Есть ли способ внедрить код javascript на веб-сайт и внести в него изменения без использования расширений, таких как tamperedmonkey?

Hello, I'm trying to inject a script into the victim's binance account where the amount of money he has in his balance will be changed and no matter if he updates the fake amount, it will still be there even if he logs out, i did it using tamperedmoneky but the victim knows about this trick, can you suggest me another way to do it without using extensions?
