To answer this question, you need to understand the different types of malicious software and their functionalities. Let's go through each option to understand why it is correct or incorrect:

Option A) Trojan - This option is correct. A Trojan is a type of malicious software that disguises itself as a legitimate program to trick users into installing it. Once installed, a Trojan can create a "backdoor" internet connection, allowing unauthorized access to a user's computer.

Option B) Virus - This option is incorrect. A virus is a type of malicious software that can replicate and spread itself by attaching to other programs or files. While a virus can cause various types of damage to a computer, it does not typically install a "backdoor" internet connection.

Option C) Worm - This option is incorrect. A worm is a type of malicious software that can replicate itself and spread across networks without requiring user interaction. While a worm can cause significant harm by consuming network bandwidth and disrupting systems, it does not typically install a "backdoor" internet connection.

Option D) Adware - This option is incorrect. Adware is a type of software that displays unwanted advertisements on a user's computer. While adware can be annoying and intrusive, it does not typically install a "backdoor" internet connection.

The correct answer is Option A) Trojan. This option is correct because a Trojan is most likely to install a "backdoor" internet connection, allowing unauthorized access to a user's computer.

To answer this question, you need to understand that hackers often use specialized operating systems that are designed for penetration testing and ethical hacking. These operating systems come pre-installed with a wide range of security tools and utilities that can be used for testing the security of computer systems.

Let's go through each option to understand why it is correct or incorrect:

Option A) Solaris - Solaris is a Unix-based operating system developed by Oracle. While it is a popular operating system in enterprise environments, it is not specifically developed for hacking purposes. Therefore, this option is incorrect.

Option B) Ubuntu - Ubuntu is a popular Linux distribution that is widely used for general computing purposes. While it is possible to install hacking tools and utilities on Ubuntu, it is not specifically developed for hacking purposes. Therefore, this option is incorrect.

Option C) BackTrack - BackTrack, now known as Kali Linux, is a Linux distribution specifically developed for penetration testing and ethical hacking. It comes pre-installed with a wide range of security tools and utilities, making it a popular choice among hackers. Therefore, this option is correct.

Option D) Windows - Windows is a widely used operating system developed by Microsoft. While it is possible to install hacking tools and utilities on Windows, it is not specifically developed for hacking purposes. Therefore, this option is incorrect.

The correct answer is Option C) BackTrack. This option is correct because BackTrack, now known as Kali Linux, is a specialized operating system developed for penetration testing and ethical hacking.

To answer this question, you need to understand the concept of DNS spoofing.

Option A) IP Spoofed - This option is incorrect because IP spoofing involves disguising the source IP address in a packet to hide the identity of the sender. It is not relevant to the scenario described in the question.

Option B) DNS Spoofed - This option is correct. DNS spoofing, also known as DNS cache poisoning, occurs when the DNS (Domain Name System) records are manipulated to redirect traffic from a legitimate website to a malicious or unauthorized website. In the given scenario, the redirection from www.google.com to www.yahoo.com indicates that the DNS records have been tampered with, resulting in the website being redirected.

Option C) Email Spoofed - This option is incorrect because email spoofing refers to the creation of email messages with a forged sender address to deceive the recipient. It is not relevant to the scenario described in the question.

Option D) Packet Spoofed - This option is incorrect because packet spoofing involves forging the source or destination address in an IP packet to deceive network devices. It is not relevant to the scenario described in the question.

The correct answer is B) DNS Spoofed. This option is correct because the redirection from www.google.com to www.yahoo.com indicates that the DNS records have been manipulated or spoofed.

To answer this question, you need to understand the concept of how hackers gain entry to a network by pretending to be at a legitimate computer.

Option A) Phishing - This option is incorrect because phishing is a method where hackers trick individuals into revealing sensitive information, such as usernames, passwords, or credit card details, by pretending to be a trustworthy entity through email, phone calls, or fake websites.

Option B) Forging - This option is incorrect because forging typically refers to creating counterfeit documents or imitating someone's signature. It is not directly related to hackers gaining entry to a network by pretending to be at a legitimate computer.

Option C) ID Theft - This option is incorrect because identity theft involves stealing someone's personal information, such as their name, Social Security number, or credit card details, for fraudulent purposes. It does not directly relate to hackers pretending to be at a legitimate computer to gain entry to a network.

Option D) IP Spoofing - This option is correct because IP spoofing is a technique used by hackers to forge or fake the source IP address of a packet to make it appear as if it is coming from a legitimate computer on the network. By doing this, hackers can bypass network security measures and gain unauthorized access to the network.

The correct answer is D) IP Spoofing. This option is correct because it accurately describes the method that hackers use to gain entry to a network by pretending to be at a legitimate computer.
