I've been looking for ways to avoid files that are masquerading or spoofing their filenames using the Right-to-Left Override Unicode Character from being run or written into my computer (OS is Windows 7). More info on the RLO unicode character here: http://www.fileformat.info/info/unicode/char/202e/index.htm Some malware use the RLO unicode character to spoof or hide their real filenames or file extensions. (Will still be hidden even if 'Hide extensions for known filetypes' is unchecked.) The only info I can find that offers info on how to do this is from the Information Technology Promotion Agency, Japan website: http://www.ipa.jp/security/english/virus/press/201110/E_PR201110.html It advices to use the Local Security Policy settings manager to block files with the RLO character in its name from being run. Can anyone recommend any other good solutions to prevent files with the RLO character in their names from being run or be written in the computer, or a way to alert the user if a file with the RLO character is detected (OS: Windows 7)?
