Shawn, a forensic officer, was appointed to investigate a crime scene that had occurred at a coffee shop. As a part of investigation, Shawn collected the mobile device from the victim, which may contain potential evidence to identify the culprits.
Which of the following points must Shawn follow while preserving the digital evidence? (Choose three.)
- A. Do not leave the device as it is if it is ON
- B. Never record the screen display of the device
- C. Turn the device ON if it is OFF
- D. Make sure that the device is charged
Answer: A,C,D
Explanation:
Turn the device ON if it is OFF, do not leave the device as it is if it is ON, and make sure that the device is charged are some of the points that Shawn must follow while preserving the digital evidence in the above scenario. Digital evidence is any information or data stored or transmitted in digital form that can be used in a legal proceeding or investigation. Digital evidence can be found on various devices, such as computers, mobile phones, tablets, etc. Preserving digital evidence is a crucial step in forensic investigation that involves protecting and maintaining the integrity and authenticity of digital evidence from any alteration or damage.
Some of the points that Shawn must follow while preserving digital evidence are:
* Turn the device ON if it is OFF: If the device is OFF, Shawn must turn it ON to prevent any data loss or encryption that may occur when the device is powered off. Shawn must also document any password or PIN required to unlock or access the device.
* Do not leave the device as it is if it is ON: If the device is ON, Shawn must not leave it as it is or use it
* for any purpose other than preserving digital evidence. Shawn must also disable any network connections or communication features on the device, such as Wi-Fi, Bluetooth, cellular data, etc., to prevent any remote access or deletion of data by unauthorized parties.
* Make sure that the device is charged: Shawn must ensure that the device has enough battery power to prevent any data loss or corruption that may occur due to sudden shutdown or low battery. Shawn must also use a write blocker or a Faraday bag to isolate the device from any external interference or signals.
Never record the screen display of the device is not a point that Shawn must follow while preserving digital evidence. On contrary, Shawn should record or photograph the screen display of the device to capture any relevant information or messages that may appear on the screen. Recording or photographing the screen display of the device can also help document any changes or actions performed on the device during preservation.

NEW QUESTION # 70
Kevin, a professional hacker, wants to penetrate CyberTech Inc.'s network. He employed a technique, using which he encoded packets with Unicode characters. The company's IDS cannot recognize the packet, but the target web server can decode them.
What is the technique used by Kevin to evade the IDS system?
- A. Obfuscating
- B. Session splicing
- C. Desynchronization
- D. Urgency flag
Answer: A
Explanation:
Obfuscating is the technique used by Kevin to evade the IDS system in the above scenario. Obfuscating is a technique that involves encoding or modifying packets or data with various methods or characters to make them unreadable or unrecognizable by an IDS (Intrusion Detection System). Obfuscating can be used to bypass or evade an IDS system that relies on signatures or patterns to detect malicious activities. Obfuscating can include encoding packets with Unicode characters, which are characters that can represent various languages and symbols. The IDS system cannot recognize the packet, but the target web server can decode them and execute them normally. Desynchronization is a technique that involves creating discrepancies or inconsistencies between the state of a connection as seen by an IDS system and the state of a connection as seen by the end hosts. Desynchronization can be used to bypass or evade an IDS system that relies on stateful inspection to track and analyze connections. Desynchronization can include sending packets with invalid sequence numbers, which are numbers that indicate the order of packets in a connection. Session splicing is a technique that involves splitting or dividing packets or data into smaller fragments or segmentsto make them harder to detect by an IDS system. Session splicing can be used to bypass or evade an IDS system that relies on packet size or content to detect malicious activities. Session splicing can include sending packets with small MTU (Maximum Transmission Unit) values, which are values that indicate the maximum size of packets that can be transmitted over a network. An urgency flag is a flag in the TCP (Transmission Control Protocol) header that indicates that the data in the packet is urgent and should be processed immediately by the receiver.
An urgency flag is not a technique to evade an IDS system, but it can be used to trigger an IDS system to generate an alert or a response.

- B. 20.20.10.19
- C. 20.20.10.60
- D. 20.20.10.180
Answer: B
Explanation:
20.20.10.19 is the source IP address of the SYN flooding attack in the above scenario. SYN flooding is a type of denial-of-service (DoS) attack that exploits the TCP (Transmission Control Protocol) three-way handshake process to disrupt the network and gain advantage over the network to bypass the firewall. SYN flooding sends a large number of SYN packets with spoofed source IP addresses to a target server, causing it to allocate resources and wait for the corresponding ACK packets that never arrive. This exhausts the server's resources and prevents it from accepting legitimate requests . To determine the source IP address of the SYN flooding attack, one has to follow these steps:
Navigate to the Documents folder of Attacker-1 machine.
Double-click on Synflood.pcapng file to open it with Wireshark.
Click on Statistics menu and select Conversations option.
Click on TCP tab and sort the list by Bytes column in descending order.
Observe the IP address that has sent the most bytes to 20.20.10.26 (target server).
The IP address that has sent the most bytes to 20.20.10.26 is 20.20.10.19 , which is the source IP address of the SYN flooding attack.
