This week's email is all about Covid for all suppliers to declare their vaccination status, but the date is almost 1 year old.
After saving the attachments, it provided a case sensitive password (W485) to extract the ISO attachment into file Invoice_10-12_document_9054.iso. To examine the content of the ISO, I used Linux to mount locally the ISO to view and analyze its content.
Mounting the ISO with Linux:
mount -o loop Invoice_10-12_document_9054.iso /mnt
The ISO contains two files that appear interesting, two files are pictures and two are just random text.
The first file of interest to check out is licentiousness.cmd:
The second file of interest is relaxare.dat file with Virustotal and there was no match, then uploaded the file for analysis with the following results which matched a Banking trojan by Proofpoint and Snort.
