it's one of my projects: https://github.com/supertestnet/breaker-of-jpegs/

I used it to take down Unisat's inscription explorer for a day, and I also introduced an off-by-one bug into the explorer at ordinals.com that took them a few months to fix (because fixing it meant changing people's inscription numbers)

See this github issue for more details: https://github.com/ordinals/ord/issues/2062
