YoNTMA (You'll Never Take Me Alive!) is a tool designed to enhance the protection of data encryption on laptops. YoNTMA runs as a status bar icon on FileVault-protected laptops. If the laptop is disconnected from AC power or wired Ethernet while the screen is locked, YoNTMA puts the system into hibernate. This prevents a laptop thief from accessing your encrypted data later via a DMA attack while the machine is still powered on and the encryption keys are in memory, and reduces the threat of a similar-style cold-boot attack.
