In a brute-force attack known as "password spraying, " an attacker tries to obtain unauthorized access to numerous user accounts by repeatedly trying a limited number of popular passwords (such as "Password123, " "Welcome1, " and "123456") against numerous usernames. In contrast to conventional brute force attacks, which employ several passwords to target a single account, password spraying aims to prevent account lockouts that result from repeatedly unsuccessful login attempts on a single account. How Does Password Spraying Work?Here is a brief overview of how password spraying works -Obtaining Usernames: Hackers frequently obtain lists of email addresses or usernames ... Read More
Although both AIX and GhostBSD are operating systems, their functions are quite different. Read this article to learn how AIX is different from GhostBSD. What is GhostBSD? The GhostBSD Team and Eric Turgeon produced this open source operating system. Influenced by the TrueOS operating system, it is a Unix-like operating system. The desktop environment by default is MATE. It is simply used by workstations and desktop computers. Previously, the default desktop environment was GNOME. 2009 saw the debut release of GhostBSD. In terms of stability, GhostBSD 19.10 is the latest version. It has a monolithic kernel that is divided into ... Read More
In this article, we will learn to print the upper star triangle pattern in Java. Printing patterns is a common exercise to strengthen the understanding of loops in programming. One of the most popular patterns is the Upper Star Triangle, which visually resembles an inverted right-angled triangle of stars aligned from the top. Below is a demonstration of the same − Input Enter the number of rows : 8 Output The upper star triangle star pattern : * ... Read More
In this article, we will learn to convert integers to String with Map in Java. The Stream API has become an essential tool for processing collections of data in a more declarative and readable way. Instead of using traditional loops, streams allow developers to filter, map, and perform other operations on data with minimal code Problem Statement Given an integer, we need to convert it to its string representation where the integer is treated as a character (e.g., 5 becomes "5", 10 becomes "10"). We'll use a Map to define the integer-to-string mappings and retrieve the string equivalent for a ... Read More
In Java, Converting a byte array to a hex string means transforming each byte into its hexadecimal representation. byte array: A byte array is a collection of byte values. Each byte is an 8-bit unit of data. Hex String: A hexadecimal (hex) string represents a number in base-16, using digits 0-9 and letters A-F. We represent the A-F in numbers as 10 to 15. The following is our byte array as given below − byte[] b = new byte[]{'p', 'q', 'r'}; We have created a custom method "display" that ... Read More
An array is a linear data structure that stores a group of elements with similar datatypes, in a sequential order. Once we create an array, we can’t change its size, i.e., it can store a fixed number of elements. In this article, we will learn how to write a Java program where we create an array and perform the right rotation using the reversal algorithm. Right Rotation of an Array Let’s understand the term right rotation in the context of an array. In the right rotation of an array, we simply shift the elements of the array to our right till the specified number ... Read More
Problem Description In this problem, we are given a number and have to check whether this number is greater than zero. Using the if-else and ternary approach to check if the given number is greater than zero, equal to zero, or less than zero. In this article, we will discuss how we can find if a given number is greater than zero or not in C++. Prerequisite If-else operator: This operator allows the program to execute certain code blocks based on whether a condition is true or false. Syntax of If-else operator if (condition) { // ...
