From December 2023 to the present, QiAnXin Threat Intelligence Center observed that a ransomware written in rust language is very active on the Chinese Internet, and a large number of machines in China have been ransomed, with up to more than 20 victimized units only in the terminals of government and enterprises, which the researchers call Rast ransomware.
After a long time of tracking, QiAnXin Threat Intelligence Center have captured three versions of Rast ransomware, and the versions are still iterating. rast ransomware has a very special logic: after the ransomware is completed, it will upload the machine name and unique identifier of the local machine to the remote mysql database. Through reverse analysis the research team got the mysql database account password and statistics of victims in the database, and found that in just ten months more than 6,800 terminals were controlled.
