Envoy 2.3.7: screenshot protection on the seed QR screen and a new onion address for Passport Prime verification

Foundation has released Envoy 2.3.7, continuing the preventive security work started in 2.3.6. The Passport Prime security check has moved to a new onion address and gained an additional layer of verification; behavior where screenshot protection did not persist when switching from seed words back to the seed QR screen has been fixed. The vendor recommends that all users update.

Actions to take

Envoy users: update to 2.3.7 through the download page or app store; the vendor warns that App Store and Google Play review may cause a substantial delay before the update appears. On Android, you can optionally verify the binaries using the vendor's guide (links in the post). If the seed QR screen on a vulnerable version may have appeared in a screenshot or screen recording, treat the seed as compromised: create a new wallet in a trusted environment, write down and verify the backup, transfer funds and wait for confirmation, then retire the old wallet.
