Using a phishing email, the bad guys try to trick you into downloading a file attachment named “ReadMe_knl.txt”. Typically, files ending in .txt are plain text documents that can be opened in any text editing software. But in this case, the cybercriminals use a trick called Right-to-Left Override (RLO) to reverse part of the file name.
The true name of the attached file is “ReadMe_txt.lnk.lnk”. It is not a plain text document, but actually, a command that instructs your computer to download the bad guy’s malware. Once the malware is installed, cybercriminals have complete access to your system. They can access everything from your browser history to your cryptocurrency wallet and they can even take photos using your webcam.
