A few days ago Thunderbird downloaded another email with a .doc attachment, and today I got another one. One was sent from an email address ending in .es which I presume would be Estonia, and the other one looked Chinese. Both emails said the attachments are invoices, and neither contained any of my personal information other than my email address. I also have Thunderbird set to block remote content.
Out of curiosity I saved the .doc attachments to a USB stick (that the computer thinks is a CDROM - it's an old USB stick), and the 'find' command on my Linux terminal which determines the file type, says, about the one I received a few days ago:
al@my_desktop_pc:/media/al/CDROM$ file Copy1935-12.doc Copy1935-12.doc: Composite Document File V2 Document, Little Endian, Os: Windows, Version 6.1, Code page: 1252, Author: I, Template: Normal.dot, Last Saved By: I, Revision Number: 2, Name of Creating Application: Microsoft Office Word, Total Editing Time: 03:00, Create Time/Date: Mon Oct 20 11:29:00 2014, Last Saved Time/Date: Mon Oct 20 11:32:00 2014, Number of Pages: 121, Number of Words: 46463, Number of Characters: 264842, Security: 0I have other Word documents that I created myself in Windows on this computer, and the output of the 'file' command for them is similar to the above.
The output of 'file' for the one I received today, is:
al@my_desktop_pc:/media/al/CDROM$ file AG7005208AU.doc AG7005208AU.doc: Microsoft Word 2007+I clicked on the first one at the time after reading the output of 'file' and it opened in Libre Office, but just looked like a bunch of jumbled characters with no spaces between them, most of which were upper-case letters. I haven't tried opening the other one, even though the computer says its a Microsoft Office 2007 document, just in case it isn't.
I'm curious to know why anyone would go to the trouble of sending me an email with an attachment that doesn't contain any information, and claiming that it's an invoice? Is it possible that these aren't Microsoft Word documents, even though the computer says they are? I'm particularly suspicious of AG7005208AU.doc because the output of 'file' is simply 'Microsoft Word 2007+' rather than the more detailed output that I would have expected.
All of the above were sent to the same email address, which is provided by a business rather than a residential ISP, which I have had for many years and regard as my main email address for personal use, and which I have managed to keep relatively free of spam. But I recently set about clicking on the 'unsubscribe' links in all of the spam emails that I was receiving, and wonder if doing so could have alerted someone with nefarious intentions that this email address is being used?
Finally, other than changing my email address, or logging into the server to access my email instead of downloading it with Thunderbird, is there anything I can do to stop these emails being downloaded?
