It looks like the account of Suzie Hix (Suzie@nomow.co.uk) has been hacked and is sending viruses to everyone they have communicated with in the past.
Luckily the exchange server at nomow.co.uk seems to have filtered out the attachment rendering the mailout inert. I don’t have a sample of the payload.
NoMow informed me that they are aware and think they have prevented further access.
This is very similar to the recent “floorplanz” hack.
