Why does Norton deem the Telegram app to be unsafe?

投稿日: 2023-07-01 | 19:48 · 返信 6 · · 翻訳:

I have an iPhone SE (2nd gen) and an iPhone SE (3rd gen) on which both the Telegram app and the Norton 360 app are installed. The Norton 360 app had been installed 24-48 hours when I got the notification (while using Telegram and all other apps were closed) on the 2nd gen iPhone. To this point, I have not received a similar notice on the 3rd gen iPhone. The Norton 360 app was installed while a Norton agent was on the phone with me, walking me through the setup. 

I have used the Telegram app daily (a minimum of 8 hours a day, 7 days a week) for at least 3 years, and I belong to several channels and groups that I interact with the other members of the groups/chats. I am owner of several groups, both public and private.  I have never had reason to believe that anyone has had an unsafe experience when using Telegram.  I posted the attached 3 screenshots in several of my groups to see if anyone else had received an "Unsafe" notice about Telegram.  So far, the response has been "No."

So I would like for Norton to share with me and my fellow Telegram users why Norton recommends that we not use Telegram.  If it is truly unsafe, I need to alert my online friends, but if there is no evidence pointing to a possible security risk by using the app, I don't believe anyone will take this one notification seriously. 

Thank you.

Without knowing the exact wording of the warning, it is hard to say what the issue might be. If you post the screenshots here it will help diagnose the issue.

As you are only seeing this on the older phone, one thing that might be involved is the iOS versions on the two phones. I believe the older iPhone SE (2nd gen) is stuck on iOS 15.x.x while the 3rd gen SE would be on iOS 16.x.x.  What Norton may be detecting on the older OS is some security issue with the older iOS that has since been resolved in the latest iOS versions.

(I may have replied to myself before, so I'm trying this again.)

I did post screenshots originally, but they may be still in moderation?  Will post again.

Both phones are 16.5.1

There is nothing in your screenshots that indicates this is a warning about the Telegram app. The warning is about a web page that an app you are using, or if you are using Safari to view some web site, that appears to have a malformed ad. The URL definitely looks like an ad. If it were the Telegram app itself accessing online content, the URL would include something like telegram.com. Why did this only show on one of your devices? The ad services rotate ads all the time, and it depends on when you access the app or web site as to what ads you would get delivered with the web content.

Best not to Allow access to site when Norton warns you. Even though iOS is a well protected OS, and most malware is aimed at Windows systems, I see no reason to take any chances.

Thanks for the explanation.  

I was looking at my Telegram list of chats/groups I follow, when the warning popped up at the top of the screen.  I attempted to get a screen shot, but the warning disappeared too quickly, so I had to look for it in the Notification Center, and that is where I took the screen shot.  

As I may have said previously, I rarely ever (and definitely not since the hacking incident a few weeks ago) use either iPhone for surfing the web (Safari), so I'm not sure where the ad would have come from.  TG does not insert ads into feeds/chats (the way twitter & FB do). Is there any way to reverse the "allowing" of the ad that I did? 

It would be very helpful, especially for non-techie ppl such as myself, for alerts/warnings to avoid a particular website to actually include the name/url of the website/ad to avoid, don't you think?

To reverse the permission you granted, you will need to uninstall 360 from the phone, restart the phone and reinstall 360. Unfortunately, in iOS there is no option to just remove an app's data. Reinstalling takes care of that.

As to where it came from, I can only suggest that something in one of the messages you received had some unwanted code in it that tried to access the ad. Also in one of your images it shows a Twitter notification. If Twitter was running in the background at the time you got this warning, it could have come from there.
