Office equation editor drops PE file
Office equation editor starts processes (likely CVE 2017-11882 or CVE-2018-0802)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)

Sigma detected: Executables Started in Suspicious Folder
Sigma detected: Execution in Non-Executable Folder
Sigma detected: Suspicious Program Location Process Starts
Allocates memory within range which is reserved for system DLLs (kernel32.dll, advapi32.dll, etc)
Contains functionality for read data from the clipboard
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a window is minimized (may be used to check if an application is visible)
Contains functionality to check the parent process ID (often done to detect debuggers and analysis systems)
Contains functionality to detect sandboxes (mouse cursor move detection)
Contains functionality to dynamically determine API calls
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the clipboard data
Contains functionality to record screenshots
Contains functionality to retrieve information about pressed keystrokes
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates a window with clipboard capturing capabilities
Detected potential crypto function
Downloads executable code via HTTP
Drops PE files
Drops PE files to the user directory
Enables debug privileges
Extensive use of GetProcAddress (often used to hide API calls)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found inlined nop instructions (likely shell or obfuscated code)
Found potential string decryption / allocating functions
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May check if the current machine is a sandbox (GetTickCount - Sleep)
May sleep (evasive loops) to hinder dynamic analysis
Office Equation Editor has been started
PE file contains strange resources
Potential document exploit detected (performs DNS queries)
Potential document exploit detected (performs HTTP gets)
Potential document exploit detected (unknown TCP traffic)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
