This latest one is particular enough to be worth mentioning, as the subject line sports the name of one company and the message is signed with the name of another:
The email body contains the usual "you weren't at home, print this receipt to claim the package" message and urges users to download the attached file - in this case an executable masquerading as a Word file and hiding in a zip file.
The file is, of course, a piece of malware that deletes the original file, creates hidden files and makes network connections.
"These infection files have been linked to ransomware, in this case something called 'Wheelsof' and you may well find yourself locked out of your PC if unfortunate enough to fall for this one," Chris Boyd warns.
I understand that spotting spelling or grammar mistakes in fake messages might not be some users' forte, but I wonder just how many of them would spot a glaring mistake such as this one.
