Xbox 360 softmod?

I’ve been hearing about an Xbox 360 softmod that runs off a flash drive. I have an Xbox 360, and I have an iPhone, and an Android phone, and I have Macs, so it should be enough to put the softmod on a flash drive and stick it in the 360, right? Well, the instructions I’m finding (on various YouTube videos about it) all say I have to run a .EXE file (in Windows). The only access I have to Windows is at work, and we can’t bring flash drives in, or run executable files there (that aren’t approved). All this sounds real sketchy anyway. So, is there any truth to this softmod or are various YouTubers (none of them well known, trustworthy sources) just trying to get people to install ransomware on Windows machines? Is there an actual package that can simply be extracted to the flash drive? Just wondering if anyone here knows anything about it.
