Introduction
SPTD (SCSI Pass Through Direct) is a SCSI virtual drive applied to DAEMON TOOLS 4.x and above (Alcohol also uses this driver 120%) The program (in layman's terms, is to intercept the read request of the virtual CD-ROM inside the system and boot to the user-specified image file, but the driver can also be used for general purposes). The driver was developed by Duplex Secure Co, Ltd. and does not provide source code.

Working Mechanism:
The driver (drive file name is sptd.sys) takes the same technology as the notorious Rootkit (a Trojan horse implant). After installation, it will modify the underlying system. The database (that is, the security account manager SAM data, and the privileged key values ​​in the registry) to protect yourself from interference (not visible to the operating system and other programs, this is a good way to disguise the virtual CD-ROM and its loaded image files) Therefore, it often causes false positives of anti-virus software and anti-hacking software (such as Symantec Antivirus and RootkitRevaler). At the same time, the driver is not compatible with any kernel mode debugger (WinDBG, SoftICE, etc.). The SPTD gives priority to controlling the underlying hardware of the system when the program is called, and then passes control to the calling program.
