# OptimiseMe $ ./xvm optimiseme.xvm flag : zh3^C $ # :) ### Author: X3eRo0 ## Soln [xvm source code](https://github.com/x3ero0/xvm) Dissassemble the .text section of optimiseme.xvm and you will find that the binary is using fibonacci sequence with recursive approach to slow down the calculation. optimise the algorithm to get the flag or just decrypt the flag manually. ## Flag zh3r0{967a23927d374a7e58e7a12ef62f5}
