HACK AND CLONE CAR KEY FOB, MY EPIC FAILURE...!!

-

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 guide will walk you through the steps of resolving the kernel panic error that you may encounter after upgrading your Parrot OS kernel to version 5.6.0. Step 1: Enter Recovery Mode Restart your computer and enter the GRUB menu by pressing the appropriate key during the boot process. The specific key may vary depending on your computer's manufacturer and BIOS settings. Common keys include F2, F10, Delete, or Esc. Once in the GRUB menu, select "Advanced Mode" using the arrow keys and press Enter. In the Advanced Mode menu, locate the entry for Parrot OS 6.1 and select "Recovery Mode" using the arrow keys. Press Enter to boot into Recovery Mode. Step 2: Purge Problematic Packages Once in Recovery Mode, log in as root using the default credentials. Open a terminal window by selecting "Drop to root shell prompt" from the Recovery Mode menu. ...

secrets of arduino atmega328p adc

In this tutorials i'm gonna tell you all about the adc present in arduino famous boards like UNO,NANO,MINI....the atmega328p chips consist of the " 10-bit resolution adc " inside the uC. The type of adc is used in is  Successive approximation ADC . these are kind are slow but gives good resolution though. let's dig in registers of adc in atmega328p. To read analog input we need The reg " ADMUX ". T he adc reg have a Pin called AREF (adc reference voltage). The gives 10-bit number i.e 0-1023, 0-0V & 1023-5V. it measures using this formula       Vin = (Analog Ref * analogRead() ) / 1024 we need stable AREF voltage we can use internal 1.1V reference or we need to provide a stable voltage anywhere between 0.3V-5V externally. [NOTE: if ur are planning to provide external voltage to aref pin present on arduino uno,nano,mini, the recommended value is less than 5v to be safe on safe side cause the voltage of external 5v source may not be 5v exactly so if it i...
