Malware. Opera was bought by loan scammers so this doesn’t surprise me one bit.
Edit: comment from an old reddit post:
From Kenya here. When you fail to pay Okash loan on time they will call random contacts on your contact list and tell them to tell you to pay your loan back
This is where Opera is now.
But it doesn’t always point to the destination. Instead, it points to another page that then redirects you to the destination.
Your browser does not know the address of the destination, only the addresss of the middleman tracking webpage.
