It’s no secret that the threat landscape is continually evolving, cyber attackers are getting smarter, making their methods increasingly sophisticated. Understanding the steps these attackers take – commonly referred to as the “Cyber Attack Lifecycle” or “Cyber Kill Chain” can help organisations take proactive measures to identify, remediate, and recover from cyber threats.

This blog delves deep into what are the stages of a cyber attack lifecycle, and offers insights into how you can fortify your enterprise against these multifaceted risks.

The Cyber Attack Lifecycle: A Brief Overview

The cyber attack lifecycle outlines the steps cybercriminals typically follow to execute a successful attack. These stages can vary but generally include the following:

1. Reconnaissance
2. Weaponisation
3. Delivery
4. Exploitation
5. Installation
6. Command and Control (C2)
7. Actions on Objectives

Let’s explore each stage to grasp its nuances and learn how organisations can safeguard themselves.

1. Reconnaissance

In this initial phase, attackers actively or passively collect information about their target – this data often includes IP addresses, network services, and potential vulnerabilities. Reconnaissance plays a major role in red teaming engagements to determine an organisation’s external threat landscape on the internet.

2. Weaponisation

In the weaponisation stage, the attacker creates a “weapon” (for example a piece of malware)  and bundles it with an exploit. Keeping your software updated and training your staff through Awareness Training can help negate such typical attacks. 

3. Delivery

Here, the attacker delivers the weapon to the target through various channels, such as email phishing or exploiting software vulnerabilities. Penetration Testing can simulate these types of delivery methods to assess your organisation's preparedness.

4. Exploitation

Upon reaching the target, the weaponised payload exploits a vulnerability to execute its code. It is good practice to continuously keep your systems patched & secured, and cyber security solutions configured correctly.

5. Installation

Post-exploitation, malware or another malicious payload is installed on the target system. Strong endpoint, network, and cloud security solutions can effectively mitigate this risk.

6. Command and Control (C2)

The attacker now establishes a “command and control” link to remotely control the compromised system. Effective network segmentation and monitoring can help detect and cut off C2 traffic.

7. Actions on Objectives

Finally, the attacker performs actions to achieve their objectives, such as data exfiltration, data encryption for ransom, or system damage. By this stage, quick and decisive Incident Response measures are crucial to mitigate as much damage as possible.
