Question 91

Which of the following lock-picking techniques is faster but less precise, used when speed is prioritized over precision?

A.Plug spinner
B.Bypassing
C.Decoding
D.Raking

Question 92

During a penetration test of a server application, a security consultant found that the application randomly crashed or remained stable after opening several simultaneous connections to the application and always submitting the same packets of data. Which of the following is the best sequence of steps the tester should use to understand and exploit the vulnerability?

A.Attach a remote profiler to the server application. Establish a random number of connections to the server applicat
B.Attach a remote debugger to the server application. Establish a large number of connections to the server applicat
C.Attach a local disassembler to the server application. Establish a single connection to the server application. Send
D.Attach a remote disassembler to the server application. Establish a small number of connections to the server app

Question 93

During the reconnaissance phase, a penetration tester collected the following information from the DNS records:
A-----> www
A-----> host
TXT --> vpn.comptia.org
SPF---> ip =2.2.2.2
Which of the following DNS records should be in place to avoid phishing attacks using spoofing domain techniques?

A.MX
B.SOA
C.DMARC
D.CNAME

Correct Answer: C

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps prevent email spoofing and phishing. It builds on SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to provide a mechanism for email senders and receivers to improve and monitor the protection of the domain from fraudulent email.
Understanding DMARC:
SPF: Defines which IP addresses are allowed to send emails on behalf of a domain.
DKIM: Provides a way to check that an email claiming to come from a specific domain was indeed authorized by the owner of that domain.
DMARC: Uses SPF and DKIM to determine the authenticity of an email and specifies what action to take if the email fails the authentication checks.
Implementing DMARC:
Create a DMARC policy in your DNS records. This policy can specify to reject, quarantine, or take no action on emails that fail SPF or DKIM checks.
Example DMARC record: v=DMARC1; p=reject; rua=mailto:[email protected]; Benefits of DMARC:
Helps to prevent email spoofing and phishing attacks.
Provides visibility into email sources through reports.
Enhances domain reputation by ensuring only legitimate emails are sent from the domain.
DMARC Record Components:
v: Version of DMARC.
p: Policy for handling emails that fail the DMARC check (none, quarantine, reject).
rua: Reporting URI of aggregate reports.
ruf: Reporting URI of forensic reports.
pct: Percentage of messages subjected to filtering.
Real-World Example:
A company sets up a DMARC policy with p=reject to ensure that any emails failing SPF or DKIM checks are rejected outright, significantly reducing the risk of phishing attacks using their domain.
References from Pentesting Literature:
In "Penetration Testing - A Hands-on Introduction to Hacking," DMARC is mentioned as part of email security protocols to prevent phishing.
HTB write-ups often highlight the importance of DMARC in securing email communications and preventing spoofing attacks.

Question 94

A penetration tester who is doing a security assessment discovers that a critical vulnerability is being actively exploited by cybercriminals. Which of the following should the tester do NEXT?

A.Reach out to the primary point of contact
B.Try to take down the attackers
C.Call law enforcement officials immediately
D.Collect the proper evidence and add to the final report

Question 95

A penetration tester is exploring a client's website. The tester performs a curl command and obtains the following:
* Connected to 10.2.11.144 (::1) port 80 (#0)
> GET /readmine.html HTTP/1.1
> Host: 10.2.11.144
> User-Agent: curl/7.67.0
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 200
