Not trusted certificate adding onto my iPhone randomly

Hello,

2 days ago a first untrusted certificate was added to my iphone. This happens every night overnight basically. I put my phone into the do not disturb sleep mode and airplane mode and I keep WiFi on in case I get a notification. Every morning when I unlock my phone I get a notification “certificate wasn’t trusted” and a certificate pops up which is a random, for example from Massachusetts US (I'm from Europe) and there is a weird domain. I have no apps installed which could give me this pop up. Also I have no profiles installed and I have a clear calendar. Last thing, under every certificate pop up it says an expiry date. How do I delete it? Is my phone under a security risk? It’s my personal phone, not a work one nor a school one.

iPhone 14 Pro, iOS 18

If you feel an unauthorized person/app is remotely using, controlling or monitoring your device, then that is possible only if you have done one or more of the following Don'ts...

Don't hand over an iPhone to kids or to a stranger without Enabling Guided Access
Don't share Apple IDs
Don't Jailbreak
Don't share sensitive information pertaining to your device
Don't give in to Phishing
Don't plug in your device in Airports and Public places through third-party cables and trust the device. Beware of Juice Jacking. (Especially in India)
Don't leave your iPhone unlocked and unattended in public places like offices, schools, malls, etc.

If one of the above is true then quickly change the Apple ID Password and Return iPhone settings to their defaults.
