Signatures
Multi AV Scanner detection for dropped file
Contain functionality to detect virtual machines
Installs new ROOT certificates
Machine Learning detection for dropped file
PE file has a writeable .text section
PE file has nameless sections
Queries sensitive disk information (via WMI, Win32_DiskDrive, often done to detect virtual machines)
Queries sensitive sound device information (via WMI, Win32_SoundDevice, often done to detect virtual machines)
Writes many files with high entropy
Checks for debuggers (devices)
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 debugger is running (OutputDebugString,GetLastError)
Contains functionality to check if a window is minimized (may be used to check if an application is visible)
Contains functionality to communicate with device drivers
Contains functionality to delete services
Contains functionality to dynamically determine API calls
Contains functionality to query CPU information (cpuid)
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the PEB
Contains functionality to retrieve information about pressed keystrokes
Contains functionality to shutdown / reboot the system
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Creates or modifies windows services
Detected potential crypto function
Drops PE files
Drops files with a non-matching file extension (content does not match file extension)
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 dropped PE file which has not been started or loaded
Found evasive API chain (date check)
Found evasive API chain (may stop execution after checking a module file name)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
May sleep (evasive loops) to hinder dynamic analysis
Modifies existing windows services
PE file contains sections with non-standard names
Potential key logger detected (key state polling based)
Queries disk information (often used to detect virtual machines)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
Queries the product ID of Windows
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Stores files to the Windows start menu directory
Stores large binary data to the registry
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
