In the past few days, while browsing legitimate sites with my iPad, my browser is being redirected to another site and asked me if I want to update adobe flash player. This is strange since iPad doesn’t even support flash. Judging from the url, this is clearly a malicious site. The problems seems to occur only when I run Safari but not Chrome. How do I stop it? Was my keychain compromised? I never jailbreak my iPad or anything so I don’t know how this happened. I have iPadOS with the latest update.
