RapidFAX Customer Service
This message, which purports to be from online fax to email service RapidFax, claims that a fax has been received and can be viewed by opening an attached file. The email includes a list of details about the supposed fax along with the RapidFax logo and links to associated websites.
However, the email is not from RapidFax and the attachment does not contain a fax as claimed. In fact, the attachment contains a .zip file that harbours a trojan.
Unzipping the attached file reveals a malicious .exe file. If the user proceeds to open this .exe file, the trojan will be installed on his or her computer.
Typically, such trojans can make contact with remote servers controlled by cybercriminals, harvest sensitive information from the compromised computer and download further malware.
If you receive one of these emails, do not open any attachments or click any links that it may contain.
