Mark, a security analyst, was tasked with performing threat hunting to detect imminent threats in an organization's network. He generated a hypothesis based on the observations in the initial step and started the threat-hunting process using existing data collected from DNS and proxy logs.
Identify the type of threat-hunting method employed by Mark in the above scenario.
Correct Answer:C
A data-driven hunting method is a type of threat hunting method that employs existing data collected from various sources, such as DNS and proxy logs, to generate and test hypotheses about potential threats. This method relies on data analysis and machine learning techniques to identify patterns and anomalies that indicate malicious activity. A data-driven hunting method can help discover unknown or emerging threats that may evade traditional detection methods. An entity-driven hunting method is a type of threat hunting method that focuses on specific entities, such as users, devices, or domains, that are suspected or known to be involved in malicious activity. A TTP-driven hunting method is a type of threat hunting method that leverages threat intelligence and knowledge of adversary tactics, techniques, and procedures (TTPs) to formulate and test hypotheses about potential threats. A hybrid hunting method is a type of threat hunting method that combines different approaches, such as data-driven, entity-driven, and TTP-driven methods, to achieve more comprehensive and effective results.
A web application, www.moviescope.com. hosted on your tarqet web server is vulnerable to SQL injection attacks. Exploit the web application and extract the user credentials from the moviescope database. Identify the UID (user ID) of a user, John, in the database. Note: Vou have an account on the web application, and your credentials are samAest.
(Practical Question)
Correct Answer:B
4 is the UID (user ID) of a user, John, in the database in the above scenario. A web application is a software application that runs on a web server and can be accessed by users through a web browser. A web application can be vulnerable to SQL injection attacks, which are a type of web application attack that exploit a vulnerability in a web application that allows an attacker to inject malicious SQL statements into an input field, such as a username or password field, and execute them on the database server. SQL injection can be used to bypass authentication, access or modify sensitive data, execute commands, etc. To exploit the web application and extract the user credentials from the moviescope database, one has to follow these steps:
✑ Open a web browser and type www.moviescope.com
✑ Press Enter key to access the web application.
✑ Enter sam as username and test as password.
✑ Click on Login button.
✑ Observe that a welcome message with username sam is displayed.
✑ Click on Logout button.
✑ Enter sam’ or ‘1’='1 as username and test as password.
✑ Click on Login button.
✑ Observe that a welcome message with username admin is displayed, indicating that SQL injection was successful.
✑ Click on Logout button.
✑ Enter sam’; SELECT * FROM users; – as username and test as password.
✑ Click on Login button.
✑ Observe that an error message with user credentials from users table is displayed.
The UID that is mapped to user john is 4
Camden, a network specialist in an organization, monitored the behavior of the organizational network using SIFM from a control room. The SIEM detected suspicious activity and sent an alert to the camera. Based on the severity of the incident displayed on the screen, Camden made the correct decision and immediately launched defensive actions to prevent further exploitation by attackers.
Which of the following SIEM functions allowed Camden to view suspicious behavior and make correct decisions during a security incident?
Correct Answer:C
Dashboard is the SIEM function that allowed Camden to view suspicious behavior and make correct decisions during a security incident. SIEM (Security Information and Event Management) is a system or software that collects, analyzes, and correlates security data from various sources, such as logs, alerts, events, etc., and provides a centralized view and management of the security posture of a network or system. SIEM can be used to detect, prevent, or respond to security incidents or threats. SIEM consists of various functions or components that perform different tasks or roles. Dashboard is a SIEM function that provides a graphical user interface (GUI) that displays various security metrics, indicators, alerts, reports, etc., in an organized and interactive manner. Dashboard can be used to view suspicious behavior and make correct decisions during a security incident. In the scenario, Camden monitored the behavior of the organizational network using SIEM from a control room. The SIEM detected suspicious activity and sent an alert to Camden. Based on the severity of the incident displayed on the screen, Camden made the correct decision and immediately launched defensive actions to prevent further exploitation by attackers. This means that he used the dashboard function of SIEM for this purpose. Application log monitoring is a SIEM function that collects and analyzes application logs, which are records of events or activities that occur within an application or software. Log retention is an SIEM function that stores and preserves logs for a certain period of time or indefinitely for future reference or analysis. Data aggregation is an SIEM function that combines and normalizes data from different sources into a common format or structure.
