Lesson overview

Our client runs a nuclear power plant equipment supply warehouse. A cyber criminal (a disgruntled employee) has hacked the database on their last day and changed all of the products to cost £0.99. Our task is to delete the cyber criminal's accounts and fix the pricing!

  • First, we need search the database to find these unauthorised accounts

  • Once we have found the cyber criminals accounts, we need to run a command to delete them

  • After they've been deleted, we need to run a command to put the affected prices back to their original price, and save the company

  • Lastly, help keep the cyber criminals at bay by creating a stronger password for the company
