Cybercriminals are constantly looking for new ways to breach corporate system security, which poses a challenge for IT departments, CISOs, and management to continuously monitor and improve their protective measures. Penetration testing plays a key role in this fight, enabling identification and elimination of weak points before hackers do.
The purpose of this article is to present real attack scenarios that can be used during penetration testing, as well as methods for their detection and neutralization. This will help managers, CEOs, heads of IT departments (CIOs), IT department employees, programming and project departments (PMO), and CISOs better understand threats and effectively counteract potential attacks.
What Are Penetration Tests?
Penetration tests, often referred to as pentests, are controlled and planned attacks on computer systems, networks, applications, and other elements of IT infrastructure, aimed at identifying security vulnerabilities. Their main goal is to simulate real hacker actions to understand how they can exploit these weaknesses and what damage they can cause.
The history of penetration testing dates back to the 1960s, when computer defense systems were first tested. Since then, pentest methods and techniques have significantly evolved, adapting to increasingly advanced technologies and increasingly sophisticated attacks.
In the context of organizational security management, penetration tests serve several key functions:
-
Identifying weak points and security vulnerabilities
-
Assessing the effectiveness of current protective measures
-
Practical training for IT and security teams
-
Ensuring compliance with industry regulations and standards

Examples of Real Attack Scenarios
Scenario 1: Attack on Web Applications
Attack Scenario Description
Web applications are often the target of attacks due to their accessibility from the Internet. The most common types of attacks are SQL Injection and Cross-Site Scripting (XSS). In a SQL Injection attack, hackers inject malicious SQL queries into the application’s input field, allowing them to gain unauthorized access to the database. In an XSS attack, malicious JavaScript code is injected into the application, enabling hackers to steal user data or take control of their browsers.
Examples of Real Attacks
One notable example of a SQL Injection attack is the 2014 incident when the database of one of the largest retail chains in the USA was attacked, leading to the leak of data from millions of customers.
Detection Methods
To detect attacks on web applications, various techniques are used, such as vulnerability scanning (e.g., tools like OWASP ZAP or Burp Suite), regular source code audits, and implementation of attack detection and prevention systems (WAF - Web Application Firewall).
Neutralization Strategies
To neutralize attacks on web applications, you can use:
-
Parameterized database queries to prevent SQL Injection
-
Input data validation and sanitization to prevent XSS
-
Regular software updates and patching
-
Implementation of Content Security Policy
Scenario 2: Attack on Internal Network
Attack Scenario Description
Attacks on internal networks, such as Man-in-the-Middle (MitM) or sniffing, involve intercepting and modifying communication between users and servers. In a MitM attack, hackers insert themselves between two communicating parties to intercept, modify, or steal transmitted data. Sniffing involves intercepting unencrypted network traffic, which allows obtaining sensitive information such as passwords or financial data.
Examples of Real Attacks
One example of a MitM attack is the 2011 incident when hackers attacked bank customers, intercepting login data and making unauthorized transactions.
Detection Methods
To detect attacks on internal networks, network traffic analysis tools (e.g., Wireshark), intrusion detection systems (IDS - Intrusion Detection Systems), and monitoring of server and network device logs are used.
Neutralization Strategies
Neutralization of attacks on internal networks includes:
-
Implementing communication encryption protocols (TLS/SSL)
-
Network segmentation to limit the scope of potential attacks
-
Regular audits and network traffic monitoring
-
Employee training on security best practices
Scenario 3: Social Engineering Attack
Attack Scenario Description
Social engineering attacks, such as phishing or pretexting, involve manipulating people to obtain confidential information. In phishing, hackers send fake email messages that look legitimate to convince the victim to reveal login data or perform certain actions. Pretexting involves creating a false story or identity to gain the victim’s trust and obtain needed information.
Examples of Real Attacks
In 2016, a phishing attack occurred on one of the largest technology companies, leading to the disclosure of thousands of employee data and financial losses.
Detection Methods
Detecting social engineering attacks includes email analysis using anti-phishing tools, monitoring suspicious activities, and training employees to recognize suspicious messages and actions.
Neutralization Strategies
Neutralization of social engineering attacks includes:
-
Employee training on cyber hygiene and phishing recognition
-
Implementation of two-factor authentication (2FA)
-
Using anti-phishing tools
-
Monitoring and analysis of access logs
Scenario 4: Attack on Cloud Infrastructure
Attack Scenario Description
Attacks on cloud infrastructure can include unauthorized access to cloud resources, data exfiltration, or Denial of Service (DoS) attacks. Hackers can exploit configuration errors, weak passwords, or vulnerabilities in cloud applications to gain access to organizational data and systems.
Examples of Real Attacks
In 2019, an attack occurred on one of the largest cloud service providers, causing a data leak of millions of users due to system misconfiguration.
Detection Methods
Detecting attacks on cloud infrastructure includes monitoring access logs, using identity and access management (IAM) tools, and implementing attack detection and prevention systems.
Neutralization Strategies
Neutralization of attacks on cloud infrastructure includes:
-
Regular configuration and security audits
-
Implementation of advanced identity and access management (IAM) systems
-
Monitoring and analysis of cloud activity
-
Using cloud data security platforms (CDSP - Cloud Data Security Platforms)
Attack Detection and Neutralization Methods
To effectively detect and neutralize attacks, organizations must use various techniques and tools. Key detection techniques include:
-
Real-time system and network monitoring
-
Log analysis from servers, network devices, and applications
-
Vulnerability scanning using tools such as Nessus or OpenVAS
-
Implementation of attack detection and prevention systems (IDS/IPS)
For threat neutralization, it is worth applying best practices such as:
-
Regular software updates and patching
-
Implementing communication encryption protocols
-
Network segmentation and access restriction based on least privilege principle
-
Employee security training
Examples of applying these techniques in real attack scenarios show how important a comprehensive approach to IT security management is. Preventive actions and proactive monitoring can significantly reduce the risk of successful attacks on the organization.
Role of the IT Security Team
The IT security team plays a key role in protecting the organization from cyber threats. Its main tasks include risk identification and assessment, implementing protective measures, and responding to incidents. The competencies and skills required to effectively conduct penetration tests include knowledge of various technologies, the ability to analyze and solve problems, and the ability to cooperate with other departments in the organization.
Examples of cooperation between the IT security team and other departments include:
-
Cooperation with the IT department in implementing security
