Read and modify packets

[HPWebcamAble]

TLDR I want to modify packets being sent from and to my iPhone (through my own router) using my computer (wired to the router)

 

I'm looking for a program that can read, modify, and create packets being set over wifi to and from my iPhone (6, if that matters).

I image it would have to happen from my computer, which is plugged into the router.

 

Anyone know of a program that can do this?

It would be great if it's simple to use, I'm a newb when it comes to networking

modifying packets.....on the fly?

 

Can I ask what you're doing?

Basically, trying to get in-game credits for an app on my phone.

Does this sound extreme? Yes, yes it does. But that's another story.

wireshark can do that if the packets are going to and from your PC

but if theyre going to and from your phone the i dont think thats possible unless you have some l33t hacker skillz and can code some custom firmware for your router or something

Yeah I don't think it would be possible to spoof in game credits. I would bet since it's relying on a server connection that there's going to be some kind of verification on the server side regarding how many credits you have. 

 

Also @Enderman has a point. A program that edits packets on your local machine is fancy enough, but tricking your iPhone into thinking it's receiving the correct data is a bit of a long shot.

I THINK wireshark can edit traffic on your router as well, but I wanted to see if anyone knew of a better way. I'll look into it.

It does not. Why? I'm not entirely sure, but I believe it's because the game was made to be completely single player, and when logins were added (for saving your data and logging into multiplayer), the devs were to lazy to modify the base game, and instead just have it report your save data periodically.

 

I could either

• trick the phone into thinking a new save is available, which has more credits
• trick the server into thinking I got a ton of credits while offline, then log in again on my phone to update the game

The other option is editing the game's save data on my phone, but since iOS 8.3, developers can disable itunes file sharing, which means the only way to access the game's files are by jail breaking my phone, which I don't want to do.

Update @ShadyHost @Enderman

 

So wireshark does pick up some packets going from my phone, but none going to the games servers. They all go to IP multicast addresses (Those starting with 224 and 239, according to this page: http://who.is/whois-ip/ip-address/224.0.0.251 ), and I don't think the game I'm targeting is initiating them.

 

Perhaps my laptop will be able to read all traffic? The computer I just tried it on was a desktop with no Wifi adapter.
