 hat@red is the FTP credential that was stolen using Cain and Abel in the above scenario. FTP (File Transfer Protocol) is a protocol that allows transferring files between a client and a server over a network. FTP requires a username and a password to authenticate the client and grant access to the server . Cain and Abel is a tool that can perform various network attacks, such as ARP poisoning, password cracking, sniffing, etc. Cain and Abel can poison the machine and fetch the FTP credentials used by the admin by intercepting and analyzing the network traffic . To validate the credentials that were stolen using Cain and Abel and read the file flag.txt, one has to follow these steps:

Navigate to the Documents folder of Attacker-1 machine.

Double-click on Cain.exe file to launch Cain and Abel tool.

Click on Sniffer tab.

Click on Start/Stop Sniffer icon.

Click on Configure icon.

Select the network adapter and click on OK button.

Click on + icon to add hosts to scan.

 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.
