The Economics of Cybercrime and Security: Checkpoint 1

Quick checkpoint - five questions on cyber threats, ransomware, black markets, underinvestment and the AIIMS attack.

Question 1 of 5 Why does the attacker-defender asymmetry favour attackers?

Attackers need one weakness; defenders must protect everything Attackers are always richer Defenders have no tools Laws protect attackers

This asymmetry makes defence costly.

Question 2 of 5 What is double extortion in ransomware?

Encrypting data and threatening to leak it Charging two victims Paying twice for insurance Two banks involved

Stolen data adds pressure to pay.

Question 3 of 5 What does crime-as-a-service mean?

Criminals specialise and sell tools and services to each other Police offering services A legal consulting firm Free software

Specialisation makes cybercrime efficient.

Question 4 of 5 Why do firms underinvest in security?

Externalities and information gaps Security is illegal Attacks never happen Security is free

Others bear part of breach costs.

Question 5 of 5 What happened at AIIMS Delhi in November 2022?

A ransomware attack shut down digital systems A new hospital opened Power was free A strike ended

Services ran manually for about two weeks.

We believe knowledge should be open to everyone, not limited by barriers.
