Can firmware be hacked?

The research we referenced at the beginning of this article showed that Firmware could be hacked and embedded with malware. … Since the firmware isn’t secured by a cryptographic signature, it won’t detect the infiltration, and the malware will be hidden within the firmware code.

Is it safe to update firmware?

In which language firmware is written?

That is to say, firmware is typically written in a low level language (be it C or assembly), compiled and assembled into machine code, and placed in a known position on this storage, where the hardware, during its startup process can read from a known location, and begin executing that machine code.
