Following on from Yesterdays mass spam run spoofing FedEx where they asked you to click on a link to verify identity, Today has gone back to the old pattern of attaching a zip file and asking you to open the zip file and fill in the documents.
Update 7 February 2014: the malware purveyors are now using a method of adding the recipients details into both the email and the attachment name
The subject normally says: ATTN: Important information
See also https://myonlinesecurity.co.uk/spoofed-british-airways-your-flight-ticket-is-not-activated-yet-fake-pdf-malware/ which carries the same malware as this FedEx spam.
Needless to say, this Fedex Shipping confirmation is not a genuine FedEx email but another one from the current zbot runs which try to drop cryptolocker, ransomware and loads of other malware on your computer. Most of these are using email addresses and subjects that are appropriate for the time of year. Currently many of the emails are either about undelivered packages or invoices or payment advice for online shopping. All subjects that we would expect to receive in emails at this time of year. The other major common subject is Tax returns, where especially in UK, you need to submit your Tax Return online before 31st December each year.
Almost all of these have a password stealing component, with the aim of stealing your email or FTP ( web space) log in credentials. Many of them are also designed to specifically steal your facebook and other social network log in details.
Please read our How to protect yourselves page for simple, sensible advice on how to avoid being infected by this sort of socially engineered malware.

This Fedex Shipping confirmation is another one of the spoofed icon files that unless you have “show known file extensions enabled“, will look like a proper PDF file instead of the .exe file it really is, so making it much more likely for you to accidentally open it and be infected.
All of these emails use Social engineering tricks to persuade you to open the attachments that come with the email. Whether it is a message saying “look at this picture of me I took last night” and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day. Be very careful when unzipping them and make sure you have “show known file extensions enabled“, And then look carefully at the unzipped file. If it says .EXE then it is a problem and should not be run or opened.
