Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.
Identify the type of cipher employed by Kevin in the above scenario.
Correct Answer: A
A transposition cipher rearranges characters or bits of plaintext to produce ciphertext. In Kevin’s scenario, he used an algorithm that rearranges the same characters to create the ciphertext. This aligns with the characteristics of a transposition cipher, where the order of characters is altered without changing their identity.

Sandra, a hacker, targeted Johana, a software professional, to steal her banking details. She started sending frequent, random pop-up messages
with malicious links to her social media page. Johana accidentally clicked on a link, causing a malicious program to get installed in her system.
Subsequently, when Johana attempted to access her banking website, the URL directed her to a malicious website controlled by Sandra.
Johana entered her banking credentials on the fake website, which Sandra then captured.
Identify the type of attack performed by Sandra on Johana.
Correct Answer: B
The attack performed by Sandra on Johana is known as pharming . Pharming is a type of social engineering cyberattack where criminals redirect internet users trying to reach a specific website to a different, fake site. These “spoofed” sites aim to capture a victim’s personally identifiable information (PII) and login credentials, such as passwords, social security numbers, and account numbers. In Johana’s case, Sandra manipulated the URL to direct her to a malicious website where she entered her banking credentials, which Sandra then captured 1 .

Which of the following MAC forensic data components saves file information and related events using a token
with a binary structure?
Correct Answer: D
In the context of MAC (Mandatory Access Control) forensics, the Basic Security Module (BSM) is known to save file information and related events using a token with a binary structure. BSM is part of the auditing system that records security-related events and data. Each BSM audit record is composed of one or more tokens, where each token has a specific type identifier followed by data relevant to that token type. This structure allows for a detailed and organized way to store and retrieve event data, which is crucial for forensic analysis.
References : The explanation provided is based on general knowledge of MAC forensics and the role of BSM in such environments. For detailed information, it is recommended to refer to the EC-Council Certified Security Specialist (E|CSS) study materials and official documentation.
Clark, a security professional, was instructed to monitor and continue the backup functions without interrupting the system or application services. In this process,
Clark implemented a backup mechanism that dynamically backups the data even If the system or application resources are being used.
Which of the following types of backup mechanisms has Clark implemented in the above scenario?
Correct Answer: C
The scenario describes Paola tampering with new hardware while it was in transit to make it vulnerable to attacks. This type of attack is known as a distribution attack . Distribution attacks involve the interception and manipulation of products during their delivery process 1 . By accessing and tampering with the hardware before it reaches its final destination, the attacker can introduce vulnerabilities or backdoors that can be exploited later.
This method is distinct from an insider attack, which would involve someone within the organization facilitating the breach. A passive attack refers to monitoring and capturing data without altering the system, and an active attack involves direct engagement with the system to disrupt or manipulate operations. Since Paola’s actions involve tampering with hardware during distribution, the correct classification is a distribution attack.
Below is an extracted Apache error log entry.
"(Wed Aug 28 13:35:38.878945 2020] (core:error] (pid 12356:tid 8689896234] (client 10.0.0.8] File not found: /images/folder/pic.jpg"
Identify the element in the Apache error log entry above that represents the IP address from which the request was made.
Correct Answer: A
Certainly! Let’s analyze the Apache error log entry to identify the IP address:
The IP address from which the request was made is 10.0.0.8 (option A).
This address appears in the log entry as follows:
(client 10.0.0.8] File not found: /images/folder/pic.jpg"
