Anyone else getting emails of "invoice Payment Confirmation" from
info@cloudhashing.com ?
I ask because I got 2 of those today, with an attachment called invoice_773.jar
If you get such an email, obviously, don't open the attachment.
People reported receiving such e-mails "from" bitmine.ch and Bitmine itself warned against these e-mails too.

It's an attack directed at customers of some Bitcoin companies. The jar attachment is malicious.
Edit: There are similar e-mails disguised as originated from Cointerra, directed to Cointerra customers.
It looks like these companies databases were hacked, because how the sender knows who is which customer?
