What logs do I need to collect for webshell detection and threat hunting?▼

Webshell detection requires sysmon logs, Windows Security Event Logs, web server logs, and threat intelligence feeds to accurately analyze process creation events and anomalous HTTP patterns.

Does this webshell detection approach work with Splunk, Elastic, and CrowdStrike?▼

Yes, webshell threat hunting integrates with EDR platforms and SIEM systems including CrowdStrike, Microsoft Defender for Endpoint, Splunk, Elastic, and Sysmon for analyzing process trees and log data.

How do I investigate suspicious process spawning from my web server?▼

Investigate suspicious process spawning by examining process creation logs and process trees to identify anomalous child processes originating from web server applications, indicating potential webshell deployments.

Can I run customized detection queries to hunt for specific webshell indicators?▼

Yes, you can run customizable detection queries based on specific indicators and thresholds to hunt for webshell activity across file creation events, network traffic, and web access logs.

What's the best way to perform a webshell hunt on a specific server?▼

Perform a webshell hunt on a specific server by executing a threat hunting query against its web server logs, sysmon data, and Windows Security Event Logs to identify anomalous HTTP patterns and suspicious processes.
