Buffer Overflow: A Beginner’s Guide for Ethical Hacking Introduction
A buffer overflow, also known as a buffer overrun, is a common and dangerous software bug that can occur in various programming languages. It happens when a program attempts to write more data to a buffer than its allocated memory can hold. This causes the data to overflow the buffer and overwrite adjacent memory locations, potentially leading to unexpected and harmful behavior.
Metasploit: The Ultimate Guide for Penetration Testing Metasploit is the world’s most popular open-source penetration testing framework. It provides a comprehensive collection of tools and resources for identifying, exploiting, and mitigating security vulnerabilities. Whether you’re a seasoned security professional or just starting out in the field, Metasploit is a valuable tool that can help you improve your security posture.
What is Metasploit? Metasploit is a modular framework that allows you to:
Chay published on Authentication Authentication methods are commonly categorized into three types based on the number of factors or elements used to verify a user’s identity. These are often referred to as:
Type 1 (Single-factor authentication):
Relies on a single element (e.g., password). Basic and less secure. Type 2 (Two-factor authentication or 2FA):
Uses two different elements (e.g., password + SMS code). Provides higher security than single-factor. Type 3 (Multi-factor authentication or MFA):
Chay published on What is Vulnerability A vulnerability refers to a weakness in the design or implementation of a system that can be exploited to compromise the security of the system. It is frequently a security loophole that enables an attacker to enter the system by bypassing user authentication. There are generally two main causes for vulnerable systems in a network, software or hardware misconfiguration and poor programming practices. Attackers exploit these vulnerabilities to perform various types of attacks on organizational resources.
Chay published on In the realm of cybersecurity, “enumeration” refers to the process of extracting information or details about a target system or network. It involves systematically gathering data by probing the system for vulnerabilities, services, users, shares, or any other relevant information that could be exploited or used in an attack. Enumeration is often a critical phase in penetration testing or ethical hacking, where the goal is to identify potential entry points or weaknesses that could be exploited to gain unauthorized access.

TCP vs UDP TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different transport layer protocols used for transmitting data over the internet. Here’s a brief comparison:
TCP (Transmission Control Protocol): Connection-oriented: Establishes a reliable connection before data exchange. Reliability: Provides error checking, retransmission of lost data, and in-order delivery of packets. Slower: Due to the overhead of reliability mechanisms, it can be slower for certain applications.
Chay published on Footprinting Footprinting in cybersecurity refers to the process of gathering information about a target system or network to create a blueprint or map of its infrastructure and the organization’s digital footprint. It’s an essential phase in the pre-attack reconnaissance process used by ethical hackers, security professionals, or attackers to understand and analyze the potential vulnerabilities and weaknesses of a target.
Objectives of Footprinting Network Discovery: Identify active hosts, domains, IP ranges, network topology, and infrastructure details.
Chay published on CIA Triad The CIA Triad is a foundational model in information security used to guide policies for protecting sensitive information. It stands for:
Confidentiality: Ensuring that information is only accessible to those who are authorized to access it. It involves preventing unauthorized access or disclosure of information.
Integrity: Guarantees that information is accurate, reliable, and has not been altered by unauthorized individuals or malicious software. Integrity ensures that data remains unchanged and trustworthy.
Comma Separated Values (CSV) is a widely used file format for storing and exchanging tabular data. Python provides various libraries and modules to work with CSV files, making it easy to read, write, and manipulate data in this format. In this article, we’ll explore the basics of working with CSV files in Python and provide practical examples to help you get started.
1. Introduction to CSV Files CSV files are simple text files that store tabular data in plain text, where each row represents a record, and columns are separated by a delimiter, typically a comma.
Introduction Hyper-V, Microsoft’s virtualization platform, is a powerful tool for running multiple operating systems on a single physical machine. One of its features is the ability to create Internal Host-Only Networks, which can be incredibly useful for various purposes. However, some users have reported that using these networks can slow down the host machine’s internet speed. In this article, we’ll explore the issue and present a solution by setting a low metric value for the host network adapter.
