Question 1
Single choice

In the field of cryptanalysis, what is meant by a "rubber-hose" attack?

A.

Forcing the targeted keystream through a hardware-accelerated device such as an ASIC.

B.

A backdoor placed into a cryptographic algorithm by its creator.

C.

Extraction of cryptographic secrets through coercion or torture.

D.

Attempting to decrypt ciphertext by making logical assumptions about the contents of the original plaintext.

Question 2
Single choice

When considering how an attacker may exploit a web server, what is web server footprinting?

A.

When an attacker implements a vulnerability scanner to identify weaknesses

B.

When an attacker creates a complete profile of the site's external links and file structures

C.

When an attacker gathers system-level data, including account details and server names

D.

When an attacker uses a brute-force attack to crack a web-server password

Question 3
Single choice

When configuring wireless on his home router, Javik disables SSID broadcast. He leaves authentication
"open" but sets the SSID to a 32-character string of random letters and numbers.

What is an accurate assessment of this scenario from a security perspective?

A.

Since the SSID is required in order to connect, the 32-character string is sufficient to prevent brute-force attacks.

B.

Disabling SSID broadcast prevents 802.11 beacons from being transmitted from the access point, resulting in a valid setup leveraging "security through obscurity".

C.

It is still possible for a hacker to connect to the network after sniffing the SSID from a successful wireless association.

D.

Javik's router is still vulnerable to wireless hacking attempts because the SSID broadcast setting can be enabled using a specially crafted packet sent to the hardware address of the access point.

Question 4
Single choice

what are common files on a web server that can be misconfigured and provide useful Information for a hacker such as verbose error messages?

A.

httpd.conf

B.

administration.config

C.

idq.dll

D.

php.ini

Question 5
Single choice

What is the common name for a vulnerability disclosure program opened by companies In platforms such as HackerOne?

A.

Vulnerability hunting program

B.

Bug bounty program

C.

White-hat hacking program

D.

Ethical hacking program

Question 6
Single choice

An attacker identified that a user and an access point are both compatible with WPA2 and WPA3 encryption. The attacker installed a rogue access point with only WPA2 compatibility in the vicinity and forced the victim to go through the WPA2 four-way handshake to get connected. After the connection was established, the attacker used automated tools to crack WPA2-encrypted messages.

What is the attack performed in the above scenario?

A.

Timing-based attack

B.

Side-channel attack

C.

Downgrade security attack

D.

Cache-based attack

Question 7
Single choice

B.

Packet Sniffers operate on Layer 2 of the OSI model.

C.

Packet Sniffers operate on both Layer 2 & Layer 3 of the OSI model.

D.

Packet Sniffers operate on Layer 3 of the OSI model.

Question 8
Single choice

Ralph, a professional hacker, targeted Jane, who had recently bought new systems for her company. After a few days, Ralph contacted Jane while masquerading as a legitimate customer support executive, informing that her systems need to be serviced for proper functioning and that customer support will send a computer technician. Jane promptly replied positively.

Question 9
Single choice

Leverox Solutions hired Arnold, a security professional, for the threat intelligence process. Arnold collected information about specific threats against the organization. From this information, he retrieved contextual information about security events and incidents that helped him disclose potential risks and gain insight into attacker methodologies. He collected the information from sources such as humans, social media, and chat rooms as well as from events that resulted in cyberattacks. In this process, he also prepared a report that includes identified malicious activities, recommended courses of action, and warnings for emerging attacks.

What is the type of threat intelligence collected by Arnold in the above scenario?

A.

Strategic threat intelligence

B.

Tactical threat intelligence

C.

Operational threat intelligence

D.

Technical threat intelligence
