New Lilith ransomware in early development

July 22, 2022

The Sonicwall CaptureLabs threat research team has observed reports of the launch of a new ransomware family named Lilith.  Lilith ransomware is written in C/C++ and targets 64-bit Windows machines.  Encrypted files are marked with a  ".lilith" extension.  The sample we obtained indicates that it is in early development, as some features reported in the AV community were not present during our analysis.



Infection Cycle:


Upon running the executable, files on the system are encrypted

Restore_Your_Files.txt contains the following message:


During our analysis, no data was leaked from the system.


The .onion link leads to the following Lilith home page:

The following programs are terminated if they are running:


Restore_Your_files.txt is dropped into each directory that contains encrypted files:


Each encrypted file is given a .lilith extension:


We reached out to the operators via the supplied tox ID in the ransom note but received no response.
