In terms of fault injection as a security attack vector (vs. just a test vector, where it of course dates back to the beginning of computing) in general, satellite TV cards were attacked with clock glitching at least dating back into the 1990s, like the "unlooper" (1997). There were also numerous attacks against various software RSA implementations that relied on brownout or crowbar glitching like this - I found https://ieeexplore.ieee.org/document/5412860 right off the bat but I remember using these techniques before then.
