Leaking URLs to the Clown

The author shares a peculiar experience of leaking URLs while testing apps from the Mac app store. One of the unique URLs assigned to an app started receiving requests from a random "cloud" service without prior indication. Even after stopping the programs, the requests persist every three hours. The situation raises concerns about privacy as the app's web page implies offline access without internet connection, contradicting the continuous polling behavior. This unexpected data leakage highlights potential privacy risks for users accessing sensitive content through such apps.

So, if you were thinking about using that particular app to read some feed containing something relatively private, guess what, they're reading it too.

Which one? No names were named at any point in this post.

Everyone needs to accept the fact there's no such thing as a private URL. There are URLs that can be originally communicated to you privately—through a private channel, that is—but insisting on holding onto some (wrong) belief that we can or should be able to mint URLs that themselves possess some "private" quality goes against the fundamental design of the Web and what a URL even is.

(Yes, this does mean that every podcaster that implements subscriptions by giving one feed URL to free listeners and having listeners who pay for premium content use a different URL is fundamentally broken. Yes, this does mean that that big engineering organization that implemented file uploads and read/write access through slugs consisting of unguessable 128+ bit tokens is also wrong.)

Can’t tell if “clown” is an incredible typo in the submission or some comment on the owner of the offending platform, but either way I’m all about it

I made a bookmarklet that makes reading articles easier so that no browser extensions or reader apps need to access the data. Here is the link: https://news.ycombinator.com/item?id=40588645

I thought every feed reader did this. Well the ones with a server anyways.

Sorry, but I just don't see the "bad behavior" in polling a URL you purposefully requested it to retrieve.

URLs are not secrets. Don't treat them as such.

There is approximately zero point in calling out the bad behaviour of anonymous applications.
