Security researchers have documented serious exploits involving modified serial port drivers. In one documented case, an unsigned VSPD driver on an unpatched Windows 10 workstation was hijacked by a malicious DLL injection. The attacker manipulated the driver's ACL settings to D:P(A;;GA;;;WD) , which granted "Everyone" full control. A regular domain user process then obtained the device handle through CreateFile("\\\\.\\COM7", ...) and cleared the entire FIFO buffer—a textbook kernel-level serial port hijacking attack.
By version 9.0 and later, the software evolved even further, adding capabilities like splitting real ports, redirecting serial traffic, merging multiple real ports into one virtual port, and sharing real ports among multiple applications. The current versions (now reaching version 11.0+) include features such as loopback port bundles, automatic port switching, command-line interface support, and complex bundle management.
