RFID (Radio Frequency Identification) is a short-range wireless communication technology that uses radio waves to identify and track objects. RFID tags are attached to objects and RFID readers scan the tags to obtain the information stored in them. RFID is commonly used for access control, inventory management, and identification3.

TCP Timestamps is the vulnerability with a severity score of 8.0. This can be verified by performing a vulnerability assessment of the web server located at IP address 20.20.10.26 using the OpenVAS vulnerability scanner, available with the Parrot Security machine, with credentials admin/password. To perform the vulnerability assessment, one can follow these steps:

Launch the Parrot Security machine and open a terminal.

Enter the command sudo openvas-start to start the OpenVAS service and wait for a few minutes until it is ready.

Open a web browser and navigate to https://127.0.0.1:9392 to access the OpenVAS web interface.

Enter the credentials admin/password to log in to OpenVAS.

Click on Scans -> Tasks from the left menu and then click on the blue icon with a star to create a new task.

Enter a name and a comment for the task, such as “Web Server Scan”.

Select “Full and fast” as the scan config from the drop-down menu.

Click on the icon with a star next to Target to create a new target.

Enter a name and a comment for the target, such as “Web Server”.

Enter 20.20.10.26 as the host in the text box and click on Save.

Select “Web Server” as the target from the drop-down menu and click on Save.

Click on the green icon with a play button next to the task name to start the scan and wait for it to finish.

Click on the task name to view the scan report and click on Results from the left menu to see the list of vulnerabilities found.

Sort the list by Severity in descending order and look for the vulnerability with a severity score of 8.0. The screenshot below shows an example of performing these steps: The vulnerability with a severity score of 8.0 is TCP Timestamps, which is an option in TCP packets that can be used to measure round-trip time and improve performance, but it can also reveal information about the system’s uptime, clock skew, or TCP sequence numbers, which can be used by attackers to launch various attacks, such as idle scanning, OS fingerprinting, or TCP hijacking1. The vulnerability report provides more details about this vulnerability, such as its description, impact, solution, references, and CVSS score2.

Incident impact assessment is the post-incident activity performed by Cairo in this scenario. Incident impact assessment is a post-incident activity that involves determining all types of losses caused by the incident by identifying and evaluating all affected devices, networks, applications, and software. Incident impact assessment can include measuring financial losses, reputational damages, operational disruptions, legal liabilities, or regulatory penalties1. References: Incident Impact Assessment

Risk avoidance is the risk treatment option suggested by the risk management team in this scenario. Risk avoidance is a risk treatment option that involves eliminating the identified risk by changing the scope, requirements, or objectives of the project or activity. Risk avoidance can be used when the risk cannot be prevented using security controls or when the risk outweighs the benefits2. References: Risk Avoidance

Mitigating security risks associated with OS virtualization involves a comprehensive approach. Here’s a breakdown of the steps:

Implement Least Privilege Access Control for Users Managing VMs:

Limit access to only those users who need it.

Ensure that users have only the permissions necessary to perform their tasks.

Regularly Patch and Update the Hypervisor Software for Security Fixes:

Keep the hypervisor and virtualization software up-to-date to protect against known vulnerabilities.

Regular patching minimizes the risk of exploitation.

Disable Security Features on Virtual Machines to Improve Performance:

Note: This is actually a security risk. The correct approach is toenable and configure security featuresto protect VMs, despite the potential minor impact on performance.

Comprehensive Approach:

A holistic security strategy includes enforcing least privilege, maintaining updated systems, and enabling security features on VMs to protect against a wide range of threats.

Definition of Evil Twin Attack:

An Evil Twin Attack involves setting up a rogue access point that mimics a legitimate Wi-Fi network. Unsuspecting users connect to this rogue AP, allowing the attacker to intercept and capture network traffic.

Definition of Zero-Day Vulnerability:

A zero-day vulnerability is a flaw in software that is unknown to the vendor and thus has no patch available. Exploiting such a vulnerability allows attackers to infiltrate systems without detection.

GDPR Overview:

The General Data Protection Regulation (GDPR) is a regulation in EU law on data protection and privacy for individuals within the European Union and the European Economic Area.

 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.

Select All hosts in my subnet option and click on OK button.

Wait for the hosts to appear in the list.

Right-click on 20.20.10.26 (FTP server) and select Resolve Host Name option.

Note down the host name as ftpserver.movieabc.com

Click on Passwords tab.

Click on + icon to add items to list.

Select Network Passwords option.

Select FTP option from Protocol drop-down list.

Click on OK button.

Wait for the FTP credentials to appear in the list.

Note down the username as hat and the password as red

Open a web browser and type ftp://hat:red@ftpserver.movieabc.com

Press Enter key to access the FTP server using the stolen credentials.

Navigate to flag.txt file and open it.

Read the file content.
