This bug was also called moonshine in the beginning
Basically the following bug is present in all bootroms I have looked at:
1. When usb is started to get an image over dfu, dfu registers an interface to handle all the commands and allocates a buffer for input and output
2. if you send data to dfu the setup packet is handled by the main code which then calls out to the interface code
3. the interface code verifies that wLength is shorter than the input output buffer length and if that's the case it updates a pointer passed as an argument with a pointer to the input output buffer
4. it then returns wLength which is the length it wants to recieve into the buffer
5. the usb main code then updates a global var with the length and gets ready to recieve the data packages
6. if a data package is recieved it gets written to the input output buffer via the pointer which was passed as an argument and another global variable is used to keep track of how many bytes were recieved already
7. if all the data was recieved th

Hello reddit. Today, I'm going to be reverse engineering the Blackmart app. In case you don't know, Blackmart is an alternative Android app store which allows you to download paid apps for free.

###Redirecting and capturing the traffic### First of all, I will need to redirect the traffic of my tablet to my computer so I can use Wireshark to look at the data. To do this, I use LANS.py. It is a small python script which allows you to do MITM attacks.

LANS.py also shows you the URLs of the pages used by an app. It really helps with reverse-engineering APIs.

After redirecting the traffic to my computer and starting Wireshark, I run the Blackmart app, look at the recent apps section, do 2 searches for terraria and chronometer and download a chronometer app.

After doing these, I stop the capture, save it and start looking at the data.
