Reconnaissance

During the reconnaissance phase of a penetration test, you are examining a target's public-facing web application. You notice that the application returns detailed error messages that include full file paths and database query snippets. Which of the following best describes the primary risk associated with this finding?

During OSINT gathering, you are investigating a target's presence on social media and professional networking sites. Which TWO of the following methods are effective for gathering metadata about employees to facilitate future social engineering attacks?

You are conducting a penetration test for a client and need to enumerate subdomains of example.com to map their external attack surface. During this reconnaissance phase, you decide to use a tool that performs DNS zone transfers. Which of the following is the most appropriate tool to attempt a DNS zone transfer?

You are conducting external reconnaissance against a target that uses a split-horizon DNS configuration. From the public internet, you query the organization's authoritative name server for the A record of vpn.contoso.com and receive NXDOMAIN. However, you have obtained a leaked internal zone file that shows the same hostname resolving to 10.10.10.50. Which technique would best allow you to identify additional internal-only hostnames without sending traffic to the target's internal network?

You are performing a reconnaissance task and need to identify the physical location or ownership of an organization's IP space. Which TWO of the following services are standard for this task?

During the reconnaissance phase, you notice a target is using an older, unpatched version of a popular CMS. What is the most appropriate next step?

You are conducting passive reconnaissance against a target organization and want to identify internet-facing systems and services without sending any packets to the target's own IP space. Which two techniques best satisfy this requirement? (Choose two.)

Why is it important to perform reconnaissance from a non-attributable source during a penetration test?

During a penetration test, you are performing passive reconnaissance against a target organization. You want to gather information about the organization's public-facing infrastructure without directly interacting with their systems. Which two of the following techniques are considered passive reconnaissance? (Choose two.)

You are conducting a penetration test and have gained access to a target's internal network. You want to perform reconnaissance to identify other live hosts and services without using traditional port scanning that might trigger IDS alerts. Which of the following techniques would be most effective for low-noise host discovery on the internal network?

You are analyzing the results of a passive reconnaissance scan using a tool that harvests metadata from files found on a company website. What is the primary security risk associated with this information disclosure?

When mapping a target's network infrastructure, why is it important to use multiple WHOIS and regional internet registry (RIR) databases?

Which of the following describes the purpose of using Google Dorks during the reconnaissance phase of a penetration test?

During a penetration test, you are reviewing the results of a WHOIS query for a target domain. You notice the registrant's email address is privacy-protected, but the technical contact email is a generic address at a third-party hosting company. What is the most likely explanation for this finding, and what should you do next to gather more information about the target's infrastructure?

You are reviewing the scope of an upcoming penetration test and need to identify the organization's mail exchangers and the servers authoritative for its DNS zones using only publicly available records. Which DNS record types should you query to obtain this information directly?

What is the primary benefit of using passive reconnaissance before initiating active scanning?

You are conducting an external penetration test against a client who uses a split-horizon DNS configuration. You want to identify internal hostnames and IP addresses without sending any traffic to the client's internal network. Which of the following techniques would best accomplish this?

You are performing OSINT on a target and have collected a list of employee names from LinkedIn. You want to generate likely corporate email addresses and then verify which ones are valid without sending email to the target's mail servers. Which approach best accomplishes this?

During a reconnaissance project, you use the 'theHarvester' tool against a target. What information is this tool designed to extract?

You are performing passive reconnaissance on a target organization that uses a cloud-based email service. You want to gather information about the organization's email infrastructure and potential phishing targets without alerting the target. Which TWO of the following techniques would be most effective and appropriate for this goal? (Choose two.)

You are tasked with gathering information about a target organization's employees to craft a phishing campaign. Which of the following tools is specifically designed to collect email addresses, subdomains, and hostnames from public sources like search engines and PGP key servers?

You are conducting passive reconnaissance against a target that uses a Web Application Firewall (WAF) and a Content Delivery Network (CDN). You want to discover the origin IP address of the web server to bypass the CDN during later testing. Which technique is most likely to reveal the origin IP without sending any traffic to the target's domain?
