TM17 is a wrong pocket TM in Pokémon Gold and Silver. Its description is "Foils attack that turn. It may fail.".


TM17 causes arbitrary code execution at FA47 in Echo RAM (a copy of DA47 in WRAM). This data is in the middle of party Pokémon 1's data, making it an ideal arbitrary code execution item.
