A Trojan attack involves a type of malicious code or software that appears legitimate but can take control of your computer. Trojans often disguise themselves as legitimate software or are hidden within legitimate software that has been tampered with. They differ from viruses and worms because they do not replicate. However, once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system. This can include unauthorized actions such as deleting files, monitoring user activities, or installing additional malicious software.

References:The ECIH v3 course details various forms of malware, including Trojans, their modes of operation, and their impact on information security. Understanding the nature of these threats is crucial for effective incident handling and response.

Turning off the infected machine is a common immediate response to contain a malware incident and prevent it from spreading to other systems on the network. This action halts any ongoing malicious activities by the malware, thereby limiting the potential for further damage or data exfiltration. However, it is essential to note that this step can lead to the loss of volatile data that might be useful for forensic analysis. Therefore, it is advisable only when it's critical to stop the malware immediately, and there's a strategy in place for forensic investigation that includes handling non-volatile data or when the preservation of volatile data is not possible.

References:The Incident Handler (ECIH v3) curriculum by EC-Council outlines various strategies for containing malware incidents, discussing the implications and considerations of actions such as turning off infected machines.

System characterization is the process of defining the boundaries of an IT system, which includes identifying the resources, information, and functionality that constitute the system. This process is crucial for understanding the scope of the system, the data it processes, and the technology it employs. By characterizing a system, incident handlers can better understand the system's normal operations and behaviors, which is essential for identifying anomalies that may indicate a security incident. System characterization involves documenting the hardware, software, network configuration, data flows, and other critical elements of the IT environment. This foundational knowledge supports effective incident handling by providing a baseline against which suspicious activities can be compared.

References:EC-Council's Certified Incident Handler (ECIH v3) courses and study guides emphasize the importance of system characterization in the incident handling and response process. It serves as a prerequisite for subsequent steps such as threat identification, vulnerability identification, and the implementation of appropriate controls.
