As the hacker is the most skilled IT disciplines, it requires a wide knowledge of IT technologies. To be a great hacker, one must know many skills. Use this list as a starting ground for what you need to study in future.
1. Networking Skills
You need to understand the basics of networking, such as DHCP, NAT, Subnetting, IPv4, IPv6, Public v Private IP, DNS, Routers and switches, VLANs, OSI model, MAC addressing, ARP.
As we are often exploiting these technologies, the better you understand how they work
2. Linux Skills
It is extremely critical to develop Linux skills to become a hacker. Nearly all the tools we use as a hacker are developed for Linux and Linux gives us capabilities that we don't have using Windows. Start using Linux if you want to become Hacker.
3. Wireshark or Tcpdump
Wireshark is the most widely used sniffer/protocol analyzer, while tcpdump is a command line sniffer/protocol analyzer. Both can be extraordinarily useful in analyzing TCP/IP traffic and attacks.
You need to become proficient in using one of the virtualization software packages such as VirtualBox or VMWare Workstation. Ideally, you need a safe environment to practice your hacks before you take them out in real world. A virtual environment provides you a safe environment to test and refine your hacks before going live with them.
5 .Security Concepts & Technologies
A hacker understands security concepts and technologies. The only way to overcome the roadblocks established by the security admins is to be familiar with them. The hacker must understand such things as PKI (public key infrastructure), SSL (secure sockets layer), IDS (intrusion detection system), firewalls, etc.
6. Wireless Technologies
In order to be able to hack wireless, you must first understand how it works. Things like the encryption algorithms (WEP, WPA, WPA2), the four-way handshake, and WPS. In addition, understanding such as things as the protocol for connection and authentication and the legal constraints on wireless technologies.
7. Database Skills
If you want to be able to proficiently hack databases, you will need to understand databases and how they work. This includes the SQL language. Recommend to mastery of one of the major DBMS's such SQL Server, Oracle, or MySQL.
8. Web Applications
Web applications are probably the most fertile ground for hackers in recent years. The more you understand about how web applications work and the databases behind them, the more successful you will be. In addition, you will likely need to build your own website for phishing and other nefarious purposes.
Without scripting skills, the hacker will be relegated to using other hackers' tools. This limits your effectiveness. Every day a new tool is in existence loses effectiveness as security admins come up with defenses.
To develop your own unique tools, you will need to become proficient at least in one of the scripting languages including the BASH shell. These should include one of Perl, Python, or Ruby.
To become good hacker, you must not be caught! You can't become a pro hacker sitting in a prison cell for 5 years. The more you know about digital forensics, the better you can become at avoiding and evading detection.
11. Advanced TCP/IP
The beginner hacker must understand TCP/IP basics, but to rise to the master level, you must understand in intimate details the TCP/IP protocol stack and fields. These include how each of the fields (flags, window, df, tos, seq, ack, etc.) in both the TCP and IP packet can be manipulated and used against the victim system to enable MitM attacks, among other things.
Although one doesn't need to be a cryptographer to be a good hacker, the more you understand the strengths and weaknesses of each cryptographic algorithm, the better the chances of defeating it. In addition, cryptography can used by the hacker to hide their activities and evade detection.
13. Reverse Engineering
Reverse engineering enables you to open a piece of malware and re-build it with additional features and capabilities. Just like in software engineering, no one builds a new application from scratch. Nearly every new exploit or malware uses components from other existing malware.
14. Think Creatively
There is ALWAYS a way to hack a system and many ways to accomplish it. A good hacker can think creatively of multiple approaches to the same hack.
15. Problem-Solving Skills
A hacker is always coming up against seemingly unsolvable problems. This requires that the hacker be accustomed to thinking analytically and solving problems. This often demands that the hacker diagnose accurately what is wrong and then break the problem down into separate components. This is one of those abilities that comes with many hours of practice.
