Any updates to this issue? I think it would be good to have on Mobile, at least on Android, maybe iOS, since this feature is on Desktop. With the ability for users to turn it off of course. I for one would have it on just to be on the more secure side.

Hi there @OnlinePlayer865 - we are making progress 😄 We're wrapping up this feature on iOS (see https://github.com/brave/brave-ios/pull/1339) and are looking to merge soon (iOS product version 1.19?). We can then look at doing this on Android after taking care of some other priority work. I believe @jumde would be able to look at this in the next few months. Thanks for your patience! 😄

Perfect! Didn't think to check the iOS page. Thank you for the info!

As mentioned in the security review, we decided against having our own implementation and went with Apple's built-in one.

For Android, we could either reuse the desktop implementation (this is what Firefox does on Android) or go with the SafetyNet API.

Any progress on this ? Brave still has no safebrowsing working on Android :/

[bsclifton]

We'll be starting work on this soon 😄 Doing some pre-work to see what is needed. We had taken a first step with https://github.com/brave/brave-browser/pull/8664 (which looks correct) but that didn't work

I verified our Android build servers are setting the safebrowsing_api_endpoint value. Will update when I find out more.

Verified PASSED using 1.48.134 on a Google Pixel XL (arm64) running Android 9

Steps:

1. installed 1.48.134
2. launched Brave
3. opened brave://flags
4. set Safe Browsing to Enabled
5. relaunched Brave
6. tapped the 3-dots menu
7. tapped Settings
8. tapped Brave Shields & privacy
9. tapped on Safe Browsing (defaulted to Off)
10. tapped on Standard protection
11. loaded https://testsafebrowsing.appspot.com/
12. went through the Webpage warnings tests

Confirmed I got Safe Browsing warnings for each condition except malware, bad assets (will investigate)
