A penetration tester has been tasked with capturing network traffic to identify hosts, services, and sensitive data. The network uses switches, and the penetration tester wants to maximize their ability to capture traffic from multiple devices. Which of the following approaches is the MOST effective for achieving this goal?

Use ARP poisoning to reroute traffic to the penetration tester's device ARP poisoning is an active sniffing technique that works on a switched network by sending spoofed ARP messages, making devices send traffic to the pentester's machine instead of the actual gateway. This allows the pentester to capture traffic from multiple hosts effectively. This is the most suitable method in a switched environment when the goal is to intercept traffic beyond just the host directly connected to the sniffer.

A PenTester is using Python to write a script in preparation for a PenTest. What can the PenTester do to complete the script quickly as well as take advantage of work that others have already completed? (Select three.)

Use modules Use classes Use pre-built libraries The PenTester can use classes which are user-defined prototypes or templates from which PenTesters can create objects and they allow the PenTester to bundle data and functionality together. The PenTester can use modules which are a way for the PenTester to code re-usable functions, variables, and classes that the tester can import into scripts. The PenTester can use pre-built libraries. Importing and using existing modules in libraries can save the PenTester a lot of time because the tester is re-using modules that others have already created.

A penetration tester is assessing a web application hosted on a cloud platform and discovers that the application accepts user input to fetch the content of a URL. After reviewing the code, the tester finds that the input is not properly sanitized. The tester crafts a URL that targets the Instance Metadata Service (IMS) to obtain sensitive information. What is the next step the penetration tester should take after retrieving temporary credentials from the metadata service?

Use the AWS Command Line Interface (CLI) to perform AWS operations based on the permissions of the retrieved credentials. After retrieving temporary credentials from the metadata service, the penetration tester can use tools like the AWS CLI to perform actions in the cloud environment based on the permissions associated with those credentials. For example, they can list resources, access services, or escalate privileges further depending on what the IAM role permits.

A penetration tester is assessing a web application for vulnerabilities. After initial manual testing, the pentester decides to use automated tools to speed up the process. The assessment includes scanning for exposed API keys, examining form fields, and looking for vulnerabilities such as SQL Injection and insecure server configurations.
