… “The first of two versions of the RayV Lite will focus on laser fault
injection (LFI). This technique uses a brief blast of light to interfere with
the charges of a processor’s transistors, which could flip them from a 0 value
to a 1 value or vice versa. Using LFI, Beaumont and Trowell have been able to
pull off things like bypassing the security check in an automotive chip’s
firmware or bypassing the PIN verification for a cryptocurrency hardware wallet.
The second version of the tool will be able to perform laser logic state
imaging. This allows snooping on what’s happening inside a chip as it operates,
potentially pulling out hints about the data and code it’s handling. Since this
data could include sensitive secrets, LSI is another dangerous form of hacking
that Beaumont and Trowell hope to raise awareness of.” …
