The victim who sees the files with .londec extension understands that they are locked and will remain so until he pays the attackers the required amount of money for obtaining a special key that will decrypt the files. Usually, the makers of the Londec ransomware leave a ransom note named ‘_readme.txt’ to users who have infected their computer with this ransomware virus, indicating the required amount of ransom.
