Attached is a randomly-named ZIP file in the format Invoice_ref-81096454.zip which contains a further malicious script file beginning with invoice_, invoice_copy or invoice_SCAN. Detection rates for these vary [1] [2] [3] [4] [5] [6]. These Hybrid Analysis reports on three of the samples [7] [8] [9] show the script download a malicious binary from:

blablaworldqq.com/80.exe?1
hellomydearqq.com/69.exe?1
hellomydearqq.com/80.exe?1

At the moment, those domains don't seem to be resolving, but if you replace the domains with the IP addresses then it will work. The sites are hosted on the following servers:

51.254.226.223 (OVH, France)
173.82.74.197 (Multacom Corporation, US)


The 69.exe and 80.exe files are actually different, both have a detection rate of 4/54 [1] [2]. Analysis of these files [3] [4] [5] [6] indicates behaviour consistent with ransomware, and these binaries attempt to phone home to the following domains:

conspec.us
tmfilms.net
iqinternal.com
goktugyeli.com
saludaonline.com
