All Your Bitcoin Are Belong To Us

   If you're old enough... and geeky enough, you may remember this:


   All Your Base Are Belong To Us was one of the famous early internet memes.  You can take a break and read more about it here and here.

   Memes are fun!  But ransomware isn't.  We've talked about ransomware many times in the past.  It's a kind of virus or malware (malicious software).  It's been in the news quite a bit and the healthcare industry has had particular ransomware problems.  And the news will continue after May's "WannaCry" and June's Petya/GoldenEye global attacks.

   Basically, in a ransomware attack, infected computers cause data to be encrypted.  Normally encryption is a good thing, but only when you can also decrypt your data.  In this attack, only the attacker can restore your access to the information, and will do so for a "small consulting fee".

   Payment is typically made using Bitcoin.  Bitcoin has also been in the news.  It is what is called a "crypto-currency".  It's basically an online way to pay for things, kind of like an online debit card where you already have the funds in your account.  The main reason Bitcoin is used for ransomware is that it is fairly anonymous, particularly when compared with traditional credit cards or banking.  It's not completely anonymous - it does protect identity during transactions, but eventually someone may have to turn that bitcoin into other traditional currency.

   With all the ransomware attacks, some organizations are getting bitcoins so that they are ready in case they need to pay ransom!

I Know Where Your Cat Lives!

   Today's post brings together two of the most important, popular and topics online - security and privacy of your information on the Internet and... Cats!

   We know why the first topic is important.  I've written plenty about data breaches, keeping yourself safe online and how to decrease your exposure to identity fraud.  But cats?  Interestingly, the Internet has had a long fascination with cats.  And memes are everywhere starting with the early days of Lolcats and Keyboard Cat.  Disclaimer - I am not a cat person... I don't own any and am not a fan.  But I do like a good meme!

  Regardless of your pet of choice, we do care about our pets and they are often treated like members of the families.  And that includes... pictures.  If you do a search on cat pictures or pet pictures, you'll see plenty.  If you look on people's social network profiles, Facebook, Instagram, Pinterest, etc., there will be pet pictures all over the place.  You can even find them on "professional" sites like LinkedIn.

   Looping back to security and privacy... it's hard enough to keep your data safe when you're deciding what to share.  Many sites deal with the normal stuff - name, A/S/L, credit card numbers, and more.  You can enter this info to a site, or not.  But it's much harder when you don't realize that you are sharing data.  Or, put another way, how do you know when you're sharing more than you think you are.  There is hidden data and data sharing happening on the net everywhere.  For example, when you connect to a website, that connection creates a log that includes things like: your IP address, your browser type, your computer/phone/tablet operating system and other info.  The site may put a "tracking cookie" on your machine to help customize your experience while gathering more data.

   Then there's metadata.  This is data about data.  For example, when you take a picture with a digital camera or your phone, there is all kinds of additional data "attached" to that photo including: location, IP address, and timestamp.  There is also a great deal of extra visual information, other than the core subject in the photo including: views of your house, entrances, other people and surroundings.

   There is a fun and interesting website called "I Know Where Your Cat Lives".  They simply connect to photo sharing and social sites, grab cat photos, mine the metadata, connect the photo to a map, and create stats and charts.  Oh yes, and display cat photos!

   The lesson here is to pay attention to your digital surrounding.  When you take a picture, know what else is in that picture.  When upload a picture to a site, think about what data is going with that picture.  Most photo software gives you the ability to edit and alter most of the metadata.  Are you automatically uploading photos?
