CDS Group (cdsgroup.co.uk) fake invoice spam

This spam email pretends to be from the CDS Group. CDS are a wholly legitimate company and are NOT sending these emails, and their computer systems have NOT been compromised. However, the emails do contain a malicious attachment and should be deleted.

It is trivially easy to fake who an email is "From". That is what is happening in this case. CDS are an innocent victim of whoever is perpetrating this spam run. Please do not take your frustrations out on CDS. CDS have a notice about these emails on their site.

This is a sample email:

Attached is a archive file CDS_241-28195.zip which contains a folder invoice_cdsgroup_799543.xls which in turn contains a malicious executable invoice_cdsgroup_799543.xls.scr which has a very low detection rate at VirusTotal of 3/54.

Automated analysis tools are inconclusive at the moment [1] [2] but I will add more details if I find them.

I received this identical, rather suspicious email and decided to check what this company does before opening the attachment, as I was not expecting an invoice to be sent at that particar time of day; so thanks for the warning - much appreciated and instantly heeded.
