There’s no doubt that data breaches are a primary concern for people on the technological side of any modern business.

However, it’s increasingly the case that C-suite executives are catching wind of the potential business ramifications that these breaches can trigger.

In 2013, for example, the hacking of Yahoo not only compromised three billion email accounts – it also nearly jeopardized Verizon’s bid to acquire the company for $4.8 billion. At the end of the day, experts say that the breach knocked $350 million off of the sale price of Yahoo.

Counting Down the Breaches

Today’s infographic comes to us from Hosting Tribunal, and it highlights the biggest data breaches over the last 15 years.

The 15 Biggest Data Breaches in the Last 15 Years

Did you know that a whopping 14,717,618,286 records have been stolen since 2013?

It’s part of a much larger problem, and some experts anticipate that by 2021 the cost of cybercrime to the global economy will eclipse $6 trillion – a potential impact that would even supersede the size of the current Japanese economy ($4.9 trillion).
