Signatures
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for submitted file
Adds a directory exclusion to Windows Defender
Machine Learning detection for sample
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Binary contains a suspicious time stamp
Contains capabilities to detect virtual machines
Contains functionality to dynamically determine API calls
Contains functionality to launch a program with higher privileges
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
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 potential string decryption / allocating functions
HTTP GET or POST without a user agent
IP address seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
PE / OLE file has an invalid certificate
PE file contains strange resources
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Uses code obfuscation techniques (call, push, ret)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
