EXPLORE DETECTIONS
Sysprep on AppData Folder
Detects suspicious sysprep process start with AppData folder as target (as used by Trojan Syndicasec in Thrip report by Symantec)
System and Hardware Information Discovery
Detects system information discovery commands
System Control Panel Item Loaded From Uncommon Location
Detects image load events of system control panel items (.cpl) from uncommon or non-system locations that may indicate DLL sideloading or other abuse techniques.
System Disk And Volume Reconnaissance Via Wmic.EXE
An adversary might use WMI to discover information about the system, such as the volume name, size, free space, and other disk information. This can be done using the 'wmic' command-line utility and has been observed being used by threat actors such as Volt Typhoon.
System Drawing DLL Load
Detects processes loading "System.Drawing.ni.dll". This could be an indicator of potential Screen Capture.
System File Execution Location Anomaly
Detects the execution of a Windows system binary that is usually located in the system folder from an uncommon location.
System Info Discovery via Sysinfo Syscall
Detects use of the sysinfo system call in Linux, which provides a snapshot of key system statistics such as uptime, load averages, memory usage, and the number of running processes. Malware or reconnaissance tools might leverage sysinfo to fingerprint the system - gathering data to determine if it's a viable target.
System Information Discovery
Detects system information discovery commands
System Information Discovery - Auditd
Detects System Information Discovery commands
System Information Discovery Using Ioreg
Detects the use of "ioreg" which will show I/O Kit registry information. This process is used for system information discovery. It has been observed in-the-wild by calling this process directly or using bash and grep to look for specific strings.
System Information Discovery Using sw_vers
Detects the use of "sw_vers" for system information discovery
System Information Discovery Using System_Profiler
Detects the execution of "system_profiler" with specific "Data Types" that have been seen being used by threat actors and malware. It provides system hardware and software configuration information. This process is primarily used for system information discovery. However, "system_profiler" can also be used to determine if virtualization software is being run for defense evasion purposes.
System Information Discovery via Registry Queries
Detects attempts to query system information directly from the Windows Registry.
System Information Discovery Via Sysctl - MacOS
Detects the execution of "sysctl" with specific arguments that have been used by threat actors and malware. It provides system hardware information. This process is primarily used to detect and avoid virtualization and analysis environments.
System Information Discovery Via Wmic.EXE
Detects the use of the WMI command-line (WMIC) utility to identify and display various system information, including OS, CPU, GPU, disk drive names, memory capacity, display resolution, baseboard, BIOS, and GPU driver products/versions.
System Integrity Protection (SIP) Disabled
Detects the use of csrutil to disable the Configure System Integrity Protection (SIP). This technique is used in post-exploit scenarios.
System Integrity Protection (SIP) Enumeration
Detects the use of csrutil to view the Configure System Integrity Protection (SIP) status. This technique is used in post-exploit scenarios.
System Language Discovery via Reg.Exe
Detects the usage of Reg.Exe to query system language settings. Attackers may discover the system language to determine the geographic location of victims, customize payloads for specific regions, or avoid targeting certain locales to evade detection.
System Network Connections Discovery - Linux
Detects usage of system utilities to discover system network connections
System Network Connections Discovery - MacOs
Detects usage of system utilities to discover system network connections
System Network Connections Discovery Via Net.EXE
Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.
System Network Discovery - Linux
Detects enumeration of local network configuration
System Network Discovery - macOS
Detects enumeration of local network configuration
System Owner or User Discovery - Linux
Detects the execution of host or user discovery utilities such as "whoami", "hostname", "id", etc. Adversaries may use the information from System Owner/User Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
