The situation

A polished onboarding message asks for a password export to unlock a premium keyboard. This fictional security exercise asks you to check the request and challenge 8-BIT's unsafe proposal. Lydia explains the correction in the same scene.

What you'll learn

  • Recognising phishing; multi-factor auth; keeping software updated.
  • Backups and recovering a deleted file; data classification.
  • Challenging a confident but unsafe AI suggestion with evidence.
  • Following an authorised simulated incident response: contain, remove persistence, recover and complete the report; initial alerting happens at the start.
