Cryptography Homework: Ransomware Riddles

Background

In this homework assignment, you will play the role of a cybersecurity analyst at Nakatomi Hospital.

• Unfortunately, one of the hospital’s doctors opened up an email containing ransomware.
• This ransomware spread throughout the hospital and encrypted all of the Patient Records.
• The ransomware has given you two options to decrypt and retrieve the patient records: Either pay 100 bitcoins or solve six riddles.
• Since you refuse to pay off any ransom, you’ll have to solve six cryptographic riddles. Act fast: the doctors need to access the patient records as lives are at stake!

Additionally, a Career Service Milestone is located at the end of this file. Complete it to learn how to become more Employer Ready.
