Rival tools can easily cost 20x more.

… "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." …

The people in this community hope for a world where an individual’s informational footprints—everything from an opinion on abortion to the medical record of an actual abortion—can be traced only if the individual involved chooses to reveal them; a world where coherent messages shoot around the globe by network and microwave, but intruders and feds trying to pluck them out of the vapor find only gibberish; a world where the tools of prying are transformed into the instruments of privacy. There is only one way this vision will materialize, and that is by widespread use of cryptography. Is this technologically possible? Definitely. The obstacles are political—some of the most powerful forces in government are devoted to the control of these tools. In short, there is a war going on between those who would liberate crypto and those who would suppress it. The seemingly innocuous bunch strewn around this community represents the vanguard of the pro-crypto forces. Though the battleground seems remote, the stakes are not: The outcome of this struggle may determine the amount of freedom our society will grant us in the 21st century. To the Cypherpunks, freedom is an issue worth some risk.
