Top 10 Data Breaches of the Decade

Reflecting on the last decade, we can learn a lot, especially regarding how the importance of cyber security is always increasing. We have seen trends in cybercrime continue to rise, and cyber criminals rely on a variety of tactics.

Looking back at the top 10 breaches of the last decade can help us prepare for a more cyber secure future.


Education Credit Management Company

  • In March of 2010 a “portable media device” was stolen that contained the names, addresses, dates of birth, and social security numbers of 3.3 million students who have student loans in the US.
  • 3.3 million students affected make up 5% of all students who have loans in the US.
  • “Simple, old-fashioned theft,” said EMCC spokesperson.


Sony PlayStation Network

  • 77 million people’s names, addresses, emails, birthdates, usernames, passwords, security questions and more were involved in the breach.
  • The breach caused PlayStation Network to be inaccessible to users for a period of time
  • A senior technology consultant from SOPHOS security firm said the breach was a “Public relations disaster.”



  • 117 million users were affected by the breach
  • 167 million accounts and 117 breached passwords after LinkedIn originally reported only 6.5 million users affected.
  • “We take the safety and security of our members’ accounts seriously. For several years we’ve offered protection tools such as dual factor authentication,” stated Cory Scott, LinkedIn’s Chief Information Security Officer.





  • 145 million users were affected.
  • The breach originated from a much smaller breach in which a number of employees login credentials were stolen.
  • “We want to make sure it doesn’t happen again, so we’re going to continue to look at our procedures, harden our operational environment and add levels of security where it’s appropriate,” said an eBay spokesperson.


US Voter Information

  • 191 million voters had details of their registration exposed. The data included names, addresses, birthdates, party affiliations, phone numbers, and emails.
  • The breach was caused by an incorrectly configured database, which allowed voter’s data to be sitting on the internet exposed.







  • 50 million users were affected. The breach included user’s sensitive information, including locations, contact details, relationship status, recent searches, devices used to log in, and more.
  • Accounts that were affected and were used to log into other apps with Facebook were compromised as well.
  • “It definitely is an issue that this happened in the first place. I think this underscores the attacks that our community and our services face,” stated CEO Mark Zuckerberg.



  • 500,000 passwords of Zoom accounts were the result of the breach.
  • The breach was facilitated by criminal’s accessing passwords and usernames that had been involved in previous data breaches.
  • “Unfortunately, people tend to reuse passwords…this is why the price is so low per credential sold (on the dark web), sometimes even given away for free,” stated a spokesperson for Zoom.

Have You Been A Victim of a Data Breach?

If you’ve been involved in a data breach the best thing you can do for the safety of the rest of your accounts and your business is to change compromised passwords immediately and cease using the compromised passwords for other accounts. You can easily enable multi-factor authentication to protect your accounts too.

Without the right protection, you’re putting yourself and your company at risk. Studies have shown that almost 80% of data breaches could have been stopped if multi-factor authentication was enabled.

If you’re not sure if you’ve been involved in a data breach or not, you should check. A tool called Have I Been Pwned was developed by some of the good guys to help users identify if they’ve been a victim of a data breach. All you need to do is enter your email into the search bar, and within seconds you’ll be able to see if you’re email address has been involved in a data breach, and even which ones.

You can also test your passwords the same way to make sure you’re not using compromised ones.
