Replacing or modifying
firmware to insert malware or bypass security features. This is often done
via physical access (UART or JTAG, for example) or over-the-air (OTA)
updates.
Unauthorized code execution:
Exploiting bootloaders or
update mechanisms to run custom (unsigned) code.
Reverse engineering and IP theft:
Extracting firmware to
discover proprietary algorithms or cryptographic material.
Key extraction:
Reading secrets or signing
keys from insecure Flash, RAM or debugging interfaces.
Rollback attacks:
Reinstalling older,
vulnerable firmware versions that bypass security.
Supply chain attacks:
Compromising the device
before deployment (during manufacturing or transit, for example).
Side-channel and fault injection attacks:
Using physical methods (such
as glitching, voltage manipulation or EM analysis) to extract secrets or
disrupt normal execution.
Denial of Service (DoS):
Disrupting normal operation
by corrupting critical software or resources.
