Right-To-Left Override (RLO) Extension Spoofing is a deceptive technique that exploits the Unicode control character U+202E.
This character is typically used for bidirectional text formatting, but it's being weaponized to trick users.
The RLO Character:
The RLO character influences text display, making text appear right-to-left, commonly used in languages like Arabic and Hebrew.
Exploiting File Extensions:
Malicious actors use the RLO character cleverly within file names to manipulate how extensions are displayed.
Example: "invoice.pdf" becomes "invoice\u202Efdp.exe," visually appearing as "invoiceexe.pdf."
The Deception:
Users may see a harmless file when it's actually a dangerous executable.
The ".exe" extension is hidden, luring users into a false sense of security.
