Signatures

Multi AV Scanner detection for submitted file
Yara detected AgentTesla
Yara detected GuLoader
Detected RDTSC dummy instruction sequence (likely for instruction hammering)
Hides threads from debuggers
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Tries to detect Any.run
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to detect virtualization through RDTSC time measurements
Writes to foreign memory regions
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Creates a window with clipboard capturing capabilities
Detected potential crypto function
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
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)
Sample file is different than original file name gathered from version info
Tries to load missing DLLs
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara detected Credential Stealer
