An email with the subject of New BT Online bill pretending to come from BT but actually coming from a different domain firstname.lastname@example.org that can very easily be mistaken for a genuine BT email address is today’s latest spoof of a well-known company, bank or public authority delivering Dridex banking Trojan
Update 18 September 2017: a new run of this using BT Business <email@example.com> as sending email address.
They are using email addresses and subjects that will scare, persuade or entice you to read the email and open the attachment.
Remember many email clients, especially on a mobile phone or tablet, only show the Name in the From: and not the bit in <domain.com >. That is why these scams and phishes work so well.
BT has not been hacked or had their email or other servers compromised. They are not sending the emails to you. They are just innocent victims in exactly the same way as every recipient of these emails.

Normally there are between 2 and 4 newly registered domains that imitate Companies House, HMRC, another Government department, a Bank or a message sending service that can easily be confused with the genuine organisation in some way. Some days however we do see dozens or even hundreds of fake domains.
Today’s example of the spoofed domains are, as usual, registered via eranet.com as registrar. This was registered on 13 September 2017 by the criminals
- bt-europe.com hosted on 126.96.36.199 OVH

Update:18 September 2017. New sending domain btsgl.com 184.108.40.206 still hosted by OVH. Emails sent from these IP numbers:
The email looks like:
