Cyber Kill Chain

The Cyber Kill Chain is a model that was developed by Lockheed Martin, a major aerospace, military support, and security company, to understand and prevent cyber intrusions in various networks and systems. It serves as a framework for breaking down the stages of a cyber attack, making it easier for security professionals to identify, mitigate, and prevent threats.

The concept is based on a military model, where the term “kill chain” represents a series of steps needed to successfully target and engage an adversary. In the context of cybersecurity, the model breaks down the stages of a cyber attack into seven distinct phases:

  • Reconnaissance: This initial phase involves gathering intelligence on the target, which may include researching public databases, performing network scans, or social engineering techniques.
  • Weaponization: In this stage, the attacker creates a weapon – such as a malware, virus, or exploit – and packages it with a delivery mechanism that can infiltrate the target’s system.
  • Delivery: The attacker selects and deploys the delivery method to transmit the weapon to the target. Common methods include email attachments, malicious URLs, or infected software updates.
  • Exploitation: This is the phase where the weapon is activated, taking advantage of vulnerabilities in the target’s systems or applications to execute the attacker’s code.
  • Installation: Once the exploit is successful, the attacker installs the malware on the victim’s system, setting the stage for further attacks or data exfiltration.
  • Command and Control (C2): The attacker establishes a communication channel with the infected system, allowing them to remotely control the malware and conduct further actions.
  • Actions on Objectives: In this final phase, the attacker achieves their goal, which may involve stealing sensitive data, compromising systems, or disrupting services.

Understanding and analyzing the Cyber Kill Chain helps organizations and individuals take a more proactive approach to cybersecurity. By recognizing the signs of an attack at each stage, appropriate countermeasures can be employed to either prevent or minimize the damage from the attack.

By staying informed and diligently employing security best practices, you can effectively protect your digital assets and contribute to a safer cyberspace.
