VMware is a program vendor for cloud computing and virtualization. They utilize virtualization technology in which a hypervisor is installed on the physical server, allowing the operation of numerous virtual machines (VMs) on the same physical server.

When you install Workstation Pro on a Windows or Linux host system, a NAT network (VMnet8) is set up for you. When you use the New Virtual Machine wizard to create a typical virtual machine, the wizard configures the virtual machine to use the default NAT network.

With NAT, a virtual machine does not have its own IP address on the external network. Instead, a separate private network is set up on the host system. In the default configuration, virtual machines get an address on this private network from the virtual DHCP server.

A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs.

HTTP operates at Application Layer whereas HTTPS operates at Transport Layer. HTTP by default operates on port 80 whereas HTTPS by default operates on port 443. HTTP transfers data in plain text while HTTPS transfers data in cipher text (encrypt text).

Authentication Hacking: What are Authentication Hacking Attacks?

Such attacks have been known to rely on a user having an authenticated session present for ethical hacker.

As with any authentication mechanism, the password reset process should have protection against automated or brute-force attacks.

A path traversal attack (also known as directory traversal) aims to access files and directories that are stored outside the web root folder.

As defined by OWASP, the File Inclusion vulnerability allows an attacker to include a file, usually exploiting a “dynamic file inclusion” mechanisms implemented in the target application. The vulnerability occurs due to the use of user-supplied input without proper validation.

LFI is a web vulnerability that results from mistakes at the website or web application programmers' end. A hacker can take advantage of this vulnerability to include malicious files which are then executed by the vulnerable website or web application.

Remote file inclusion (RFI) is an attack targeting vulnerabilities in web applications that dynamically reference external scripts. The perpetrator's goal is to exploit the referencing function in an application to upload malware (e.g., backdoor shells) from a remote URL located within a different domain.

A cookie with the HttpOnly attribute is inaccessible to the JavaScript Document.cookie API; it is sent only to the server.

Secure cookies are a type of HTTP cookie that have Secure attribute set, which limits the scope of the cookie to "secure" channels (where "secure" is defined by the user agent, typically web browser).

Using SQL Injection to Bypass Authentication In this lecture we will demonstrate a technique to bypass the authentication of a vulnerable login page using SQL Injection.

SQL Injection over Insert Statement.
Ethical hacking involves a hacker agreeing with an organization or individual who authorizes the hacker to levy cyber attacks on a system or network to expose potential vulnerabilities. An ethical hacker is also sometimes referred to as a white hat hacker. Many depend on ethical hackers to identify weaknesses in their networks, endpoints, devices, or applications. The hacker informs their client as to when they will be attacking the system, as well as the scope of the attack. An ethical hacker operates within the confines of their agreement with their client. They cannot work to discover vulnerabilities and then demand payment to fix them. This is what gray hat hackers do. Ethical hackers are also different from black hat hackers, who hack to harm others or benefit themselves without permission.

Boolean-based SQL injection is a technique which relies on sending an SQL query to the database.
Ethical hacking is a good career because it is one of the best ways to test a network. An ethical hacker tries to locate vulnerabilities in the network by testing different hacking techniques on them. In many situations, a network seems impenetrable only because it hasn’t succumbed to an attack in years. However, this could be because black hat hackers are using the wrong kinds of methods. An ethical hacker can show a company how they may be vulnerable by levying a new type of attack that no one has ever tried before. When they successfully penetrate the system, the organization can then set up defenses to protect against this kind of penetration. This unique security opportunity makes the skills of an ethical hacker desirable for organizations that want to ensure their systems are well-defended against cybercriminals.

What is a time-based blind SQL injection? In a time-based SQL injection, the attacker sends SQL queries to the database, which force the database to wait for a specified amount of time before responding.
In addition to proficiency in basic computer skills and use of the command line, ethical hackers must also develop technical skills related to programming, database management systems (DBMS), use of the Linux operating system (OS), cryptography, creation and management of web applications and computer networks like DHCP, NAT, and Subnetting. Becoming an ethical hacker involves learning at least one programming language and having a working knowledge of other common languages like Python, SQL, C++, and C. Ethical hackers must have strong problem-solving skills and the ability to think critically to come up with and test new solutions for securing systems. Ethical hackers should also understand how to use reverse engineering to uncover specifications and check a system for vulnerabilities by analyzing its code.

In this lecture, we will use SQLMap to detect and exploit an SQL Injection vulnerability and will obtain usernames and passwords of an application with it.

Error-based: sqlmap replaces or appends to the affected parameter a database-specific error message provoking statement and parses the HTTP response.

Sqlmap can detect and exploit various types of SQL injection, including Time and Boolean-based blind SQL injection.

Command injection is a cyber attack that involves executing arbitrary commands on a host operating system (OS). Typically, the threat actor injects the commands by exploiting an application vulnerability, such as insufficient input validation.

The ability to execute system commands via a vulnerable web application makes command injection a fruitful attack vector for any hacker.

Similar to SQL Injection, XPath Injection attacks occur when a web site uses user-supplied information to construct an XPath query for XML data.

SMTP header injection vulnerabilities arise when user input is placed into email headers without adequate sanitization, allowing an attacker to inject additional headers with arbitrary values.
Ethical hacking is legal because the hacker has full, expressed permission to test the vulnerabilities of a system. An ethical hacker operates within constraints stipulated by the person or organization for which they work, and this agreement makes for a legal arrangement. An ethical hacker is like someone who handles quality control for a car manufacturer. They may have to try to break certain components of the vehicle such as the windshield, suspension system, transmission, or engine to see where they are weak or how they can improve them. With ethical hacking, the hacker is trying to “break” the system to ascertain how it can be less vulnerable to cyberattacks. However, if an ethical hacker attacks an area of a network or computer without getting expressed permission from the owner, they could be considered a gray hat hacker, violating ethical hacking principles.

If an attacker is able to inject PHP code into an application and have it executed, they are only limited by what PHP is capable of.
The Certified Ethical Hacker (CEH) certification exam supports and tests the knowledge of auditors, security officers, site administrators, security professionals, and anyone else who wants to ensure a network is safe against cybercriminals. With the CEH credential, you can design and govern the minimum standards necessary for credentialing information that security professionals need to engage in ethical hacking. You can also make it known to the public if someone who has earned their CEH credentials has met or exceeded the minimum standards. You are also empowered to reinforce the usefulness and self-regulated nature of ethical hacking. The CEH exam doesn’t cater to specific security hardware or software vendors, such as Fortinet, Avira, Kaspersky, Cisco, or others, making it a vendor-neutral program
