Voice-over-Internet Protocol (VoIP)

Voice over IP
Voice-over-Internet Protocol (VoIP) is a
methodology and group of technologies for
the delivery of voice communications and
multimedia sessions over Internet Protocol
(IP) networks, such as the Internet. Other
terms commonly associated with VoIP are IP
telephony, Internet telephony, voice over
broadband (VoBB), broadband telephony, IP
communications, and broadband phone
service.
The term Internet telephony specifically
refers to the provisioning of communications
services (voice, fax, SMS, voice-messaging)
over the public Internet, rather than via the
public switched telephone network (PSTN).
The steps and principles involved in
originating VoIP telephone calls are similar
to traditional digital telephony and involve
signaling, channel setup, digitization of the
analog voice signals, and encoding. Instead
of being transmitted over a circuit-switched
network, however, the digital information is
packetized, and transmission occurs as IP
packets over a packet-switched network.
Such transmission entails careful
considerations about resource management
different from time-division multiplexing
(TDM) networks.ternet Protocol (VoIP) is a

Target website hacking

>firstly you can use the scanner like
acuenetix,netsparker,nikto,nessus etc
and you can check the known vuln like the
sqli,rfi,lfi,web dav etc
>if this attack can not success then you can
use this awesome trick
-firstly by using http://www.yougetsignal
.com/ that website you can find the all
website which is running on that server
- after that you can by using bing search
engine
-and check target website is on shared ip
-on the bing search ip:server ip adress
-ip:server ip adress .php?id= (for checking
sqli vuln website on that server)
-ip:server ip adress admin (for checking the
admin of that website in that server and use
sql injection)
-ip:server ip adress upload (for upload the
shell on website)
>if you get any vuln(like -sqli,rfi,web dav etc)
you can upload your shell on that website by
using that shell you can get access on the
target website.once you get access on target
website you can deface the whole website
******************************
**********************************
there are several dork for finding vuln
you can create your own dork and use that
for hacking all the website on that server

Eight unknown facts of android -

• It wasn't Google's idea: Android was the
brainchild of
Andy Rubin, who founded Android Inc. in
October 2003
with the aim of creating a new mobile
platform. Google
later bought Android Inc. and hired Rubin
and others in
August 2005.
• It almost didn't work out: Android almost
immediately
ran out of cash after its founding, only to be
saved,
according to the Businessweek, by Steve
Perlman.
• The Nexus line was a hot rumour years
before the
Nexus One: People started predicting about
the
"gPhone" as early as 2007 though Nexus
came out in
2010.
• Microsoft thought it would be a non-event:
Microsoft's Scott Horn, then head of the
Windows
Mobile marketing team, had told Engadget
after
Android's release, "I don't understand the
impact they
are going to have."
• Resolution scaling was introduced in
Version 1.6: The
ability to automatically scale images based
on display
size appeared in Donut, or Android 1.6,
paving the way
for the huge range of device form factors on
the Android
market today.
• There's an Android phone in space: A
British firm
launched a Nexus phone on Space, to control
a satellite
as part of an experiment and see how well
consumer-
grade electronics stand up to the rigors of
space.
• Every app you run on your Android phone
gets its own
virtual machine: Each active app on an
Android device
runs in its own Dalvik VM, which keeps it
safe and
separate from core functions. This improves
battery life
and boosts performance of the phone.
• The first official version code name was
NOT a
dessert: Google's Dan Morrill confirmed in
January that
the very first alpha version of Android
released to
internal developers was R2-D2.

Why Programming For Hacking ???

Learn a programming language. You
shouldn't limit yourself to any particular
language, but there are a few guidelines.
C is the language the Unix was built with. It
(along with assembly language) teaches
something that's very important in hacking:
how memory works.
Python or Ruby are high-level, powerful
scripting languages that can be used to
automate various tasks.
Perl is a reasonable choice in this field as
well, while PHP is worth learning because the
majority of web applications use PHP.
Bash scripting is a must. That is how to
easily manipulate Unix/Linux systems—
writing scripts, which will do most of the job
for you.
Assembly language is a must-know. It is the
basic language that your processor
understands, and there are multiple
variations of it. At the end of the day, all
programs are eventually interpreted as
assembly. You can't truly exploit a program
if you don't know assembly.
