Lockheed Martin developed the intrusion kill chain, a cybersecurity framework to help teams comprehend the stages of an attack. Drawn from military attack models and applied to digital environments, this framework helps security personnel recognize, detect, and prevent persistent threats.
The cyber kill chain consists of seven core steps attackers typically take when conducting a successful cyberattack. The initial stage is reconnaissance, in which hackers scan out their target’s network and vulnerabilities for potential vulnerabilities.

Who is Gathering Information in the Intrusion Kill Chain?

Reconnaissance is the initial stage in any cybercriminal’s attack chain, where they research and identify their target. This includes uncovering vulnerabilities, exploring potential entry points and scanning for third-party software that could be installed on the network.
Reconnaissance can take place both online and offline, using spying tools or advanced automated scanners to detect potential security breaches. During this stage, hackers may also collect information about the target’s current security systems and finances.
Reconnaissance is the process of identifying any security flaws, such as firewalls, intrusion prevention systems and perimeter networks. Once this data has been gathered, penetration testing can begin to reveal any vulnerabilities.
Once a vulnerability has been identified, attackers create malware to take advantage of it and gain access to the system. The code is tailored specifically for them, decreasing their likelihood of detection by existing security solutions.
Once an attacker has gained access to a system, they often attempt to carry out their desired objectives such as data exfiltration, destruction or encryption for ransom. They may copy, move or reroute confidential data away from its original location where they have more control; this could be used by ransom victims to pay ransom, sell it to unauthorized users or engage in other illegal activities. Once finished with one attack, the perpetrator can launch another one for another goal.

Is Your Cybersecurity Strategy Prepared for Weaponization?

The cyber kill chain is a phase-based model that outlines the steps of an intentional attack, helping security teams prevent and intercept threats at every stage. By applying the military model, cyber teams gain insight into how attackers work and what actions need to be taken in order to stop them.
The initial step in any successful kill chain is reconnaissance, which involves gathering information about the target and its systems. This step is essential as it allows defenders to identify potential vulnerabilities and guard against attacks that could harm or destroy sensitive data.
Weaponization is the next stage in the kill chain and involves creating an attack vector. This could be in the form of malware or ransomware programs that target specific vulnerabilities, as well as tools used for gaining access to systems or other assets within a network.
After successfully executing the weaponization stage of a kill chain, attackers move on to delivery and exploitation. This involves traversing networks in an effort to gain access to vital resources like servers or networks storing confidential data.
The final stage of the cyber kill chain is monetization, or using information obtained during an attack to generate income. This can be done in several ways such as selling sensitive data on the dark web or offering ransom payments to victims.

Is Your Network Vulnerable to the Delivery Stage of the Intrusion Kill Chain?

Cyberattacks have grown increasingly complex and sophisticated over the past two decades, as digital technologies such as cloud computing, robotic process automation and social engineering create new vulnerabilities. To stay abreast of this ever-evolving threat landscape requires continuous security validation across all stages of the cybersecurity kill chain.
In cybersecurity, an intrusion kill chain refers to the series of steps a malicious actor must take in order to successfully steal sensitive information from an organization’s network. It consists of reconnaissance, weaponization, delivery, exploitation, installation and command and control activities.
At the reconnaissance stage, attackers gather intelligence on their target by sending out phishing emails or accessing compromised websites.
They may attempt to break into the target’s network by exploiting software or hardware vulnerabilities. Then they use privilege escalation techniques in order to gain access to more valuable data or systems on the network.
Once inside, hackers may attempt to obscure their activities or launch a denial of service (DoS) attack in an effort to divert security attention away from the core target of their attack. Some cybercriminals may even use this opportunity to install additional malware to gain an added advantage.
To effectively prevent an intrusion, it’s best to catch it at its earliest stage so that more damage can be done. Doing this minimizes time, money and resources spent on remediating after an attack has been detected.

Can You Spot the Weakness in the Exploitation Stage of the Intrusion Kill Chain?

Exploitation is the final stage of an intrusion kill chain that takes place after an attacker has gained access to your system through reconnaissance. At this stage, they will attempt to further access your organization’s systems by exploiting vulnerabilities within your network or other weak points.
At this stage, attackers may use malware to gain further access to your network and install additional tools that facilitate their objectives. They could also lateralize throughout the system, creating new entry points.
Attackers may attempt to hide their activities by employing techniques such as file deletion, binary padding and code signing. These techniques make it appear that no threat exists in the system and distract security teams from discovering attackers’ objectives.
Finally, they may employ privilege escalation techniques to obtain high-level access to other systems and accounts. This gives them the capacity to alter existing information or steal sensitive data.
The cyber kill chain is a framework that outlines the steps an attacker must take in order to succeed. It was first developed by Lockheed Martin in 2011 and has since been adopted by numerous companies as they look for ways to protect against sophisticated attacks. Different security teams may customize this framework in order to create their own security controls.

Can You Prevent an Intrusion with Proper Installation?

The installation step of an intrusion kill chain occurs when an attacker or intruder installs a backdoor or remote access trojan to gain persistence in an environment. They may also take actions such as wiping files and data, altering vital information to thwart investigations or concealing their presence to avoid detection.
Once compromised, cybercriminals can command and control the compromised host or system to fulfill their desired objectives. This may include data theft, encryption for ransom, data exfiltration or even data destruction.
These stages are also known as the lateral movement phase in cybersecurity, since they enable an attacker to penetrate further into a network and access new systems within an organization. To interrupt this stage, one can prevent them from communicating with their target or set measures that limit their impact on the system.
The quicker an enterprise can stop an attack, the less costly and time-consuming it will be. That is why intercepting and stopping an attack at its early stages can reduce the resources required for forensics.

Who Controls the Command and Control in Cybersecurity?

The command and control stage of an intrusion kill chain involves cybercriminals gaining physical access to a compromised target’s system, giving them the power to take actions that further their original goals, such as data theft, destruction or exfiltration.
At this stage, attackers may utilize lateral movement to penetrate deeper into the network and circumvent defenders. They may also employ obfuscation techniques in an effort to make it appear that no threat exists.
They use methods such as file deletion, binary padding and code signing to conceal their activities. They may also launch denial-of-service (DoS) attacks against other systems to divert security teams’ focus away from the attack’s core objectives.
This is a crucial phase of an attack that must be detected and prevented before it has an opportunity to impact your enterprise’s systems or data. The sooner an organization can stop and contain an attack, the easier it will be to remediate it.
Lockheed Martin created the original kill chain framework as a helpful model to help security teams identify the steps an attacker must complete in order to gain access to a target’s network. However, it is not perfect and has some limitations regarding the detection of attacks; for instance, it does not detect insider threats or those using compromised credentials, nor does it take into account other types of assaults, such as web-based attacks and certain Zero Day exploits.
