From Concept to Bench - Designing a Flipper-compatible nRF24L01 RF Module for Security Research

    Six months of design iterations, sourcing headaches, and a broken oscilloscope later — I am pleased to share a hardware module I designed to extend the Flipper ecosystem for RF security research. This write-up covers the motivation, engineering challenges, capabilities, and responsible-disclosure principles behind the project — and a frank look at a vulnerability that is very much alive in the Maldives today.   Left: 3D render of final PCB     ·     Right: Altium Designer PCB layout view Why I Built It  The trigger was reading the original MouseJack disclosure by Bastille Networks. It made me realize that a class of peripherals most people assume to be harmless — the cheap wireless mouse on your desk — can be weaponized from a car park. I wanted a research platform small enough to carry in a jacket pocket, native to the Flipper Zero ecosystem, and capable of passive scanning, protocol analysis, and controlled lab tests. What I...

GSM Remote














Its been few days that i was trying to get a damage mobile phone, any model is fine for the purpose that i need. Luckily i got a NOKIA 1100, which is an old series of nokia. The phone was in a terrible condition. I mean it was taken from water and some parts of the PCB was getting corroded.

I did some clean up work and wala.. it was well cleaned enough. So i did some research on the nokia 1100 PCB and connected the voltage links and gave 4V and it was on but nothing on the screen. screen is damage, which i don't need later but at start i need it so i fixed and put my SIM and it appears NO SIM INSERTED.. so i did fix that problem and wala.. the phone works fine.

Tonight i will take some pictures of it and post it here.. next step is little hard but will try it. Tonight nokia MBUS/FBUS will be wired and interface to my Laptop for further investigations..keke so keep on peeping.

Did you get a chance to work on this? I'm trying to do something simliar to what you're doing. Maybe we can help each other. I built the MBUS/FBUS cable and tested it with software off the internet and I was able to put the 1100 in test mode, make it ring, and make it vibrate. Now I want to be able to interface with it using a microcontroller like a PIC.

SIMCOM SIM900A fixed

Since everyone is interested in this post and lots of request comes to get the firmware, i have put a link so that everyone can download it easily. SIMCOM 900A firmware Its been a while that i was trying to fix the SIM900A GSM module. This module support local GSM band but after some researches it was concluded that it is carrier locked :(. After long conversion of days to actual chip manufacture SIMCOM, they told it can be fixed by updating its firmware to latest original version but unfortunately they don't provide firmware to small parties. I never stop trying to get the firmware and SIMCOM again replied, this time they said contact local SIMCOM supplier and request for firmware. But this little Maldives don't have SIMCOM or any electronics manufacturer. So i contacted my friend coody from NOA LABS/Smart prototyping (a friend in china) and told him to help me. I explained him what to do so he can communicate with SIMCOM in china. Finally he sends and email saying that...

Clover Display M302 hack

Its been a while i have this LCD and today i thought of connecting the LCD display to Arduino. Unfortunately i could not found any pin outs of this from any where and from the manufacture. Actually this is very old model which i got from old FAX machine and this display is a very cheap from online sources. Clover Display M302 PCB Ver 1.0 (16x2) which has 10 pin flat cable. After researching for a while from the internet i have seen in many forums people are asking for help on how to connect it and what is the pin configurations? so i thought of helping them as well as my self at the same time. After going through some of my old collections of Russian data of displays and things i found a basic diagram of how 10 pin LCD display configuration.  PIN1   - VSS PIN2   - VDD PIN3   - CONTRAST PIN4   - RS PIN5   - R/W PIN6   - ENABLE PIN7   - DB4 PIN8   - DB5 PIN9   - DB6 PIN10 - DB7 I tried these configuration...

How to setup 2FA On Linux SSH Login

  This is a simple setup guide to enabling Two Factor Authentication (2FA) on Linux SSH login. I this article I wont go deep into setup and issues that I have faced when implementing this. First thing is first Update your system first. I have used Ubuntu 20.04 and it is always up to date. To enable 2FA you need to install google authenticator modules sudo apt install libpam-google-authenticator Configuration for PAM and SSHD Add the the following line to /etc/pam.d/sshd and After adding this line please restart the sshd services.  auth required pam_google_authenticator.so Go to /etc/ssh/sshd_config and check if the following line exist. Default value will be "no" so change it to "yes" to activate.  ChallengeResponseAuthentication yes Configuration for Authenticator In the terminal run google authenticator command It will ask few things to acknowledge by user. Details you can see from the below video. Once this part is done you are ready to use the 2FA in ubuntu. T...
