CompTIA Updated PT0-002 Exam Questions and Answers by elowen

The best option for the penetration tester to maintain root-level persistence on this server during the test is to add a new user with ID 0 to the /etc/passwd file. This will allow the penetration tester to use the same user account as the other user, but with root privileges, meaning that it won’t disrupt the other user’s work. This can be done by adding a new line with the username and the numerical user ID 0 to the /etc/passwd file. For example, if the username for the other user is “johndoe”, the line to add would be “johndoe:x:0:0:John Doe:/root:/bin/bash”. After the user is added, the penetration tester can use the “su” command to switch to the new user and gain root privileges.

1: Null session enumeration

Weak SMB file permissions

Fragmentation attack

2: nmap

3: #!/usr/bin/python

export $PORTS = 21,22

for $PORT in $PORTS:

try:

s.connect((ip, port))

print(“%s:%s – OPEN” % (ip, port))

except socket.timeout

print(“%:%s – TIMEOUT” % (ip, port))

except socket.error as e:

print(“%:%s – CLOSED” % (ip, port))

finally

s.close()

port_scan(sys.argv[1], ports)

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.
