I wish to express my gratitude for the prompt responses and valuable insights shared. I would like to clarify the nature of the alert I received on my iPhone. This alert was generated by a built-in feature that detects if credentials stored in the password manager are part of a data leak. The specific message conveyed was:
"This password appeared in a data leak, which puts this account at high risk of compromise. You should change your password immediately."
In response to the situation, I would like to emphasize the following points:
I have always utilized unique and distinct passwords for each of my online accounts, including my Cloudbet account.
The email address in question, which received this alert, has solely been used for the purpose
Doesn't that mean it's your password only, and not necessarily your Cloudbet account? I'm not familiar with the iPhone thingy (never used one), but I reckon they just used a large text file of hacked passwords then hashed it and checked if it matched your account (wait isn't that basically brute forcing and illegal?). I reckon you can just change your account password imo.
In reference to Curacao, I've done my fair bit in the past and they're bad, yes but reputable nonetheless (I still have no idea how that happened). In case of breaches like this though, I don't think Curacao has any intensive background checks on casinos under their license, they're usually just submissions of legal documents and permits plus some reputation checks. Not necessarily the best place I'd use as a reference if a site is data secure or not.
