Cyber-attack against CEI mail server

On Monday, November 29^th, CEI mail server was the target of a cyber-attack that sends emails ostensibly from CEI senders to random recipients, generating a fake response to legitimate emails.

In case you received a reply message from a CEI sender to an email that you did not expect a response to, be very careful when opening it.

If you use Outlook as your mail client, the following wording is a clue:

<This item contains active content. Open the item to read its contents>

The content of the message, looks like the following (we have only examples in Italian):

We have neutralized the threat: if you received the above messages, please delete them.

Thanks for your cooperation.
