It seems you are asking for a structured approach to solve a hypothetical case involving cybersecurity and a political scandal in the fictional city of Valdoria. Below is a step-by-step guide on how you might tackle this scenario, including the techniques you will learn and how to approach the investigation.

Step-by-Step Guide to Investigating the Cyberattack

1. Understanding the Context

– Valdoria is facing a crucial election, and the integrity of the news published by The Valdorian Times is under threat due to unapproved articles alleging corruption against a leading candidate.
– Your goal is to investigate the cyberattack that led to the publication of this article and to uncover the truth.

2. Interpreting Security Logs

– Objective: Identify evidence of malicious activity.
– Review security logs for any unusual access patterns, unauthorized logins, or attempts to modify published content.
– Look for specific indicators of compromise (IoCs), such as suspicious IP addresses or user accounts that accessed sensitive information during odd hours.

3. Using Azure Data Explorer (ADX) and Kusto Query Language (KQL)

– Objective: Query logs to extract pertinent information.
– Construct KQL queries to retrieve relevant data from the logs, such as:SecurityEvent
| where TimeGenerated > ago(30d)
| where EventID == 4625 // Failed login attempts
| summarize Count = count() by User, IPAddress

– Analyze results to identify accounts that may have been targeted during the timeframe of the article’s publication.

4. Interpreting PowerShell Scripts and Malicious Commands

– Objective: Understand the commands executed by attackers.
– Examine any PowerShell scripts or commands found in logs that may have been used during the attack:Get-EventLog -LogName Security | Where-Object { $_.EventID -eq 4688 } | Select-Object TimeGenerated, Message

– Look for commands that could have been used to extract data or manipulate articles published by The Valdorian Times.

5. Formulating Analytical Questions

– Objective: Create questions to guide your investigation.
– Example questions:- What accounts accessed The Valdorian Times’ content management system around the time of the article’s unauthorized publication?
– Were there any failed login attempts that coincided with successful logins from unusual locations?

– Use KQL to answer these questions and gather evidence.

6. Compiling Findings

– Summarize your findings in a report detailing:- The timeline of events leading up to the publication of the article.
– The methods used by the attackers.
– Recommendations to strengthen security measures at The Valdorian Times.

Completion of the Virtual Lab

– After completing the virtual lab on the KC7 platform, ensure you capture your completion certificate or a screenshot that includes your name/user name for credit.
– Submit this documentation as required by your assignment guidelines.

Conclusion

By following these steps, you will be able to effectively track down and analyze the cyberattack against The Valdorian Times. This investigation will not only help bring the truth to light but also equip you with valuable skills in cybersecurity analysis and log interpretation.
