There are two other attacks for stm i know off
DFU attack where you read back using DFU commands and a USB overflow, works with hardware DFU or software DFU based off STM implementation.
Vector table attack where you read flash then reset to a vector and read that byte.
there is a third attack but I dont think it works on the F2 series and thats the boot from ram attack.
