Machine Learning detection for dropped file
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Uses schtasks.exe or at.exe to add and modify task schedules
Tries to harvest and steal browser information (history, passwords, etc)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
Yara detected Credential Stealer
JA3 SSL client fingerprint seen in connection with other malware
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Contains long sleeps (>= 3 min)
Enables debug privileges
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)
Sample file is different than original file name gathered from version info
Drops PE files
Uses a known web browser user agent for HTTP communication
Contains capabilities to detect virtual machines
Creates a window with clipboard capturing capabilities
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
