MavLink telemetry to FrSky Taranis using a Teensy converter
Recently I wanted to have sensors values from ArduPilot back into FrSky Taranis radio,
mostly to be able to see my quadcopter's current altitude and GPS ground speed.
The goal is to have a nice real time display of telemetry sensors on Taranis LCD screen.
My quadcopter current setup is:
- Flight Controller: HobbyKing APM 2.7
- Running ArduCopter 3.2
- Radio Tx: FrSky Taranis X9D
- Running OpenTx 2.1.8
- Receiver: FrSky X8R (S-Port)
Solution to Codegate 2012 Net100
Challenge (with Big-Daddy team) :
Someone has leaked very important documents. We couldn't find any proof without one PCAP file. But this file was damaged.
The password of disclosure document is very weakness and based on Time, can be found easily.
Cryptographic algorithm is below.
Msg = "ThisIsNotARealEncryption!SeemToEncoding"
Key = 0x20120224 (if date format is 2012/02/24 00:01:01)
Cryto = C(M) = Msg * Key = 0xa92fd3a82cb4eb2ad323d795322c34f2d809f78
Answer: Decrypt(Msg)

About one year ago, I submitted on crackmes.de this solution to the keygenme xc2 made by Virw. Unfortunately, crackmes.de has been down for months by now, so I guess there is no harm to put both the challenge and the solution on this blog.
Keywords: keygen, windows, crc32.

Shellify is a little bash script designed to help programming shellcodes. All it does is basically compiling your asm file using nasm, and then converting it to an hexadecimal representation.
You probably already own such a tool, and if you don't, then you should !

The challenges section is empty for now.
I am currently working on a few - hopefully - interesting challs, so expect to find crackmes and network related stuff in the future.
