What Are The Typical Stages of Cyber Attack Lifecycle?

Table of Contents

The stages of the cyber attack lifecycle are- Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control, and Actions on Objectives. These stages involve gathering intelligence, transforming it into a weapon, delivering the attack, exploiting vulnerabilities, establishing access, assuming control, and carrying out the attacker’s goals.

What are the stages of the Cyber Attack Lifecycle?

  1. Reconnaissance: Gathering intelligence about the target’s networks, assets, and vulnerabilities.
  2. Weaponization: Transforming gathered information into a weapon or exploit to breach the target’s defences.
  3. Delivery: Sending the weaponised attack to the target, often through phishing emails, malware-laced links, or malicious attachments.
  4. Exploitation: Taking advantage of vulnerabilities to gain initial access to the target’s systems or network.
  5. Installation: Establishing a secure connection and installing backdoors or malicious software to maintain access.
  6. Command and Control: Assuming control over the compromised systems/networks to execute the attacker’s objectives, such as extracting sensitive information or performing unauthorised actions.
  7. Actions on Objectives: Carrying out the intended goals of the attack, which could include data theft, disruption of operations, ransom demands, or further exploitation of connected systems.

Let’s dive into these seven stages with depth!


The first stage of the attack lifecycle is “Reconnaissance.” During this stage, attackers gather intelligence and research about their target. They aim to gain knowledge about the target’s networks, systems, and potential vulnerabilities. This involves conducting extensive research on various aspects, including the target’s online presence, such as their website and social media platforms.

Attackers may also gather information about the target’s security platform and any publicly available data. The reconnaissance stage allows attackers to identify potential entry points and understand the target’s security posture, which lays the foundation for subsequent stages of a typical cyberattack.

Our Cyber Security Training offers comprehensive training programs designed to educate and empower your employees to recognise and respond to potential cyber threats in the first stage itself! Take the proactive step and Get in touch with us today to build a resilient security culture.


The second stage is “Weaponisation.” In this stage, cyber threats and adversaries take the information gathered during reconnaissance and transform it into weapons or exploits. They carefully select the most effective code or tools to bypass the target’s security defences. The objective is to create a weapon that can breach the target’s security measures and gain access to their systems.

Once weaponised, these tools or exploits are used to infiltrate the target’s network or infrastructure. Attackers leverage their weaponised attacks to move laterally within the system, seeking to achieve their objectives, such as accessing sensitive data, compromising security controls, or gaining unauthorised control over the target’s resources.

During this delivery phase, attackers employ various methods to deliver their malicious payloads and gain initial access to the target’s systems. They may utilise tactics such as spear phishing emails, malware-laced attachments, or malicious links to trick unsuspecting users into executing their payloads. Social engineering techniques can also be employed to manipulate individuals into divulging sensitive information or granting access.

In some cases, attackers may exploit vulnerabilities in remote desktop services or other entry points to gain initial entry. Successful delivery of the attack ensures continued access for the attackers. It establishes a foothold within the target’s environment, enabling them to steal sensitive data, deploy malware, or proceed to subsequent stages of the attack.

In this stage, attackers capitalise on vulnerabilities identified during reconnaissance and weaponisation to gain initial access to the target’s systems. Exploitation involves the utilisation of specific techniques or exploits to breach security defences and gain a foothold within the target’s environment. By successfully exploiting vulnerabilities, attackers ensure continued access and control over the compromised systems.

This stage is crucial as it allows attackers to establish a persistent backdoor, enabling them to move freely within the target’s network, evade detection, and proceed with their malicious activities. Exploitation is a key link in the cyber kill chain, and effective cyber security measures, such as regular patching, vulnerability management, and robust access controls, are essential to mitigate the risk of successful exploitation.

Command and Control

After gaining initial access through exploitation, cyber attackers establish control over the compromised systems or network. In this stage, they deploy malware or establish communication channels to remotely manage and control the compromised environment. By assuming command and control, attackers can execute their objectives, whether it’s exfiltrating sensitive data, launching further attacks, or maintaining persistent access for future exploitation.

Robust cyber resiliency measures, including strong network segmentation, continuous monitoring, and timely incident response, are crucial to limit the attacker’s control and mitigate the impact of their actions. Cyber defenders must also focus on reducing the attack surface and implementing proactive security measures to detect and disrupt command and control activities. By effectively countering this stage, organisations can enhance their cyber defences and minimise the damage caused by successful attacker control.

Actions on Objectives

The stage of “Actions and Objectives” represents the final phase of this lifecycle. At every stage leading up to this point, the attacker has diligently worked to gain access, establish control, and execute their malicious intentions. In this stage, the attacker delivers on their goals and accomplishes the desired outcomes of the attack. This can include activities such as stealing sensitive data, disrupting operations, encrypting files for ransom, or causing reputational damage.

The attacker obtains the information or achieves the objectives they set out to accomplish throughout the attack lifecycle. It is crucial for organisations to prioritise robust cybersecurity measures, continuous monitoring, and rapid incident response to minimise the impact of successful attacks during this stage. By actively defending against the attacker’s actions and objectives, organisations can mitigate the potential damage and regain control over their systems and data.

Real-Life Example in the World of Cyberattack

  • In April 2023, Yum! Brands, the parent company of KFC, Taco Bell, and Pizza Hut, disclosed a cyber attack that occurred in January. Employee personal data was exposed, leading to the company closing down nearly 300 UK locations and incurring costs for security measures, customer notifications, and brand perception.
  • In March 2023, ChatGPT, known for its advanced AI capabilities, experienced a data breach. Users were able to see limited personal information of other users, such as names and email addresses. OpenAI, ChatGPT’s parent company, responded by notifying affected users, verifying emails, and implementing additional security measures. The breach further eroded trust in AI technology.
  • Apple released a critical security patch in response to a vulnerability that allowed the Pegasus virus to exploit iOS 14.7.1, gaining extensive access to Apple devices. The update addressed this zero-day, zero-exploit flaw, safeguarding users’ devices from potential compromise.

What can we learn from the above real-world cybersecurity control examples?
