I get a pop-up window asking "Do you want to download "occ" in my Safari browser

For me, the "download occ" message started AFTER the update to iOS 18 on a 13 Pro. Never saw it before and I read the news across multiple sites daily on iPhone. I make it a habit not to click on anything but the articles.

The only change before and after was the update. Would be nice if the IT folks could track this down to its source.

I have added my experience here on this thread confirming the unexpected page.

Have also submitted it to Apple Feedback.

I selected the IPad Safari link

Earlier I posted a comment that said Apple should test their software more thoroughly before rolling it out. When I said that, I did not consider the possibility that the prompt to download OCC is caused by a web component on the backend web server, rather than on the iOS device. So I’d like to apologize for that comment. It’s very possible software running on the web server that is common to news websites, is actually causing the problem on iOS devices running safari. Sorry Apple. But I still would like to know the root cause.

Thank you for your post! While we don't have to believe that Apple is perfect and never makes mistakes, we also don't need to blame Apple for everything that we encounter using our devices. I do believe Apple can mitigate this popup with a point update to the OS even if it is caused by a third party service, but that will take time as they first need to determine what caused it and then need to test the update before releasing it to make sure the fix does not break something else. It is also possible that a third party ad service will identify the problem themselves and quietly fix it without any comment. Time will tell and hopefully we will see an explanation, otherwise it just leads to speculation that serves no purpose.

Well, I thought installing Adguard solved it for me. But, it’s back this morning, and this message showed up when I logged into my bank account:

Do you want to download “_codexch”?

I X’d it out, but I assume Apple is unable to help at all.

Check with your bank, as _codexch can be part of single sign-on processing.

Seems likes it happens with the first few links at the top of the search, not always, but always annoying. It happens with Reddit links, news, and just random stuff. It even happens if you click a link from images, I did that, got the pop up, closed it, and clicked a diff area and it actually loaded correctly, so it’s like something is in front of the place you’re clicking, i dont know, or, it one certain areas for some reason.

I also hit download one time by mistake lol, it saved to my files but it was nothing, I just deleted it.

I started getting it last night, I was looking at news. Now it’s nearly constant. iPhone XS Max running 16.1.2, so this isn’t related to phone updates.

It seems like this is appearing through banner ads on news websites? Potentially a bug or security issue with the provider of those banners

Cleared website data, restarted. Came up on local news site as a test.

Get it in chrome and safari after updating to 17.7 on both iPhone 12 Pro Max and iPad Pro 3rd gen

I’ve been seeing this as well, I don’t think it’s an apple issue, except for not block a non click download initialization. It seems to be tracking with ad changes

Ditto. Just started happening. I’ve done a full shutdown restart of the phone (twice now) When it popped up again on a different site, I looked into it and the only returns I see are from others asking in Apple support about it. iOS 18 on iPhone 15 pro max.

I’m chatting with an apple support person now as this was freaking me out. It seems as if it’s connected to news type sites. The support person is looking into but they have nothing on record as of yet. I’ll circle back if I’m given any useful info.

I actually just created this account sicne I went on a search of Google and landed on your question. Will be interesting to hear what others report back about what Apple says.

ps- I’m on a 13 PM running iOS 15.0.2

The occ download message has been popping up for about a month. Ive ignored it the whole time. I got re-interested in it when I had message to download sys the other day.

It tends to pop up in “news” sites. I think it’s linked to one or more advertisements.

Just happened to me as well. I was on DeadlineHollywood.com and it popped up. I x’d out of it, but I hate when prompts like that pop up because it usually means the bug is already on your phone. Do we know this is for sure related to the updated iOS, which I downloaded 3 days ago.
