Members of the public are randomly emailed with false “spoofed” emails made to look as if these emails were sent from SARS, but are in fact. If you think you've been the victim of a spoofing scam, you can file a call blocking tools and check into apps that you can download to your mobile device. Typically, authentic institutions don't randomly send you emails with attachments, but instead direct you to download documents or files on their own website. spoofing file download

Download dialog spoofing using Content-Disposition header

Description

Andreas Sandblad of Secunia Research demonstrated a method to spoof the download dialog for saving files by supplying a Content-Disposition header with a different extension than the extension visible in the link and download dialog. Users could be tricked into downloading a safe-looking file such as a JPEG image and have it actually be saved with an executable extension.

Windows hides file extensions by default. If the user did not notice the incorrect icon they might at some later time double-click on the saved file and execute it instead of having it open in the expected media application.

Workaround

Use caution when downloading files from an untrusted site, un-hide file extensions on windows.
