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 countping -c 10Specify the number of echo requests to send.
Ping -dping -dSet the SO_DEBUG option.
Ping -fping -fFlood ping. Sends another echo request immediately
after receiving a reply to the last one.
Only the super-user can use this option.
Ping hostping 121.4.3.2Specify the host name (or IP address) of computer
to ping
ping -i waitping -i 2Wait time. The number of seconds to wait between
each ping
ping -l preloadping -l 4Sends "preload" packets one after another.
Ping -nping -nNumeric output, without host to symbolic name lookup.
Ping -p patternping -p ff00Ping Pattern. The example sends two bytes, one
filled with ones, and one with zeros.
Ping -qping -qQuiet output. Only summary lines at startup and
completion
ping -rping -rDirect Ping. Send to a host directly, without using
routing tables. Returns an error if the host is not on
a directly attached network.
Ping -RPing -RRecord Route. Turns on route recording for the
Echo Request
packets, and display the route
buffer on returned packets (ignored by many
routers).
ping -s PacketSizeping -s 10Sets 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 -vping -vVerbose 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...:-)

3.     Thanks http://thehackernews.com

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






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 "

3. Brief of this good news goes like this in a Short ppt

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

Upgrading Fedora 17 to Fedora 18

1.   Like me so many of you would have been waiting for the final release of Fedora 18 spherical cow...but at the same time when u see it released u have so many links to move around on how to upgrade from 17 to 18 but u keep ending up with previous one....i went through the same for past hour...:-)

2.  The only set of commands Fedora 17(only) users need to put in are these :
Reach the Root first with the password ie 


su -
*******(ur password)
su -c 'rpm --import https://fedoraproject.org/static/DE7F38BD.txt'


su -c 'setenforce Permissive'

su -c 'yum update yum'

su -c 'yum clean all'

su -c 'yum --releasever=18 --disableplugin=presto distro-sync'

su -c 'rpm --rebuilddb', or rpm -qa will not work due to a upgrade of rpm

3.   For me the upgrade is around 1.6 G as seen in the screen shot below :


4.   Mine is upgrading on way....another few hours should be ok....:-) all the best for your upgrade

Apple Needs a Doctor : Bitten by JAVA - 2

1.    The Flashback fiasco,as discussed in brief here, was the catalyst for one of the most meaningful decisions Apple made in order to beef up OS X security ie Removing JAVA. "Flashback both led to Apple removing Java from their default installs, and prompted them to release a dedicated cleanup tool," security researcher (and former security engineer for Obama for America) Ben Hagen told Ars. "When an OS vendor releases a dedicated cleanup tool, you know things are bad.The removal of Java was a very Interesting decision and de facto statement by Apple. Java on user systems has become a notorious vector for exploitation; with new, remotely executable vulnerabilities coming out several times last year," Hagen said. "Removing Java both simplifies Apple’s position and provides a safer default state for its users."[Source : http://arstechnica.com/].

2.    Another key decision taken by apple apart from disowning JAVA was endevor to signed security model for apps ie restrict the origin of third-party apps installed on the system, therefore protecting the user from inadvertently installing apps from malicious or unknown sources.Called Gatekeeper, this feature required Apple's developer ecosystem to either sign their apps with a registered certificate—holding them at a higher level of responsibility for when things go haywire—or selling their wares through the Mac App Store and giving Apple its 30 percent cut. [Source : http://arstechnica.com/].

3.   Java is a veri popular program and is used by millions of users worldwide in Windows, Mac and Linux operating systems and in mobile and television devices. It is this popularity that has made it a favorite target of the hackers.So today when we cannot surf without enabling JAVA.....apples decision is indeed a tough step....for those of you who do not realise the importance of JAVA...just try surfing the web disabling JAVA scripts in your browser...u will be surprised you will be prompted at every step to ensure a successful loading of most of the web pages....In fact the U.S. Department of Homeland Security advised computer users to temporarily disable or uninstall Oracle Corp's Java software, stating that a serious flaw in the software could make the system vulnerable to hacking.The warning came in an advisory posted on the department’s website amid the escalating fears and warnings from the net security experts about a flaw in Java Runtime Environment (JRE) 7 and earlier versions that allows the hackers to install malicious software and malware on computers.The vulnerability is so dangerous that the Department of Homeland Security's Computer Emergency Readiness Team urged the people to stop using the software immediately to mitigate damage.Source : [http://www.ibtimes.com/]

4.   So...did u just start thinking of disabling JAVA?????

Apple Needs a Doctor : Bitten by JAVA - 1


1.   The year last ie 2012 was full of various security OS issue like it has always been over years...but one landmark news that made waves was the flashback malware that hit APPLE's Mac that has been long promoted as a safer OS amongst other peer competitors.But as always SIZE DOES MATTER..so as APPLE and market share grew, it became more proner. Dr  Web said that an estimated 600,000 Macs were as of April 2012 infected as a result of users unknowingly installing the FlashBack malware.So before I move ahead...here's a simple FAQ compiled to understand more about FLASHBACK :

What exactly is Flashback?

-  Flashback is a form of malware designed to grab passwords and other information from users 
-  Spread through Web browser and other applications such as Skype. 
-  The user typically mistakes it for a legitimate browser plug-in while visiting a malicious Web site. 
-  At this point, the software installs code designed to gather personal information and send it back to remote servers. 

Apple needs a DOCTOR


When did it first appear?

-  End of September 2011
-  Pretending to be an installer for Adobe's Flash the malware evolved to target the Java runtime on OS X, where users visiting malicious sites would then be prompted to install it on their machine in order to view Web content. 

What has Apple done about it?

-  Apple has its own malware scanner built into OS X called XProtect. 
-  Since Flashback's launch, the security tool has been updated twice.
-  A more recent version of the malware, however, got around XProtect by executing its files through Java. 
-  Apple closed off the malware's main entry point with a Java update on April 3, and has since released a removal tool as part of a subsequent Java update.

How do I tell if I have it?

-  Right now the easiest way to tell if your computer has been infected is to head to security firm F-Secure and download its Flashback detection and removal software.

1.     Internet today is all but a minefield of boogies,traps and malware.....every day so many threats are born....though most of them die but still a huge percent of them survive the security walls and become stronger by time as they are able to remain live and acvtive.In recent times shortened URLs have become popular amongst users (including me...:-) to conserve the typing space like in microblogging sites viz twitter etc.So typically a naive(???),prone user who submits his long URL to a site to get a shortened URL receives a second,specially coded shortened URL that redirects to the original URL.So here lies the weak hole that is most of the times exploitable by the attacker...because the actual destination URL is hidden in it....so going by the looks...there is nothing to worry...but it is the redirection that is a cause of worry...it may be right or may be redirecting to a malicious link....!!!!so when some one uses a free URL shortener ,he does not have control over that shortened link. And, should something happen to the provider of that URL shortener, then he risks redirecting ALL of shortened links elsewhere!!!

2.  We all know that clicking links is pretty tempting....so it is just a matter of one redirected malicious link click that makes the difference....so whats the solution????...actually companies like Facebook,Gmail, SBI, Paypal ,twitter etc are offering users the option of persistent SSL encryption and authentication across all the pages of their services including the login and all accessible pages.....but this does not stand good for all...for these sites also..it is optional to vide the settings for accessing....

India developing own Secure OS to strengthen Cyber Security


1.   India is developing own secure OS to strengthen cyber security.Got this news piece from here.The key points from the news are :

- India's own secure operating system to strengthen cyber security.

- 150 Engineers across the country have already been working on creating an Indian OS for over one year and a half. 

- According to Times of India ,it will be ready in next three years.

- There is no foreign involvement in this project. It is purely build by Indians.

2.   It is indeed heartening to know all this...but whats the point? Does the team of 150 engineers and the vision behind think they are creating a secure and 100% fool proof OS?...The moment it is released...there will be many vulnerabilities that will be gradually known...and then the same cat mouse race will being like with any other OS..so whats the point of starting from scratch?....will it not be wise to securify existing opensource available and invest in something like improving upon existing resources?.....Case in point,the DESI OS....will lag behind in terms of experiences gained by Windows and other OS Communities who have been in the game for years...........who have been improving daily for so many years!!!like Fedora...Ubuntu...they have been improving for last so many years to reach a level like as on date available to us....

3.  Although it is a veri good thought to have a desi OS....but I sincerely feel that we are slightly late in realizing the need of a desi OS...

MALWARE via SUDOKU via EXCEL SHEET


1.  Sudoku is good for you brain....but it may compromise your PC if you have downloaded one of the excel files with embedded malicious script inside that offers you to play the subject game. Peter Szabo from SophosLabs has identified a piece of malware that resides behind a Microsoft Excel-based Sudoku generator. The Malware developed in Visual Basic requires macros, a scripting language that allows users to create equations based on values in different columns and rows. Microsoft – Malware behind Microsoft Excel-based Sudoku generator.

2.   Although by default the macros are disabled in any Microsoft Office application....but any one who downloads the excel file would eventually enable the macros that run the script to play the game...so he can keep playing the game while the script in the background sets up the malware and establishes contact with its master bot.....so like always the updated Antivirus on the system will keep sitting without catching up anything.....so comes the importance of packet analyzers like Wireshark....ethreal etc...but then it becomes slight technical which in most cases would be out of purview for a common user.

MSE : Loosing Shine

1.   Since last few years any one who asked me on recommending a Antivirus for his/her PC...I would always say if you have a original Windows...then leave your worries to MSE...thats Microsoft Security Essentials ie MS's own antivirus or may be I would recommend Kaspersky PURE in few other cases who were not happy with MSE.

2.  I had been using MSE for my own system as well...and I found it worked pretty fine...light on use and had no major compatibility and configuring issues since it worked mostly in the background.But there has been some decline in recent time and efforts by Microsoft in keeping with the pace of the hackers and cyber criminals!!!

3. The AV-TEST Institute,the leading international and independent service provider in the fields of IT security and anti-virus research.It uses state-of-the-art methods and research work to carry out AV-TESTs to  directly detect the latest malware, to analyse it  and to inform web site visitors top-quality results obtained.So the latest results showed MSE being given 1.5 out of 5 maximum ratings.The screen shot from the link http://www.av-test.org/en/tests/home-user/windows-7/sepoct-2012/ is shown below :

4.   And to me, that's a huge concern considering how Windows 8 itself draws on a lot of MSE for its own in-built security....:-)

Need of Encryption : Your files - Your Data


1.   In today's times when every spying eye,every hacker on the web is eyeing your info.... apart from hardening your OS and configuring your system securely what else can you do to secure your info after some one gate crashes into your system?.....I mean after someone gets your root privileges via remote access...what are the options to save your self from sharing your critical data with him?The answer is ENCRYPTION...

2.   Encryption is the process of encoding your information) in such a way that hackers cannot read it, but that authorized parties can.So without getting into the nitty gritties of what is Encryption and how it works..i am focusing here of what all opensource and free applications are available for encryption...

3.   First I would mention about TrueCrypt,this is the one I have been using for years...the reliability of this application can be gauged from the fact that in 2008, the FBI attempted to break encryption on hard drives using a program called TrueCrypt, but the equipment was finally returned after a year of failed tries.(Source : http://www.webcitation.org/query?url=g1.globo.com/English/noticia/2010/06/not-even-fbi-can-de-crypt-files-daniel-dantas.html)

4.   The other strong opensource software's available for encryption are :

    - E4M ie ENCRYPTION for MASSES)
    - Free OTFE
    - Scramdisk

5.   TrueCrypt remains the best bet for all present users.The popularity can be gauged from another fact that this is being used by cyber criminals to!!

TrueCaller : Is it Stealing your Info?

1.    TrueCaller is one famous application doing the rounds on Twitter Google+ Facebook Android Phones.The claim by the application goes like you login from either of the applications and you would be able to know the name of the mobile phone number owner by name.The claim actually stands right in over 90 % of the cases that I tried.This made me wonder how?...i thought like all those free forms that we keep regularly filling on the internet or some grocery shop for some free bundles or if TrueCaller has tied up with the mobile phone service providers?But then something happened that made me a little suspicious about this app.It so happened that I tried my mom's number on the application and so came the answer like "TIWARI MAM"....this made me think of how would the application know that my mom is a teacher...

2.   So I wondered if the application after installation on your mobile device actually makes all the contacts phone number available on the site with the name that I have typed against that number!!!So I tried mine which was not available, by the name "anupam CCCSP"



3.  Though it did not show promptly but after a day after I typed my phone number it came to be seen as "anupam CCCSP".So this actually means that the application is actually stealing and making my contacts info on my phone public!!!!...but then I also realized that it was me only who agreed to the terms and conditions while installing the app on my phone which most of us including me never read.

4.   So it comes actually to the naiveness of the common user who invariably without reading any of the terms and conditions agrees to install.....:-)
