It hasn't been a good year for company security. I've told you about the major data breaches at Target, Yahoo!, Adobe, Michael's, Neiman Marcus, eBay, Goodwill and plenty of others. That's just the tip of the iceberg.
If you add in smaller data breaches, there were more than 2,000 breaches in the last year, and hackers got their hands on more than 800 million user records! Hackers released a lot of this information online, just for fun.
Fortunately, some helpful programmers put together ways to see if hackers have released your information.
The story isn't as one-sided as it might seem, though, because it isn't just legitimate retailers and online sites that get hacked. Hackers can use bad passwords and have poor security, too.
Plenty of hackers attack other hacker sites, steal information and then release it online.
