Hi,
we faced a flood of fake DHL shipping notification mails recently. The majority of mails contained a link and a PDF with the same link leading to a malware infected file. A couple of the reported mails I received by our employees contained a PDF where the malware code was already embedded in the PDF itself.
But strangely in a minority of emails (around 2 out of 100 reported ones) I found some hidden code in the mail body. The code was kept in super small font size and the color was set to white. On the first look you could not see that. Here is how it looks:
I copied the code into a TXT file and attached it to this post. The file name is "hidden code.txt".
Does anyone have a clue about what that code might be?? Anyone out there seen this kind of thing already before?
thanks
Martin
