Google has introduced a new feature called Restore Credentials which saves your app login info and restores it seamlessly on new devices.
They should enable ability to do local backups.
No thanks, sounds like security and privacy nightmare.
The part about “no user interaction required” doesnt feel right secure.
Especially as it is stored at google servers, it says it is encrypted but it is encrypred using keys that google has access to as they are unlocked with you logging in into google account.
Aren’t they encrypted with the phone’s lockscreen password? You very much need that to restore cloud backups. Not that it has much value if you’re a 4 digit PIN person…
Anyway, I can use a search engine:
Some data is further encrypted with your device’s screen lock. Photos and videos stored in Google Photos, and MMS media received from your carrier are not encrypted by your device’s screen lock.
Well, what is some data?
Anyway, I wish for something universal for offline backups. I mean, without root.
It’s only stored with Google if cloud backup is enabled it says. Otherwise, the keys are transferred along with all the other data directly from device to device when switching.
it says it is encrypted but it is encrypred using keys that google has access to as they are unlocked with you logging in into google account.
First it uses lock screen password, so google do not have access to this password.
Even if your lock screen is unfortunately your Google password, I think proper authentication protocol do not send your password to Google to authenticate, but only the hash, which cannot be reverted to derive your password.
Obviously, the above is assuming that Google is not malicious. Otherwise it can just use play service, which is privileged and closed source, to get all your data. If your threat model including Google itself trying to steal your key, you will probably need to install a trusted rom or use iOS (however, apple and the rom developer can also steal your key).
assuming that Google is not malicious
Previously they would need to push malicious code to your device to steal your login data, that is a risk that someone would do reverse engineering on that and expose it, now they will have the data on their servers and they can abuse it any time they want, I doubt they will use it to login as you, but they will use it as metadata to connect all your accounts for marketing.
proper authentication protocol do not send your password to Google to authenticate
That is not true for 99% services including google. Google have a plain text password at the time you are logging in, they just store hashed+salted version in storage.
(Almost) No website (or app) is hashing the password before sending it to server, so if you hack the login screen you can dump RAW passwords anytime.
You are right. I have done some research, it seems most people think that client side hashing is unnecessary in an HTTPS setting.
That is my misunderstanding.
that sounds… vulnerable.
is that why Apple devices perpetually get broken into and all the pictures/info shared?
because their login information is held by a third party?
are there any recent cases? with recent i mean, not back when jennifer lawrence boobie pics leaked
I feel like I read a new article with Apple IDs being leaked every year.
looks like there there have been six major apple data leaks since the 2014 incident you’re talking about, so a major leak based on exploits every year and a half, and then there’s also all the individual articles that pop up with someone saying they received notification that they’re iCloud data or Apple ID was leaked, which I don’t know the frequency of but I see all the time.

seems to happen fairly often.
I think these are different. They mostly find vulnerability in the iOS system as opposed to try to crack the backup system.
I think iOS or Android backup system are rather secure compared to other components because of the following: hacker will also need to break into a cloud drive to retrieve them, which adds extra work; the backup is simple, just bunch of files and a password, apple/google can use standard well-tested encryption to encrypt them.
However, guaranteeing there is no way to break into an operating system, especially with all the features that a modern system requires, is much harder.
yeah, these data leaks are all about break into iOS specifically to access iCloud data and accounts, I don’t know about their backup servers.
If they can get the data up front, why go around the back?
The iCloud leak from 2014 was all leaked login information also, it’s why they finally implemented encryption.
oh but Apple officially says that the 2014 attack was only due to fishing and brute Force attacks.
idk, enforcing encryption directly after that was a good idea, but I doubt they would do it unless it was necessary or vulnerable.
Which 3rd party?
