Lumino_Ransom Ransomware Contains Bilingual Ransom Note

Lumino_Ransom is a new ransomware variant discovered in late October 2022. It does not belong to any of the big families of ransomware clones.

Lumino will encrypt the system and scramble files on it. Once encrypted, files receive the ".lumino_locked" extension, attached after their original one. This will turn a file named "document.docx" into "document.docx.lumino_locked" once it gets encrypted.

To make things more confusing, Lumino_Ransom does two unusual things. First, the ransomware creates four hundred blank, zero-byte files on the desktop, naming them Lumine1 through Lumine400. Additionally, the ransomware does not dump its ransom demands inside a file. Instead, it opens a Notepad window and what is likely a keystroke script types out the ransom note in real time, in front of the victim's eyes.

The full ransom note is in English and French and goes as follows:
