From government organizations to major retailers, headlines about data breaches seem to be the new norm. Hackers continue to put millions of consumers at risk. If you’re reading this, you’ve most likely experienced an attack at some point.
Important Update For COVID-19
In April 2020, the Treasury Department announced automatic economic payments to taxpayers as part of the stimulus bill for Coronavirus (COVID-19) relief. The Internal Revenue System (IRS) is urging Americans to stay on the lookout for phishing scams related to these distributions.
Phrases like “stimulus check” or “stimulus payment” are warning flags (the correct phrase is “economic impact payment”). Also, the IRS will not be calling to verify financial information. Visit the official website to find out if you are eligible and how your funds will be sent to you (via direct deposit or check). And if you suspect potential fraud, report it to the Federal Trade Commission (FTC).

Since 2012, we’ve monitored security breach breaking news and tracked those having the biggest impact on Americans. Remember the big Target breach from 2013? That seems like ages ago with 10,000+ violations in the U.S. since January 2018 alone, resulting in 10.7 billion exposed records1. That makes Target’s 40-70 million affected customers seem like peanuts in comparison.
Where Are Most Data Breaches Happening In The U.S.?
Ironically, California, home to Silicon Valley, suffers the worst magnitude and frequency of breaches (double the next hardest-hit states: New York, Texas and Florida). On the flip side, the Dakotas, Wyoming and West Virginia remain relatively in the clear with the fewest breaches (under 30 total).1
Identity theft can happen even to the most cautious of us. As you can see from the list of security breaches below, millions of people have had their personal information stolen. And in most security breaches, the hacked company offered affected customers an identity theft protection service. But that’s not as helpful when your information was already compromised.
We also recommend Dashlane to generate extra difficult to guess passwords. Dashlane also safely stores passwords, credit card info and other sensitive data. Read our Best Password Managers article to learn more.
Trying to keep up with all the latest security breach news and which companies have been affected can be overwhelming. We’ve put together this comprehensive guide to help you stay on top of what’s happening with the latest security breaches.
