QR Miniapp Update

Earlier today, an attacker stole credentials from the QR miniapp and sent notifications from their apps. Users were sent to a different miniapp and encouraged to buy a fake token for $3.  

The QR team fixed this and reimbursed all users.

Shoutout to the QR team for being very quick to respond. There is no other compromise of Farcaster wallets and your funds are safe. 

What is Farcaster doing to prevent this?

Our transaction scanning prevents dangerous “send me all your money” attacks. That’s why the damage was limited to a $3 buy. 

We are also limiting miniapp notifications to redirect within the same domain. The attacker would have to compromise many more parts of the QR miniapp to pull off this attack again.

What can I do to stay safe?

If an app is asking you to do something that it normally does not, like buying a new token or claiming an airdrop, check the apps home page or the author’s page to see if it is legitimate before taking the action. If there is some doubt, ask the author over DM or in the feed before taking the action.

Mini app developers: please take care to securely store your app's notification tokens! They are sensitive credentials, and if you leak them, it's possible to impersonate your app. 

If you're not sure about storing tokens securely and want a simple and secure option, consider @neynar's managed notifications service.

(We will also build some better self-service tools to revoke your domain association and rotate tokens)

Fr really easy to mess this up without realizing. Glad Neynar’s got a safer option for folks who just want it to work.

idk if GitHub charges for this https://docs.github.com/en/code-security/secret-scanning/secret-scanning-partnership-program/secret-scanning-partner-program
