The 15 Biggest Data Breaches in the Last 15 Years

Published

on

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

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.

Ranked: The Top 50 Most Visited Websites in the World

Estimates vary, but there are upwards of two billion websites in existence in 2023.

If we were to rank all of these websites according to their traffic numbers, we would see a classic power law distribution. At the low end, the vast majority of these websites would be inactive, receiving little to no traffic. On the upper end of the ranking though, a handful of websites receive the lion’s share of internet traffic.

This visualization, using data from SimilarWeb, takes a look at the 50 websites that currently sit at the top of the ranking.

Which Websites Get the Most Traffic?

Topping the list of most-visited websites in the world is, of course, Google. With over 3.5 billion searches per day, Google has cemented its position as the go-to source for information on the internet. But Google’s dominance doesn’t stop there. The company also owns YouTube, the second-most popular website in the world. Together, Google and YouTube have more traffic than the next 48 websites combined.

The power of YouTube, in particular, is sometimes not fully understood. The video platform is the second largest search engine in the world after Google. As well, YouTube has the second highest duration-of-visit numbers in this top 50 ranking. (First place goes to the Chinese video sharing website, Bilibili.)

But Google and YouTube aren’t the only big players on the internet. Other websites in the top 50 ranking include social media giants Facebook, Instagram, and TikTok. In particular, TikTok has seen a surge in popularity in recent years and is now one of the most popular social media platforms in the world.

The Geography of the 50 Most-Visited Websites

The United States is still home base for many of the world’s biggest websites, taking up 30 spots on this ranking. Of these 30 websites, half are operated by Big Tech companies such as Microsoft, Amazon, Alphabet, Meta, and Netflix.

Russia, China, Japan, and South Korea round out the top five.

Things get interesting in the “other” category, which includes six websites. Two spots are taken up by Aaj Tak and Globo, which are large media publications in India and Brazil, respectively.

The remaining four websites—XVideos, PornHub, XHamster, and XNXX—specialize in adult content, and are located in a variety of countries. These are often referred to as “tube sites” since they are built on the YouTube model.

Realsrv, the only adult-oriented site in the top 50 located in the U.S., is interesting to delve into as well, since it’s far from a household name. The website essentially supports advertising efforts by redirecting users away from the content they were viewing over to another page (generally premium adult content). This is one of the key ways that adult websites earn revenue.

Where does this data come from?

Source: SimilarWeb

Notes: Websites listed include “all meaningful subdomains”, and categories in the graphic follow SimilarWeb’s categorization system. This is the third version of this graphic. As with previous versions, we aim to use data from November for the sake of consistency and to avoid seasonal fluctuations in traffic. One important detail to point out is that website traffic does not include app traffic, which is why popular platforms like WeChat don’t appear in this ranking.
