How Hackers Can Disguise Malicious Programs With Fake File Extensions
File extensions can be faked – that file with an .mp3 extension may actually be an executable program. Hackers can fake file extensions by abusing a special Unicode character, forcing text to be displayed in reverse order.
Windows also hides file extensions by default, which is another way novice users can be deceived – a file with a name like picture.jpg.exe will appear as a harmless JPEG image file.
