Closing note

Many a times security breaches and attack attempts make use of this hidden nature of the file extension. Attack scripts and code are named in such a way that it include know extension in the file name. For example: abc.pdf.script, will be disguised as a pdf file in the name of abc and rest of the file name extension will not be shown. When the users unknowingly click on this and tries to open these file, the codes get executed which may lead the attack to get triggered.
