Cyber Security Exploration
Understanding and Addressing Cyber Threats
Scanning Activity
In this section, we’ll perform a basic scanning activity using standard tools such as traceroute, dig, and nslookup. Scanning is a fundamental aspect of cybersecurity that helps identify potential vulnerabilities and map network topologies.
Traceroute Test
Traceroute (or tracert on Microsoft Windows systems) displays information about each “hop” a packet takes from your computer to the remote host.
On Microsoft Windows:
tracert example.com
On Apple MAC OS X and Linux
traceroute example.com
Tracerout result i achieved on Microsoft windows Using CMD for’google.com’.
Dig Test
Dig (on Mac OS X and Linux) and nslookup (on Microsoft Windows) are the primary command-line tools for troubleshooting DNS issues.
dig example.com
Dig Results
- Name Server Records: ns1.example.com, ns2.example.com
- MX Records: mail.example.com
- Time-to-Live (TTL): TTL for records Z seconds
Nslookup Test
nslookup example.com
Nslookup Results i achieved on microsoft windows using CMD for’google.com
sample output view
- IP Address Mapping: X.X.X.X
- Reverse DNS Lookup: example.com
- Domain Information: Registrar: ABC Registrar, Registered on Date
Cross-Tool correlation
Correlating results from all three tools provided a comprehensive view of the network. Interesting findings and potential security concerns include:
- Mismatched Information: Inconsistencies in IP addresses or domain information across tools may indicate a misconfiguration or a potential security risk.
- Unexpected Open Ports: Ports identified by Traceroute that were not corroborated by Dig or Nslookup could be indicative of unauthorized services or devices.
- Domain and IP Address Alignment: Ensure that the domain’s IP address and associated records align correctly to prevent DNS-related attacks.
Mitigations
NOTE: These are general strategies that can help reduce the risk at each stage. Actual mitigations may vary based on specific details. Based on the insights gained from the scanning activity, we’ll discuss potential mitigations to address identified vulnerabilities. Mitigations may include recommendations for securing open ports, implementing firewall rules, or applying patches to eliminate potential points of exploitation. This step is essential for enhancing the overall security posture of the network.

The SolarWinds breach serves as a stark reminder of the sophisticated threats that organizations face in the digital age. The compromise of SolarWinds’ software supply chain highlighted the vulnerability of even well-established and security-conscious entities. The incident underscores the critical importance of robust cybersecurity measures, continuous monitoring, and prompt incident response. As technology evolves, the cybersecurity landscape must adapt to mitigate emerging threats effectively.
Distributed Denial of Service (DDoS)
Introduction to Metasploit: A Powerful Penetration Testing Framework
Metasploit is an open-source penetration testing framework that provides a platform for developing, testing, and executing exploit code against a remote target. Developed in Ruby, Metasploit offers a comprehensive suite of tools for penetration testers, security researchers, and ethical hackers. Its modular architecture, extensive exploit database, and a wide range of supported platforms make it a go-to choice for professionals involved in assessing and fortifying the security of systems.
Launching a DDoS Attack with Metasploit
In this experiment, we’ll explore the process of conducting a Distributed Denial of Service (DDoS) attack using Metasploit. A DDoS attack floods a target server with a massive volume of requests, overwhelming its capacity and making it inaccessible to legitimate users.
. Step1:Setting up Metasploit Ensure Metasploit is installed and accessible. You can open the Metasploit console by entering:
. Step 2: Selecting the Attack Module In the Metasploit console, choose the auxiliary module for a TCP SYN flood attack:
View the available options:
. Step 3: Configuring the Attack Specify the target IP address, for instance, Apple’s website:
Initiate the attack:
Note: If you encounter errors, consider the machine’s compatibility and follow recommended configurations.
. Step 4: Outcome While the experiment may encounter issues, a successful DDoS attack would not significantly impact the target website with only one node generating requests. Additionally, the attacker’s IP might get flagged temporarily.
Conclusion.
This experiment delves into the realm of ethical hacking, specifically exploring the process of setting up a DDoS attack using Metasploit. It underscores the crucial importance of responsible and meticulous practices in cybersecurity, highlighting the need for careful configuration and adherence to recommended guidelines during security testing. The encountered error serves as a valuable lesson, emphasizing the significance of aligning the chosen environment with tool requirements. The experiment also underscores the responsibility that comes with ethical hacking, encouraging practitioners to make informed choices for accurate and reliable results. In essence, this exploration not only provides technical insights but serves as a reminder of the ethical dimensions inherent in cybersecurity, urging practitioners to approach security testing with a holistic and responsible mindset.
Honeypot
Unveiling Winbox Protocal Vulnerabilities: A honeypot Case Study
In this case study, we delve into building a honeypot for the Winbox protocol, a graphical user interface (GUI) application used to manage MikroTik RouterOS devices. The Winbox protocol has been a target for attackers, notably exploited by the infamous Meris botnet for large-scale DDoS attacks.
Winbox Exploits: Reading and Writing System Files
Two vulnerabilities, allowing unauthorized reading and writing of crucial system files, are at the center of our analysis, with a focus on CVE-2018-14847. Attackers exploit this vulnerability to gain unauthorized access.
Exploiting CVE-2018-14847 Step by Step
-
Reading user.dat File:
- Attackers initiate the process by sending an open-file request to read the user.dat file.
- The MikroTik device responds with the file size.
- SYS_CMD set to 4 instructs the device to read the specified bytes from the file.
- The device sends the content of the user.dat file, containing user credentials.
-
SSH Access via “devel” Username:
- Recovered credentials enable attackers to create a file, enabling SSH access with the “devel” username.
- The dissector captures the creation of the devel-login file.
-
Post-Exploitation Actions:
- Once root shell access is acquired, attackers perform actions like enabling a VPN server and configuring scheduled tasks for persistence.
Setting Up a Winbox Honeypot
To mimic real-world scenarios, we deploy a honeypot for the Winbox protocol. Cowrie, acting as an SSH proxy, forwards traffic to the actual honeypot. MikroTik honeypots can be managed and dynamically created using Cowrie.
Monitoring Winbox Protocol Interactions
Capturing interactions between attackers and the victim via the Winbox protocol is essential. While Cowrie manages SSH interactions, we employ pywinbox to log Winbox protocol commands, aiding in understanding attacker actions.
pywinbox: Decoding Winbox Protocol
- plaintext Protocol Management: pywinbox decrypts Winbox packets, providing insights into attacker commands.
- CVE-2018-14847 Exploitation Detection: Logs all commands, acting as a medium interaction honeypot and forwarding traffic for high interaction.
Conclusions
Understanding protocol intricacies is paramount for deploying effective honeypots. Security teams must comprehend specific protocols to configure honeypots accurately, attracting attackers and capturing malicious activity. Legal and ethical considerations are crucial to ensure compliance and prevent unintended harm.
Deploying honeypots provides valuable insights for proactive defense strategies, contributing to a more secure cyber landscape.

Reflections on Cybersecurity in Light of the ‘Energy Crisis’
While not explicitly addressing the energy crisis, the information underscores the importance of considering sustainability in the digital economy. Balancing the benefits of digital transformation with reducing energy consumption becomes crucial, especially in the context of the 2022 worldwide energy crisis.
This dual perspective emphasizes the need for organizations, whether fully digital enterprises or SMEs transitioning to digital, to fortify cybersecurity measures and align strategies with broader sustainability goals.
