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.
Data 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.
