The “Hack” that lets stalkers view your private instagram content and solution

A few months ago I saw a news report that you could share private instagram pictures/videos/stories easily by extracting the url from the html code. This made it possible for people that did not follow your private account to view your content. I am going to test if Instagram has fixed this “feature” or if they left it in their backlog. If the latter, I will be stating how they could easily resolve this issue. 

“The hack works even when images and videos in a private Instagram story, which are meant to last for only 24 hours, expire or are deleted. Linking URLs to content from stories seems to be valid for a couple days; links to photos on the feed remain live for potentially even longer. The same is true for stories that have purportedly expired.”

Hacking Begins

This is my private instagram account: https://www.instagram.com/jaype_rt/

And here is a link I was able to extract for the source code on instagram: https://instagram.fzty2-1.fna.fbcdn.net/v/t50.2886-16/69234542_2489955347929391_8639978899384758635_n.mp4?_nc_ht=instagram.fzty2-1.fna.fbcdn.net&_nc_cat=111&_nc_ohc=uetTBTW9COwAX-i31_l&oe=5E35AAA7&oh=50279a03b50b5dcdf367304b98c985a1 

So as we have just discovered, instagram is being lazy.

Solution

This solution requires AWS. Instagram is owned by Facebook and they have their own server infrastructure. However, I can’t imagine they don’t have the ability to implement this feature if necessary.

AWS provides a service called “Signed URLs” 

A signed URL includes additional information, for example, an expiration date and time, that gives you more control over access to your content. Signed URLs also have the ability to give a particular link certain access rights. For example, it could require the user to login in order to view the content in the link. Or it could also require the link be be accessed from a specific webpage/app. So instagram could make it possible for the content to only be viewable if requested from within their own domains.

Introduce Yourself (Example Post)

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

  • Because it gives new readers context. What are you about? Why should they read your blog?
  • Because it will help you focus you own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

  • Why are you blogging publicly, rather than keeping a personal journal?
  • What topics do you think you’ll write about?
  • Who would you love to connect with via your blog?
  • If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
