T1037 Boot or Logon Initialization Scripts

High-Level Description

Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence. Initialization scripts can be used to perform administrative functions, which may often execute other programs or send information to an internal logging server. These scripts can vary based on operating system and whether applied locally or remotely.

Adversaries may use these scripts to maintain persistence on a single system. Depending on the access configuration of the logon scripts, either local credentials or an administrator account may be necessary.

An adversary may also be able to escalate their privileges since some boot or logon initialization scripts run with higher privileges.

Kill Chain Phase

• Persistence (TA0003)
• Privilege Escalation (TA0004)

Platforms: macOS, Windows, Linux, Network Devices, ESXi

What to Check

• Identify if Boot or Logon Initialization Scripts technique is applicable to target environment
• Check macOS systems for indicators of Boot or Logon Initialization Scripts
• Check Windows systems for indicators of Boot or Logon Initialization Scripts
• Check Linux systems for indicators of Boot or Logon Initialization Scripts
• Verify mitigations are bypassed or absent (2 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 Boot or Logon Initialization Scripts by examining the target platforms (macOS, Windows, Linux).

2. Assess Existing Defenses: Review whether mitigations for T1037 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.
