SharpGmailC2 is a Command and Control (C2) tool that utilizes Gmail for exfiltrating data and receiving commands via SMTP and IMAP protocols. It allows users to send commands through unread emails while leveraging Gmail's infrastructure for stealthy operation, though it is noted that the tool is currently flagged by Windows Defender. This tool is designed for educational and testing purposes, enabling operators to manage remote implants over email while maintaining a relatively low detection profile.
