Today we will be looking at the firmware that we extracted from the last post (https://dfresh.ninja/index.php/2021/01/16/exploring-uart-protocol-and-dumping-firmware-on-the-tenda-300-wireless-router/). Last time we were able to extract files called BSS, CFEMenu, Data, Heap, Stack, and Text. Let’s see what kinds of files these are. I downloaded these files into a Linux virtual machine, because I am more used to READ MORE

Exploring UART Protocol and Dumping Firmware on the Tenda 300 Wireless Router
In our initial post we opened up the Tenda Wireless N300 router. We were able to successfully connect to the UART protocol using a USB to TTY serial cable. We brute forced the baud rate and then used putty to gain access to the device. This time around we are going to look at what READ MORE
Tenda Router IoT Hacking
Today we are going to take apart an old router and see what the insides look like. Then hopefully we will find something like JTAG or UART that we can connect to over USB and read some data off the router. JTAG, named from the Joint Test Action Group, is used for computer interaction with READ MORE
