is other form of Dynamips and Dynagen which older cisco simulator for linux running on terminal. To complate simulations, GNS3 is strongly lingked with :

• Dynamips, the core program that allows Cisco IOS emulation.
• Dynagen, a text-based front-end for Dynamips. And
• Qemu, a generic and open source machine emulator and virtualizer.

That mean to start using GNS3 we must install application above, if you running ubuntu the fastest way to install GNS3 is go to System > Synaptics Package Manager > (type GNS3 as keyword) then Apply and install, all application needed to run GNS3 is automaticaly installed.

GNS3 Screenshot

Before GNS3 is ready to use, download Cisco IOS from this page first then add Cisco IOS to Dynagen IOS library. Here they are Step By step how running Cisco Network Simulator on Ubuntu Linux : * Continue with following step when you have finished installing GNS3.

• Download Cisco IOS in this page (chose only required IOS)

• Open GNS3, than add Cisco IOS to Dynagen IOS library. To add IOS to Dynagen go to menu edit > IOS images and Hypervisors, browse the images and fill all required information.

GNS3 Topology Example

• Draw the topology you want to bulid by drag and drop router logo in the left side of GNS3 to the center of topology area.

• Configure the network, Configuring network can be start by connecting one router to another by the connector (Giga etheret, ATM, Fast ethernet), to edit router properties like RAM, Additional Pheriperal in Slot, Name or other can be accessed by right click the router then chose 'configure'. Just like the actual Cisco router we can telnet (remote) the router and doing all Cisco task and job like the real ones.

Router Properties

Router Properties

• to finish the topology, after all router has been configured well, check topology interconection by router utillity like 'ping' or 'traceroute' from one router to another.

And now we can start a better preparation to join profesional network certification from Cisco System, to expendite the practice download some Network Topology here.

Ubuntu One is the personal cloud service that simplifies your digital life. Ubuntu one is such application bundled with Ubuntu OS which help us to keep in touch by sharing, buying, searching, manage file, data or music with other people using internet, ubuntu one serve new experience of data sharing. Imagine buying music and getting it delivered to the computers of your choice or synchronizing your files and notes and accessing them from anywhere. Or consolidating your computer and mobile phone contacts and safely sharing documents and pictures with them. Ubuntu One can already do this and more (https://one.ubuntu.com/).

To start using this service we can go to http://one.ubuntu.com/account then create new account (user & password) and follow the instructions or follow theh directions in this link.

I thinks everyone agree if i call ubuntu one as a new way of digital data sharing, here there are some ubuntu one feature from the official website that underlaying my statement above :

A personal cloud to store, sync, and share your files. 
Automatically store and sync your documents, images and media with your personal cloud and your other computers. Share folders with project collaborators or publish files with the world
Synchronize your bookmarks 
Ubuntu One Bookmarks (also called the Bindwood project) automatically synchronizes your Firefox bookmarks with your personal cloud and your other computers. You don't have to change anything about how you use bookmarks today because Ubuntu One works behind the scenes to keep everything in sync.  
Full Control with tomboy notes.

Ubuntu One Notes is integrated with Tomboy, the notes application in Ubuntu, and automatically synchronize with your personal cloud and your other computers. You can also use the Ubuntu One website to browse and modify all of your notes.

How to tell google application when your domain has changed

Domain is important part of website or blog, domain could become a powerfull brand if we made seriously. There are lot of service whom provide free domain and hosting for us to make a new website and blog such wordpress and blogger, but in a same time they don't serve a niche domain for us to made a powerfull brand for our website or blog. As i read in blogoscoped.com there’s a few things you might need to adjust in the different Google apps when changing/moving to a new domain from wordpress/blogger to comercial domain (for eexample  we would change blogger domain from old.blogspot.com to new.com):

• Add the new domain in your AdSense channels
  Choose AdSense -> AdSense Setup -> Channels -> URL Channels -> Add new URL channels
• Change your reply-to address in Gmail, if you used a redirect
  Choose Gmail -> Settings -> Accounts -> Edit info
• Change your signature in Gmail, if you used the old domain name in it Choose Gmail -> Settings
• Add your domain into the Google Webmaster Tools
  Choose Google Webmaster Tools -> Add Site (you then need to verify your site by e.g. uploading an HTML file)
• Tell Google Webmaster Tools your preferred domain, and allow advanced image functionality
  Choose Google Webmaster Tools -> [your domain] -> Preferred domain/ Enhanced image search
• If you’re using the AJAX Search API, generate a new key to work with your domain
