Bitcoin - The Currency of the Internet

If you use Electrum, in case you get a error message that tells you to update please ignore (ongoing phishing attack).

Details here: https://github.com/spesmilo/electrum/issues/4968

copy paste from SomberNight in the github issue:

TL;DR: There is an ongoing attack against users where servers raise exceptions when a client broadcasts a transaction; in this case the error text is displayed as is in the client GUI. The attacker has spawned lots of servers on different /16 IPv4s to increase his chances of being connected to. The error messages are trying to get the user to download and install malware (disguised as updated versions of electrum).`

apparently previous Electrum versions allow richtext in error messages sent by the server, so the upgrade warning might look legit to people...

Always remember to verify pgp / gpg signatures of bitcoin software you install.
