The 15 Biggest Data Breaches in the Last 15 Years

Published

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).

The 15 Biggest Data Breaches

Here are the most notable breaches that have occurred over the last 15 years, in ascending chronological order:

YearCompanyImpact
2004AOL92 million screen names and email addresses stolen
2013YahooAll 3 billion accounts compromised
2013Target110 million compromised accounts, incl. 40 million payment credentials
2014eBay145 million compromised accounts
2015Anthem Inc80 million company records were hacked, including Social Security numbers
2016LinkedIn117 million emails and passwords leaked
2016MySpace360 million compromised accounts
2016Three133,827 compromised accounts, including payment methods
2017Equifax143 million accounts exposed, including 209k credit card numbers
2016Uber57 million compromised accounts
2018Marriott500 million compromised accounts
2018Cathay Pacific9.4 million compromised accounts, including 860k passport numbers
2018Facebook50 million compromised accounts
2018Quora100 million compromised accounts
2018Blank Media7.6 million compromised accounts

Most of these breaches led to millions, or even billions, of records being compromised.

And while the motives behind cyberattacks can vary from case to case, the business impact of hacks at this scale should make any executive tremble.

Charted: The Jobs Most Impacted by AI

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Large language models (LLMs) and other generative AI tools haven’t been around for very long, but they’re expected to have far-reaching impacts on the way people do their jobs. With this in mind, researchers have already begun studying the potential impacts of this transformative technology.

In this graphic, we’ve visualized the results of a World Economic Forum report, which estimated how different job departments will be exposed to AI disruption.

Data and Methodology

To identify the job departments most impacted by AI, researchers assessed over 19,000 occupational tasks (e.g. reading documents) to determine if they relied on language. If a task was deemed language-based, it was then determined how much human involvement was needed to complete that task.

With this analysis, researchers were then able to estimate how AI would impact different occupational groups.

DepartmentLarge impact (%)Small impact (%)No impact (%)
IT73261
Finance70219
Customer Sales671617
Operations651817
HR57412
Marketing56413
Legal46504
Supply Chain431839

In our graphic, large impact refers to tasks that will be fully automated or significantly altered by AI technologies. Small impact refers to tasks that have a lesser potential for disruption.

Where AI will make the biggest impact

Jobs in information technology (IT) and finance have the highest share of tasks expected to be largely impacted by AI.

Within IT, tasks that are expected to be automated include software quality assurance and customer support. On the finance side, researchers believe that AI could be significantly useful for bookkeeping, accounting, and auditing.
