Once attackers have successfully weaponised their malicious tools, the next step in the Cyber Kill Chain is delivery. This stage involves transmitting the crafted payload to the intended target. Common delivery methods include phishing emails, malicious attachments, compromised websites, and even physical media like USB drives. This step is critical because it bridges the gap between the attacker’s preparation and the exploitation of vulnerabilities within the target. If an organisation can stop the attack at this stage, it effectively neutralises the threat before it can gain any traction. Syscomm’s defence in depth strategy provides a robust shield against delivery attempts by integrating multiple proactive and reactive measures to block malicious payloads.
The delivery stage is often where attackers rely on human error. Phishing remains one of the most prevalent delivery methods, with attackers crafting deceptive emails designed to trick users into clicking on links or downloading malicious attachments. To counter this, Syscomm deploys advanced email security solutions that serve as the first line of defence. These solutions utilise machine learning and AI to scan incoming emails for indicators of compromise, such as suspicious links, spoofed domains, or malware-laden attachments. Email filtering systems isolate potentially dangerous messages, ensuring that they never reach an employee’s inbox.
Complementing email security is Syscomm’s focus on security awareness training. Employees are often the target during the delivery phase, making their awareness and vigilance a crucial defence layer. Through ongoing phishing simulations and training sessions, Syscomm equips employees to recognise and report suspicious communications. This training not only reduces the likelihood of successful delivery but also creates an additional layer of monitoring, as employees can flag attempts that automated systems might miss.
In addition to protecting against email-based delivery methods, Syscomm addresses web-based attacks through Web Filtering and DNS Security. Attackers often use malicious websites or compromised third-party platforms to deliver payloads. Syscomm’s solutions monitor and block access to such sites, either by identifying known bad URLs or by analysing site behaviour in real time. For example, if a phishing email contains a link to a fraudulent website, the web filtering system will prevent employees from accessing it, stopping the attack in its tracks.
Zero Trust Network Access (ZTNA) plays a significant role in mitigating delivery attempts. By enforcing strict access policies based on identity, device health, and location, Syscomm ensures that even if a malicious payload is delivered, it cannot be executed without meeting stringent criteria. This zero-trust approach ensures that only authorised users and devices can interact with critical systems, further reducing the risk of successful delivery.
Syscomm’s Endpoint Detection and Response (EDR) solutions also come into play during the delivery phase. EDR systems monitor endpoint devices for any signs of malicious activity, such as the execution of suspicious files or processes. For instance, if a payload is delivered via a malicious USB drive or a compromised application, EDR tools can quickly identify and quarantine the threat. By providing real-time detection and response capabilities, these solutions ensure that even if a payload bypasses other defences, it is swiftly neutralised before causing harm.
Another critical layer in Syscomm’s defence is the use of sandboxing technologies. These systems analyse files and attachments in isolated environments to determine their intent before allowing them to reach the user. For example, if an email attachment contains a script designed to execute malware, sandboxing will detect and block it without exposing the organisation’s network to risk. This proactive measure is particularly effective against zero-day threats, which exploit vulnerabilities that are not yet widely known or patched.
To further enhance protection, Syscomm incorporates Conditional Access policies and Multi-Factor Authentication (MFA). These controls ensure that even if an attacker successfully delivers their payload, they cannot easily gain access to systems or data. For instance, conditional access policies can block access from untrusted locations or devices, while MFA adds an additional layer of verification to prevent unauthorised logins.
In addition to these proactive measures, Syscomm integrates Threat Intelligence into its delivery defences. By staying informed about emerging attack techniques, Syscomm ensures its customers are always one step ahead. For example, if a new phishing campaign is targeting a specific sector, threat intelligence feeds can update email filters and endpoint protections with the latest indicators of compromise (IoCs), enhancing their effectiveness against current threats.
Syscomm’s layered approach to the delivery stage highlights the importance of both technology and people in cybersecurity. By combining advanced tools like email security, web filtering, and EDR with employee training and strict access controls, Syscomm ensures that attacks are intercepted before they can reach their targets. This multi-pronged strategy not only blocks known threats but also adapts to new and evolving delivery methods, providing a robust and future-proof defence.
The delivery stage is often seen as the attacker’s first significant interaction with the target. Blocking their payload at this point disrupts the entire attack chain and forces the attacker to go back to the drawing board. Syscomm’s expertise in defending against delivery attempts ensures that customers are well-protected, minimising risk and maintaining business continuity.
As we continue this blog series, we’ll explore the next phase of the Kill Chain: Exploitation. This is where attackers attempt to exploit vulnerabilities to execute their payloads. Syscomm’s defence in depth strategy ensures that even if a payload is delivered, it cannot progress to this stage.
