Top 10 powerful Hacking Tools in 2019.

If hacking is performed to identify the potential threats to a computer or network then it will be an ethical hacking.

Ethical hacking is also called penetration testing, intrusion testing, and red teaming.

Hacking is the process of gaining access to a computer system with the intention of fraud, data stealing, and privacy invasion etc., by identifying its weaknesses.

Ethical Hackers:

A person who performs the hacking activities is called a hacker.

There are six types of hackers:

The Ethical Hacker (White hat)
Cracker
Grey hat
Script kiddies
Hacktivist
Phreaker

A security professional who uses his/her hacking skills for defensive purposes is called an ethical hacker. To strengthen the security, ethical hackers use their skills to find vulnerabilities, document them, and suggest the ways to rectify them.

Companies that provide online services or those which are connected to the internet, must perform penetration testing by ethical hackers. Penetration testing is another name of ethical hacking. It can be performed manually or through an automation tool.

Ethical hackers work as an information security expert. They try to break the security of a computer system, network, or applications. They identify the weak points and based on that, they give advice or suggestions to strengthen the security.

Programming languages that are used for hacking include PHP, SQL, Python, Ruby, Bash, Perl, C, C++, Java, VBScript, Visual Basic, C Sharp, JavaScript, and HTML.

What is the process of hacking or phases of hacking?
Hacking is broken up into six phases:The more you get close to all phases,the more stealth will be your attack.

1-Reconnaissance-This is the primary phase of hacking where hacker tries to collect as much as information as possible about the target.It includes identifying the target,domain name registration records of the target, mail server records,DNS records.The tools that are widely used in the process is NMAP,Hping,Maltego, and Google Dorks.

2-Scanning-This makes up the base of hacking! This is where planning for attack actually begins! The tools used in this process are Nessus,Nexpose,and NMAP. After reconnaissance the attacker scans the target for services running,open ports,firewall detection,finding out vulnerabilities,operating system detection.

3-Gaining Access-In this process the attacker executes the attack based on vulnerabilities which were identified during scanning! After the successful, he get access to the target network or enter in to the system.The primary tools that is used in this process is Metasploit.

4-Maintaining Access-It is the process where the hacker has already gained access in to a system. After gaining access the hacker, the hacker installs some backdoors in order to enter in to the system when he needs access in this owned system in future. Metasploit is the preffered toll in this process.

5-Clearning track or Covering track-To avoid getting traced and caught,hacker clears all the tracks by clearing all kinds of logs and deleted the uploaded backdoor and anything in this process related stuff which may later reflect his presence!

6-Reporting-Reporting is the last step of finishing the ethical hacking process.Here the Ethical Hacker compiles a report with his findings and the job that was done such as the tools used,the success rate,vulnerabilities found,and the exploit process.

About Solidity

The solidity programming language is the language used to write smart contracts on the Ethereum blockchain. As of my initial writing of this chapter the current compiler version was 0.6.6. However, the versions change rapidly. For example, when I started coding in solidity 2 years ago, solidity was in version 4 and now its version 7 with major library and coding stylistic requirement updates in version 5.

So, note that when compiling your code for labs its best to use the version sited in that particular example. This is easily achieved in the online compilers, by selecting the compiler version from the dropdown menu. If you would like to give yourself a small challenge, use the latest compiler version and try to modify the code to work with it. Usually this just requires a few minor modifications and can be a good learning experience under the hood of how Solidity works and what has changed.

Solidity is very similar to writing JavaScript and is fully object oriented. In the intro chapters we will attempt to provide a quick overview of solidity understanding needed for a penetration tester. This will not be full guide to programming, as programming is considered to be a pre-requisite to application hacking. Instead this chapter will be a gentle introduction of needed concepts you will use throughout this book. Solidity is also a needed pre-requisite for understanding the rest of the information and its associated exploitation course.

However, as long as you understand general programming concepts then you should have no trouble understanding solidity. It is a relatively easy language to get up and running with quickly in comparison to more mature languages like C++ and Java which may take a more significant amount of time to learn.

The most important thing to understand with solidity is that unlike traditional languages, solidity handles transactions of monetary value by default. Meaning you don't need to attach to a payment API to add transactions to your applications. Payment functionality is baked into the language as its primary purpose and for usage with the Ethereum blockchain. All that's needed for financial transactions in solidity is a standard library transfer function, and you can easily send value to anyone's public address.

For example, the following simple function will transfer a specified amount of Ether to the user calling the function provided they have a large enough balance to allow the transfer. But lets not dive into that just yet.

1.  function withdraw (uint amount) {

2.     require (amount <= balances[msg.sender]);

3.     msg.sender.transfer(amount);

4.  }

Structure of a Smart Contract

Rather than discuss payments at this point, let's not jump to far ahead of ourselves. We need to understand the structure of a smart contract. Let's take a look at a Hello World example. We will analyze all of the key aspects that make solidity different then other languages you may currently understand.

You can easily follow along with this on http://remix.ethereum.org which is a free online IDE and compiler for coding in solidity. A full video walk through of Remix is included later on in this chapter. Remix contains in-browser compilers and virtual environments that emulate block creation and allow you to send and receive transactions. This is a powerful development tool and absolutely free to use.

Below is the simple code example we will analyze before moving on to a live walk through.

1.  pragma solidity 0.6.6;

2.

3.  contract HelloWorld {

4.

5.     constructor () public payable {

6.           //This is a comment

7.           //You can put your configuration information here

8.     }

9.

10.   function hello () public pure returns (string memory) {

11.                  return "Hello World";

12.         }

13.}

There is a lot going on in this small program so I will try to break it down as simple as possible. In the first line, we have the pragma statement which is required at the top of each program to let the compiler know which version of solidity this code was written for. As I said earlier, these versions change rapidly due to the evolving technology and many changes are implemented into each new version. So, the compiler needs to know which version you intended this to run on.

On line 3 is the word "contract" followed by whatever name you wish to call your contract. The contract's functionality is then enclosed in curly braces. This is similar to creating a class in any other language. It's a block of associated code that can be inherited, or interfaced with and contains its own variables and methods.

On line 5 contained within the contract curly braces we have a constructor denoted by the word "constructor". The constructor is run one time at contract creation and used to setup any variables or details of the smart contract. This is often used for creating an administrator of the contract or other items that are needed prior to contract usage.

Functions and variables within Solidity also have various types and visibility set with their creation. In this case also on line 5 you will see the words "public" and "payable" used to describe the constructor.

Public you may be familiar with as it's a common visibility keyword used in other languages denoting that anyone can call this function. There are other visibility types in Solidity listed below, we will cover each of these in more detail as we use them to our advantage when hacking smart contracts:

Public

This allows anyone to call and use this function

Private

This allows only the current contract and its functions to call it directly.

Internal

This is similar to private except it also allows derived contracts to use its functionality

External

External can only be called externally by other contracts unless the "this" keyword is used with the function call.

The second keyword in the constructor definition "payable" you may not be familiar with unless you have worked on blockchain projects. The word payable within solidity is needed on any item that can receive Ether. So, by setting the constructor as payable we can send a base amount of Ether to the contract when its deployed. This will add an initial monetary liquidity for whatever functionality the contract is providing. For example, if this were a gambling game, we would need some initial Ethereum to payout our winners before our revenues catch up with our payouts and we start collecting large sums of failed gambling revenue.

Within the constructor is an example of how comments are handled in solidity, the simple double forward slash is used like in most languages. Comments function in the same way as any other language in that they are not processed and they are ignored by the compiler but are useful for understanding the code you wrote later after you have taking time apart from reading your code.

Finally, we have our simple hello function starting on line 10. Again, there is a lot going on here. First is the name of the function with parentheses that can contain arguments like in any other language. However, this function does not take arguments.

You will notice two more keywords in the function definition "pure" and "returns". Returns is simply the way the function denotes that it will return a value to the user, which it then states directly after it what type of variable it returns. In this case, it returns a string in memory. We will talk about memory and storage later on and the security implications of them.

Next is the word "Pure" there are a couple types of functions in Solidity which will list below with a brief description.

View

This type of function does not modify or change the state of the contract but may return values and use global variables.

Pure

A pure function is a function which is completely self-contained in that it only uses local variables and it does not change the state of the smart contract.

Finally, in line 11 we return our string to the user who called the function. In the context of a user, this could be a physical user using an application or smart contract functionality or it could actually be another smart contract calling the function.

Hands on Lab – Remix HelloWorld

Now that we talked over in detail all the new concepts to solidity programs using a small example, lets compile and run this code on remix.ethereum.org.

Action Steps:

ü Browse to remix.etherum.org
ü Type out the the code from above (Do not copy Paste it)
ü Compile and deploy the code
ü Review the transaction in the log window

Intro to the Remix Development Environment Video

In Remix create a new file and type out the example helloworld code. I would suggest that you actually type out all of the examples in this book. They will not be exhaustive or long and will provide you great value and make you comfortable when it comes to writing your own exploits and using the compilers and tools. These are all essential tools to your understanding.

Within your remix environment, you will want to select the compiler version 0.6.6 to ensure that this code runs correctly. If you typed out the code correctly you should not receive any errors and you will be able to deploy and interact with it. In the following video we will walk you through that process and explain some nuances of solidity.

Explaining and Compiling HelloWorld Video:

Lets now quickly review a few key points about the transaction that you saw within the video when compiling your code. This transaction is shown below.

__________________________________________________________________________________

call to HelloWorld.hello

CALL

from 0xBF8B5A94eD4dFB45089b455B1A0e296D6669c625

to HelloWorld.hello() 0xADe285e11e0B9eE35167d1E25C3605Eba1778C86

transaction cost 21863 gas (Cost only applies when called by a contract)

execution cost 591 gas (Cost only applies when called by a contract)

hash 0x14557f9552d454ca865deb422ebb50a853735b57efaebcfc9c9abe57ba1836ed

input 0x19f...f1d21

decoded input {}

decoded output {

"0": "string: Hello World"

}

logs []

_________________________________________________________________________________

The output above is a hello transaction which contains the relevant data retrieved when you executed the hello function in the video. The first important thing to notice is the word "CALL". In solidity there are call and send transactions. The difference between the two is whether they change the state of the blockchain or not. In this case we did not change the state, we only retrieved information so a CALL was issued. If we were changing variables and sending values then a SEND transaction would have been issued instead.

Next you will see the "From" address which should correspond with the address you used to call the transaction. The "To" field should be the address the smart contract was given when you deployed the smart contract. You can view this on your deployment screen next to the deployed contract name by hitting the copy button and pasting it somewhere to see the full value.

You will then see the costs and gas associated with the transaction. Costs change based on the size of the contracts and the assembly code created by the compiler. Each instruction has a cost. We will cover that later when we do a bit of debugging and decompiling.

Finally take note of the Decoded Output which contains the return string of "Hello World".

Summary

If you are new to solidity or new to programming in general this might have been a lot of information. In the next chapter we cover a few more key solidity concepts before moving on to exploiting vulnerabilities where a much more in depth understanding of how solidity works and its security implications will be explored.
