I’m getting this alert on my screen when I try to send btc to another address. It’s prompting me to update with a number of windows options and Mac, is this safe?

There's no Electrum v4.0.0 yet!
You're using an OLD version and currently connected to the Hacker's server.

Just disregard that message and you should be safe, do not follow the link provided by the message.

I recommend upgrading your Electrum since versions below 3.3 are vulnerable to that kind of attack and you'll find it hard to connect to a legitimate server.
Download only from: electrum.org Always double-check the URL's characters.

I’m using the latest version of tails, what should I do?

Go to Electrum.org (THE ONLY WEBSITE YOU SHOULD USE) and download the latest version of Electrum which fixes these fake messages exploit. Optionally (but highly recommended), verify the file signatures of the file you download.

The steps to do that can be found on Electrum’s download page.

As other mentioned, it's not safe and you received malicious/dangerous message from server.

Make sure you only download from https://electrum.org (and verify signature of downloaded files with Thomas PGP key). If you still use Tails, you should download Appimage version for your convenience.

I’m using the latest version of tails, what should I do?

Latest version of Tails OS doesn't mean it's installed with latest version of application.

FYI, it's either because :
1. It's conservative OS (prefer security/stability over latest version)
2. Latest version might be incompatible with the OS
3. There's no contributor to upgrade to latest version

There is a very good step by step guide (with screenshots) here that explains how to update Electrum to 3.3.4 on TailsOS


As always, ONLY download from https://electrum.org/#download and verify the digital signatures whenever you download a new version of Electrum
