212-89 EC Council Certified Incident Handler (ECIH v3) Questions and Answers

In the context of incident handling, the "point of contact" list is essential for ensuring that Sheila, the incident handler working at night, can quickly notify the responsible personnel within the organization about the cyberattack. This list typically includes the contact information of key stakeholders and decision-makers who need to be informed about security incidents, allowing for timely communication, decision-making, and response coordination.

The Volatility framework is a widely used tool for analyzing volatile memory (RAM) dumps. It is especially useful in digital forensics and malware analysis. One of the fundamental tasks in memory analysis is to list the processes that were running on the system at the time the memory dump was taken. Thepslistcommand in the Volatility framework serves this purpose by listing all processes from the process list in memory, which can provide valuable insights into what was happening on the system, including the presence of any malicious processes.

The syntax provided in the answer option corresponds to the usage of thepslistcommand with the Volatility tool, specifying the memory dump file to be analyzed (-f /root/Desktop/memdump.mem) and the profile of the system from which the dump was taken (--profile=Win2008SP1x86). This information is crucial for accurate analysis, as the profile helps Volatility interpret the memory structures correctly.

Synthetic identity theft is a type of fraud where the perpetrator combines real (often stolen) and fake information to create a new identity. This can include combining a real social security number with a fictitious name, or other variations that result in an identity that is not entirely real but has elements that can pass through verification processes. In the scenario described, Adam is creating a new identity using information from different victims, which is characteristic of synthetic identity theft. This type of fraud is particularly challenging to detect and counter because it does not directly impersonate a single real individual but creates a plausible new identity that can be used to open accounts, obtain credit, and conduct transactions that can be financially beneficial to the attacker.

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.

Farheen's activity of using the DD tool to create a sector-by-sector mirror image of the original disk is an example of system preservation. This process is crucial in digital forensics for creating an exact copy of a storage device to ensure that the original data remains unchanged during the investigation. By making a forensic duplication, or image, of the disk, Farheen ensures that the static data on the disk is preserved in its current state for thorough analysis, without altering the original evidence. This step allows investigators to work with a precise replica of the data, protecting the integrity of the original evidence.

Anti-forensics techniques are designed to prevent, mislead, or interfere with the incident handling process, affecting the collection, preservation, and identification phases of the forensic investigation process. These techniques include methods to erase, encrypt, or alter information, make data recovery difficult, hide data (e.g., steganography), or otherwise obstruct forensic analysis and investigation efforts. Anti-forensics can significantly challenge the efforts of incident responders and forensic investigators in establishing the facts of a security incident or crime.

When an attacker installs a fake AP (Access Point) within a company's network, especially behind a firewall, this constitutes the deployment of a Rogue Access Point. Rogue APs are unauthorized wireless access points installed within a network without the network administrator's knowledge or consent. They pose a significant security risk because they can be used to intercept sensitive information, bypass network security configurations, and provide a gateway for attackers to enter the network undetected. This type of attack circumvents the security measures put in place by a company, including firewalls, by creating an illicit entry point into the network that is under the control of the attacker.

Cross-site request forgery (CSRF or XSRF) is an attack that tricks the victim's browser into executing unauthorized actions on a website where they are currently authenticated. In this scenario, the attacker exploits the trust that a site has in the user's browser, effectively forcing the browser to perform actions without the user's knowledge or consent. For example, if the user is logged into their bank's website, an attacker could craft a malicious request to transfer funds without the user's direct interaction. CSRF attacks rely on authenticated sessions and typically target state-changing requests to compromise user or application data.

When Joseph, the IH&R team lead, alerted service providers, developers, and manufacturers about the affected resources, he was engaged in the Containment stage of the Incident Handling and Response (IH&R) process. Containment involves taking steps to limit the spread or impact of an incident and to isolate affected systems to prevent further damage. Alerting relevant stakeholders, including service providers and developers, is part of containment efforts to ensure that the threat does not escalate and that measures are taken to protect unaffected resources. This stage precedes eradication and recovery, focusing on immediate response actions to secure the environment.

Incident triage is the phase in the incident handling and response process where identified security incidents are analyzed, validated, categorized, and prioritized. This step is critical for determining the severity of incidents and deciding on the allocation of resources for effective response. It involves initial analysis to understand the nature of the incident, its impact, and urgency, which guides the subsequent response actions.

Wireshark is a widely used network protocol analyzer that helps in capturing and interactively browsing the traffic on a network. It is an essential tool for incident responders like Eric who are developing incident-handling plans and procedures. By analyzing network traffic, Wireshark allows users to see what is happening on their network at a microscopic level, making it invaluable for troubleshooting network problems, analyzing security incidents, and understanding network behavior. Whois is used for querying databases that store registered users or assignees of an Internet resource. Burp Suite is a tool for testing web application security, and FaceNiff is used for session hijacking within a WiFi network, which makes Wireshark the best choice for analyzing network traffic.

A Permanent Denial-of-Service (PDoS) attack, also known as "phlashing," is a form of attack that targets hardware, causing irreversible damage to the hardware components, thereby making the device unusable without a replacement or significant hardware intervention. In the scenario described with Zaimasoft, the attackers' actions leading to the damage of hardware components align with the characteristics of a PDoS attack. Unlike Distributed Denial-of-Service (DDoS) or Denial-of-Service (DoS) attacks, which generally aim to overwhelm a system's resources temporarily, or DRDoS (Distributed Reflection Denial of Service), which involves amplification techniques using third-party servers, a PDoS attack directly damages the physical hardware, necessitating its replacement or reinstallation. This makes PDoS particularly severe due to its permanent impact on the targeted organization's hardware infrastructure.

The scenario described is characteristic of a Trojan. A Trojan is a type of malware that disguises itself as legitimate software but performs malicious actions once installed. Unlike viruses, which can replicate themselves, or worms, which can spread across networks on their own, Trojans rely on the guise of legitimacy to trick users into initiating their execution. In this case, the user believed they were downloading and installing genuine software, but the reality was that the application contained a Trojan. The malicious code executed upon installation provided unauthorized remote access to the user's computer, which could be used by an attacker to control the system, steal data, install additional malware, or carry out other malicious activities.

Trojans can come in many forms and can be used to achieve a wide range of malicious objectives, making them a versatile and dangerous type of cyber threat. The deceptive nature of Trojans, exploiting the trust users have in what appears to be legitimate software, is what makes them particularly effective and widespread.

Threat correlation is a method used by incident responders to analyze and associate various indicators of compromise (IoCs) and alerts to identify genuine threats. By correlating data from multiple sources and applying intelligence to distinguish between unrelated events and coordinated attack patterns, responders can significantly reduce the rate of false-positive alerts. This enables teams to prioritize their efforts on the most critical and likely threats, thereby reducing potential risks and corporate liabilities. Effective threat correlation involves the use of sophisticated security information and event management (SIEM) systems, threat intelligence platforms, and analytical techniques to identify relationships between seemingly disparate security events and alerts.

ISO/IEC 27002 is a standard that provides best practice recommendations on information security controls for use by those responsible for initiating, implementing, or maintaining information security management systems (ISMSs). It covers areas such as risk assessment, human resource security, operational security, and communications security, among others, providing a framework for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving an ISMS. ISO/IEC 27035 pertains to information security incident management, PCI DSS (Payment Card Industry Data Security Standard) deals with the security of cardholder data, and RFC 2196 is a guide for computer security incident response teams (CSIRTs), not a standard for implementing ISMSs.

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.

MxToolbox is an online tool that provides various network diagnostics and email security checks, including looking up DNS and MX records, SPF records, and more. It can be used by incident handlers to prevent the organization against evolving email threats by analyzing domain health, checking blacklists, verifying email delivery issues, and more. While Email Header Analyzer is useful for analyzing specific emails for traces of phishing or spoofing, G Suite Toolbox might be specific to Google's services, and Gpg4win is more focused on email encryption. MxToolbox provides a broader set of functionalities for monitoring and troubleshooting email delivery issues and security threats, making it a versatile tool for incident handlers.

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.

Hex encoding (also known as hexadecimal encoding) involves converting binary data into hexadecimal representation. In the context described, when a user submits a request with potentially malicious input (such as a single quote and other characters in an attempt to perform SQL injection), the encoding technique converts this input into a string of hexadecimal digits (ranging from 0 to 9 and A to F). This prevents the direct interpretation of the input as SQL commands by the database, thereby mitigating the risk of SQL injection attacks. This method is a form of input sanitization that helps ensure that user input cannot be used to manipulate database queries directly.

Software as a Service (SaaS) offers the least amount of security responsibility for the end-user or organization, as the service provider manages the underlying infrastructure, software maintenance, security patching, and updates. Choosing a SaaS application means the colleague's organization would not be responsible for the physical servers, operating systems, or the application's security configurations, making it the best option for minimizing their security responsibilities.

Disabling security options such as two-factor authentication (2FA) and CAPTCHA is not a countermeasure to eradicate cloud security incidents. In fact, it is contrary to best security practices. 2FA adds an additional layer of security by requiring two forms of verification before granting access to an account or system. CAPTCHA helps prevent automated attacks by ensuring that the entity accessing the service is human. Both are important security measures that protect against unauthorized access and automated attacks, thereby enhancing cloud security.

Wireshark is a network protocol analyzer that allows users to capture and interactively browse the traffic running on a computer network. It is a crucial tool for incident responders like Eric who are developing incident-handling plans and need to analyze network traffic and patterns. Wireshark can provide detailed information about the network, including protocols used, source and destination of packets, and potential signs of malicious activity, making it invaluable for developing informed policies and procedures.

When Investigator Ian gives you a drive image to investigate, the type of analysis you are performing is static analysis. Static analysis involves examining the contents of a drive, file, or binary without executing the system or the application. It's about analyzing the data at rest. This type of analysis is crucial for forensics investigations because it allows for the examination of files, directories, and system information without altering any state or data, thereby preserving the integrity of the evidence. Static analysis is contrasted with dynamic analysis, which involves analyzing a system in operation (real-time or live) or executing the application to observe its behavior.

While technical solutions like antivirus updates, disabling HTML in emails, and web proxy filtering play significant roles in securing email systems, the best method to prevent email incidents is often considered to be end-user training. This is because many email threats, such as phishing, rely on exploiting user behavior rather than technical vulnerabilities. By educating users on the risks associated with suspicious emails, how to recognize potentially harmful messages, and the importance of not clicking on unknown links or attachments, organizations can significantly reduce the risk of email-related incidents. End-user training empowers individuals to act as a critical line of defense against email-based threats, complementing technical safeguards.

For memory dump analysis, tools like Scylla and OllyDumpEx are more suited. These tools are designed to analyze and extract information from memory dumps, which can be crucial for understanding the state of a system at the time of an incident. Scylla is used for reconstructing imports in dumped binaries, while OllyDumpEx is an OllyDbg plugin used for dumping process memory. Both tools are valuable for incident handlers like Rinni who are performing memory dump analysis to uncover evidence or understand the behavior of malicious software.

In Wireshark, to identify ICMP ping sweep attempts, the filtericmp.type == 8 or icmp.type ==0is used. This filter captures ICMP echo requests and echo replies, which are indicative of ping commands. Type 8 represents an echo request used when a source sends a ping, and type 0 represents an echo reply, which is the response from the target. By filtering for these ICMP types, Miko can detect a surge in ping requests across the network, which could indicate a ping sweep attempt—an exploratory activity often used by attackers to discover active hosts on a network by sending ping requests to multiple addresses.

Thenetstat -abcommand is useful in Windows operating systems for displaying all connections and listening ports, along with the executable involved in creating each connection or listening port. This can be particularly valuable for an incident responder like James when attempting to determine which processes are running on a system and how they are communicating over the network. This information can help identify malicious processes, unauthorized connections, or other signs of compromise on the system. Whilenetstat -abdoes not exclusively list executable files for running processes, it ties processes to network activity, which is a critical part of collecting volatile information during a cybersecurity incident investigation.

In the incident handling and response (IH&R) process, backing up the data on affected systems is a critical step that usually falls under the Containment phase. The Containment phase is crucial for limiting the scope and severity of an incident, ensuring that it does not spread further or affect additional systems. Backing up affected systems during containment is essential for several reasons: it preserves a snapshot of the system in its current state for forensic analysis, ensures that data is not lost if the system needs to be wiped or altered during the response process, and helps in the recovery process if data is corrupted or lost.

By performing a complete backup of the infected system during the Containment phase, Alice ensures that there is a reliable copy of all data and system states before any major actions, such as eradication or deeper forensic analysis, are taken. This step is also preparatory for the potential use of the backup in analyzing how the incident occurred and in restoring system functionality after the incident is resolved.

Omnipeek is a network analyzer tool that allows for the capture and analysis of data packets transmitted across a network. It is designed to provide deep insights into network traffic, enabling users to examine various aspects of the data packets, including network protocols, ports, devices, and potential issues in network transmission. This tool would be ideal for Chandler, who is targeting the Technote organization with the intent of intercepting and analyzing network traffic to obtain sensitive organizational information. Omnipeek's capabilities in packet analysis make it suitable for such activities, offering detailed visibility into the network's operation and data flows.

Incident triage is the stage in the incident response process where the incident handler, like Mike, performs an initial assessment of the reported incident to determine its validity, severity, and potential impact. This includes analyzing the incident to verify if it is a genuine threat or a false positive. The purpose of incident triage is to prioritize incidents based on their criticality and ensure that resources are allocated effectively to address the most serious threats first. This stage is crucial for efficient incident management, as it helps in filtering out false alarms and focusing on real security incidents that require immediate attention.

Incident response orchestration refers to the process and technologies used to coordinate and streamline the response to security incidents. This approach ensures that incident response teams have clear procedures and workflows to follow, enabling them to act swiftly and effectively when dealing with security incidents. By orchestrating the response, organizations can minimize the impact of incidents, ensure consistent and thorough investigation and remediation activities, and improve their overall security posture. Incident response orchestration involves integrating various security tools, automating response actions where possible, and providing a centralized platform for managing incidents.

Nation-state attribution involves identifying a specific country or government as the sponsor behind a cyber-attack or intrusion. This type of threat attribution is focused on determining the involvement of state actors in cyber operations against specific targets, which often involves sophisticated, well-planned, and executed cyber campaigns. Alexis's efforts to identify and attribute the actors behind the attack to a specific nation-state fall under this category, as she seeks to uncover the geopolitical motives and the extent of state sponsorship behind the incident. Nation-state attribution requires analyzing a variety of indicators, including technical evidence, tactics, techniques, and procedures (TTPs), and contextual intelligence. This is distinct from campaign attribution, which focuses on linking attacks to a specific campaign or operation, true attribution, which aims at identifying the actual individuals behind an attack, and intrusion set attribution, which involves attributing a set of malicious activities to a particular threat actor or group.

The correct flow of stages in an Incident Handling and Response (IH&R) process as outlined in the Incident Handler (ECIH v3) by EC-Council begins with Preparation. This phase involves getting ready for potential incidents by developing plans, policies, and procedures, and ensuring that tools and team training are up to date. Incident Recording is the next stage, where incidents are documented and reported. Incident Triage follows, prioritizing incidents based on their impact and urgency. Containment is next, aiming to limit the damage of the incident and prevent further spread. Eradication comes after containment, where the root cause of the incident is removed. Recovery is the stage where affected systems are restored to their operational status. Post-Incident Activities conclude the process, reviewing and learning from the incident to improve future response efforts.

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.

Generation-based fuzz testing is a strategy where new test data is generated from scratch based on a predefined model that specifies the structure, type, and format of the input data. This approach is systematic and relies on a deep understanding of the format and protocol of the input data to create test cases that are both valid and potentially revealing of vulnerabilities. This contrasts with mutation-based fuzz testing, where existing data samples are modified (mutated) to produce new test cases, and log-based and protocol-based fuzz testing, which use different approaches to test software robustness and security.

The port scanning technique that involves resetting the TCP connection between the client and server abruptly before the completion of the three-way handshake, thereby leaving the connection half-open, is known as a Stealth scan (also referred to as a SYN scan). This technique allows the scanner to inquire about the status of a port without establishing a full TCP connection, making the scan less detectible to intrusion detection systems and less likely to be logged by the target. It's a method used to discreetly discover open ports on a target machine without establishing a full connection that would be visible in logs.

According to the National Institute of Standards and Technology (NIST), which is a primary source for cloud computing standards and guidelines, the five main actors in cloud computing are Consumer, Provider, Carrier, Auditor, and Broker. These roles are defined as follows:

Consumer: The person or organization that uses cloud computing services.

Provider: The entity that provides the cloud services to consumers.

Carrier: The organization that offers connectivity and transport services to cloud providers and consumers.

Auditor: An independent party that assesses and verifies the cloud services, security controls, and operations.

Broker: An entity that manages the use, performance, and delivery of cloud services, and negotiates relationships between cloud providers and consumers.

These actors play critical roles in the ecosystem of cloud computing, ensuring the services are delivered and used securely, efficiently, and effectively.

Forensic readiness refers to an organization's ability to maximize its capability to use digital evidence effectively in an investigation, while minimizing the cost of an investigation and disruption to its operations. It involves having policies, procedures, and technologies in place to collect, preserve, and analyze digital evidence efficiently, so when an incident occurs, the organization is prepared to handle it quickly and with minimal costs. Forensic readiness not only helps in reducing the time and resources spent on investigations but also ensures that the evidence is reliable and can be used in legal proceedings if necessary.

A Denial-of-Service (DoS) attack is characterized by flooding the network with a high volume of traffic to consume all available network resources, preventing intended or authorized users from accessing system, network, or applications. This type of attack aims to overwhelm the target's capacity to handle incoming requests, causing a denial of access to legitimate users. Unlike XSS (Cross-Site Scripting) attacks, URL manipulation, or SQL injection, which exploit vulnerabilities in web applications for unauthorized data access or manipulation, a DoS attack specifically targets the availability of services.

The correct sequence of steps involved in forensic readiness planning, based on the activities described, is as follows:

Identify the potential evidence required for an incident.

Determine the source of the evidence.

Define a policy that determines the pathway to legally extract electronic evidence with minimal disruption.

Establish a policy for securely handling and storing the collected evidence.

Identify if the incident requires full or formal investigation.

Train the staff to handle the incident and preserve the evidence.

Create a special process for documenting the procedure.

Reducing the success rate of SQL injection attacks is focused on minimizing vulnerabilities within the application's database interactions, rather than the broader server or network services. SQL injection prevention techniques typically involve input validation, parameterized queries, and the use of stored procedures, rather than changes to the network or server configuration.

A) Closing unnecessary application services and ports on the server is a general security best practice to reduce the attack surface but does not directly impact the success rate of SQL injection attacks. This action limits access to potential vulnerabilities across the network and server but doesn't address the specific ways SQL injection exploits input handling within web applications.

B) Automatically locking a user account after a predefined number of invalid login attempts within a predefined interval can help mitigate brute force attacks but has no direct effect on preventing SQL injection, which exploits code vulnerabilities to manipulate database queries.

C) Constraining legitimate characters to exclude special characters and D) Limiting the length of the input field are both direct methods to reduce the risk of SQL injection. They focus on controlling user input, which is the vector through which SQL injection attacks are launched. By restricting special characters that could be used in SQL commands and limiting input lengths, an application can reduce the potential for malicious input to form a part of SQL queries executed by the backend database.

Alert Logic is a cloud-based security tool that provides Security-as-a-Service solutions including threat management, vulnerability assessment, and improved security outcomes. It is designed specifically to secure cloud resources and services, making it an ideal choice for organizations like Sam Morison Inc. that are moving their operations to the cloud and are concerned about the security of their data. Tools like Nmap, Burp Suite, and Wireshark, while valuable in certain contexts, do not offer the same cloud-focused security capabilities as Alert Logic.

Netcraft is a tool that provides internet security services, including the detection of phishing and spam emails. It offers a range of services that can help organizations identify fraudulent websites and phishing activities by analyzing web content and email messages for known phishing signatures and heuristics. This makes it a useful tool for incident handlers like Francis, who is tasked with detecting phishing and spam emails for client organizations. Other options listed, such as Nessus (a vulnerability scanner), BTCrack (a Bluetooth pin and link-key cracker), and Cain and Abel (a password recovery tool), do not specialize in detecting phishing or spam emails but serve different purposes in cybersecurity.

The DBCC LOG command is used in SQL Server environments to analyze the transaction log files of a database. It provides insights into the transactions that have occurred, which is crucial for forensic analysis in the event of an incident. The syntaxDBCC LOG(<database_name>, <output_level>)allows an incident handler to specify the level of detail they wish to retrieve from the log files. When an incident handler like Adam requires the full information on each operation along with the hex dump of the current transaction row, the output parameter should be set to 4. This level of output is the most verbose, providing comprehensive details about each transaction, including a hex dump which is essential for a deep forensic analysis. It helps in understanding the exact changes made by transactions, which can be pivotal in investigating incidents involving data manipulation or other unauthorized database activities.

Fragmentation is a technique used by attackers to evade detection by Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS). By breaking down packets into smaller fragments, attackers can make it more difficult for these security systems to detect malicious payloads or signature-based patterns associated with known attacks. This method exploits the fact that some IDS/IPS solutions may not properly reassemble packet fragments for analysis, thereby allowing malicious fragments to pass through undetected.

Evidence assessment is a critical step in the investigation phase of the computer forensics process. This step involves evaluating the evidence collected to determine its relevance and significance to the case at hand. It includes analyzing the secured data to identify what information can be used as evidence, its integrity, and how it can be related to the security incident. This phase is pivotal as it helps in building a coherent understanding of the incident and in establishing facts that can be presented in management reports or legal proceedings.

In Wireshark, the filtericmp.type==8is used to detect ping sweep attempts. ICMP type 8 messages are echo requests, which are used in ping operations to check the availability of a network device. A ping sweep involves sending ICMP echo requests to multiple addresses to discover active devices on a network. By filtering for ICMP type 8 messages in Wireshark, Bran can identify these echo requests, helping to pinpoint ping sweep activities on the network.

Network forensic tools are designed to capture, record, and analyze network traffic. Tools like Capsa Network Analyzer, Tcpdump, and Wireshark are specifically designed for this purpose, providing capabilities to capture live traffic, analyze packets, and understand network activities. Capsa Network Analyzer is a comprehensive network monitoring tool, Tcpdump is a powerful command-line packet analyzer, and Wireshark is a widely used network protocol analyzer that provides detailed information about network traffic.

Advanced NTFS Journaling Parser, on the other hand, is not a network forensic tool but a tool used for forensic analysis of NTFS file systems. It parses the NTFS journal ($LogFile), which contains a log of changes made to files on an NTFS volume. This tool is valuable for forensic analysts who are investigating the file system activities on a Windows system, such as file creation, modification, and deletion times, rather than analyzing network traffic. Therefore, it does not fit the category of a network forensic tool.
