The Seven Stages of the Cyber Kill Chain

Given trucking’s critical role in the supply chain, it’s no surprise the industry is an attractive target for cyber criminals. Understanding the Cyber Kill Chain and knowing its seven stages gives fleets an advantage in heading off cyberattacks.

The term “Cyber Kill Chain” was coined in 2011 by Lockheed Martin, the American defense, information security and technology company. It refers to the set of steps leading up to a successful cyberattack. In trucking, it can involve things like phishing emails or vulnerabilities in outdated software allowing an attacker to target logistics data, fleet management software or even vehicle control systems. And the results can be detrimental: disruption of deliveries, data breaches, financial losses or even potential accidents on the road.

Lockheed Martin developed its Cyber Kill Chain as a framework made up of seven sequential stages with the idea that if an organization knows how to identify a potential threat at any phase in the process, it has a better chance of breaking the chain of attack and stopping an attacker from successfully infiltrating and compromising its security.

Familiarity with the Cyber Kill Chain enables fleets and other organizations to proactively identify and block attacks at each stage. It can also aid in determining what areas need protecting.

Stage 1: Reconnaissance This phase involves compiling information about the target company or system. The attacker collects data about potential vulnerabilities, company personnel, technologies and network infrastructure.

Stage 2: Weaponization The attacker then creates malicious software, such as viruses or Trojans. It then pairs them with an exploit – a program or piece of code designed to use a weakness in the system. This allows the attacker to take advantage of a security flaw or vulnerability identified in Stage 1 to gain unauthorized access or perform harmful actions.

Stage 3: Delivery In this stage, the attacker delivers the weaponized malware to the target. Common methods of delivery include phishing emails, malicious attachments or software vulnerability abuses.

Stage 4: Exploitation This step occurs when the malware activates to compromise or cause harm to the victim’s system.

Stage 5: Installation In this phase, the attacker installs a backdoor or other mechanism to work around a system’s security measures. This gives the attacker continued access to the compromised system.

Stage 6: Command and Control The attacker establishes a communication channel with the compromised system to send commands and receive data. This phase enables remote control over the target system.

Stage 7: Actions on Objectives Mission is accomplished when attackers succeed in stealing data, destroying systems or otherwise achieving what they set out to do. It is at this stage when users may realize something is wrong.

In conjunction with the Cyber Kill Chain, there are a variety of ways for fleets to mitigate cyber risks. These include:

• Educating employees about phishing scams and best practices for cybersecurity hygiene
• Isolating critical systems from the public internet to limit potential access to cyber criminals
• Promptly addressing vulnerabilities in software and systems
• Implementing security tools to monitor network activity and identify suspicious behavior
• Creating a response plan to cyber incidents that includes data backup and recovery procedures

By learning to identify the stages of the Cyber Kill Chain and understanding ways to strengthen defenses, monitor systems and mitigate risks at each step, an organization can significantly reduce the risk of being victimized by a cyberattack.
