질문 179
A penetration tester analyzed a web-application log file and discovered an input that was sent to the company’s web application. The input contains a string that says “WAITFOR.” Which of the following attacks is being attempted?

SQL 주입

HTML injection

Remote command injection

DLL injection

설명
WAITFOR can be used in a type of SQL injection attack known as time delay SQL injection or blind SQL injection34. This attack works on the basis that true or false queries can be answered by the amount of time a request takes to complete. For example, an attacker can inject a WAITFOR command with a delay argument into an input field of a web application that uses SQL Server as its database. If the query returns true, then the web application will pause for the specified period of time before responding; if the query returns false, then the web application will respond immediately. By observing the response time, the attacker can infer information about the database structure and data1.
Based on this information, one possible answer to your question is A.
SQL injection, because it is an attack that exploits a vulnerability in a web application that allows an attacker to execute arbitrary SQL commands on the database server.

질문 180
Which of the following would assist a penetration tester the MOST when evaluating the susceptibility of top-level executives to social engineering attacks?

Scraping social media for personal details

Registering domain names that are similar to the target company’s

Identifying technical contacts at the company

Crawling the company’s website for company information

설명
Scraping social media for personal details can help a penetration tester craft personalized and convincing social engineering attacks against top-level executives, who may share sensitive or confidential information on their profiles. Registering domain names that are similar to the target company’s can be used for phishing or typosquatting attacks, but not specifically against executives. Identifying technical contacts at the company can help with reconnaissance, but not with social engineering. Crawling the company’s website for company information can provide general background knowledge, but not specific details about executives.

질문 181
A penetration tester will be performing a vulnerability scan as part of the penetration test on a client’s website.
The tester plans to run several Nmap scripts that probe for vulnerabilities while avoiding detection. Which of the following Nmap options will the penetration tester MOST likely utilize?

-8 -T0

–script “http*vuln*”

-sn

-O -A

설명
Nmap is a tool that can perform network scanning and enumeration by sending packets to hosts and analyzing their responses. The command Nmap -p 445 -n -T4 –open 172.21.0.0/16 would scan for SMB port 445 over a
/16 network with the following options:
-p 445 specifies the port number to scan.
-n disables DNS resolution, which can speed up the scan by avoiding unnecessary queries.
-T4 sets the timing template to aggressive, which increases the speed of the scan by sending packets faster and waiting less for responses.
-open only shows hosts that have open ports, which can reduce the output and focus on relevant results.
The other commands are not optimal for scanning SMB port 445 over a /16 network when stealth is not a concern and the task is time sensitive.

질문 182
A penetration tester runs a scan against a server and obtains the following output:
21/tcp open ftp Microsoft ftpd

Based on these results, which of the following attacks is MOST likely to succeed?

A birthday attack on 64-bit ciphers (Sweet32)

An attack that breaks RC4 encryption

An attack on a session ticket extension (Ticketbleed)

A Heartbleed attack

질문 185
Penetration tester who was exclusively authorized to conduct a physical assessment noticed there were no cameras pointed at the dumpster for company. The penetration tester returned at night and collected garbage that contained receipts for recently purchased networking :. The models of equipment purchased are vulnerable to attack. Which of the following is the most likely next step for the penetration?

Alert the target company of the discovered information.

Verify the discovered information is correct with the manufacturer.

Scan the equipment and verify the findings.

Return to the dumpster for more information.

설명
The most likely next step for the penetration tester is to scan the equipment and verify the findings, which is a process of using tools or techniques to probe or test the target equipment for vulnerabilities or weaknesses that can be exploited. Scanning and verifying the findings can help the penetration tester confirm that the models of equipment purchased are vulnerable to attack, and identify the specific vulnerabilities or exploits that affect them. Scanning and verifying the findings can also help the penetration tester prepare for the next steps of the assessment, such as exploiting or reporting the vulnerabilities. Scanning and verifying the findings can be done by using tools such as Nmap, which can scan hosts and networks for ports, services, versions, OS, or other information1, or Metasploit, which can exploit hosts and networks using various payloads or modules2. The other options are not likely next steps for the penetration tester. Alerting the target company of the discovered information is not a next step, but rather a final step, that involves reporting the findings and recommendations to the client after completing the assessment. Verifying the discovered information with the manufacturer is not a next step, as it may not provide accurate or reliable information about the vulnerabilities or exploits that affect the equipment, and it may also alert the manufacturer or the client of the assessment. Returning to the dumpster for more information is not a next step, as it may not yield any more useful or relevant information than what was already collected from the receipts.

질문 186
A penetration tester who is conducting a vulnerability assessment discovers that ICMP is disabled on a network segment. Which of the following could be used for a denial-of-service attack on the network segment?

Smurf

Ping flood

Fraggle

Ping of death

설명
Fraggle attack is same as a Smurf attack but rather than ICMP, UDP protocol is used. The prevention of these attacks is almost identical to Fraggle attack.

질문 187
During enumeration, a red team discovered that an external web server was frequented by employees. After compromising the server, which of the following attacks would best support ————company systems?

Aside-channel attack

A command injection attack

A watering-hole attack

A cross-site scripting attack

설명
The best attack that would support compromising company systems after compromising an external web server frequented by employees is a watering-hole attack, which is an attack that involves compromising a website that is visited by a specific group of users, such as employees of a target company, and injecting malicious code or content into the website that can infect or exploit the users’ devices when they visit the website. A watering-hole attack can allow an attacker to compromise company systems by targeting their employees who frequent the external web server, and taking advantage of their trust or habit of visiting the website. A watering-hole attack can be performed by using tools such as BeEF, which is a tool that can hook web browsers and execute commands on them2. The other options are not likely attacks that would support compromising company systems after compromising an external web server frequented by employees. A side-channel attack is an attack that involves exploiting physical characteristics or implementation flaws of a system or device, such as power consumption, electromagnetic radiation, timing, or sound, to extract sensitive information or bypass security mechanisms. A command injection attack is an attack that exploits a vulnerability in a system or application that allows an attacker to execute arbitrary commands on the underlying OS or shell. A cross-site scripting attack is an attack that exploits a vulnerability in a web application that allows an attacker to inject malicious scripts into web pages that are viewed by other users.
