Query: mitigate System Information Discovery
Matching passage: T1082 System Information Discovery. Tactics: discovery. Description: An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use this information to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions. This behavior is distinct from [Local Storage Discovery](https://attack.mitre.org/techniques/T1680) which is an adversary's discovery of local drive, disks and/or volumes. Tools such as [Systeminfo](https://attack.mitre.org/software/S0096) can be used to gather detailed system information. If running with privileged access, a breakdown of system data can be gathered through the <code>systemsetup</code> configuration tool on macOS. Adversaries may leverage a [Network Device CLI](https://attack.mitre.org/techniques/T1059/008) on network devices to gather detailed system information (e.g. <code>show version</code>).(Citation: US-CERT-TA18-106A) On ESXi servers, threat actors may gather system information from various esxcli utilities, such as `system hostname get` and `system version get`.(Citation: Crowdstrike Hypervisor Jackpotting Pt 2 2021)(Citation: Varonis) Infrastructure as a Service (IaaS) cloud providers such as AWS, GCP, and Azure allow access to instance and virtual machine information via APIs. Successful authenticated API calls can return data such as the operating system platform and status of a particular instance or the model view of a virtual machine.(Citation: Amazon Describe Instance)(Citation: Google Instances Resource)(Citation: Microsoft Virutal Machine API) [System Information Discovery](https://attack.mitre.org/techniques/T1082) combined with information gathered from other forms of discovery and reconnaissance can drive payload development and concealment.(Citation: OSX.FairyTale)(Citation: 20 macOS Common Tools and Techniques)
Near-miss passage: T1124 System Time Discovery. Tactics: discovery. 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.(Citation: MSDN System Time)(Citation: Technet Windows Time Service)(Citation: systemsetup mac time) 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.(Citation: Mac Time Sync)(Citation: linux system time) System time information may be gathered in a number of ways, such as with [Net](https://attack.mitre.org/software/S0039) 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>.(Citation: Technet Windows Time Service) 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.(Citation: Virtualization/Sandbox Evasion) On network devices, [Network Device CLI](https://attack.mitre.org/techniques/T1059/008) commands such as `show clock detail` can be used to see the current time configuration.(Citation: show_clock_detail_cisco_cmd) 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.(Citation: MAGNET GOBLIN) 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.(Citation: System Information Discovery Technique)(Citation: ESET DazzleSpy Jan 2022) This information could be useful for performing other techniques, such as executing a file with a [Scheduled Task/Job](https://attack.mitre.org
