Visualizing The 50 Biggest Data Breaches From 2004–2021
As our world has become increasingly reliant on technology and data stored online, data breaches have become an omnipresent threat to users, businesses, and government agencies. In 2021, a new record was set with more than 5.9 billion user records stolen.
This graphic by Chimdi Nwosu visualizes the 50 largest data breaches since 2004, along with the sectors most impacted. Data was aggregated from company statements and news reports.
Understanding the Basics of Data Breaches
A data breach is an incident in which sensitive or confidential information is copied, transmitted or stolen by an unauthorized entity. This can occur as a result of malware attacks, payment card fraud, insider leaks, or unintended disclosure.
The targeted data is often customer PII (personally identifiable information), employee PII, intellectual property, corporate data or government agency data.
Date breaches can be perpetrated by lone hackers, organized cybercrime groups, or even national governments. Stolen information can then be used in other criminal enterprises such as identity theft, credit card fraud, or held for ransom payment.
Notable Data Breaches Since 2004
The largest data breach recorded occurred in 2013 when all three billion Yahoo accounts had their information compromised. In that cyberattack, the hackers were able to gather the personal information and passwords of users. While the full extent of the Yahoo data breach is still not fully realized, subsequent cybercrimes across the globe have been linked to the stolen information.
Here are the 50 largest data breaches by amount of user records stolen from 2004–2021.
|2||River City Media||Web||1.4B||2017|
|4||First American Corporation||Finance||885M||2019|
|12||Friend Finder Network||Web||412M||2016|
|22||Chinese resume leak||Web||202M||2019|
|25||Deep Root Analytics||Web||198M||2015|
|30||Massive American business hack||Finance||160M||2013|
|38||Pakistani mobile operators||Telecoms||115M||2020|
|45||TK / TJ Maxx||Retail||94M||2007|
|50||Sony Playstation Network||Gaming||77M||2011|
The massive Yahoo hack accounted for roughly 30% of the 9.9 billion user records stolen from the Web sector—by far the most impacted sector. The next most-impacted sectors were Tech and Finance, with 2 billion and 1.6 billion records stolen, respectively.
Although these three sectors had the highest totals of user data lost, that doesn’t necessarily imply they have weaker security measures. Instead, it can probably be attributed to the sheer number of user records they compile.
Not all infamous data breaches are of a large scale. A smaller data breach in 2014 made headlines when Apple’s iCloud was hacked and the personal pictures of roughly 200 celebrities were disseminated across the internet. Although this highly targeted hack only affected a few hundred people, it highlighted how invasive and damaging data breaches can be to users.
The Cost of Data Breaches to Businesses
Every year data breaches cost businesses billions of dollars to prevent and contain, while also eroding consumer trust and potentially having an adverse effect on customer retention.
A 2021 IBM security report estimated that the average cost per data breach for companies in 2020 was $4.2 million, which represents a 10% increase from 2019. That increase is mainly attributed to the added security risk associated with having more people working remotely due to the COVID-19 pandemic.
Measures to Improve Data Security
Completely preventing data breaches is essentially impossible, as cybercrime enterprises are often persistent, dynamic, and sophisticated. Nevertheless, businesses can seek out innovative methods to prevent exposure of data and mitigate potential damages.
For example, after the iCloud attack in 2014, Apple began avidly encouraging users to adopt two-factor authentication in an effort to strengthen data security.
Regardless of the measures businesses take, the unfortunate reality is that data breaches are a cost of doing business in the modern world and will continue to be a concern to both companies and users.

Charted: What are Retail Investors Interested in Buying in 2023?
What key themes and strategies are retail investors looking at for the rest of 2023? Preview: AI is a popular choice.
Charted: Retail Investors’ Top Picks for 2023
U.S. retail investors, enticed by a brief pause in the interest rate cycle, came roaring back in the early summer. But what are their investment priorities for the second half of 2023?
We visualized the data from Public’s 2023 Retail Investor Report, which surveyed 1,005 retail investors on their platform, asking “which investment strategy or themes are you interested in as part of your overall investment strategy?”
Survey respondents ticked all the options that applied to them, thus their response percentages do not sum to 100%.
Where Are Retail Investors Putting Their Money?
By far the most popular strategy for retail investors is dividend investing with 50% of the respondents selecting it as something they’re interested in.
Dividends can help supplement incomes and come with tax benefits (especially for lower income investors or if the dividend is paid out into a tax-deferred account), and can be a popular choice during more inflationary times.
|Investment Strategy||Percent of Respondents|
|Total Stock Market Index||36%|
|Gold & Precious Metals||23%|
Meanwhile, the hype around AI hasn’t faded, with 36% of the respondents saying they’d be interested in investing in the theme—including juggernaut chipmaker Nvidia. This is tied for second place with Total Stock Market Index investing.
Treasury Bills (30%) represent the safety anchoring of the portfolio but the ongoing climate crisis is also on investors’ minds with Renewable Energy (33%) and EVs (27%) scoring fairly high on the interest list.
Commodities and Inflation-Protection stocks on the other hand have fallen out of favor.
Come on Barbie, Let’s Go Party…
Another interesting takeaway pulled from the survey is how conversations about prevailing companies—or the buzz around them—are influencing trades. The platform found that public investors in Mattel increased 6.6 times after the success of the ‘Barbie’ movie.
Bud Light also saw a 1.5x increase in retail investors, despite receiving negative attention from their fans after the company did a beer promotion campaign with trans influencer Dylan Mulvaney.
Given the origin story of a large chunk of American retail investors revolves around GameStop and AMC, these insights aren’t new, but they do reveal a persisting trend.
