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
Internet Provider seen in connection with other malware
Detected potential crypto function
Found evasive API chain (may stop execution after checking a module file name)
JA3 SSL client fingerprint seen in connection with other malware
Contains functionality to dynamically determine API calls
HTTP GET or POST without a user agent
Program does not show much activity (idle)
IP address seen in connection with other malware
AV process strings found (often used to terminate AV products)
PE file contains an invalid checksum
Tries to load missing DLLs
Drops PE files to the windows directory (C:\Windows)
Checks if the current process is being debugged
