Why Cyber Attacks Keep Growing

Why cybercrime has become a huge global business, what it costs economies, and why digitisation creates new targets.

As more of life moves online, cybercrime has grown into a vast illegal industry.

The cost

Estimates of global cybercrime costs run into trillions of dollars a year, including stolen money, ransom payments, downtime, recovery and lost trust. Exact figures are uncertain, but the trend is clearly upward.

Why attacks grow

More targets: digital payments, cloud services, connected devices.
Low cost for attackers: tools can be bought cheaply online.
Low risk: attackers often operate from countries where they’re unlikely to be caught.
High rewards: ransoms and stolen data are valuable.

India’s exposure

India’s rapid digitisation, from UPI to Aadhaar-linked services, creates many targets.
CERT-In, India’s cyber agency, handles lakhs of reported incidents a year.

Economics of attack vs defence

Attackers need to find one weakness; defenders must protect everything. This asymmetry favours attackers.

Who pays

Businesses: lost revenue and recovery costs.
Consumers: stolen money and data.
Governments: disrupted services.

The cheap attack

An attacker rents ready-made hacking tools online for a small fee, launches attacks on hundreds of small firms and needs just one to pay a ransom to profit.

Thinking cybercrime is just lone hackers

It's an organised industry with tools, markets and business models.

Key takeaways

Cybercrime costs are estimated in trillions of dollars a year.
Digitisation creates more targets.
Low cost and low risk attract attackers.
Defenders must protect everything; attackers need one gap.
