Single-Pixel Detectors – Future of 3D Imaging

Posted by & filed under Research, Social, Web.

Researchers from University of Glasgow’s finds a new way for capturing 3D image of objects in much more affordable technology, they use a  technique called ghost imaging or 3D Computational imaging to process the captured images. Single Pixel detectors use only Single Pixel rather than millions of pixels used in digital camera detectors.

They are using four single-pixel detectors to capture the image from data projector in the form of shadows, Using “shape from shade” technique images from four detectors are merged to form a 3D image and these detectors are capable of capturing wavelength from far beyond the current digital cameras from x-ray to Terahertz. Planning about the commercial version of this product is ongoing   because of its wide usability in geography and medical areas.

Anna University Website Compromised By Hackers!

Posted by & filed under Security.

It looks like Anna University official website (http://annauniv.edu/) was compromised by hackers and now acts as a carrier for malicious malware planted by them. “Google Safe Browsing” marked Anna University webpage as harmful to the viewers’ computer and recommends them to stay away from the site. Even Google search gives a warning reading “This site may harm your computer” as shown in the below image.

anna university hacked

Google identifies a site as harmful when they find any malicious software (malware) being downloaded and installed from that site to the user computer without user knowledge. Malicious scripts, .htaccess redirects and hidden frames which are commonly found on websites that were compromised by hackers are also the factors that help Google to decide if a site is harmful. Here chances are that the annauniv.edu might have been compromised through a security hole, like outdated software or plugins, stolen passwords, or insecure permissions. Even using an infected PC to update the website could have caused the site to become infected.

According to Google safe browsing, there is an exploit (malware) found on the website over the past 90 days (until January 11, 2013) in around five webpage and the infection was spread even into annauniv.ac.in. It is unfortunate for Anna University webmasters as they need to take the site offline for a while to locate and remove the malware or even they might be needed to clear the entire infected server and re-upload the site entirely to ensure the safety of the viewers and their own server.

U.K Ministry Of Defence Website Hacked: The Whole Database From MOD Server Was Leaked

Posted by & filed under Security.

MOD hackedNullCrew, a hacking group allegedly entered into the servers and leaked the entire database belonging to the U.K Ministry of Defence (MOD). The hackers claimed that they made use of the SQL injection vulnerability existing in the MOD website to get into the servers, which exposed the poor security measurements maintained by MOD.

The dumped database contains mostly the login credentials including username or email and password, which I believe would have urged the webmasters of the MOD website to reset the passwords for every users (including their own). The hackers also left a message along with the dumped data to MOD as,

Message: Your webmaster made a terrible mistake… You may criticize us on the simplicity of the vulnerability. But if you can get so much useful data so easily, why wouldn’t you? We hope that all governments and organizations realize that #FuckTheSystem is definitely not a joke. We hope that you have the decency to grasp the concept of it. But hey… You’re the government right… Just some butthurt little fags. This security just proves how much of a joke our governments are.

The whole dumped database is available at Par:AnoIA, the Potentially Alarming Research: Anonymous Intelligence Agency website and also (as usual) in Pastebin.

342,478 Email Addresses and Passwords Hacked And Leaked From Yahoo Voices

Posted by & filed under Security.

Yahoo-sad-faceEvery major tech blog confirmed a huge security breach in Yahoo Voices lately that, 442773 of which 34,2478 unique email addresses and passwords of various domains including Gmail.com, Yahoo.com, AOL.com, Hotmail.com, MSN.com and from others were leaked. It must be embarrassing to a high-profile tech company like Yahoo which confirmed the leaked email and passwords were of course in plain text format.

According to The NY Times and other major tech blogs D33D company was responsible for this huge dump of data; even the hackers warned Yahoo that this leak was just to point out the security holes existing in their servers, and there were several vulnerabilities exists in some Yahoo sub-domains unrevealed. The infamous SQL injection (union-based) was used by hackers to infiltrate into the victims database while Yahoo was still unclear whether the hackers got out of the servers completely or not. That means, clearly Yahoo is in a big trouble and needs some time to regain their servers with full security and clear this mess created by data leak.

Out of 442773 email addresses and their respective passwords, only 137556 email addresses were from Yahoo.com while 106869 accounts from Gmail.com, 55147 hotmail.com, 25520 aol.com and so on goes the list. In this mayhem, there was a good news too, that there were only 1666 accounts have 123456 as password. Compared to the data obtained from the previous hacks and leaks, this number was very far less than usual and so do their was a fall in usage of other feeble passwords like password, qwerty, monkey, jesus, love and welcome.

Right now, all you could do is check whether your email address was hacked or not at Sucuri Malware Labs and change your password immediately if it was. Although this leak has nothing to do with the password strength, I highly recommend setting up a strong password.

 

How To Play “.wma” Format Audio Files In Android Smartphones

Posted by & filed under Android, How-To, Smartphone.

Not every Android powered smart phone default music player can play wma format audio files. Although some Smartphones powered by the versions of Android less than 3.0 supports wma files, but as far as I know most of the Android phones powered by Android 3.0 and above doesn’t play wma files on default music player and so do my phone. So obviously I started digging into Google play to find a music player that can play me wma files, possibly for free. I found a bunch of music players for Android, and yes I installed them all and none of them played wma file type.

PowerAmp player that supports wma files on AndroidFinally, I found Poweramp player which actually costs $5 and I’m glad they provide a trial period of 15 days to try the player out. Actually I did tried the Poweramp player and it was quite good to use and may be even cool, I say. But I wasn’t convinced on spending $5 over a music player and so didn’t I.

I converted all the wma files into mp3 files using a free file conversion software (FormatFactory) and then used the same old grumpy default Android music player to play them all. But Poweramp player sure worth $5 dollars, if you want to save you both time and resource by skipping the conversion process every time you come across some wma files. Check this Poweramp app page on Google play for reviews and download.
Note: I also found some other players like Astro and PlayerPro says that they too support wma files, but those players would play wma files on devices that already supports wma files. So correct me if I am wrong that, “there is a single music player that supports wma files on all  Android powered devices and that player is PowerAmp”.

How To Use Internet Anonymously And Unblock Censored Websites In Android Smartphones

Posted by & filed under Security.

It is always important for some people to protect and preserve their online identity and most importantly the IP address of the device they are using. In this Smartphone age, every one is getting used to browse through internet from mobile phones and to keep tract of their social networks. But mostly they forgets that, even their mobile devices acquires an IP address similar to their computers and this mobile IP can help others to easily track them down from their real name to location.

I actually use Android based Smartphone, so here I’m going to crack down two methods that I use “to keep my online identity safe” or “to hide my IP” and also to unblock the censored websites.

1. Proxy

2. Tor for Android

Proxy:

Proxy is always the easiest way to protect your online identity or to hide your IP without any pain or spending money (mostly). In general proxy IP’s are IP addresses that could be used as a mask to hide your very own IP address that is allocated to your computer by an ISP (Internet Service Provider).

Here is the simple steps to use proxy.

1. First of all, we need proxy IP’s that we are going to use to hide our IP address. I prefer proxy IP’s from Samair.ru and hidemyass.com/proxy-list websites to get the proxy IP’s while a number of other sites like http://anon-proxies.com/, http://www.freeproxies.org, http://www.socks24.org, http://www.samair.ru/proxy, http://www.newipnow.com/, http://www.proxy-list.org/en,  http://www.hidemyass.com/proxy-list/,  http://www.checkedproxies.com/,  http://www.multiproxy.org/,  http://www.xroxy.com/,  http://www.proxy.org/ are also available. If you are about to go for hidemyass then you could search for high-speed, highly anonymous proxy IP with the port number of your choice and even you could get the IP address of the country you want and then note/copy the IP address and the respective port number of that IP.

2. Go to settings in your Android mobile and in settings tap over the “Wi-Fi Setting”.

3. At the bottom, in the Wi-Fi settings there will be proxy options from which, first tap over “enable proxy” if it is not already enabled.

4. After enabling proxy, tap over the “proxy settings” that lies next to the “enable proxy” option. Now, it will ask you to enter the IP address and port number, which you already obtained from either Checked Proxies or Hide My Ass.

5. After filling up the IP and port number, to check whether your proxy works fine, go to your browser and visit the site “whatismyip.com”. If you configured the proxy correctly, the “whatismyip.com” will show you the IP that you filled on “proxy settings”.

Pros:

1. Easy to change the IP anytime and costs nothing.

Cons:

1. Proxy IP’s are mostly unstable, I mean the proxy IP’s could become slow or unmask your IP anytime.

2. It is not safe to use your personal accounts and make transactions over proxy. They are prone to hackers and could easily get your accounts hacked. So, stay away from proxies if you are about to do money transfer or transactions, unless you have a premium proxy service or VPN.

Tor for Android:

Orbot is the Tor for Android developed by the developers from Tor project to help Android users to keep themselves safe from online surveillance and identity theft. Although Orbot is not as good as Tor for desktop which is an out of the box browser that could be used just by extracting the downloaded Tor package.

In the device I tested Orbot which is powered by Android 2.3.6 but not rooted, so instead of asking me for Android Super User access that Orbot asks on rooted devices it asked me to download two other Orbot-Enabled apps Orweb and Gibberbot during the installation process. If you are having a rooted Android device, then Orbot will ask you to select which apps to use through Tor as an Android super user and in next few clicks you will finish the installation process. The other users with non-rooted device just follow the few simple steps below to start using Tor on your Android.

Tor successfully connected on Android - Orbot Orweb, is nothing but a privacy-enhanced browser which was compatible and could work through Tor and so do the Gibberbot except it is a secure chat app with off-the-record encryption. You could download and install them by tapping over the download link suggested by Orbot which will eventually lead you to Google Play or you could just install them later directly from Play.

After installing the above two apps and Orbot, now open the Orbot app from your device, click and hold on the screen where it says “Tor deactivated” to let the app automatically activate and connect you to the Tor network. Once the app connects your device to Tor network you are ready to go and open the Orweb browser that automatically checks and tells you whether you are successfully connected to Tor or not, so that you can continue browsing on Android through Tor network.

Pros:

High level of anonymity con be obtained through Tor and in addition Tor could unblock every single censored websites based on your location and the IP address given to you by Tor.

Cons:

1. It is not safe to do online transactions or shopping and other similar activities. So never ever try the aforementioned activities until the Tor developers team says it’s “safe now”.

2. Don’t use Tor while you are downloading any files via Torrent on both desktop and Android smartphones, as they might reveal your IP address.
