Internal Pentest

An internal pentest is a type of penetration test that simulates an attack originating from a source internal to the organization. This could include a malicious employee, contractor, or visitor with access to the network.

The objectives of an internal pentest

An internal pentest helps identify security vulnerabilities that could be exploited by an internal attacker, assess the organization's ability to detect and respond to an internal attack, and provide recommendations for improving the security of the organization.

Identify security vulnerabilities

Security vulnerabilities may be present in the organization's systems, applications, policies and procedures. They can be exploited by an internal attacker to gain unauthorized access to the network, steal data, or cause damage.

Here are some examples of vulnerabilities that can be exploited during an internal pentest:

Configuration flaws

Configuration vulnerabilities can be present in systems, applications and networks. These vulnerabilities can allow an internal attacker to gain unauthorized access to the network, for example by allowing access to unsecured ports or services.

Weak or reused passwords

Weak or reused passwords are a common vulnerability that can be easily exploited by an insider attacker. An internal attacker can gain access to the network by guessing or hacking employee passwords.

Obsolete software

Outdated software may contain known vulnerabilities. These vulnerabilities can be exploited by an internal attacker to gain unauthorized access to the network, for example by allowing the execution of malicious code.

Lack of access control

Lack of access control can allow an insider attacker to access resources they should not have access to. For example, if an insider attacker has access to a workstation, they can access sensitive data that should not be accessible to all employees.

Insufficient employee training

Employees who are not adequately trained in security risks can be a source of vulnerability. An internal attacker can exploit employees' ignorance to gain unauthorized access to the network, for example by tricking them into clicking on a malicious link or opening an infected file.

Assess the organization's ability to detect and respond to an insider attack

An internal pentest can also help assess the organization's ability to detect and respond to an internal attack. This may include evaluating incident detection and response systems (SIEM/SOAR), incident response policies and procedures, and employee training.

He can help identify weaknesses in incident detection and response systems. For example, an insider attacker may be able to disable detection systems or trick them into thinking an attack is not in progress.

An internal pentest can also help identify weaknesses in incident response policies and procedures. For example, an insider attacker may be able to exploit a gap in containment policies to gain access to resources they should not have access to.

Provide recommendations to improve organizational security

An internal pentest can provide recommendations to improve the organization's security. These recommendations may relate to correcting identified vulnerabilities, improving existing security controls, or implementing new controls.

Recommendations from an internal pentest should be implemented quickly to reduce the risk of an attack.

The different types of internal pentests

Internal pentesting can be carried out in different ways, depending on the organization's goals and available resources. The most common types of tests are:

Vulnerability testing

Vulnerability testing is the most common type of internal pentesting. It involves identifying vulnerabilities in the organization's systems and applications. The security expert uses a variety of techniques, such as code analysis, port scanning, and exploit testing, to identify vulnerabilities.

Techniques used include code analysis, port scanning, and exploitation testing.

Operational test

Operational testing is a more advanced type of internal pentesting. It consists of exploiting the vulnerabilities identified during a vulnerability test. The security expert attempts to gain unauthorized access to the network using the vulnerabilities he found.

Techniques used include the use of malicious scripts, account takeover and privilege escalation.

Audit test

Audit testing is a type of internal pentesting that examines the organization's security policies and procedures. The security expert reviews security policies and procedures to identify areas for improvement.

Techniques used include reviewing policies and procedures, interviewing employees, and analyzing logs.

Social engineering test

Social engineering testing is a type of internal pentesting that uses social engineering techniques to deceive employees and gain unauthorized access to the network.

The social engineering test aims to identify employees who may fall into social engineering traps. The techniques used include sending fake emails, using fake websites and making phone calls.

Attack simulation test

Attack simulation testing is a type of internal pentest that simulates a real attack on the organization. The security expert uses the same techniques as a real attacker to gain unauthorized access to the network.

The attack simulation test aims to assess the organization's ability to detect and respond to a real attack.

Choice of internal pentest type

Choosing the type of internal pentest to perform depends on the organization's goals. If the organization wishes to:

  • Identify vulnerabilities in its systems and applications, a vulnerability test is sufficient.
  • To assess the severity of vulnerabilities and the consequences of successful exploitation, exploitation testing is necessary.
  • Identify gaps in its security policies and procedures, an audit test is necessary.
  • To assess the ability of its employees to resist social engineering attacks, a social engineering test is necessary.
  • To assess the organization's ability to detect and respond to a real attack, an attack simulation test is necessary.

Active Directory & Internal Pentest

Active Directory (AD) is a centralized directory service used by Windows systems to store and manage information about users, computers, and other network resources. It is a crucial part of many organizations' IT infrastructure, and compromising it can have serious consequences.

During an internal pentest, the Active Directory is a prime target for attackers because it offers many opportunities for exploitation.

Opportunities for leveraging Active Directory

1. Privileged accounts

Active Directory administrators have extensive rights that can be used to take control of the system.

Attackers can attempt to steal the credentials of these accounts or exploit vulnerabilities to elevate them.

Examples of attacks:

  • Brute force attack.
  • Password spraying attack.
  • Phishing attack.
  • Golden Ticket Attack.
  • Pass-the-Hash attack.

2. AD service vulnerabilities

The AD service itself may be vulnerable to attacks, such as:

  • NTLM password replay attack.
  • Kerberos service replay attack.
  • DCSync attack.
  • Silver Ticket Attack.

3. Bad configurations

Misconfiguration of AD can create security vulnerabilities that attackers can exploit.

Examples of bad configurations:

  • Excessive access rights granted to users.
  • Weak password policies.
  • Security controls not enabled.

Attack Techniques Used by Pentesters

Here are some of the techniques pentesters can use to attack Active Directory:

Information retrieval

Using tools like Nmap, Bloodhound, and ldapsearch to collect information about users, computers, and AD groups.

Querying AD servers and domain controllers to obtain sensitive information.

Brute force attacks

Using tools like Hydra and John the Ripper to try to guess passwords for user or administrator accounts.

LDAP injection attacks

Injecting malicious code into LDAP queries to gain unauthorized access to the system.

Privilege escalation attacks

Exploitation of vulnerabilities to gain higher access rights on the system.

Using tools like Metasploit and PowerSploit to run exploits and elevate privileges.
