The Lockheed Cyber Kill Chain is a framework that describes the seven stages of a cyberattack. It was developed by Lockheed Martin in 2011 and has since become a widely accepted model for understanding how cyberattacks are carried out. The seven stages of the Lockheed Cyber Kill Chain are:
- Reconnaissance: The attacker gathers information about the target, such as its network infrastructure, operating systems, and applications.
- Weaponization: The attacker develops or acquires malware or other tools that will be used to exploit vulnerabilities in the target’s systems.
- Delivery: The attacker delivers the malware or other tools to the target, typically through phishing emails, malicious websites, or USB drives.
- Exploitation: The attacker exploits vulnerabilities in the target’s systems to gain access to the network and its data.
- Installation: The attacker installs malware or other tools on the target’s systems to maintain access and control over the network.
- Command and control: The attacker establishes a command and control channel to communicate with the malware or other tools installed on the target’s systems.
- Actions on objectives: The attacker uses the malware or other tools to achieve their objectives, such as stealing data, disrupting operations, or launching further attacks.
The Lockheed Cyber Kill Chain is a valuable tool for understanding how cyberattacks are carried out and for developing strategies to defend against them. By understanding the different stages of the kill chain, organizations can better prepare for and respond to cyberattacks.
In addition to its importance for cybersecurity, the Lockheed Cyber Kill Chain has also been used in other fields, such as law enforcement and intelligence gathering. It provides a structured and repeatable way to investigate cybercrimes and to track the activities of cybercriminals.

3. Delivery
In the context of the Lockheed Cyber Kill Chain, Delivery encompasses the crucial stage where attackers distribute the malicious tools they have developed or acquired to the target’s systems. This step plays a pivotal role in advancing the attack and setting the stage for subsequent stages.
-
Delivery Methods
Attackers employ various methods to deliver their tools to the target’s systems, including:- Phishing emails: Deceptive emails designed to trick recipients into clicking on malicious links or opening attachments that contain malware.
- Drive-by downloads: Exploiting vulnerabilities in web browsers or plugins to automatically download malware onto a target’s computer when they visit a compromised website.
- Malicious USB drives: Leaving infected USB drives in public places or sending them to targets via mail, hoping they will be inserted into a computer and execute the malware.
-
Target Selection
Attackers carefully select their targets for delivery based on factors such as the potential for valuable data, the vulnerability of the target’s systems, and the likelihood of successful exploitation. -
Countermeasures
Organizations can implement several measures to protect against delivery attacks:- Educating employees about phishing and social engineering techniques.
- Using firewalls and intrusion detection systems to block malicious traffic.
- Keeping software and operating systems up to date with the latest security patches.
- Implementing strong password policies and multi-factor authentication.
The Delivery stage of the Lockheed Cyber Kill Chain underscores the critical need for organizations to implement robust security measures to prevent attackers from successfully delivering their malicious tools and gaining a foothold in their systems.
4. Exploitation
In the context of the Lockheed Cyber Kill Chain, Exploitation represents a critical stage where attackers leverage identified vulnerabilities to gain unauthorized access to the target’s systems. This stage is pivotal in advancing the attack as it allows attackers to establish a foothold within the target’s network and execute subsequent malicious activities.
Exploitation techniques vary depending on the specific vulnerabilities present in the target’s systems. Common methods include exploiting software bugs, misconfigurations, or weak passwords to bypass security controls and gain elevated privileges. Attackers may also use specialized tools or exploit frameworks to automate the exploitation process and increase their chances of success.
The importance of Exploitation as a component of the Lockheed Cyber Kill Chain lies in its role as a gateway to further malicious activities. Once attackers successfully exploit a vulnerability, they can gain access to sensitive data, disrupt system operations, or launch additional attacks from within the compromised network. This can have severe consequences for the target organization, leading to financial losses, reputational damage, or even operational shutdown.
Understanding the significance of Exploitation within the Lockheed Cyber Kill Chain is crucial for organizations to develop effective defense strategies. By implementing robust security measures, patching vulnerabilities promptly, and conducting regular security assessments, organizations can minimize the risk of successful exploitation attempts and protect their systems from unauthorized access.
5. Installation
In the realm of cybersecurity, the Installation stage of the Lockheed Cyber Kill Chain assumes great significance. It represents the phase where attackers establish a persistent presence within the target’s systems, solidifying their foothold and creating a gateway for further malicious activities.
The importance of Installation stems from its role as a foundation for sustained access and control over the compromised systems. Once attackers successfully exploit a vulnerability and gain initial access, they seek to install malware, backdoors, or other malicious tools to maintain their presence and facilitate ongoing operations.
Real-life examples illustrate the devastating consequences of successful Installation. In 2017, the infamous NotPetya cyberattack leveraged EternalBlue, an exploit targeting Microsoft Windows systems, to spread rapidly across networks. Once installed, NotPetya encrypted critical data, rendering systems unusable and causing billions of dollars in damages.
Understanding the significance of Installation within the Lockheed Cyber Kill Chain is paramount for organizations to bolster their defenses. Implementing robust endpoint security measures, deploying intrusion detection and prevention systems, and promoting cybersecurity awareness among employees can help mitigate the risk of successful Installations.
6. Command and Control
In the context of the Lockheed Cyber Kill Chain, Command and Control (C2) holds significant importance as it enables attackers to maintain persistent communication with the tools installed on the target’s systems. This stage plays a crucial role in sustaining the attacker’s presence, facilitating data exfiltration, and executing further malicious activities.
-
Establishing Communication Channels
C2 involves establishing covert communication channels between the attacker and the compromised systems. These channels allow attackers to send commands, receive data, and maintain control over the infected systems remotely. -
Data Exfiltration and Exploitation
Once C2 is established, attackers can exfiltrate sensitive data, such as financial information, intellectual property, or personally identifiable information, from the target’s systems. This data can be sold on the dark web or used for further exploitation. -
Lateral Movement and Persistence
C2 capabilities enable attackers to move laterally within the target’s network, compromising additional systems and establishing persistence. This allows them to maintain a foothold in the network, even if some infected systems are detected and removed. -
Remote Control and Execution
Through C2, attackers can remotely control the compromised systems, execute commands, and deploy additional malware or tools to escalate their privileges or launch further attacks.
Understanding the significance of C2 within the Lockheed Cyber Kill Chain is essential for organizations to develop effective defense strategies. Implementing network monitoring tools, intrusion detection systems, and endpoint security solutions can help detect and disrupt C2 communications, mitigating the risks associated with this stage.
