Several subgroups of the computer underground with different attitudes and aims use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree, they give more emphasis to a spectrum of different categories, such as white hat, grey hat, black hat and script kiddie.
A Cracker or Cracking is to “gain unauthorized access to a computer in order to commit another crime such as destroying information contained in that system”. These subgroups may also be defined by the legal status of their activities. Continue reading Types of hacker
Following are some must know things for a hacker or you can say requirements of hacker or Skills Required to become a Computer hacker
As a hacker you must have upper hand skills in Operating systems Windows, Linux and Unix. Once you master Linux and Unix you’ll hardly face problem getting yourself on MAC. As we’ll move further we will cover both of them in short and then slowly move our level to advanced.
A hacker must have expertise in field of networking even if you don’t have them you must be knowing about some basic terms used in networking. Please click on following links and try to grasp topics as thoroughly as you can.
The reality is that a hacker should know networking to best level. Just knowing above terms is not sufficient though you’ll not encounter that much problem while learning. We still recommend you buying a book on networking that should cover networking to level of pin points. My personal favor is to book Data Communication And Networking by Behrouz Forouzan
Knowledge About Setting Up And Configuring Servers:
Yes that is necessary for a hacker so when we will move ahead with flow. We will cover configuring IIS 7, Apache, Vertrigo on Windows and Apache on Linux. Both HTTP and FTP servers will be covered.
Absolutely no one can deny all best hackers in world have master hand in programming. Following are must know programming languages but you can even make things work even if you don’t know them. In any case I would recommend you learn programming.
HTML, C, C++, Java, SQL, Python, Perl, PHP and Ruby.
At most basic level my advise will be you must know HTML, C, SQL, PHP and ruby.
Backtrack is platform which is specially crafted and designed for penetration testing. Metasploit is framework that is used to create and experiment with exploits and payloads. Both are must for a hacker today. Alternative to Backtrack is Knoppix Security Edition and Mautrix, if you master Bactrack you’ll easily master both of them. So I will not leave them apart from our list, we’ll also cover them.

Many people on net impressed by the word “hacking” might do a little search on google about learning hacking. No doubt, they are at the right place. I would have rather use words – they are on the right track but will they open up the right door and gain something or they will just end up becoming a victim them self. Continue reading Hacking – Tips for Learner
How Can We Hack
Before start to learn How Can We Hack or Hacking you must have the deep knowledge of hacking means from most basic.
Whenever term hacker comes before many people consider it as a guy sitting inside a room or garage with a bottle or beer and a Laptop or Desktop doing wonders on click of buttons. But the reality check is hacking is not that easy as portrayed in movies and television and term hacker doesn’t mean a computer criminal. Continue reading How Can We Hack ??
As many of newbies asking this quetion so for all these people who are new at this whole Scenerio and do not really understand what hacking is all about and where to begin, I offer up these links to some great places to start learning.
Podcasts: http://www.grc.com/SecurityNow.htm <– This is fantastic for people who are new to the field. If you have the time or motivation, go back and listen to them from day 1, they assume you know very little if anything and hit on all of the major topics in the security field. Fantastic show.
One of my reader ask me about Ethical courses so i try to put little info about top 5 ethical hacking course.And its also a first module on How To Learn Ethical Hacking

It is formally approved by U.S. Department of Defense in both their Information Assurance Technical and Managerial Categories.
A Starting Salary of a CISSP according to Payscale is around $1,29,829 USD
Welcome back in section of How to bye pass firewall. Earlier we discuss about Identification of Firewall in post How to bye pass Firewall. In this post we discuss about tools to bye pass the firewall and study about Its technique.
One of the easiest and most common ways for an attacker to slip by a firewall is by installing network software on an internal system, which communicates by using a port address permitted by the firewall’s configuration
A popular port is TCP port 80, which is normally used by web server
Many firewalls permit traffic using port 80 by default
Byepassing a firewall using HTTP Tunnel
Httptunnel creates a bi-directional virtual data path tunneled in HTTP requests. The requests can be sent via an HTTP proxy, if desired.
Placing Backdoors through Firewall
The Reverse WWW Shell
This backdoor should work through any firewall that allows users to surf the WWW. A program is run on the internal host, which produces a child everyday at a special time.
For the firewall, this child acts like a user; using the browser client to surf the Internet. In reality, this child executes a local shell, and connects to the WWW server operated by the hacker via a legitimate-looking http request, and sends a stand-by signal
The legitimate-looking answer of the WWW server operated by the hacker is, in reality, the command the child will execute on its machine in the local shell.
Hiding behind a Covert channel : Loki
LOKI is an information tunneling program.
LOKI uses Internet Control Message Protocol (ICMP) echo response packets to carry its payload. ICMP echo response packets are normally received by the Ping program, and many firewalls permit the responses to pass
Simple shell commands are used to tunnel inside ICMP_ECHO/ICMP_ECHOREPLY and DNS name lookup query/reply traffic. To the network protocol analyzer, this traffic seems like ordinary packets of the corresponding protocol. However, to the correct listener ( the LOKI2 daemon), the packets are recognized for what they really are.
Tools to Bye Pass Firewall
007 Shell is a covert shell ICMP tunneling program. It works similar to LOKI. 007 Shell works by putting data streams in the ICMP message past the usual 4-bytes (8-bit type, 8-bit code, and 16-bit checksum)
ICMP Shell (ISH) is a telnet-like protocol. It provides the capability of connecting a remote host to an open shell, using only ICMP for input and output The ISH server runs as a daemon on the server side. When the
server receives a request from the client, it will strip the header and look at the ID field. If it matches the server’s ID, then it will pipe the data to “/bin/sh.” It will then read the results from the pipe and send them back to
the client, where the client then prints the data to stdout.
A free circumvent software available online, perhaps powerful enough to bypass any industry level firewall at its default configuration.It enables users to browse any website freely just the same as using the regular browser while it automatically searches the highest speed proxy servers in the background.
AckCmd is a client/server combination for Windows 2000 that opens a remote command prompt to another system (running the server part of AckCmd). It communicates using only TCP ACK segments. This way the client component is able to directly contact the server component through the firewall.
Tor is a system intended to enable online anonymity, composed of client software and a network of servers which can hide information about users’ locations. Tor provides perfect anonymity it makes it more difficult to trace internet traffic to the user, including visits to Web sites, online posts, instant messages, and other communication forms.
This post will familiarize you with Firewall , bypass the firewall and tools to bye pass it.
WHAT IS FIRE WALL?
A hardware device and/or software program which sits between the Internet and the intranet, internet, of an organization
It restricts information that comes to your computer from other computers, giving you more control over the data on your computer and providing a line of defense against people or programs that try to connect to your computer without invitation.
In fact, that’s why its called a firewall. Its job is similar to a physical firewall that keeps a fire from spreading from one area to the next.
Its main objectives are to filter:
what should come in the intranet (inbound traffic) and
what should come out of the intranet (outbound traffic).
TYPES OF FIREWALL
Packet Filtering Firewall : They are usually part of a router and each packet is compared to a set of criteria before it is forwarded, dropped, or a message is sent to the originator.
Circuit level Gateway : they monitor TCP handshaking between packets to determine whether a requested session is legitimate. Information passed to remote computer through a circuit level gateway appears to have originated from the gateway. On the other hand, they do not filter individual packets.
Application level gateways : also called proxies, are application specific. An application level gateway that is configured to be a web proxy will not allow any ftp, gopher, telnet or other traffic through. They offer a high level of security, but have a significant impact on network performance.
Stateful Multilayer Firewalls : combine aspects of the other three types of firewalls. They filter packets at the network layer and evaluate contents of packets at the application layer. They allow direct connection between client and host, and they rely on algorithms to recognize and process application layer data instead of running application specific proxies.
Firewall defense your network using one of two access denial methodologies:
may allow all traffic through unless it meets certain criteria, or
may deny all traffic unless it meets certain criteria
And Criteria to be configured for firewall
So these are four criteria on which your network should be defensed by Anti virus. The next post will be on How to bye pass Firewall
