T1114 Email Collection

High-Level Description

Adversaries may target user email to collect sensitive information. Emails may contain sensitive data, including trade secrets or personal information, that can prove valuable to adversaries. Emails may also contain details of ongoing incident response operations, which may allow adversaries to adjust their techniques in order to maintain persistence or evade defenses. Adversaries can collect or forward email from mail servers or clients.

Kill Chain Phase

• Collection (TA0009)

Platforms: Windows, macOS, Linux, Office Suite

What to Check

• Identify if Email Collection technique is applicable to target environment
• Check Windows systems for indicators of Email Collection
• Check macOS systems for indicators of Email Collection
• Check Linux systems for indicators of Email Collection
• Verify mitigations are bypassed or absent (4 known mitigations)
• Assess detection coverage (1 detection strategies)

How to Test

Manual Testing

1. Identify Attack Surface: Determine if the target environment is susceptible to Email Collection by examining the target platforms (Windows, macOS, Linux).

2. Assess Existing Defenses: Review whether mitigations for T1114 are in place. If defenses are absent or misconfigured, this technique may be exploitable.

3. Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.

Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.

Remediation Guide

M1032 Multi-factor Authentication

Use of multi-factor authentication for public-facing webmail servers is a recommended best practice to minimize the usefulness of usernames and passwords to adversaries.

M1060 Out-of-Band Communications Channel

Use secure out-of-band authentication methods to verify the authenticity of critical actions initiated via email, such as password resets, financial transactions, or access requests. For highly sensitive information, utilize out-of-band communication channels instead of relying solely on email to prevent adversaries from collecting data through compromised email accounts.
