Though I have been critical of LLMs in general, I have to give them credit for being really good digging out stuff that me as a human would find tedious. As such, I have my own LOCAL clanker that I use for two things: as a rubber duck and dump an apk with apktool inside a locked up container and let it go nuts. I've done it on numerous popular apps and it has found countless hardcoded credentials and keys in them. Just about all apps really, so far I think there's only been one that hasn't had THIS particular problem(it did have countless others though).
