FAIL AND LEARN

In this blog post i'm sharing my experience on cloning the my car key fob signal and how to do it properly. first things frist the cars now a days comes with a wireless remote key where u get atleast 2 or 3 options like lock,unlocking ,trunk(we call it as dickey!!!).....these options let your car access wirelessly and some cars are completly keyless for even driving. the keys of the cars are actually communicating with certain frequency like 433.xxxMHz or some countries uses 315.xxxMHz...the car companies uses an algorithm called " ROLLING CODES "...these are not that esay to crack cause they change every time u press key and once the key transmitted it cannot be used again... but a hacker named "samy kamakar" demonstrated an attack called REPLAY ATTACK where u simply transmitt the signal by recording the key fob away from car or blocking the signal and then recording. so this is how i've tried it..frist i needed to listen to the signals as possible in 10KHz

This post helps you to change the firmware of the hc05 Bluetooth chip into hid enabled Bluetooth chip. The HID stands for “HUMAN INTERFACE DEVICES” means things like your keyboard, mouse, printer, joysticks, etc.. Drivers get automatically installed in your computer without any external drivers needed.   The hc05 default don’t have hid capability but, the chip hc05 uses is same clone of chip RN-42 uses (BC417) , the RN-42 is an HID enabled chip. We gonna swap the firmware’s of rn42 into hc05. [NOTE: this particular hc05 chip comes with serial interface in it if you perform this swap it no longer work as serial Bluetooth chip. If you want you can save the firmware of hc05 and re-swap again to work normal]. That being said what are the things we need to perform this task are: 1.   HC05 module for sure (duh!) 2.   RN-42 chip {Wait if you are performing this task you must be very enthusiastic in electronics or extremely poor then why the hell you gonna buy an rn42 chip for..

the sdr is a cool gadget which can simulate the functioning of a radio transceiver the sdr a built in functionalities to do more things like building your own fm/am modulation stations virutally..... the sdr is also used to hack stuff life private walkie talkies and wireless rf transmitters and more i'll be posting some of awsome links to youtube channels about the sdr and how to get started with the sdr and more once u learn how to use u can do some cool stuff with it.... here are the link for sammy kramer hacking with sdr link for ossmann sdr tutorials
