Before she even understood the situation, it escalated further. A deepfake video profile of Ishita appeared
online—her face on another body, paired with a fake AI-generated voice. A classmate, Karan, spread
rumours based on the deepfake, claiming Ishita was secretly ill and hiding things from the school.
Ishita was devastated. Her digital identity had been stolen, manipulated, and misused.
Both cyber incidents collided on the same day. The school’s cyber team noticed:

Mass ransomware alerts IoT device failures
Students receiving scam messages Fake videos circulating

Massive login attempts from unknown locations

Teachers informed the Cyber Cell. Officers arrived and traced:

The portal breach to Dev’s phishing email
The spyware and deepfake creation to Ishita’s AI app

The IoT takeover to weak device passwords
The spread of rumours to student misuse

Dev and Ishita were not criminals—but their careless actions had caused a chain reaction affecting the
