# T1124 System Time Discovery

## High-Level Description

An adversary may gather the system time and/or time zone settings from a local or remote system. The system time is set and stored by services, such as the Windows Time Service on Windows or <code>systemsetup</code> on macOS. These time settings may also be synchronized between systems and services in an enterprise network, typically accomplished with a network time server within a domain.

System time information may be gathered in a number of ways, such as with Net on Windows by performing <code>net time \\hostname</code> to gather the system time on a remote system. The victim's time zone may also be inferred from the current system time or gathered by using <code>w32tm /tz</code>. In addition, adversaries can discover device uptime through functions such as <code>GetTickCount()</code> to determine how long it has been since the system booted up.

On network devices, Network Device CLI commands such as `show clock detail` can be used to see the current time configuration. On ESXi servers, `esxcli system clock get` can be used for the same purpose.

In addition, system calls – such as <code>time()</code> – have been used to collect the current time on Linux devices. On macOS systems, adversaries may use commands such as <code>systemsetup -gettimezone</code> or <code>timeIntervalSinceNow</code> to gather current time zone information or current date and time.

This information could be useful for performing other techniques, such as executing a file with a Scheduled Task/Job, or to discover locality information based on time zone to assist in victim targeting (i.e. System Location Discovery). Adversaries may also use knowledge of system time as part of a time bomb, or delaying execution until a specified date/time.

## Kill Chain Phase

- Discovery (TA0007)

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

## What to Check

- [ ] Identify if System Time Discovery technique is applicable to target environment
- [ ] Check ESXi systems for indicators of System Time Discovery
- [ ] Check Linux systems for indicators of System Time Discovery
- [ ] Check macOS systems for indicators of System Time Discovery
- [ ] Assess detection coverage (1 detection strategies)

## How to Test

### Atomic Red Team Tests

The following tests are from [Atomic Red Team](https://github.com/redcanaryco/atomic-red-team) and provide actionable ways to test this technique:

### Atomic Test 1: System Time Discovery

Identify the system time. Upon execution, the local computer system time and timezone will be displayed.

**Supported Platforms:** windows

```cmd
net time \\#{computer_name}
w32tm /tz
```

### Atomic Test 2: System Time Discovery - PowerShell

Identify the system time via PowerShell. Upon execution, the system time will be displayed.

**Supported Platforms:** windows

```powershell
Get-Date
```

### Atomic Test 3: System Time Discovery in FreeBSD/macOS

Identify system time. Upon execution, the local computer system time and timezone will be displayed.

**Supported Platforms:** linux, macos

```bash
date
```

### Atomic Test 4: System Time Discovery W32tm as a Delay

identifies DCRat delay time tactics using w32tm.

https://blogs.blackberry.com/en/2022/05/dirty-deeds-done-dirt-cheap-russian-rat-offers-backdoor-bargains

**Supported Platforms:** windows

```cmd
W32tm /stripchart /computer:localhost /period:5 /dataonly /samples:2
```

### Atomic Test 5: System Time with Windows time Command

Displays the current system time via the Windows builtin time command: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/time
Recently observed in use in the wild during an incident involving Ursnif malware:

https://thedfirreport.com/2023/01/09/unwrapping-ursnifs-gifts/

**Supported Platforms:** windows

```cmd
time
```

### Manual Testing

If Atomic Red Team tests are not applicable, manually verify the technique by:

1. **Identify Attack Surface**: Determine if the target environment is susceptible to System Time Discovery by examining the target platforms (ESXi, Linux, macOS).

2. **Assess Existing Defenses**: Review whether mitigations for T1124 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.
