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 outlines the steps cybercriminals typically follow to execute a successful attack. These stages can vary but generally include the following:
Let’s explore each stage to grasp its nuances and learn how organisations can safeguard themselves.
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.
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.
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.
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.
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.
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.
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.
Navigating the maze of cyber threats can be overwhelming. However, understanding what the stages of a cyber attack lifecycle provides an opportunity for proactive defence and damage control.
When it comes to cybersecurity, it's always better to be proactive rather than reactive. Trust Infotrust for your cyber security needs, and let’s build a safer digital future together.
