Very long cmdline option found, this is very uncommon (may be encrypted or packed)
Deletes files inside the Windows folder
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Creates files inside the system directory
Detected potential crypto function
Contains functionality to query CPU information (cpuid)
Found potential string decryption / allocating functions
Sample execution stops while process was sleeping (likely an evasion)
JA3 SSL client fingerprint seen in connection with other malware

Checks if the current process is being debugged
Enables security privileges
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Uses Microsoft's Enhanced Cryptographic Provider
Creates a process in suspended mode (likely to inject code)
