What is ethical hacking, and how does it work?

Ethical hacking is the practice of identifying and testing vulnerabilities in a system to improve its security and prevent unauthorized access.

Moral hacker attack, also known as "white hat" hacker attack, refers to the process of identifying and using loopholes in computer software or network to assess its security and provide improvements. Ethical personal behavior of hackers should be carried out with the approval and knowledge of the department or individual with the system under test.

The purpose of moral hackers is to find vulnerabilities in the system before intentional hackers are likely to exploit system software vulnerabilities. Like a means and method used by intentional hackers, moral hackers use the same means and methods, but their purpose is to improve safety, not to cause harm.

Here's how moral hackers generally work.

Planning and investigation

Moral hackers investigate the target system software or network to obtain information suitable for searching for vulnerabilities. This may include information about IP addresses, website domain names, network topologies, and other objective facts.

Already scanned

In order to find a comprehensive open port, service and other details suitable for the target of the attack, moral hackers apply vulnerability scanning tools.

Enumerated type

In order to obtain unauthorized browsing, moral hackers find more accurate information in the overall target system software, such as user accounts, shared networks, and other small details.

Vulnerability analysis

In order to find vulnerabilities in the overall target system, such as outdated mobile phone software, inappropriate or inadequate login passwords, moral hackers work together with automated tools for human programming processes.

Development and design

Moral hackers expect to use the vulnerabilities found to obtain unauthorized browsing of the target system or the Internet.

Report

Finally, ethical hackers record the vulnerabilities found and offer suggestions to improve product security. Subsequently, enterprises or individuals will use this report to solve the security shortcomings of the system software or network, and improve the overall safety factor.

Moral hackers can be a valuable and proprietary tool for units and individuals who need to ensure their Internet and security. Moral hackers can help avoid data leaks and other security problems by finding vulnerabilities before they are exploited by criminal hackers.

Can blockchain be invaded by hackers?

Although the technology behind the blockchain is designed to be secure, there are still some network attack methods that can exploit vulnerabilities in the system and endanger the integrity of the blockchain. Here are some ways in which blockchains can be attacked by hackers:

  • 51% attack: 51% attack refers to a good network attack to control the computer resources of the blockchain Internet. As a result, a cyber attack is likely to reverse trade and change the blockchain, which costs two times.
  • Blockchain intelligent contract utilization: if blockchain intelligent contract has a loophole, network attacks can take advantage of this loophole to steal digital currency or control blockchain.
  • Malicious programs: in the blockchain on the network, malicious programs can be deployed to harm the security of special customers. For example, the public key needed to browse a user's encrypted currency wallet may be stolen by a network attack using a malicious program.
  • Distributed denial of Service (DDoS) attack: DDoS is a hacker attack that uses several attacked software to push total traffic to the overall target URL or network, making it impossible for users to open the site or network. Secure DDoS attacks can be used to engulf blockchain Internet platform traffic and efficiently terminate it completely.

Therefore, it is very important to enhance vigilance and take effective measures to ensure the use of the block chain and the security on the platform.

The importance of moral hackers in the security of blockchain

Moral hacking under blockchain is an entirely new field dedicated to discovering shortcomings and potential attacks under blockchain's system. Because of its security and blockchain technology, blockchain technology is becoming more and more popular, but it is not immune to security risks. Moral hackers can use a variety of means to detect the security of blockchain systems in order to see all the hidden shortcomings.

Here are some ways to apply moral hackers to the blockchain:

  • Financial audit of intelligent contracts: intelligent contracts are completed automatically, in which the transaction rules between the buyer and the seller are immediately loaded into the coding line. Smart contracts need to be audited by moral hackers to see any deficiencies or shortcomings that may be exploited.
  • Internet website penetration testing: in order to find potential vulnerabilities in blockchain networks, moral hackers may conduct web site penetration testing. They can use devices such as Nessus and OpenVAS to find known vulnerability nodes, scanner the Internet to explore typical attacks, and find all possible shortcomings.
  • Analysis of consensus mechanism: consensus mechanism is a major field of block chain science and technology. Moral hackers can examine consensus mechanisms to find all shortcomings that may be exploited in optimization algorithms.
  • Privacy and security detection: blockchain system software is committed to information confidentiality and security, but they are not necessarily immune to attack. Moral hackers can detect the overall privacy and security of the blockchain to see all hidden shortcomings.
  • Cryptographic algorithm analysis: block chain technology obviously depends on cryptographic algorithm moral hackers can check the block chain comprehensive login password agreement, in order to find any shortcomings in the technical implementation.

In a word, moral hackers can become a meaningful and special tool in identifying and dealing with security risks in blockchain systems. According to identifying vulnerabilities and offering suggestions to improve product security, moral hackers can help ensure security integrity based on the usage derivatives of the block chain.
