T1082 - System Information Discovery

Description from ATT&CK

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 the information from [System Information Discovery](https://attack.mitre.org/techniques/T1082) during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.

Tools such as Systeminfo can be used to gather detailed system information. A breakdown of system data can also be gathered through the macOS systemsetup command, but it requires administrative privileges.

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)

Atomic Tests


Atomic Test #1 - System Information Discovery

Identify System Info. Upon execution, system info and time info will be displayed.

Supported Platforms: Windows

Attack Commands: Run with command_prompt!

systeminfo
reg query HKLM\SYSTEM\CurrentControlSet\Services\Disk\Enum


Atomic Test #2 - System Information Discovery

Identify System Info

Supported Platforms: macOS

Attack Commands: Run with sh!

system_profiler
ls -al /Applications


Atomic Test #3 - List OS Information

Identify System Info

Supported Platforms: Linux, macOS

Inputs:

Name Description Type Default Value
output_file Output file used to store the results. path /tmp/T1082.txt

Attack Commands: Run with sh!

uname -a >> #{output_file}
if [ -f /etc/lsb-release ]; then cat /etc/lsb-release >> #{output_file}; fi;
if [ -f /etc/redhat-release ]; then cat /etc/redhat-release >> #{output_file}; fi;      
if [ -f /etc/issue ]; then cat /etc/issue >> #{output_file}; fi;
uptime >> #{output_file}
cat #{output_file} 2>/dev/null

Cleanup Commands:

rm #{output_file} 2>/dev/null


Atomic Test #4 - Linux VM Check via Hardware

Identify virtual machine hardware. This technique is used by the Pupy RAT and other malware.

Supported Platforms: Linux

Attack Commands: Run with bash!

if [ -f /sys/class/dmi/id/bios_version ]; then cat /sys/class/dmi/id/bios_version | grep -i amazon; fi;
if [ -f /sys/class/dmi/id/product_name ]; then cat /sys/class/dmi/id/product_name | grep -i "Droplet\|HVM\|VirtualBox\|VMware"; fi;
if [ -f /sys/class/dmi/id/product_name ]; then cat /sys/class/dmi/id/chassis_vendor | grep -i "Xen\|Bochs\|QEMU"; fi;
if [ -x "$(command -v dmidecode)" ]; then sudo dmidecode | grep -i "microsoft\|vmware\|virtualbox\|quemu\|domu"; fi;
if [ -f /proc/scsi/scsi ]; then cat /proc/scsi/scsi | grep -i "vmware\|vbox"; fi;
if [ -f /proc/ide/hd0/model ]; then cat /proc/ide/hd0/model | grep -i "vmware\|vbox\|qemu\|virtual"; fi;
if [ -x "$(command -v lspci)" ]; then sudo lspci | grep -i "vmware\|virtualbox"; fi;
if [ -x "$(command -v lscpu)" ]; then sudo lscpu | grep -i "Xen\|KVM\|Microsoft"; fi;


Atomic Test #5 - Linux VM Check via Kernel Modules

Identify virtual machine guest kernel modules. This technique is used by the Pupy RAT and other malware.

sudo lsmod | grep -i "hv_vmbus\|hv_blkvsc\|hv_netvsc\|hv_utils\|hv_storvsc"


Atomic Test #6 - Hostname Discovery (Windows)

Identify system hostname for Windows. Upon execution, the hostname of the device will be displayed.

Supported Platforms: Windows

Attack Commands: Run with command_prompt!

hostname


Atomic Test #7 - Hostname Discovery

Identify system hostname for Linux and macOS systems.

Supported Platforms: Linux, macOS

Attack Commands: Run with bash!

hostname


Atomic Test #8 - Windows MachineGUID Discovery

Identify the Windows MachineGUID value for a system. Upon execution, the machine GUID will be displayed from registry.

Supported Platforms: Windows

Attack Commands: Run with command_prompt!

REG QUERY HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography /v MachineGuid


Atomic Test #9 - Griffon Recon

Griffon is a sophisticated tool believed to be in use by one of more "APT" groups. This atomic is for detecting, specifically, the reconnaissance part of the tool. This script used here was reduced by security researcher Kirk Sayre (github.com/kirk-sayre-work/1a9476e7708ed650508f9fb5adfbad9d), and it gives the exact same recon behavior as the original (minus the C2 interaction).
For more information see also e.g. https://malpedia.caad.fkie.fraunhofer.de/details/js.griffon and https://attack.mitre.org/software/S0417/

Supported Platforms: Windows

Inputs:

Name Description Type Default Value
vbscript Path to sample script String PathToAtomicsFolder\T1595.002\src\griffon_recon.vbs
