Essential Windows Directories for SOC Analysts, According to Chirag Goswami

In a recent LinkedIn post, Chirag Goswami, founder of Cybernara, highlights critical Windows directories that Security Operations Center (SOC) analysts should be intimately familiar with to enhance threat detection and response capabilities. Goswami emphasizes that understanding these locations can significantly reduce investigation time and help identify malicious activity before it escalates.

Key Windows Directories for Threat Hunting

Goswami breaks down essential directories into several key categories, each serving a distinct purpose in identifying potential security threats. He stresses the importance of these areas for effective threat hunting and incident response.

Credential and Access Logs

One of the primary areas Goswami points out involves directories related to credential and access logs. These locations are crucial as they can contain vital information such as password hashes, backup data, and security policies, which are often targets for attackers seeking to gain unauthorized access or escalate privileges.

As Chirag Goswami notes:

Credential & Access Logs – Password hashes, backups, and security policies

Understanding these logs, according to Goswami, allows analysts to identify suspicious authentication patterns or attempts to compromise user credentials.

System and Event Logs

Another critical category highlighted by Goswami is system and event logs. These logs provide a comprehensive record of system-wide changes, application activities, and security events. For SOC analysts, correlating these events with other indicators is key to building a complete picture of an incident.

Goswami explains the significance:

System & Event Logs – System-wide changes & SIEM correlation points

He argues that these logs are indispensable for SIEM (Security Information and Event Management) systems, enabling analysts to track the timeline of events and identify anomalies.

Malware and Threat Indicators

Goswami also directs attention to directories that serve as repositories for malware and threat indicators. These can include artifacts like Prefetch files, Amcache data, and specific registry keys that are often left behind by malicious software.

In Chirag Goswami’s view:

Malware & Threat Indicators – Prefetch, Amcache, and registry artifacts

By examining these artifacts, analysts can gain insights into the types of malware present, how it executed, and its potential impact.

Persistence and Startup Mechanisms

Finally, Goswami underscores the importance of understanding how attackers establish persistence on compromised systems. This involves knowing the specific folders and registry keys that malicious actors commonly abuse to ensure their code runs automatically upon system startup or login.

According to Chirag Goswami:

Persistence & Startup – Folders and registry keys attackers abuse

Identifying these mechanisms is paramount for ensuring that a threat is fully eradicated and cannot reinfect the system.

The Value of Directory Knowledge for SOC Analysts

Goswami concludes by reiterating the practical benefits of this specialized knowledge. He states that knowing precisely where to look within the Windows operating system can save analysts countless hours of manual searching.

The core message from Goswami’s post is clear:

Why it matters: Knowing where to look saves analysts hours and helps catch attackers before they dig deeper.

This efficiency directly translates into a more proactive and effective security posture. By mastering these key directory locations, SOC analysts can significantly improve their ability to detect and respond to threats swiftly and efficiently. Goswami’s insights offer a practical guide for blue teamers aiming to refine their threat hunting skills.
