The correct sequence to examine the originating IP address of emails involves first accessing the email's header to locate the IP address, then using external resources to investigate that address further. The steps are as follows:

Step 2:Open the email to trace and find its header. This is the initial step because the header contains valuable information about the email's journey across the internet, including the originating IP address.

Step 3:Collect the IP address of the sender from the header of the received mail. This detail is crucial for the next steps in the investigation.

Step 1:Search for the IP in the WHOIS database. This database can provide information about the owner of the IP address, including the ISP and sometimes the geographic location.

Step 4:Look for the geographic address of the sender in the WHOIS database. With the IP address information obtained from the WHOIS search, the geographic location or the originating country of the email can often be deduced, contributing to the analysis of the email's legitimacy.

The responsibility of first responders does not include shutting down or rebooting the victim’s computer as a measure to preserve temporary and fragile evidence. In fact, such actions can potentially alter or destroy volatile data that could be crucial for the investigation. The primary responsibilities of first responders include protecting and identifying the crime scene, and ensuring the preservation of evidence in its original state as much as possible, which may involve isolating affected systems from the network but not necessarily shutting them down or rebooting them without proper forensic readiness and consideration.

Risk assessment is the risk management process that involves identifying risks, estimating their impact on the organization, and determining the sources of those risks to recommend appropriate mitigation measures. The goal of a risk assessment is to understand the nature of potential threats, vulnerabilities, and the consequences of those risks materializing, allowing an organization to make informed decisions about how to address them effectively. Risk assumption involves accepting the potential impact of a risk, risk mitigation focuses on reducing the likelihood or impact of risks, and risk avoidance involves taking actions to avoid the risk entirely.

Eradication is the step in the incident handling and response process where the root cause of an incident is removed, and measures are taken to close all attack vectors to prevent similar incidents in the future. After an incident has been properly contained to stop it from spreading or causing further damage, the eradication phase focuses on eliminating the source of the incident. This could involve removing malware, closing vulnerabilities, or implementing stronger security measures to address the exploitation paths used by the attacker.

In the scenario with Raven, notifying service providers and developers of affected resources is part of the actions taken to address the root cause of the incident. This ensures that any vulnerabilities or issues that contributed to the incident are fixed. By working to remove the root cause and secure the system against similar attacks, Raven is effectively implementing the eradication step of the incident handling process.
