Something about this just strikes me as arrogant. Please enlighten me if I misunderstood ...

"How does it work?

We communicate with Snapchat's servers and pretend to be their mobile app. This gives us access to everything that you can do through the mobile app. For example, we can send messages, view (and save) messages, create new accounts..."

That's a detail that's not relevant at all to their "users" (the people sending in snapchats). It sounds like they're bragging about their circumvention of Snapchat's lack of an API.

I don't want to diminish the technical accomplishment here -- reverse an engineering an API and writing a Snapchat bot is impressive. But, as other posters have pointed out, they're likely violating the Snapchat terms and misleading their "users."

Is it impressive? Unless Snapchat put a lot of work into making the binaries prevent RE (which, in ios is probably unlikely due to runtime restrictions), it's probably fairly straightforward.

On another note, the only way an app dev could really prevent this is if mobile devices had some sort of TPM or other remote attestation feature.

Thanks for the feedback. Fixing it now.
