A hacker group has shared 13,000 passwords of sites like Amazon, Walmart

Hacker group Anonymous has released a file containing about 13,000 'passwords'. The stolen account information has been posted to internet file sharing site Ghostbin.

That's not the biggest password hack we've ever seen. With millions of passwords in use for sites around the internet, chances are, yours is not among these 13,000.

But these accounts come from a variety of online sources, the Anonymous claims, some of them really popular.

DailyDot's Aaron Sankin sifted through the file and discovered the leaks came from the following sites:

* Amazon

* Walmart
* PlayStation Network
* Xbox Live
* Twitch.tv
* Origin.com
* Hulu Plus
* Dell
* Shutterstock

The file also included the accounts of a number of dating and porn sites, and it appears to have some passwords for a popular security programme known as CyberGhost, which protects you from a hacker snooping on you when you use public Wi-Fi hotspots.

Just to top it off, Anonymous also posted a copy of the movie "The Interview" making it available for pirated downloads, it said. In an earlier tweet, the group boasted, "When you're a pirate, everything is free."

There are two take-aways from this: 

1) If you use any of the above online businesses, watch for unusual activity. You can also just change your password now.

2) This is another warning that the bad guys are plentiful in cyberspace. So change passwords frequently. Don't use the same ones over and over and if you bank or shop online, always keep an eye out for weird things or unauthorized purchases with your accounts.
