Tries to steal Crypto Currency Wallets
Writes to foreign memory regions
AV process strings found (often used to terminate AV products)
Allocates memory with a write watch (potentially for evading sandboxes)
Binary contains a suspicious time stamp

HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, 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
Searches for user specific document files
Sigma detected: Dynamic .NET Compilation Via Csc.EXE
Suricata IDS alerts with low severity for network traffic
