Jane, an ethical hacker, is testing a target organization's web server and website to identify security loopholes. In this process, she copied the entire website and its content on a local drive to view the complete profile of the site's directory structure, file structure, external links, images, web pages, and so on. This information helps Jane map the website's directories and gain valuable information. What is the attack technique employed by Jane in the above scenario? A. Session hijacking B. Website mirroring C. Website defacement D. Web cache poisoning
Website mirroring
Richard, an attacker, targets an MNC. In this process, he uses a footprinting technique to gather as much information as possible. Using this technique, he gathers domain information such as the target domain name, contact details of its owner, expiry date, and creation date. With this information, he creates a map of the organization's network and misleads domain owners with social engineering to obtain internal details of its network. What type of footprinting technique is employed by Richard? A. VoIP footprinting B. Email footprinting C. Whois footprinting D. VPN footprinting
Whois footprinting

Windows
Attacker Rony installed a rogue access point within an organization's perimeter and attempted to intrude into its internal network. Johnson, a security auditor, identified some unusual traffic in the internal network that is aimed at cracking the authentication mechanism. He immediately turned off the targeted network and tested for any weak and outdated security mechanisms that are open to attack. What is the type of vulnerability assessment performed by Johnson in the above scenario? A. Wireless network assessment B. Application assessment C. Host-based assessment D Distributed assessment
Wireless network assessment

Steven connected his iPhone to a public computer that had been infected by Clark, an attacker. After establishing the connection with the public computer, Steven enabled iTunes Wi-Fi sync on the computer so that the device could continue communication with that computer even after being physically disconnected. Now, Clark gains access to Steven's iPhone through the infected computer and is able to monitor and read all of Steven's activity on the iPhone, even after the device is out of the communication zone. Which of the following attacks is performed by Clark in the above scenario? A. Man-in-the-disk attack B. iOS jailbreaking C. iOS trustjacking D. Exploiting SS7 vulnerability

Jim, a professional hacker, targeted an organization that is operating critical industrial infrastructure. Jim used Nmap to scan open ports and running services on systems connected to the organization's OT network. He used an Nmap command to identify Ethernet/IP devices connected to the Internet and further gathered information such as the vendor name, product code and name, device name, and IP address. Which of the following Nmap commands helped Jim retrieve the required information? A. nmap -Pn -sT --scan-delay 1s --max-parallelism 1 -p < Port List > < Target IP > B. nmap -Pn -sU -p 44818 --script enip-info < Target IP > C. nmap -Pn -sT -p 46824 < Target IP > D. nmap -Pn -sT -p 102 --script s7-info < Target IP >
nmap -Pn -sU -p 44818 --script enip-info < Target IP >
Techno Security Inc. recently hired John as a penetration tester. He was tasked with identifying open ports in the target network and determining whether the ports are online and any firewall rule sets are encountered. John decided to perform a TCP SYN ping scan on the target network. Which of the following Nmap commands must John use to perform the TCP SYN ping scan? A. nmap -sn -PO < target IP address > B. nmap -sn -PS < target IP address > C. nmap -sn -PA < target IP address > D. nmap -sn -PP < target IP address >
