THE TRICK IS OUT AND MAKE USE OF IT WHILE IT LASTS……THIS HOW YOU CAN NOW MAKE YOUR SAFARICOM AIRTIME USING AN ALREADY USED CARD,!

 

Almost two years ago, Safaricom Ltd extended the scratch card code from 12 digits to 16 in-order to increase the computational time required to break the code thereby making them more secure. However, system theory acknowledges that systems expose their weaknesses at points of change. I set to find out if the move to higher dimensionality introduced a weakness in the scratch card hidden reload number. To begin the analysis I formulated the following assumptions to guide me in the process.

  • The grouping of the hidden reload number into four digits does not reveal the mechanics of the number generator.
  • Increasing the hidden reload number by a factor of four digits provides more data for statistical analysis.
  • The hidden reload numbers are separated into groups of four digits only for the purposes of ease of reading.
  • The hidden reload number represents a 16 digit number generated by a random number generator.
  • With the assumptions in place I set to curate the data set, my collection of scratch cards came in handy (448 in number). In understanding each digit has relevance with its position, I created a data set with 16 variables each holding the positional value of  the digits as shown below with an additional column of sum of the digits.
