Hunting for Data Staging Before Exfiltration

Name: hunting-for-data-staging-before-exfiltration
Author: pay4ok-exe

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

Prerequisites

EDR or Sysmon telemetry with process creation and file system events
Windows Event Logs (Event ID 4688) or Sysmon Event ID 1, 11
Python 3.8+ with standard library
Access to process creation logs in JSON/CSV format

Steps

Detect Archive Tool Execution — Monitor for 7z.exe, rar.exe, tar, zip, and WinRAR process creation with compression arguments
Identify Staging Directories — Flag file writes to common staging locations (Recycle Bin, %TEMP%, ProgramData, hidden directories)
Detect Large File Consolidation — Identify patterns of multiple file reads followed by writes to a single directory
Monitor Sensitive Path Access — Track bulk reads from document directories, database paths, and network shares
Analyze Archive Metadata — Extract and analyze archive file sizes, creation times, and source paths
Score Staging Risk — Apply heuristic scoring based on archive size, source diversity, staging path suspicion, and timing
Generate Hunt Report — Produce a structured report with staging event timeline and MITRE ATT&CK mapping

Expected Output

JSON report of detected staging events with risk scores
Archive creation timeline with source file analysis
MITRE ATT&CK mapping (T1074.001, T1074.002, T1560)
Staging directory heat map showing suspicious write activity
