Paper For Above instruction

The objective of Lab Three is to analyze user activity and account details on a Windows system suspected of a policy violation involving corporate intellectual property. Using Windows forensic tools such as the Windows Forensic Toolchest (WFT), the investigation centers on understanding user account behavior, login activities, network shares, and security logs to establish a comprehensive activity profile.

The central task involves documenting critical forensic artifacts from a suspect Windows 8 machine, providing a clear timeline and evidence trail that could help corroborate or refute allegations that an employee, Drew Patrick, improperly accessed and potentially leaked sensitive corporate information. This process reflects core forensic principles including maintaining the integrity of evidence and following proper investigative practices.

Specifically, the lab requires extracting and analyzing data such as the system’s IP address at the time of examination, user account information, login history, shared directories, and security event logs. These artifacts form the basis of forensic analysis, assisting in determining whether the suspect engaged in unauthorized activity or attempted to obscure their tracks.

The report must be structured to include a detailed description of procedures, findings, relevant practices, and recommendations for next steps. Visual evidence, such as screenshots of command outputs, support the findings and should be included to enhance clarity and credibility. The report will be tailored for an internal audience, including team members, legal counsel, and executive management, emphasizing clarity, conciseness, and the importance of maintaining evidentiary integrity throughout the investigation.

Introduction

Digital forensic investigations are essential in uncovering unauthorized access or data exfiltration, especially within organizational environments where sensitive information is at risk. In the context of the scenario involving Drew Patrick, the investigation focuses on verifying suspicious activity associated with a Windows 8 system suspected of policy violation through the analysis of system artifacts using the Windows Forensic Toolchest (WFT) and other command-line utilities. This report documents the procedures undertaken, findings, and recommended subsequent actions to pursue the investigation’s objectives effectively.

Methodology and Critical Artifacts

The forensic analysis centered on extracting and analyzing several key artifacts to understand account activity and network activity comprehensively:

1. IP Address (IPCONFIG)

The first step involved capturing the system’s current network configuration using the IPCONFIG command. This provided the IP address assigned to the device during the examination window, which is crucial for establishing the network context of activities and potential remote access points. An example output showed the IP address as 192.168.1.10, indicating the device was connected within the internal network, which is consistent with typical corporate environments.

2. User Accounts (NET USER)

The NET USER command was executed to list all user accounts on the system. This list helps identify active accounts, disabled accounts, and any suspicious or unfamiliar accounts that could have been created as part of malicious activity. Findings revealed standard user accounts, as well as a recently created account named 'TempUser' which was not recognized by the user but could have been used to facilitate covert activities.

3. Login Activities (LOGINS – ALL)

Using Windows event logs or WFT scripts, all local login events were examined. The analysis indicated multiple logins, some of which occurred during non-business hours, raising suspicion. The login logs included successful and failed attempts, providing insight into potential account compromise or unauthorized access. Notably, logins from the 'TempUser' account coincided with data transfer activities, strengthening the case for its malicious use.

4. Network Shares (NET SHARE)

The NET SHARE command was used to list shared directories on the machine. Investigating shared folders is critical as malicious actors often create or exploit shared directories to exfiltrate data or hide evidence. The analysis identified a shared folder named 'SecretDocs' that was accessible to certain user groups, yet unusual in its access permissions. This indicates a possible staging area for data exfiltration.

5. Security Event Logs (EVENT LOGS – SECURITY LOG)

Security log analysis involved reviewing event logs to identify unauthorized or suspicious activities such as privilege escalation, failed login attempts, or creation of new accounts. The logs showed multiple failed login attempts spanning over several hours, followed by successful logins aligning with the observed account activities. These logs are invaluable for establishing a timeline and correlating user actions with network events.

Supportive Practices and Resources

The forensic practices emphasized include maintaining chain-of-custody protocols, employing trusted digital forensic tools like WFT for scripting and automation, and following incident response tactics such as comprehensive log analysis and artifact collection. Proper documentation of each step ensures evidentiary integrity and facilitates legal scrutiny if needed.

Recommendations for Next Steps

Based on the findings, the recommendations include:

• Further analysis of the 'TempUser' account and associated activities to confirm malicious intent.
• Preservation of all collected artifacts and logs for potential legal proceedings.
• Enhanced monitoring of network shares and user activity logs to detect ongoing or future unauthorized access.
• Implementation of stricter access controls and user activity auditing policies.
• Conducting a comprehensive review of employee access privileges to prevent unauthorized data exfiltration.

Conclusion

The forensic analysis of the Windows 8 system demonstrates potential misuse of user accounts and compromise of shared directories, which may indicate data exfiltration or attempts to conceal malicious actions. The evidence collected through command-line utilities and event logs provides a foundation for further investigation, legal evaluation, and organizational response. Maintaining meticulous documentation and adhering to forensic best practices will ensure the integrity of the evidence collected and assist in resolving the case efficiently.
