Over the last couple of days we have seen a new approach to the delivery of malware by email. Instead of the usual malware attachment to an email or a link to an infected file on a compromised or hacked server and website, the bad guys have started to deliver malware via Dropbox
If you look at any of the previous posts on here and see the content of the email, you will find that the bad guys are using identical emails to deliver malware via Dropbox. The Dropbox admin and support are doing their best to keep on top of the attack and are deleting the malware files as quickly as they find out about them or they are reported to them. But there will always be a window of infection between the bots sending out the email with the links and Dropbox being able to remove the files.
The bad guys appear to be doing this, because of the way many mail servers now block attachments or scan and disinfect them to stop users being infected. Unfortunately not enough mail severs do scan and disinfect suspicious attachments and prefer to err on the side of caution and not be aggressive in their approach.
If you see any of these posts from yesterday, it will illustrate exactly what I mean .
Today I am seeing just about every spam email coming with a dropbox link and luckily Dropbox has already removed the content
The bad guys often create one malicious file & use 4, 5 or even 10 different email subjects and contents to entice a user to read the mail, open any attachment or follow the link & get infected. We try to post as many of the current emails here as we can, to alert you to what is a fake, but some just slip past
