Hello.
We have found one possible bug with lobstr.co wallet.
When we access lobstr.co federation server to retrieve public key for the given Federation address, it return any random Stellar Public Key for the federation address which does not exists.
Example:
curl "https://lobstr.co/federation/?q=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa@gamil.com*lobstr.co&type=name"
{"stellar_address": "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa@gamil.com*lobstr.co", "account_id": "GBVVZ36RYDM24QM26D6ROYYUYEZ3IUDNUCVGNCF6JF5ZCXK4EYCRKL2J"}
Do not use lobstr.co wallet for federation address resolution until this bug is fixed.
Regards.
