DATA CENTER's : THE INDIAN SCENE

1.   The phenomenal growth of data in India is rapidly evolving but where is all that data being stored?.....not a big deal to find out that all your FB profiles,your friends list, Google hangout circle of friends and all the enumerable social networking sites on the web stores your data across the globe but not in India....yes that's the truth...every bit of data that your profile holds is actually residing off shores ...what India might be holding is just logs of transaction via various monitoring eyes like CMS as discussed in last post!!!

2.   But actually what debar's any big company with a global presence to set up a data center in apna India...recently there have a explosion of many posts across the web o sphere citing the query of why is it so?...the reasons cited culminate on one reason and that's known as SECURITY....the non existence of "DATA PRIVACY LAWs" in India.....more over the fact that there is presently no existence of GIS routing of laid OFCs and cables maps though there are always plans and proposals for the future. The problem of underground OFC in and around NCR is such that companies are afraid to commit 100% availability of up time because your OFC can get damaged any time owing to so many under construction sites in NCR with dozers digging out OFC like Hollywood monsters.And these diggings are ever to continue coz still there are no laid down GIS mappings that can accurately predict the route and depth of laid out OFCs....and the most important I feel is the promise of state ELECTRIC POWER supply which is surely unreliable during any season....it is indeed surprising that power is still an issue in NCR towns!!!

3.   The future will always remains bright because we always have plans to remove all these problem areas but how and when remains a futuristic answer.GIS routing of cables is an imminent need and so are the data protection laws.By default as on date most of the data centres are coming up in Singapore.

"Singapore offers an ideal combination of reliable infrastructure, a skilled workforce and a commitment to transparent and business-friendly regulations" is how Google explains its choice of the city. Oracle cites "excellent telecommunications infrastructure and efficient, well-qualified manpower".

Much like India set up software technology parks to nurture its IT services and BPO industry, Singapore is setting up a 13-hectare Data Center Park and inviting companies from across the world. It already has some 20 data centre hubs and offers tax and other incentives.

Central Monitoring System : Another step in the Wrong Direction ?

1.    The month of "May" has become started with a "Will" from Indian Government.Now after so many still unresolved issues on Facebook posts and similar things in respect of issues of privacy,it has come up now with Central Monitoring System(CMS).The concept was placed in parliament  some time in December 2012 by the then information technology minister Milind Deora on which the government plans to spend Rs 400 crore and this would "lawfully intercept internet and telephone services"

2.  Now this means that everything we say or text over the phone, write, post or browse over the Internet will be centrally monitored by Indian authorities.Every byte of what is being exchanged by you over the net would be monitored.....but is it actually required?I have doubts per-se owing to the amount of further investment it would require.At a time when Big Data analytics is still maturing,investing so much on monitoring and storing some portion of it pan India would be a herculean task.The key points that I found interesting are dotted below :

- With the lack of privacy laws to protect Indian citizens against potential abuse,this would set another example of wrong feather in the cap.

- CMS has been prepared by the Telecom Enforcement, Resource and Monitoring (TREM) and the Centre for Development of Telematics (C-DoT) and is being manned by the Intelligence Bureau. 

- Without any manual intervention from telecom service providers, CMS will equip government agencies with Direct Electronic Provisioning, filter and provide Call Data Records (CDR) analysis and data mining to identify the personal information and provide alerts of the target numbers.

- The estimated cost of CMS is Rs. 4 billion. It will be connected with the Telephone Call Interception System (TCIS) which will help monitor voice calls, SMS and MMS, fax communications on landlines, CDMA, video calls, GSM and 3G networks. Is their any thing on Mother India Earth left to monitor?

3. Now I fail to understand that how Government expects to monitor cyber criminals by this CMS? Does government actually intend to find out the actual potent and dangerous Cyber Criminals or are they only interested in finding love affairs of local boys and girls!!!coz if the intention is former,would the cyber gang do it without tricks?...without encryption?...without spoofing?...when things like stegnography,TOR,Anonymous etc are still to be deciphered....the cyber crime would go on as it is.The focus should have been on analyzing of what is floating around rather then monitoring open text and messages.

4.  For example if a person with malicious intent,uses Whonix or anonymous kind of OS from a local cyber cafe and then places his message vide a steganographed image that is encrypted,is their any way that this can be deciphered?....technology does not exist today to decipher all this quickly ..still time is there when we reach such a stage....few months back in Dec 2012 when torrent was apparently blocked on directives from Govt Of India,anonymous group had given a open letter shared at http://www.geektech.in/archives/9924.

5. Well it is very clear that the decision makers in such moves are unclear on technological reality but also provisions for a scenario like WAR within....each step in such a direction has to be taken carefully because these are really critical.Additionally,outsourcing such moves to unreliable or may be foreign firms may become a serious threat.....

6.  Well at the end of the day,it is just my view per-sewhich no body is bothered...but the repercussions are serious to be avoided and ignored

Cloud Forensics:The State as on Date

1.   Cloud Forensics per se has got two powerful terms of today's buzzing IT World..... that's Cloud and Forensics...when traditional computing methods of forensics are still to mature...Cloud itself has a long way to go before the final matured model comes up...this combination actually refers to the world of CLOUD FORENSICS. NIST defines it as follows :

"Cloud forensics is the application of digital forensics science in cloud computing environments. Technically, it consists of a hybrid forensic approach (e.g., remote, virtual, network, live, large-scale, thin-client, thick-client) towards the generation of digital evidence. Organizationally, it involves interactions among cloud actors (i.e.,cloud provider, cloud consumer, cloud broker, cloud carrier, cloud auditor) for the purpose of facilitating both internal and external investigations. Legally it often implies multi-jurisdictional and multi-tenant situations."

2.   Today at NULLs meet,I got an opportunity to give this presentation on Cloud Forensics....the copy is shown below :

  Cloud Forensics

3. About NULL...please read about the community at their website at http://null.co.in/. The team is doing a great job for buzzing IT professionals,students,geeks,script kiddies(like me!!! :-). NULL boasts of an active security community where monthly meets and regular security awareness camps in various Institutions and Organizations are held. Basically a bunch of security phreaks who like to share their technical expertise and hacking skills with each other and spread awareness among the common people about the good, the bad and the ugly side of computers and technology. They believe that sharing the right technical knowledge leads to expertise and innovation.I joined them about 4 months back and have learned a lot in few meets that I attended!!!!!

Virtual Machines : Escape vs Introspection

1.   For last few years playing inside a VM ,I always used to wonder if it actually that safe surfing anything inside a VM...and that hardly anything gets in touch with the Host machine while we work with applications inside.Then I heard of two relative terms that are : Virtual Machine Escape vs Virtual Machine Introspection

2.  New to me but pretty old from point of view of existence....these are briefly explained below :

Virtual Machine Escape

Normally virtual machines are encapsulated, isolated environments. The operating systems running inside the virtual machine shouldn't know that they are virtualized, and there should be no way to break out of the virtual machine and interact with the parent hyper visor  The process of breaking out and interacting with the hyper visor is called a “VM escape.” Since the hyper visor controls the execution of all of the virtual machines an attacker that can gain access to the hyper visor can then gain control over every other virtual machine running on the host. Because the hyper visor is between the physical hardware and the guest operating system an attacker will then be able to circumvent security controls in place on the virtual machine.(Source : http://lonesysadmin.net)

Virtual Machine Introspection

Although virtualization isn’t new, the recent development of x86 virtualization products has revived interest in the virtualization market. This has led to the evolution of Virtual Machine Introspection (VMI) techniques and tools to monitor VM behavior. VMI tools inspect a VM from the outside to assess what’s happening on the inside.This makes it possible for security tools—such as virus scanners and intrusion detection system to observe and respond to VM events from a “safe” location outside the monitored machine. Depth of information is the fundamental benefit behind a concept called Virtual Machine Introspection (VMI). Its use within virtualized environments is absolutely crucial to effective risk mitigation at scale.(Source : |http://www.securityweek.com/vm-introspection-know-your-virtual-environment-inside-and-out)

So the basic difference is I think the route,in case of the former the need is to contact the hypervisor from inside and the latter shows the way out to get to know whats happening inside from outside perspective.....

Self Destructing E Mails : Receiver reads them only Once

1.   It has always remained a question for typical email users like u and me of how to send a self destructing E-Mail...an email that is read once and destroyed that moment like how about your office messages with vendors or love mails with your present Girl Friend/Boy Friend or u can imagine situations for such requirements....

2. Earlier it had been the disposable email solution and now there are many solutions that offer this particular requirement of Self Destructing E Mails.Below are few such sites and solutions :

- http://www.self-destructing-email.com/

Offers free trials last for two weeks or 25 emails (whichever comes first) and u need to register with it.It lets you decide what happens to your email after sending.

- https://privnote.com/


Privnote is a free web based service that allows you to send top secret notes over the internet. It's fast, easy, and requires no password or user registration at all.

Just write your note, and you'll get a link. Then you copy and paste that link into an email (or instant message) that you send to the person who you want to read the note. When that person clicks the link for the first time, they will see the note in their browser and the note will automatically self-destruct; which means no one (even that very same person) can read the note again. The link won't work anymore.(Courtesy : https://privnote.com/ )

- http://www.destructingmessage.com/

DestructingMessage.com is a free service which enables you to send a self-destructing message to someone. This means, once they read the message they will no longer be able to read it again after the timer has reached zero. This ensures your message is read by no one but the reader and all evidence of the message is erased. Messages are also anonymous unless you add any identifiable information to your message.(Courtesy : http://www.destructingmessage.com/)

4G drives to Indore in Cars and Motors via BSNL

1.   Indore is keeping its surfing grounds ready to welcome the 4G speed @ courtesy BSNL.Likely to be launched in some time May 2013......this will also be the first time some thing known as WiFi based "Internet on wheels" will be launched...but that is scheduled slightly later.

2.   Key features about the same :

 - 8 Mbps speed

-  Wi-Fi-based internet facility to motorists on move

-  Rough payment plans :
   
-   "BSNL's internet-activated car kit would be available in three ranges of one time payment plans that include : 
      - Rs 6500, 
      - Rs 27,500 
      - Rs 29,500

-  This will come along with a standard dial-up plan of Rs 250 per month.

3.  Here you go Indore'ites....all the best....but at the same time what props up is how will the gadgets handle this 4G speed....will the already held 3G mobiles and Tabs be able to take on the new G or are we awaiting new advertisements to lure us buying 4G devices!!!!

Browser Updates

1.   Without emphasizing on the need of why we should always keep our browsers updated,I am briefly bringing out here how to check and update your browsers.These browsers are invariably the most commonly used one's ...so I just updated few of them although the browsers exists in plenty!!!!

Firstly

To check the version of your Web Browser, Open the  Browser 

and do the following actions :

For Opera Browser

Click on “Main Menu > Help > About Opera”.

For Firefox

Click “Main Menu >Help> About Firefox.

For Internet Explorer

Press Alt+H and Click on “About Internet Explorer”.

For Apple Safari

Press Alt+H and Click on “About Safari”.

Secondly

To check whats the latest version doing the surfing....i advise two options...either you can simply ask google or check form the respective websites of the web browser...or another easy(but third party) way out is to check the latest versions available for download at http://www.filehippo.com/software/internet/browsers/

HIT WICKET & OUT- Microsoft Genuine Patch crashes WINDOWS 7

1.     This is some news from the corridors of Microsoft.A genuine MS patch released for Windows 7.The patch in the dispute is "Microsoft Security Bulletin MS13-036"

2.  Redmond from Microsoft's Security Response blog blamed the glitch on conflicts with third-party software:

We are aware that some of our customers may be experiencing difficulties after applying security update 2823324, which we provided in security bulletin MS13-036 on Tuesday, April 9. We’ve determined that the update, when paired with certain third-party software, can cause system errors. As a precaution, we stopped pushing 2823324 as an update when we began investigating the error reports, and have since removed it from the download centre.

Contrary to some reports, the system errors do not result in any data loss nor affect all Windows customers. However, all customers should follow the guidance that we have provided in KB2839011 to uninstall security update 2823324 if it is already installed.

3.   That means Windows 7 users should uninstall the security patch Microsoft issued on Tuesday because some PCs failed to restart after applying the update.....:-).Microsoft has advised users of Win 7 and Windows Server 2008 R2* to roll-back the patch.

4.   More about the patch here.Thanks http://www.theregister.co.uk/security/

GPS SPOOF!!!!

1.   Unlike the regular IT hacks wherein we keep seeing MAC spoofing,IP spoofing etc....what can one imagine if a GPS is spoofed.....:-)...can it make a plane land at a wrong coordinate?...YES!!!if it goes by the claims of a Iranian.

2. A US stealth drone was captured by spoofing its GPS coordinates, a hack that tricked the bird into landing in Iranian territory instead of where it was programmed to touch down...Phew..i bet u will read that again(Source :http://www.theregister.co.uk/2011/12/15/us_spy_drone_gps_spoofing/ )

3.   The 1700-word article cited an unnamed Iranian engineer who said he's studying the inner workings of the American bat-wing RQ-170 Sentinel that recently went missing over Iranian airspace. He said the spoofing technique made the craft “land on its own where we wanted it to, without having to crack the remote-control signals and communications” from the US control center.(Source :http://www.theregister.co.uk/2011/12/15/us_spy_drone_gps_spoofing/ )

4. Thats hell of a HACK...if it actually is!!!!!!salutes to the guy who could do it in real....now i wonder what all could land at forbidden places if it is really possible.....:-)

5. Thanks http://www.theregister.co.uk

FUDUNTU : Ubuntu + Fedora

1.     How about the best from Ubuntu and Fedora into one single OS?... that's rightly heard....the name is FUDUNTU....few things about this mentioned below :

- Website at http://www.fuduntu.org/

- Fuduntu aims to fit somewhere between Fedora and Ubuntu

- Fuduntu is a lighthearted and fun Linux distribution

 - Option to download directly as well as through torrent

- Fuduntu is optimized for on the go computing(good for Laptop and Netbook users )

- Improved battery life of 30% or more over other Linux distributions.

- The latest Fuduntu 2013.2 has LibreOffice, GIMP, Thunderbird, and other software that takes up a lot of space, approximately 10GB of disk space when installed. However, if you don’t need all that, try out the Lite version, where ISO weighs 800 MB and eats up 6 GB when installed.

2.   The download has started and if I feel it worth will show up with something about it...btw the looks are promising!!!!!

Whonix : Not just another ANONYMOUS OS!!!

1.     When u simply Google on "How to surf Anonymously on the web ? ".....u get a whooping 5,510,000 results in 0.19 seconds!!!!!but when u have such a plethora of options..how do u actually decide on which is actually worth? So there is TOR, then there is Anonymous OS.....did some one think Incognito?....:-)..so we have millions in the line!...so now what I am going to mention here is about Whonix OS.....few points about this as follows :

- An anonymous general purpose Operating System based on Virtual Box, Debian GNU/Linux and Tor.

- By Whonix design, IP and DNS leaks are impossible.

- Not even malware with root rights can find out the user's real IP/location.

- Whonix consists of two (virtual) machines.

-  One VM solely runs Tor and acts as a gateway, which we call Whonix-Gateway.

-  The other VM, which we call Whonix-Workstation, is on a completely isolated network.

-  Only connections through Tor are possible.

2.  When you download the image from the source forge site at http://sourceforge.net/projects/whonix/files/whonix-0.5.6/ you get basically three files.Two in the appliance format and one as a vmdk.So here is the basic diagram explaining the working architecture in WHONIX.

(Click on the image to enlarge)

3.   There is a small difference when we install this OS.Unlike the regular OSs wherein you get the .iso image of the OS and you install it in the typical manner,here the files you need to install are actually virtual appliances in form of .ovf and .ova format.How the installation is done is shown in the video cast below :

Twitter Session Cookie Vulnerability

1.    This one is pretty easy to show and understand..but the only thing not understandable is the fact that it actually exists even today.....so this one is about Twitter Session Cookie Vulnerability.I got to know of this at Null's delhi meet where Rishi Narang (http://www.wtfuzz.com/ )gave this demonstration of which I made a video cast subsequently and uploaded it here at your tube.

2.    In brief it goes like this...u login into your twitter account,an auth_token cookie is generated in the crowd  of various other cookies.Now this cookie only will be able to log you in your twitter account from anywhere across the web....simply watch how to exploit!!!!

3.   Thanks Rishi Narang @ http://www.wtfuzz.com/

Raspberry Pi : Whats this?

1.    Over last few months I have been seeing this term being mentioned in newly raised OS and applications...in the form like such and such OS/Application is Raspberry Pi compatible...so initially it did not  make me enthu enough to do some google/wiki on this..but when I read about Kali Linux being compatible with this Raspberry Pi...i thought I must see this when knowing it is just a click away...so goes like this for the first time readers about Raspberry Pi......

-  Raspberry Pi is a Credit-Card-Sized Single-Board Computer developed in the UK by the Raspberry Pi Foundation 

- Developed and introduced with the intention of promoting the teaching of basic computer science in schools....(sounds grt...we never had this...bugged with 8086 boards in our times...)

-  It has a Broadcom BCM2835 system on a chip (SoC)

-  Includes an ARM1176JZF-S 700 MHz processor 

-  Offers OEM Fiited 256 megabytes of RAM, later upgradable upto 512MB.

-  Does not include a built-in hard disk or solid-state drive, but uses an SD card for booting and long-term storage.

-  Extremely useful for Engineering Students for Projects Related to Robotics

2.    How does it look like ?

MODULAR DATA CENTERs

1.   Modular data center system's are a portable method of deploying data center capacity ie an alternative to the typical building set up like traditional data center.

2.   In general Modular data centers come in two types of form factors. 

-    Containerized Data Centers  fits data center repository (servers, storage and networking equipment) into a standard shipping container.A perfect example of this is the NEBULA@NASA.Few details of this are mentioned below :

How Nebula Looks Like ?

Features :

    -  40-foot long container

    -  Designed in consultation with CISCO

    -  built inside a FOREST container from Verari Systems

    -  Self-service platform built from open source software

    -  Each shipping container data center can hold up to 15,000 CPU cores

    -  Can accommodate files as large as eight terabytes 

    -  Can accommodate an individual file system of 100 terabytes

    -  Makes easier for NASA scientists to share large/complex data sets

2.   Another form of modular data center fits data center equipment into a facility composed of Prefabricated components.Example is HP’s version of this type of modular data center, which it calls Flexible Data Center.How this looks like is shown below :

Keystroke Dynamics Software : We all type UNIQUELY

1.     As on date Passwords are the most common form of identification but at the same time they are also the weakest. Though they are gradually being offered with replacements from the field of bio metrics,picture passwords and OTPs etc...still it will take its time before passwords are a forgotten past..now comes another cool option to identify uniquely....the concept is likely to surprise you if you have not heard of it before!!!!this is known as Keystroke Dynamics.The key points about this are bought out below in brief :

- Know as  Deepnet Security’s TypeSense keystroke dynamics software.

- TypeSense is an authentication solution based on the science of typeprint recognition that uses keystroke dynamics to accurately identify a user by the way they type characters across a keyboard. 

- Keystroke Dynamics technology extracts the distinctive characteristics found in typed sequences of characters, and creates a statistically unique signature from the typing patterns of a person. 

- These distinctive features include the duration for which keys are held and the elapsed time between successive keystrokes. This type of software runs in the background and constantly monitors your key stokes, learns your style, and can detect if your computer’s been hijacked.

- It’s relatively user-friendly and low-cost. 

- It’s mobile and can be used to access your online accounts from anywhere and can be easily integrated in your existing authentication infrastructure.

2.    But as on date the limitation is that typing style can vary greatly depending on whether you are tired, distracted, angry, medicated, or any number of other circumstances. These variations can cause the software to make false positive or negative errors.

3.    At DEFCON : 17, Andrea Barisani and Daniele Bianco demonstrated how to sniff keystrokes using unconventional side channel attacks. Wires in PS/2 keyboards leak information from the data wire into the ground wire which acts like an antenna. The leaked information about the keyboard strokes can be detected on the power outlet, as well as other wires on the same electrical system. By slicing open one of these lines, cutting the ground wire and attaching a probe, the line can be monitored and the signal isolated by filtering out the noise using software such as Scilab. The waves from the oscilloscope and the data can be streamed to the hacker’s computer where additional software is used to extract the victim’s keystroke information.Well..well ..well......there is no end!!!!

HP LaserJet Pro printers : Telnet Vulnerable

1.    A critical vulnerability discovered in few LaserJet Pro printers that could give remote attackers access to sensitive data. The latest breach expose by Germany security expert, Christoph von Wittich.In brief points below :

-   HP LaserJet Professional printers contain a telnet debug shell which could allow a remote attacker to gain unauthorized access to data.

-   Christoph von Wittich,the guy detected the vulnerability during a routine network scan of his company's corporate network.

-   Vulnerability could also be used for a denial-of-service attack.

-   As long as the printer is not connected to the Internet, this vulnerability should not cause much trouble for the end user,".

-  Effected printers include

      HP LaserJet Pro P1102w
      HP LaserJet Pro P1102
      HP LaserJet Pro P1606dn
      HP LaserJet Pro M1212nf MFP
      HP LaserJet Pro M1213nf MFP
      HP LaserJet Pro M1214nfh MFP
      HP LaserJet ProM1216nfh Multifunction Printer,
      HP LaserJet Pro M1217nfw Multifunction Printer,
      HP LaserJet Pro M1218nfs MFP
      HP LaserJet Pro M1219nf MFP
      HP LaserJet Pro CP1025nw
      HP LaserJet Pro CP1025nw

2.    Now for HP something like this is not new....even in past about 2 years back in dec 2011,a vulnerabilty was discovered wherein "Print of one malicious document can expose your whole LAN".

3.    In-fact I discussed a past case at Feb 2012 last year here....3 months after that happened.HP seems to be busy with printing only....high time they start focusing serious work on security aspects too!!!!

4.    Thanks THN....The Hacker News

Attacks@Image WaterMarking

1.    We keep exploring new grounds but also without realizing the pits it offers,we start playing games on it.Such is the world of IT,we keep discovering so many new technologies to strengthen and exploit for our use and we keep ourselves vulnerable!!!!

2.   Without wasting more words,this post would briefly mention about Image water marking and the type of attacks it remains vulnerable to.So first whats Image Water Marking??...an easy way to describe digital watermark is simply comparing it to a traditional paper watermark or a power point water mark which most of us might have even used at some point of time.Like Traditional watermarks offer proof of authenticity by being imperceptible, digital watermarks offer a way that allows a computer to read the mark but not by the human 6/6 eye....there are actually four essential parameters which are commonly used to determine the quality of water marking these are :

- Robustness

- Imperceptibility

- Payload 

- Security

3.   Now each of these parameters has a unique characteristic that makes the purpose of image water marking strong and adaptable.So when we speak about attacks on image water marking...the attacks again are classified as :

- Image Compression Attack : Primarily used to reduce the size of image in transmission.The original image remains most of it that it was but requires lesser bandwidth to move.

- Image Contrast Attack : To a human eye a slight change in contrast of colors makes a huge difference in overall perception

- Cropping Attack : A part of image gets cropped from original

- Re sizing Attack : The image gets re sized from the original coords

- Rotation Attack : A simple clockwise or a anticlockwise attack would rotate the image from its original coords

Another categorization of the image water marking attacks contains four classes :(Source here : Abhishek Goswami)

Removal Attacks : Aim at the complete removal of the watermark information from the watermarked data without cracking the security of the watermarking algorithm

Geometric Attacks : Do not actually remove the embedded watermark itself, but intend to distort the watermark detector synchronization with the embedded information.

Cryptographic Attacks : Cryptographic attacks aim at cracking the security methods in watermarking schemes and thus finding a way to remove the embedded watermark information or to embed misleading

watermarks.

Protocol Attacks : Aim at attacking the entire concept of the watermarking application. This type of attack is based on the concept of invertible watermarks. The idea behind inversion is that the attacker subtracts his own watermark from the watermarked data and claims to be the owner of the watermarked data. This can create ambiguity with respect to the true ownership of the data. 

Power of PING

In our respective interactions with various networks accessible to us.....as administrators we keep pinging so many IPs for testing the connectivity at various times like ping 192.121.23.1 etc....and we get a response...but ping it self has so many switches that most of us hardly use......i came across a chart today that in a summarized form tells the switches of ping command with examples and a brief explanation.....sharing here with you...thanks http://www.activexperts.com

ping -c count	ping -c 10	Specify the number of echo requests to send.
Ping -d	ping -d	Set the SO_DEBUG option.
Ping -f	ping -f	Flood ping. Sends another echo request immediately after receiving a reply to the last one. Only the super-user can use this option.
Ping host	ping 121.4.3.2	Specify the host name (or IP address) of computer to ping
ping -i wait	ping -i 2	Wait time. The number of seconds to wait between each ping
ping -l preload	ping -l 4	Sends "preload" packets one after another.
Ping -n	ping -n	Numeric output, without host to symbolic name lookup.
Ping -p pattern	ping -p ff00	Ping Pattern. The example sends two bytes, one filled with ones, and one with zeros.
Ping -q	ping -q	Quiet output. Only summary lines at startup and completion
ping -r	ping -r	Direct Ping. Send to a host directly, without using routing tables. Returns an error if the host is not on a directly attached network.
Ping -R	Ping -R	Record Route. Turns on route recording for the Echo Request packets, and display the route buffer on returned packets (ignored by many routers).
ping -s PacketSize	ping -s 10	Sets the packet size in number of bytes, which will result in a total  packet size of PacketSize plus 8 extra bytes for the ICMP header
ping -v	ping -v	Verbose Output. Lists individual ICMP packets, as well     as Echo Responses

BACKTRACK 6.0 aka KALI LINUX

1.      This will  be a surprise news for those who have were updated till Backtrack 5R3....the same team has come up with some thing more powerful thats named...KALI LINUX....:-)....and not BACKTRACK 6.0......few key points about KALI....

-    Based upon Debian Linux, instead of Ubuntu 

-    New streamlined repositories synchronize with the Debian repositories 4 times a day.

-   Another great feature introduced is that, because of Debian compliant system, it is now able to Bootstrap a Kali Installation/ISO directly from Kali repositories. This allow any user to easily build their own customization of Kali, as well as perform enterprise network installs from a local or remote repository...now start distributing your own ISO....

-   More than 300 penetration testing tools, completely free, Open source, Vast wireless device support, GPG signed packages and repos, Multi-language, Completely customizable make this distribution one of the best available masterpiece of  hacking community.

-    Once again, default root password is same “toor“, you can download Kali Linux here.

2.    My download will start tomorrow morning....will keep me busy for few days and hours...:-)

DRDO HACKED : NO....YESS...NO...YESS!!!!goes on...

1.    Now nothing new about this news....its just another hacking news among-st the millions of hacking news and scrolls daily....but it has become an eye popper because it has the word DRDO in it..... that's the Defence Research and Development Organisation.

2.   Though DRDO straight away denies it that it can never happen(whats the basis behind is a well guarded secret...)...but Pawan Duggal,a known Cyber Expert says that never in the history of "India Hacked" past has such voluminous data transferred and resided in servers outside the country borders.....video down here

and more details at http://zeenews.india.com/videos/china-hacks-drdo-systems_20156.html

and http://timesofindia.indiatimes.com/india/DRDO-computers-hacked/articleshow/18955837.cms

3.    The hacking is suspected to have been carried out by Chinese hackers and there are fears that some sensitive information could have been compromised.When asked about it, Defence Minister A K Antony said, "Intelligence agencies are investigating the matter at this stage and I do not want to say anything else."

Commenting on the issue, DRDO spokesperson Ravi Gupta said, "As per our information, no computer or network of the DRDO has been compromised."(Offcourse they have records to prove that all sentries and guards were on duty at the moment hackers claim they hacked DRDO....pun intended SIR!!!!!)

4.     Today things in context of Cyber Security at national level stand at a very critical juncture...infact I feel that juncture is past now....we are already late...but still we read and hear that Cyber Security Policy of India will arrive soon.....(i know cut paste also takes time....pun intended!!!!!)..READ HERE

5. India I am sure will keep busy with hiding elephants......jantar mantar.......elections...2014....italy guards.....bhagwan etc etc...but if the priorities don't change the order soon...India will be backed up and downloaded in some other country sooon....it will be veri sad...we are one of the leaders in IT industry....specially software but we have not been able to exploit this potential for in house strengthening...we are all concerned for individual growth...vo subah kabhi to aaayegi....vo subah kabhi to aaayegi!!!!!

Graduating from Fedora 18 to Ubuntu 12.10

Had waited for months to see Fedora 18 release and then finally getting a hold of it last month.....was indeed a sad experience....the common bugs that I found in routine working with the Beefy Miracle included TOO SLOW and issues with installations of common third party applications ...everi one coming up with some dependency issue.....so finally downloaded 12.10 Ubuntu yesterday and now working on that...for me its bye bye Fedora 18....but now I am fighting skype cam installation issue with Ubuntu......no luck till now

Browser fight continues : CHROME continues topping too!!!

1.    Not long back we all have seen or might have experienced when violent and pornographic images were fed across facebook profiles of FB friends without the knowledge of the online FB user when he used to simply click on a tempting link!!!!All that happened owing to so many malwares but the exact launching vulnerability was indeed in the BROWSER!!!!!

2.    The openweb is full of options for seemingly good browsers viz Mozilla Firefox, Google Chrome, and Microsoft’s Internet Explorer. But who is the best?.....though when u google u find so may individual claims but third party tests are always welcome on such issues...specially when they have huge evidence to support....like few years back I posted on ACID3 test for the browsers...this one comes from Accuvant...and its actually huge in terms of a conclusive report that's 139 pages in toto......:-)

3.   The full report can be accessed by clicking here...so the Accuvant study revealed that Chrome ranks as the most secure web browser when compared to Internet Explorer and Firefox. Interestingly, German government named Chrome the most secure browser, perhaps lending weight to the study. 

4.   The criteria to test these browsers included factors like ASLR,GS,Sandboxing,JIT Security etc as shown below :

DAEDALUS : Monitor Cyber-Attacks Realtime 3D way

1.    Whether it is the Die Hard ver 4.0 movie scene or Mission impossible recent one or any hi tech cyber movie....we have have all seen the mega sized dark halls equipped with gigantic screen displaying all sorts of real time ridiculous hacker related information and monitoring tracks of the enemy or the protagonist....so how good or effective or even real are these in the real sense....can some thing like these seen and shown over years on the silver screen be REAL....yesss...first watch this video and then read few points as bought out below :

2.   A company in Japan named NICT just unveiled a system dubbed Daedalus that will revolutionize the way companies and even countries can monitor cyber-attacks in full real time 3D representation.The key features about this is bought out as below :

- Daedalus is not only a way to monitor cyber-attacks from outside, but also what’s going on inside it. 

- So if someone receives an email with a virus for example, the system can quickly identify the IP address that is currently spreading it and shut it down immediately.

- The NICT recently gave a demonstration and tracked 190,000 IP addresses in real-time  

- Daedalus can monitor multiple entities at once and get notified, once again, via 3D graphical representation when a cyber-attack occurs. 

- This is not only when it happens, but instantly where it happens and who the attacker is.

3.      So when the objective is envisaged on a higher scale....ie the complete global internet monitoring.....will this be the start to control spam(90% of mails exchanged on the web is spam)....or will this be able to control cyber attacks across.....well not a bad start to a start whose objective is MISSION IMPOSSIBLE type...another thing that may have come to your mind is about the name...of all what does Daedalus mean?...well in Greek mythology, Daedalus means "Clever Worker"

SOLVED: VLC installation Issues : FEDORA 18

1.      After installation of the spherical cow Fedora 18 64 bit on my machine,there was this popping message while i tried installing the VLC media player :


GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-x86_64

(CLICK TO ENLARGE)

2.    But this could be solved as shown below :

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-18.noarch.rpm'

and now do 

yum install vlc

Like in PATCO case,DO OUR BANKS GUARANTEE CYBER SECURE ACCOUNTS ?

1.   Suppose you have a SBI or HDFC or ICICI Bank or any bank account and you keep doing your regular transactions via their internet banking services like you pay your electricity bills or your mobile or phone bills etc.So ALL is WELL till every thing is going as expected.But then one day you realize that there were transactions that happened without your knowledge or worse some money gets siphoned off without your permission.....Now a journey starts......wherein the account holder will keep expediting with bank of what happened,why it happened,when will he get his money back???? and on the other hand bank will keep trying to prove that it is you or the account holder who acted irresponsible in his transactions and thus became the victim....the typical tu tu....mein mein.....

2.    Keeping this typical story in the background,now just think that did u ever make a attempt to know of what bank standards are maintained in respect of IT Security infrastructure....does bank conduct third party audits seriously?..... in fact the list to know answers to all these questionnaire pertaining to IT security issues of the bank will end up getting complex which would go beyond the understanding level of a typical user...so the simple question is WHO GUARANTEES A SECURE IT INFRASTRUCTURE for a BANK?...is it the bank itself that says " I am secure " or some one else has some authority or some standard that guarantees security....ie Can your savings bank account ever be guaranteed for being HACK FREE?Although the immediate answer in the current setup is sadly "NO"...but there is good news here....for this u need to read this article on " PATCO FRAUD CASE DISPUTE "

How to find if latest kernel version is running on my Linux system?

Simply type in these commands and the result in both the cases should match.....


rpm -qa kernel |sort |tail -n 1

uname -r

Note: If you got kernel update or run older kernel than newest installed then reboot:

reboot

Output of each commands version numbers above should match....for example in my case the out put is shown as below :

[duqu@localhost ~]$ rpm -qa kernel |sort |tail -n 1

kernel-3.6.10-4.fc18.x86_64

[duqu@localhost ~]$ uname -r

3.6.10-4.fc18.x86_64
