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

I recently updated to iOS 18.0 a couple days ago. In my Safari web browser i get a pop-up window asking me if I want to download occ. I had this occur several times on different sites. I “x” the window closed. I have no idea what ‘occ’ is and as a precaution will not download anything that I have no clue about. see attached screen shots below.

Thanks

Try loading an ad blocker, and adjust its settings to both allow you into the intended website, and to block this occ download request.


Looking into this occ topic again, a newspaper website had a discussion (with no more details than anybody else has about this), and that webpage itself amusingly served up the occ download.


I’d expect this is some rubbish being served from an ad network somewhere.


Ad networks are too often flaming security trash-fires, unfortunately.


Try an ad blocker.

I have been getting it for the past week. Yesterday I got the message when I was in my local TV channel page. It MAY have started when I updated to 17.6.1 last weekend.


I’ve not gone to 18 yet as I read some horror stories and will wait until they sort those out b4 going to 18.0.


in all the years I’ve been on Apple (iPhone3) I’ve never seen anything like this “occ”. Apple’s strength has been keeping those out. I still can’t see where to report it and that’s probably why many, many others have not as well.

Hey! I totally understand your concern about that pop-up. It can be really frustrating when unexpected messages show up, especially after an update. If you're curious about what "occ" is and how to handle that pop-up in Safari, I came across a helpful article that explains it. You might find it useful: Hope it helps!

Mac Jim ID - Thanks so much for the information.


It makes iOS sound invulnerable, but I note in a different article that "Apple's long-awaited iOS 18 refresh landed Monday with fixes for at least 33 security vulnerabilities that expose iPhones and iPads to an assortment of malicious hacker attacks." () so is it possible that anyone encountering this issue before updating to iOS 18 could be in danger?

Every update contains security improvements as that is what makes iOS the most secure platform in the world. The part in your article that you failed to mention was: "The company did not mark any of the iOS 18 vulnerabilities in the already-exploited category." None of which is related to the topic on hand where an executable downloaded from the internet can be launched. Try it for yourself by downloading a .exe or .app file and try and run it. You will see that it is not possible.


Your rhetoric is more in line with posts from security bloggers who get their money/clicks the same way you see AntiVirus software attempting to scare users into believing they need their product to keep their devices safe. Fyi, those ads are scams.

I'm using an older iPhone (SE, but the second version) and iOS 17.4.1. I tend to keep things as they are - minimum upgrades - until I have to make a change. Most recent update to 17.4.1 was probably a few weeks ago (required by my bank's mobile app).

The "download occ" popup started for me on Sept 19, 2014 (two days ago), using Safari. I didn't X anything, just backed out of that page. It reoccurred multiple times: nerves and stress. I re-booted my router and phone, went to MSNBC, clicked on one headline, started to read a little bit, and got the prompt again.

I'm generally extremely careful about my clicking; if I get somewhere I shouldn't be, it's usually a finger-touch error. Mostly use my phone browser for news, word games, plant id and research. I'm reluctant to download or install anything - including ad blockers. Not sure why, but no prompts since late last night, knock on wood! Just adding my specs for stats even though I don't think they reflect anything new.

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.

Yahoo screwed up somewhere within their data collection / tracking / analytics implementation, as a guess.


I’d doubt we’ll ever see an announcement or post mortem review published, whatever the source was.


Don’t make the mistake of assuming that this web stuff is simple, that it’s all served from one server, or that two people will receive even remotely the same data served to them, too.

That is a common phishing technique that you may see on a website, email, or even text message. Review this link below to help identify these scams. Calling a number that is given to you is not a good idea. If you want to contact a company, go to the web page of the company to find the contact info. Simply searching for a phone number using Google may bring up a fake number as scammers pay Google to have their search results show at the top of the list.
