Scope of Impact
Billions of accounts: Facebook has ~3 billion users; Gmail serves over 1.8 billion. A combined breach could expose more than half of the global online population.
Personal data: Private messages, photos, videos, location data, emails, passwords, and even deleted content could be compromised.
Institutional risks: Government agencies, corporations, journalists, and activists using these platforms could be vulnerable to espionage, blackmail, or manipulation.
