Is your feature request related to a problem? Please describe.

Several people have been phished by so-called "multi-auth attack" recently.

The attacker registered a lot of phishing accounts which are similar to exchange deposit accounts or frequent recipients of victims, and added the victims' to the phishing accounts' active authorities with a low weight. When a victim opens the "Send" dialogue, a phishing account will appear in the drop down list of "to" field automatically, if the victim didn't pay attention but clicked the phishing account, funds will be sent to the phishing account.

Note: it only affects key-file (.bin file or local wallet) login mode.

I've tried to reproduce, see screenshots below.

Describe the solution you'd like

A quick workaround is to disable the drop down list temporarily.

Better solutions are to be discussed.
