Security researchers recently discovered that forcing a System Management Interrupt during the EFI password prompt can dump the SMM (System Management Mode) memory, revealing the plaintext password. Tools like UEFI SMM PwDump exist, but they require booting from an external SPI programmer or a malicious PCIe device. This is currently the for 2025 laptops, but impractical for everyday users.
