Reliance Jio is still not at the point of a commercial rollout, so it's too early to say what the actual user experience will be like on the network. Even the actual pricing has to be announced - as of now, not much is clear really about the network. But you can sign up for Jio and enjoy high-speed connectivity without paying a paisa, and free hai to acha hai, right? That's right, each Reliance Jio SIM comes with at least three months of free, unlimited data usage, voice calls, SMS, and access to Jio services like JioOnDemand.

The commercial rollout of Jio will no doubt affect speeds, network availability, and could lead to call drops as well - while other networks, which stand to lose customers in the process, might actually see some improvement in their services. That's all hypothetical though - but for now, we are really enjoying using our Jio account, and would recommend that you try and get one too.

There are a few different ways in which you can get a Reliance Jio SIM. The network works on 4G, and uses VoLTE for calls, but the latter is not available on old phones. There is an app called JioJoin that Reliance offers which works around this through VoIP calling, in case your phone doesn't support VoLTE, so it isn't a very big problem. The easiest way to get your hands a Reliance Jio SIM is to buy a Lyf phone by Reliance Retail.

Reliance Retail's Lyf range of phones hasn't been getting the most spectacular reviews, but it's the easiest way to get a new Reliance Jio SIM right now. Just walk into a Reliance Digital Store, ask for a new Lyf phone, and you're live on Reliance Jio. You can get a phone for as little as Rs. 3,000, and you'll get three months of free, unlimited Internet access and calling along with it.

We can inform you that buying a phone like this, turning on the Wi-Fi hotspot, and using 4G to power your entire home's Internet access, works just fine, and the speed and reliability (at the moment) is better than most broadband connections at home.

This gives you free, unlimited data, calling, and access to all of Reliance Jio's apps for three months, or until the commercial launch of Reliance Jio, whichever is later. But if you don't want to carry around an extra handset everywhere you go, or don't want to buy another phone just to get a Reliance Jio SIM there are other options.

If you have a 4G compatible phone, you can get started with Jio, here's what you need to do to get a Reliance Jio SIM:

1) Make friends with someone working for Reliance
The easiest way to get a Jio SIM is to know someone who works with Reliance. The company allows employees to refer a certain number of people to get Jio SIMs that can be used in your phone. Most Reliance employees are probably used to getting friend requests on Facebook from people that just want a SIM, so you might want to try one of the other methods instead.

2) The Reliance Jio SIM Preview offer
The partner offer is the easiest way of getting a Reliance Jio SIM if you have any of the eligible phones. As of writing this report, the Jio Preview offer has been extended to smartphones by Samsung, HTC, Micromax, Sony, Vivo, Intex, Lava, Gionee, Panasonic, Asus, Xolo, LG, Karbonn, Videocon, YU, Sansui, Alcatel, and TCL.

Just follow these steps on a qualifying smartphone:

1. Download & Open MyJio App from Play Store
2. Tap on Get Jio SIM on the Banner
3. Tap on Agree & Get Jio offer
4. Select your location from the drop down
5. Read through the steps and click on Next
6. Offer Code can be viewed on the screen. Note down your offer code.

Once that's done, you will get a bar code that you need to take to a Reliance Digital where you have to show your phone and you'll get a SIM. Remember to carry a photograph for the form, and your photo ID, and the staff will do the rest. Quick tip: in our experience - and what many other people online are also telling us - the Reliance Digital Xpress Mini Stores are much more efficient about this process than the larger Reliance Digital stores.

Note that though only a few phones qualify for the Reliance Jio SIM under this offer, you can still use this SIM on other phones if you want.

3) Get a JioFi Portable Wi-Fi hotspot
Jio is also keen to go after users at home, taking on broadband providers and not just other phone networks. One of the easiest ways to get a Reliance Jio SIM is to get the JioFi router. Launched first for HP customers, anyone can now get the JioFi router, with three months of free 4G data, although you have to pay Rs. 2,899 for the wireless compact router. That still works out to less than Rs. 1,000 a month for free, unlimited, fast data, so it's a pretty good deal considering that unfair FUPs are the normon all other networks.

The JioFi is a small Mi-Fi device that can create a Wi-Fi zone that up to 31 devices can connect to SIMultaneously; great for taking your phone, laptop, and tablet online all at once. It takes three hours to charge, and can be used to broadcast a signal for six hours on battery, so you can use it at home or on the go. To buy the router, you just need to get it from a Reliance Digital store. You'll need the same documents you need for a SIM card, and you'll have to televerify in the same manner, but then you're up and running.

4) Ask nicely at your local Reliance Digital
Owners of any 4G smartphone can walk in to select Reliance Digital and Xpress Mini stores and get their hands on a Reliance Jio SIM, complete with the Jio Preview offer. The catch is that the offer is only available in select outlets, which can offer Jio SIM cards to customers at their discretion. You can try asking nicely at your local outlet... and if that doesn't work, try at a few other stores as well until someone feels bad and gives you the SIM.

All these methods can help you get a Jio connection right away, before the actual consumer launch in the "coming months". Have you got a Reliance Jio SIM? What's your experience been like? Tell us via the comments.

Functioning of a Web Server

Internet has become a part and parcel of our daily lives. Surfing the net is facilitated by complex mechanisms at the room of which lies the entering of web address of the desired site. Entering domain name in the URL ( Universal Resource Locator) will cause the URL to be separated in three parts, namely the protocol , server name and the field name . Suppose , we have chosen the URL http://www.ebay.in/web-server.htm; here http is the protocol , www.ebay.in is the name of the server , and web-server.htm is the file name.

The chosen browser (Internet Explorer, Firefox ,Chrome etc.) communication with the name of server for translating the entered server name ‘www.ebay.in into an IP address. This ip address is used for connecting the server in which information of the chosen site is stored. Port 80 is used as bridge for allowing the browser to establish a connection to the server at the generated IP address.

The http protocol acts as a cynosure following which the browser transmits a ‘get’ request to the desired server, demanding information pertaining to the file http://www.ebay.in/web-server.htm. In response to this , the server transmits the HTML text for the desired web page to the browser. The browser is capable of deciphering the HTML tags and formats the page intuitively to suit your computer’s screen.

Loopholes of Web Server /Web Application

The web server is vulnerable to a host of potential attack modes which tend to compromise the performance and security. The loopholes in the web server can be exposed and exploited by

• Injection Attacks
• PHP Remote File Includes
• Cross Site Scripting (XSS)
• Cross Site Request Forgeries (CSRF)
• Insecure Communications

Some web server that rank higher on the popularity scale are:

• Apache Server
• Microsoft IIS Server
• IBM Lotus
• Lighttpd

Vulnerability of the Apache Server

• CVE-2013-2249 – mod_session_dbd.c in the mod_session_dbd module in the apache HTTP Server before 2.4.5 moves forward with save operations for a given session without factoring in the dirty flag and the need for a new session ID , which is rife with unspecified actions and remote attack vectors.
• CVE-2013-1896 – mod_dav.c in the Apache HTTP Server before 2.2.25 fails to ascertain properly the enabled status of the DAV for a given URL. This Facilitates launching of a  denial of service (segmentation fault ) assault by remote attackers through a ‘Merge’ request. IN this request , the URI has been setup to be handled by the mod_dav-svn module, however a given href attribute points to a non-DAV URI.
• CVE-2013-1862 – mod_rewrite.c in the mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 . Here the data’s written in a log file without the sensitization of the non printable characters. This leaves scope for execution of arbitrary commands by the remote attackers through an HTTP request that contains an escape sequence for a terminal emulator.
• CVE-2012-4558 – Multiple cross site scripting (XSS) vulnerabilities in the balancer_handler function in the manage interface in mod_proxy_balancer.c in the mod_proxy_balancer  module in the Apache HTTP Server 2.2.x before 2.4.x .This permits injection of arbitrary web  script of HTML by remote attackers through a crafted string.
• CVE-2012-4557 – The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 . It puts in a worker node into a error condition when it detects a log request processing time. this facilities causing of a denial service (worker consumption ) by remote attackers through an expensive request.
• CVE-2012-3502 : The proxy functionality in (1) mod_proxy_ajp.c in the mod_proxy_ajp module and (2) mod_proxy_http.c in the mod_proxy_http module in the Apache HTTP Server 2.4.x before 2.4.3 . Proper assessment of the situation that demands for closing a back end connection is not done. This makes it easy for remote attackers to gain access to critical information in opportunistic situation by deciphering a response , which was meant for a different client.

Ways to Launch Assault against IIS Server

• Path Traversal
• Known Worms
• Remote Command Execution
• Probes
• Denial of Service Attacks
• Compromised Servers

IIS Server Components

Efficient configuration of an IIS server requires proper understanding of the critical IIS components at first. The IIS server components have a wide range, but the prominent IIS components have been enumerated below for ready reference.

1. HTTP protocol stack (http.sys)
2. WorkerProcess
3. WWW Service Administration and Monitoring
4. HTTP Protocol Stack (HTTP.sys) – During the creation and hosting new website, IIS carry out the registration of the site through http.sys . IT responds to the entire array of hyper text transfer protocols for the website.
5. http.sys is a driver used by IIS. In IIS , fast processing of requests and non-interruption of service in the event  of the failure of a worker process is ensured . The following services in IIS 6.0 are provided by Http protocol stack:
6. Routing HTTP services to the proper request queue.
7. Caching of requests in kernel mode and the last one is carrying out text based logging for WWW service.
8. Worker processes – The requests such as returning a static page or running a CGI handler are processed. The IIS can be configured for running multiple worker processes.
9. WWW Service Administration and Monitoring – Like http.sys and worker process this component is built in with core IIS functionality that never loads external code. it is responsible for the management of the worker processed . It includes starting the worker process and maintaining the information about running worker process

IIS Director Traversal

Microsoft Internet Information Server (IIS) offers to ability to a remote to gain insights of the directory listing on the Web server . This is due to loophole in Web Distributed Authoring and Versioning (WebDAV) search function. This vulnerability can be exploited by a remote attacker to search for and view certain files on the system such as .inc files which may carry critical authentication information pertaining to usernames and passwords .

These issues can be resolved by employing the below mentioned efforts:

The ” index this resource ” option should be necessarily disable for directories containing critical information.

In the event that the index server is not required in active use, the same should be disabled or uninstalled

Unicode and Unicode Directory Traversal Vulnerability

The Unicode vulnerability of the IIS server has been exploited by Red Worm, and Red Worm II, and Nimda worm for achieving their ulterior objectives. There are two major vulnerabilities . The first vulnerability pertains to is IIS/PWS Extended Unicode Directory Traversal Vulnerability whereas the second vulnerability is related to IIS/PWS Escaped Character Decoding Command Execution Vulnerability .

Hacking Tool:

There are some hacking tools available on the web , which may be exploited by even inexperienced hackers to break into the security of IIS servers. The most important of the are listed below.

IISxploit.exe

                                    IISxploit

execiis-win32.exe: Another hacking tool which exploits the IIS directory traversal and accepts command from a cmd prompt for execution of the exploit on the IIS server.

                         execiis-win32

RPC DCOM Vulnerability

The RPC DCOM vulnerability is present in the windows component object model subsystem , which is a critical service put in active use by a majority of windows applications . it has been detected in 2003s july . The DCOM service is activated by default in Windows NT , 2000, XP , and 2003 . The RPC protocol makes way for a program to execute run code on a remote machine . This allows the attackers to search for the vulnerability in COM via any of the given ports:

Port 135 – Remote Procedure Call

Port 139 – NetBios session service runs on this port and all the file and printer sharing on a windows machine runs over this port

Port 445 – TCP port 445 is used for direct TCP/IP MS Networking access without requiring the intervention of a NetBIOS layer.

Port 593 – HTTP RPC Ep Map , Distributed Component Object Model and Microsoft Exchange Server services.

Hot Fixes and Patches

Hot fix refers to a code, which is used for fixing a bug in the product. Users of the product will come to know about hot fixes through notification published on the vendor’s website. Product clients can come to know about the same also through emails from the vendor. Hotfixes sometimes come packaged as asset of fixes known as combined hot fix or service pack. A patch can be viewed as a repair job done to attend a programming problem which attempts to provide an alternate code which is thoroughly rid of the known vulnerability of previous code.

Countermeasures of Web Server

• One should use well configured and acclaimed firewalls only for heightened security
• The administrator account should be renamed in a manner it is not easily predictable
• If any unused application if floating around , the same should be removed
• Disable directory browsing
• Service Packs, Hot Fixes , and Templates
• Analysis of Malicious input in forms and Query Strings so that the attacker cannot exploit the inherent vulnerabilities of that
• Disabling of Remote Administration

By adhering to the aforementioned steps , you can minimize the risk of external malicious attacks on the IIS server by hackers.

How To Hack WhatsApp Using SS7 Flaw

 

Researchers are easily able to hack WhatsApp and Telegram using the known telecom flaw.

We continuously receive queries from readers about how to hack WhatsApp. The world’s most popular cross platform messaging App is seen to be ultimate hack by many because it has recently enabled 256-bit encryption.


For ordinary souls this encryption would take days and months to decode a sentence or a complete message. Ditto with another secure messaging service called Telegram. Though Telegram is not as popular as WhatsApp, it has its ardent group of followers who use it for its encryption as well as snooping free service.
Though both of these Apps are end-to-end encrypted both of them suffer from hardware side vulnerability which can be exploited to hack and hijack both WhatsApp and Telegram.

The vulnerability lies in Signalling System 7, or SS7, the technology used by telecom operators, on which the highly secure messaging system and telephone calls rely. SS7 is a set of telephony signalling protocols developed in 1975, which is used to set up and tear down most of the world’s public switched telephone network (PSTN) telephone calls. It  also performs number translation, local number portability, prepaid billing, Short Message Service (SMS), and other mass market services.


SS7 is vulnerable to hacking and this has been known since 2008. In 2014, the media reported a protocol vulnerability of SS7 by which both government agencies and non-state actors can track the movements of cell phone users from virtually anywhere in the world with a success rate of approximately 70%. In addition, eavesdropping is possible by using the protocol to forward calls and also facilitate decryption by requesting that each caller’s carrier release a temporary encryption key to unlock the communication after it has been recorded. Researchers created a tool (SnoopSnitch) which can warn when certain SS7 attacks occur against a phone and detect IMSI-catchers.
