The PSP also provides a random number generator for the RDRAND instruction and provides TPM services. They discovered that the firmware is run inside in the same system's memory space that user's applications do with unrestricted access to it (including MMIO) raising concerns over data safety. Investigation of a Lenovo ThinkPad A285 notebook's motherboard flash chip (stores UEFI firmware) revealed that the PSP core itself (as a device) is run before the main CPU and that its firmware bootstrapping process starts just before basic UEFI gets loaded.
By using a few hand-written Python-based tools, they found that the off-chip firmware from the SPI ROM contained an application resembling an entire micro operating system.

In 2019, a Berlin based security group discovered the off-chip firmware in ordinary UEFI image files (the code that boots up the operating system), which meant that it could be easily analyzed. The PSP contains on-chip firmware which is responsible for verifying the SPI ROM and loading off-chip firmware from it.
