User Discovery

Cybrary
Course

Once on a victim's system, adversaries will perform user discovery to determine information, such as the primary user’s identity and capabilities. They may seek out users with access to remote systems so they can cast their net wider. Discover the attacker instead of the other way around with this dynamic, lab-based course!

Module 1: User Discovery
What is User Discovery?

Hands-On Detection (Lab)

Course Description

Adversaries will attempt to identify the system owner and perform user discovery in support of the overall Discovery tactic. They may do this by pulling account usernames or using credential dumping. They will search for process ownership, directory ownership, and other important information that is available in system logs. By learning who target users are and what their capabilities may be, attackers can plan their next steps. Threat actors like FIN10 have been known to use Meterpreter to enumerate users on remote systems.

It is important to be able to detect this type of activity because mitigating it is difficult, given that it involves abusing normal system features.

Get the hands-on skills you need to detect and mitigate this attack in Cybrary's MITRE ATT&CK Framework courses aligned to the tactics and techniques used by the financially motivated threat group FIN10. Prevent adversaries from accomplishing the tactic of Discovery in your environment today.

What will I be able to accomplish after taking these courses?

  • You will be able to identify and validate critical threats related to threat actor attempts to exfiltrate your organization’s valuable data and potentially attempt to extort your organization for financial gain.
  • You will be able to use a SIEM tool to identify indicators of compromise and validate whether they should be investigated further.
  • You will learn response and mitigation recommendations to keep your organization safe.

What are the prerequisites for these courses?

  • Intermediate-level knowledge of defensive security is required. You should have some experience as a security engineer, SOC or security analyst, or similar role.
  • Familiarity with using a SIEM tool, like Splunk or ELK is strongly recommended.
  • Experience using command-line tools is required.
  • Cybrary's MITRE ATT&CK Defender (MAD) ATT&CK Fundamentals Course is recommended.
  • A basic understanding of offensive security is beneficial. Those who have taken our Offensive Penetration Testing course or our OWASP Top Ten series of courses will be well prepared in this area.
