Few days ago i received an e-mail from a friend saying that he found a huge bug on Facebook. Actually this is a very big security threat if you are using too much private things on facebook. It is a problem affects to your photos and videos. Think about this before you upload images and videos to facebook. Because of this bug people can view and download videos and photos even after you deleted them from facebook.
Lets see how it work.
First select an image you want to delete. then open that image. it will be open in theater mode. Now copy image link address on address bar and paste it on notepad or any other place. it is the first link as shown in the image below. after that right click on the image and click on Copy image location. write down it as link number two. check this image to see how to check this bug on facebook.
Now delete the image and refresh page or go to the link number one again. you will see below error message.
That means that link not works anymore. now paste the link number two on address bar and press enter. see what happened? Your deleted photo still available on Facebook servers and if someone put the direct link on some where, they can see it even after you delete it. there are more ways to find those deleted photos without the direct link im not going to tell that in this page. anyway that is the problem facebook having and they are working on it.
This happens because facebook use a technology called Continent Distribution Network ( CDN ) that is a good thing facebook invented to secure our data as backups in few regional servers so we can access them very fast. But the problem is when we access photos and delete them on facebook it will only delete the file on the server that we used to load the image that time. Our images will remain in other servers. There are ways to get those deleted photos. so facebook staff now working on reducing that time they store deleted data on other servers. Hope they will fix it soon – Check Consumer Report Online.
