Steps of the Cyber Kill Chain®

Developed to identify and prevent cyber intrusions.

The steps of the Cyber Kill Chain help analysts understand the techniques, tools, and procedures of threat actors.

The threat actor gains more access to the target as they progress through the steps.

The goal is to stop them as early as possible to lessen the damage done.

5

The Cyber Kill Chain Reconnaissance

Reconnaissance is when the threat actor performs research, gathers intelligence, and selects targets.

Organizations may provide information on websites, public-facing network devices, in news articles, conference proceedings, and social media outlets.

6

The Cyber Kill Chain Weaponization

Weaponization uses the vulnerability information gathered in the reconnaissance step to identify and develop a weapon against specific targeted systems in the organization.

7

The Cyber Kill Chain Delivery

Delivery is when the threat actor delivers the developed weapon using either a website, a removable USB media, or an email attachment.

8

The Cyber Kill Chain Exploitation

Exploitation is when the threat actor triggers the weapon and executes it to compromise the vulnerability and gain control of the target.

9

The Cyber Kill Chain Installation

Installation is when the threat actor establishes a back door into the system to allow for continued access to the target.

10

The Cyber Kill Chain Command and Control

Command & Control (CnC or C2) is when an outside server channel is used by the threat actor to manipulate a target by issuing commands to the software that they installed on the target.

11

The Cyber Kill Chain Actions on Objectives

Actions on Objectives is the final step of the kill chain and is when the attacker achieves attack objective.

Can be used for data theft, performing a DDoS attack, or using the compromised network to create and send spam.

Threat actor is deeply rooted in the systems of the organization and may be extremely difficult to remove from the network.

Oh, we have Registry data, we can detect that
