Unsolicited (CRYPTO) photos in my private photos on my iPhone.

I see encrypted photos on my phone that I didn't take. How does this happen??

Photos appear in the Photos app that were not taken by me or sent to me. These are crypto pricing photos, along with a few pictures of couples I don't know.

The same thing happened to me on November 17.

Since then I deleted the crypto junk photos, but they reappeared after 1 week.

I restricted access to the programs and deleted e.g. the Binance app.

The photos appeared again yesterday.

Now I disconnect the internet from my phone, do they still appear?

I read on a forum that this happened to someone else.

Does Apple already have a solution to this spam infection?
