Detect data-staging activity (MITRE ATT&CK T1074) by analyzing EDR/Sysmon process-creation and file-system telemetry (Event ID 4688, Sysmon 1/11) for 7-Zip/RAR/tar archive creation, unusual temp or hidden folder access, and anomalous consolidation of files from multiple directories. Use when hunting for pre-exfiltration staging behavior, building detection rules for archiver abuse, or validating monitoring coverage for T1074.

# Hunting for Data Staging Before Exfiltration
## Overview
Before exfiltrating data, adversaries typically stage collected files in a central location (MITRE ATT&CK T1074). This involves creating archives with tools like 7-Zip, RAR, or tar, consolidating files from multiple directories, and using temporary or hidden staging directories. This skill detects staging behavior by analyzing process creation logs for archiver activity, monitoring file system events in common staging paths, and identifying anomalous file consolidation patterns.
## When to Use
- When investigating security incidents that require hunting for data staging before exfiltration
- When building detection rules or threat hunting queries for this domain
- When SOC analysts need structured procedures for this analysis type
- When validating security monitoring coverage for related attack techniques
