Is this recent FLOOD of data leaks from Apple iphone security breach?

Thanks Nick, would you be able to explain what was involved, because it's quite a coincidence that these highly secure sites unique passwords appeared in a data leak & these high security site (banking & a country's taxation portal) would be leaked in the same fortnight. Along with a Facebook unique password that was made only 3 weeks ago so can't have been available before that for anyone because it didn't exist. Along with these unique highly secure sites that haven't reported a breach nor listed as a breached company over the last weeks, month nor years, almost all other sites are listed. I've had the same banking password for years because I memorised it - didn't save it anywhere. About a month ago I had to put the password into my phone to use the banking app. This just seems TOO oddly coincidental. So if you can tell me if the security issue allowed unauthorised access on details on my phone then surely the first place hackers would look is in the iPhones "passwords" then it would be handed to them on a plate.

The reason for asking is this is hours of work to change every different password I have (like I said every password is listed not just one or two). I've experience a data leak before & it's corresponded with a company report of breach eventually but this is every different password for almost every site in my password list. Obviously I've now changed all banking / credit card sites- although I usually don't allow my carditis card to be saved - I type it in each purchase. BUT it's still many hours to fix & if the vulnerability was Apple Passwords themselves then that is a whole new level of problems.

Thanks SB

Can some one just tell me if the patched vulnerability could have lead to someone accessing the "passwords" saved in the "passwords" section of my new iPhone SE? This is the question I've now asked 3 times so it would be nice to know the answer to this question. I really think this question would be important for many people actually.

Lawrence , thanks for your answer but I have contacted the Bank & awaiting answer for Government site. I had already checked the "have been pwned" sites & lists of data breaches. If they were listed, then of course I would count this all as extremely bad luck - unique passwords from high security sites & new (few weeks old) unique password from less secure - all being hacked in the same time frame. None of the less secure sites that I use report a recent breach, but for twitter & weirdly my unique password for twitter isn't listed as being exposed! Approximately 40 sites are listed including some for which I've made very unique passwords are reported as in the data leak, but none of theses sites are listed in recent breaches. The Bank had a breach about 6 years ago & hence attempted to improve security since then. So while they all could have been breached in the same time frame it is odd that: 1) they have ALL been breached recently & 2) none are on any breached lists I can find & it happened within days of the recent iOS update for security reasons. Again no-one is responding to the question I keep asking - that is if I couldn't update the "security" vulnerability patch fast enough (as soon as it was reported in the press here) then COULD the "passwords" data on my Apple iPhone have been accessed because they ARE saved on the iPhone? That is why there is a section in the settings called "passwords". This is where the passwords ARE kept. I am not an expert hence why I came to this site, but I also am usually a logical thinker & it just seems too much of a coincidence. 1) Security vulnerability found in Apple iOS, 2) Apple puts out a public warning, 3) suddenly MOST my DIFFERENT passwords for approximately 40 sites, including some with quite high security - including the Country wide system storing Residents' taxation, banking & medical information, have all been breached in the same time frame, 4) YET none are on the publicly available breach lists. (& my bank reports no link to Question Pro either).

Can some one just tell me if the patched vulnerability could have lead to someone accessing the "passwords" saved in the "passwords" section of my new iPhone SE? That would be very helpful for future planning & I'm sure I'm not the only person concerned.
