Which is a correct description of a stage in the Lockheed Martin kill chain?

The Lockheed Martin Cyber Kill Chain is a framework that outlines the stages of a cyber attack, from initial reconnaissance to achieving the attacker’s objective. It is often referenced in HPE Aruba Networking security documentation to help organizations understand and mitigate threats. The stages are: Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control (C2), and Actions on Objectives.

Option A, "In the weaponization stage, which occurs after malware has been delivered to a system, the malware executes its function," is incorrect. The weaponization stage occurs before delivery, not after. In this stage, the attacker creates a deliverable payload (e.g., combining malware with an exploit). The execution of the malware happens in the exploitation stage, not weaponization.

Option B, "In the exploitation and installation phases, malware creates a backdoor into the infected system for the hacker," is correct. The exploitation phase involves the attacker exploiting a vulnerability (e.g., a software flaw) to execute the malware on the target system. The installation phase follows, where the malware installs itself to establish persistence, often by creating a backdoor (e.g., a remote access tool) to allow the hacker to maintain access to the system. These two phases are often linked in the kill chain as the malware gains a foothold and ensures continued access.

Option C, "In the reconnaissance stage, the hacker assesses the impact of the attack and how much information was exfiltrated," is incorrect. The reconnaissance stage occurs at the beginning of the kill chain, where the attacker gathers information about the target (e.g., network topology, vulnerabilities). Assessing the impact and exfiltration occurs in the Actions on Objectives stage, the final stage of the kill chain.

Option D, "In the delivery stage, malware collects valuable data and delivers or exfiltrates it to the hacker," is incorrect. The delivery stage involves the attacker transmitting the weaponized payload to the target (e.g., via a phishing email). Data collection and exfiltration occur later, in the Actions on Objectives stage, not during delivery.

The HPE Aruba Networking Security Guide states:

"The Lockheed Martin Cyber Kill Chain outlines the stages of a cyber attack. In the exploitation phase, the attacker exploits a vulnerability to execute the malware on the target system. In the installation phase, the malware creates a backdoor or other persistence mechanism, such as a remote access tool, to allow the hacker to maintain access to the infected system for future actions." (Page 18, Cyber Kill Chain Overview Section)

Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:

"The exploitation and installation phases of the Lockheed Martin kill chain involve the malware gaining a foothold on the target system. During exploitation, the malware is executed by exploiting a vulnerability, and during installation, it creates a backdoor to ensure persistent access for the hacker, enabling further stages like command and control."
