8 Worst Security Breaches: Is Your Data Safe?
The information age is made possible by the lightening-fast exchange of data, making that data today’s all-important currency. As precious as our personal and private data is today, it must be kept safe.
How Safe Is Your Data?
Individuals can take action to safeguard our usernames, passwords, and personal information. But when every precaution is taken, is your information guaranteed to be kept out of the wrong hands?
Who gets access to the data on your credit card’s magnetic strip when it’s swiped through that card reader? Who’s able to see the username and password you use on your favorite shopping sites?
Ever since sensitive personal information has been stored on computers, there have been hackers who have done their best to break into these systems and access that information to sell it to the highest bidder.
How Cyber-Thieves Steal Information
By hacking into computer systems and wireless networks, computer-savvy thieves can install malware to capture information like credit card numbers, usernames, and passwords at the press of a button. In some of the top security breaches in history, millions of credit card numbers have been captured by a single hacker. In 2012 alone, according to a study by McAfee, more than 25% of Americans were victims of a data security breach.
In the case of some government security breaches, the person who leaked the data didn’t have to hack into a single computer, but was handed those secrets in the course of their jobs, only to turn it over to the public, sometimes putting lives at risk.
What’s worse, some of these hacked organizations delayed informing their customers, instead choosing to place priority on preserving their own reputation. Those delays put their customers at even more risk, leaving them unable to take measures to protect their information and recover their privacy.
You Can Keep Yourself Safe
There are precautions you can take to keep your sensitive data safe, like creating strong passwords and choosing carefully who you give your information to. But once your data’s out in the cloud, there are no guarantees. The eight worst security breaches below show that no system is 100% safe.

The biggest challenge to data security is not external, but the enemy within. While most are criminal, the most sensitive data breaches were perpetrated by Snowden and Manning – acting in accordance with their conscience and, so they hoped, in the public interest.
Whatever your stance on their actions, one thing remains clear – NO system is impregnable.
