Person's hand with credit card: The Latest Data Breach News

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.

Since 2013, we’ve monitored security breach breaking news and tracked those having the biggest impact on Americans. Remember the big Target breach? 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.

How To Protect Yourself From Data Breaches

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.

Be proactive by signing up for Identity Theft Protection and reading our Basic Cyber Security Tips to stay ahead of the game. For a minimal monthly payment, you’ll rest assured knowing that someone is keeping a close eye on your credit.

Visual History Of Data Breaches Since 2012

To see how the various breaches compare, we complied a graphic showing the breadth and depth of each major compromise including a timeline of when each event happened, was announced to the public, who it impacted and the resolution (if any). The results showcase the full scope of this massive concern plaguing society today.

Where is it happening most? 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

I heard this week that Uber compromised user data…and knew about it for a year!
Denise W
Thanks for keeping these data breaches covered, very helpful! It’s nice to have a source that only covers the major stuff, not all the breaches, which can get overwhelming! You say that I’m able to check the Equifax site you link to to find out if my data has been exposed, but once I get to the site I can’t find where to get that information?
Alex Schenker (Admin)
Hi Denise, if you use the link we provide above (here it is again) vs. going to the homepage of the Equifax site, you’ll be taken straight to a page that gives you instructions on checking the potential impact on your data (you’ll be asked for your last name and the last 6 digits of your SSN). We recommend you sign up for an identity theft monitoring service (we review the top ID theft protection services here) to help monitor and protect against future breaches.
This is useful, will bookmark it and reference often, hopefully there won’t be too many more updates to this though!
