Ethical Hacking on the Internet


Hacking on the Internet is a natural process that leads to a violation of confidentiality and confidential information. Weaknesses in the system or loopholes in the network were identified, and personal data was also available. Therefore, hacking is also known as unauthorized intrusion. Nonetheless, hacking was not always perceived as theft and was used for productive purposes. This type of hacking, which includes good intentions, is known as ethical hacking.
Ethical Hackers and Their Purpose
People who specialize in the ethical hacking process are known as ethical hackers. These are professionals who hack into a system or network to find possible crashes, pitfalls, and vulnerabilities that could be exploited by black hat hackers or crackers. The skills and thinking of ethical hackers are equal to malicious hackers, but they can be trusted. Ethical hackers are certified and authorized to perform hacking on target systems. An ethical hacker has the legal right to access the target’s personal data and change the target’s system. The skills that an ethical hacker possesses can be used to increase cyber security.
Along with hackers in white and black hats, another category of hackers was discovered who work closely with ethical hackers but face some social consequences. These hackers are known as gray hackers who break into technical and network systems for good reasons, for example, help organizations solve security problems, but are not authorized. Gray hat hackers carry out ethical hacks, but their unauthorized approach leads to a lack of public recognition. Ethical hackers are hired by agencies, companies, and organizations to monitor their security.
Hacking Phases
Hacking is not a single-phase process. Five steps are performed to complete the hacking process:
• Intelligence
• Scan
• Access
• Maintain access
• Cleaning tracks
A hacker does not have to follow these steps in sequential order. However, the implementation of these steps in the same order can lead to accurate hacking. In the initial stage, the maximum information about the network, hosts and the people involved is collected to perform a fingerprint or intelligence. This can be done either by directly approaching the goal and gaining knowledge or by using indirect methods such as websites, social sites, etc. without a direct approach to the target. Data collection provides a deep understanding of the system under surveillance.
The second stage involves a thorough scan of the target. Three processes are involved in the scanning phase; port scanning, vulnerability scanning and network mapping. For further processing of the target, technical means are used; for example, a vulnerability scanner is installed in the target network to identify security threats. 
In the third step, the hacker finally gains access to the target system or network using various methods and tools. When accessing the system, the hacker must reach the administrator level in order to change or set the data in accordance with the requirement. Modification of network or system data occurs after installing a specialized application that allows a hacker to change network settings.
The process of maintaining access is very important since, after the loss of target access, the process of obtaining it will be repeated again and again. Specific files that support access are used for this purpose if the hacker's task has not yet been completed. Otherwise, if the hacker made the necessary changes to the system, access is not required to be maintained. The final hacking step involves clearing the track to erase all traces and evidence that the system was hacked. All created folders, installed applications, and changed registry values are deleted at this point. The changes are made unrecognizable so that the hacking process is not detected.
Process, Tool and Technology
Since each process requires several specialized tools and methods to complete the task, the hacking process also requires the right tools. According to the CDN, it's essential to be aware of personal and technical limitations when it comes to using ethical hacker tools. Since each equipment contains minor inaccuracies, it is not necessary that when using the right tools, all possible vulnerabilities in the system are detected. However, if more tools are used in the hacking process, the likelihood of more significant inaccuracy in the results is reduced. Essential skills and processes that a hacker should be aware of include HTTP, HTTPS and other network protocols, authentication methods, network and firewall architectures, port information, web applications, web server configurations, database settings and programming languages such as HTML, Ruby, Python, JavaScript. This talent allows the hacker to understand most target networks and systems without any difficulties. These are the primary abilities acquired by a hacker to understand his goals and complete professionalism in the implementation of the hacking process.
Knowledge in networks and systems is not enough to complete the hacking process. Special tools and software applications are designed to perform ethical hacking accurately. They simplify the hacking process and are convenient for use by hackers who are at the initial stage. Some of these tools include vulnerability scanners, packet analyzers, password crackers, hacking equipment, applications, and port scanners. CDN draws on other commercial and open ethical hacking tools such as Nmap, Ether Peek WebInspect, Ethereal, Kismet, Nikto, QualysGuard, SuperScan, ToneLoc, LC4, LANguard Scanner for network security, Internet scanner, Nessus, etc. These tools and equipment are commercially available to professional ethical hackers and are included with the manual for further convenience.

The Biggest Threats in Cyber Security

AI-Driven Attacks We’ve seen it in science fiction films but it looks like reality that computers are learning to attack on their own. Different cyber security platforms are embracing the modern AI to overcome these attacks but hackers are also using the same technology to launch new attacks at their end. Experts suggest that the hackers adopt powerful AI tools for automated attacks and expand their domain in various cyber security reports. Adversarial AI attacks are particularly worrying, because they are so powerful. Theft of data in the past attacks caused a great deal of fear due to the money, time and effort required to carry it out. Now AI has made it easier for hackers to execute several types of attacks within the same time frame and using very less energy. Even with the few lines of codes, hackers can now solve the problem of years into seconds and gain access throughout the network. Phishing Phishing is among the oldest scams and is considered green as ever

Spam vs. Phishing: What Is the Difference?

Both spam and phishing are related to social engineering, a general term for any activity in which an attacker is trying to manipulate you into revealing personal information. Passwords, account credentials, social security numbers--you should always think twice before giving out this information. Always verify who is really on the other end of the line. What is spam? Spam is unsolicited and unwanted junk email sent out in bulk to a wholesale recipient list. Typically, spam is sent for commercial purposes. However, spam email can also contain a malicious attempt to gain access to your computer, so email security becomes an important defense. What is phishing? Phishing is a common type of cyber attack that everyone should learn about to protect themselves. Phishing attacks are fraudulent communications that appear to come from a reputable source. The goal is to trick the recipient into giving away sensitive data or to install malware in the form of spyware on the victim&

Threat Hunting Steps

The process of proactive cyber threat hunting typically involves three steps: a trigger, an investigation and a resolution. Step 1: The Trigger A trigger  points threat hunters to a specific system or area of the network for further investigation when advanced detection tools identify unusual actions that may indicate malicious activity. Often, a hypothesis about a new threat can be the trigger for proactive hunting. For example, a security team may search for advanced threats that use tools like fileless  malware  to evade existing defenses. Step 2: Investigation During the  investigation phase , the threat hunter uses technology such as  EDR (Endpoint Detection and Response)  to take a deep dive into potential malicious compromise of a system. The investigation continues until either the activity is deemed benign or a complete picture of the malicious behavior has been created. Step 3: Resolution The resolution phase  involves communicating relevant malicious activity
