Scenario:

As a SOC analyst, you aim to investigate a security breach in an Active Directory network using Splunk SIEM (Security information and event management) solution to uncover the attacker's steps and techniques while creating a timeline of their activities. The investigation begins with network enumeration to identify potential vulnerabilities. Using a specialized privilege escalation tool, the attacker exploited an unquoted service path vulnerability in a specific process.

Once the attacker had elevated access, the attacker launched a DCsync attack to extract sensitive data from the Active Directory domain controller, compromising user accounts. The attacker employed evasion techniques to avoid detection and utilized pass-the-hash (pth) attack to gain unauthorized access to user accounts. Pivoting through the network, the attacker explored different systems and established persistence.

Throughout the investigation, tracking the attacker's activities and creating a comprehensive timeline is crucial. This will provide valuable insights into the attack and aid in identifying potential gaps in the network's security.

Instructions:

• Virtualbox: Start the VM and access Splunk from the host machine via http://127.0.0.1:8009. No need to login to the machine
• Credentials: vagrant/vagrant
