Offense vs defense T1114.001

Is defensive coverage keeping up with adversary use? Eight counts, each ranked against all 697 ATT&CK techniques. Attack sits left, defense right, so a shape leaning left means adversaries are better documented here than defenders are equipped. Hover any spoke for its percentile and the share of techniques that have more. The timeline below shows when each side arrived.

Local Email Collection detection strategy DET0047

MITRE names one behaviour worth catching for this technique and breaks it into 1 analytic, one per platform. Each carries the log sources it needs and the fields you tune per environment.

Detect Local Email Collection via Outlook Data File Access and Command Line Tooling

Enterprise

1 platform

AN0130 · Windows

Detection focuses on processes that attempt to locate, access, or exfiltrate local Outlook data files (.pst/.ost) using file system access, native Windows utilities (e.g., PowerShell, WMI), or remote access tools with file browsing capabilities. The behavior chain includes directory enumeration, file access, optional compression or staging, and network transfer.

Log sources

The data this analytic draws on. You do not need every component — each one you already collect covers part of it. Each links to its ATT&CK record.

Data component	Name	Channel
Process CreationDC0032	WinEventLog:Sysmon	EventCode=1
File CreationDC0039	WinEventLog:Sysmon	EventCode=11
File AccessDC0055	WinEventLog:Security	EventCode=4663, 4670, 4656
Network Connection CreationDC0082	WinEventLog:Sysmon	EventCode=3, 22

Tunable fields

MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.

Field	What you tune
TargetFilePathPattern	Regex or wildcard patterns for sensitive Outlook file paths (.ost/.pst) depending on organizational deployment.
TimeWindow	Timeframe used to correlate related file access, process creation, and exfiltration events.
UserContext	Limit detection to user accounts not normally interacting with Outlook file locations (e.g., service accounts, low-privileged users).
ProcessAllowList	Filter known legitimate Outlook-accessing processes to reduce false positives.

Email Collection with PowerShell Get-Inbox

windows

PowerShell

—

Yes

Search through local Outlook installation, extract mail, compress the contents, and saves everything to a directory for later exfiltration. Successful execution will produce stdout message stating "Please be patient, this may take some time...". Upon completion, final output will be a mail.csv file. Note: Outlook is required, but no email account necessary to produce artifacts.

Input arguments

Name	Type	Default	Description
file_path	string	PathToAtomicsFolder\T1114.001\src	File path for Get-Inbox.ps1
output_file	string	$env:TEMP\mail.csv	Output file path

Attack command

powershell -executionpolicy bypass -command "#{file_path}\Get-Inbox.ps1" -file #{output_file}

Cleanup command

Remove-Item #{output_file} -Force -ErrorAction Ignore

Prerequisite

Get-Inbox.ps1 must be located at #{file_path}

Check

if (Test-Path "#{file_path}\Get-Inbox.ps1") {exit 0} else {exit 1}

Satisfy

Invoke-WebRequest "https://raw.githubusercontent.com/redcanaryco/atomic-red-team/master/atomics/T1114.001/src/Get-Inbox.ps1" -OutFile "#{file_path}\Get-Inbox.ps1"
