RANSOMWARE ATTACK: A LESSON IN CYBERSECURITY Skills
Aarohi was working on her science project when she received an email that appeared to be from
her school. It read:
“Download the attached file for updated project guidelines.”

Without verifying the source, she downloaded the attached PDF. The moment she opened it, her
laptop screen froze, and a message appeared:
“Your files are locked. Pay `500,000 to unlock them.”
All her photos, notes, and school assignments were encrypted and inaccessible. Aarohi’s father
explained that this was a ransomware attack. The attacker had used the fake email and its
attachment to install malware that locked her files. In the end, Aarohi had to buy a new laptop. She
lost all her data and had to begin her project again.
Based on the above case, answer the following questions:
1. What made Aarohi believe the email was from her school?

2. What type of cyber threat attacked her device?
