Cerber ransomware kills database connections to access important data
In order to encrypt some of the most important data stored on computers and servers, the Cerber ransomware now tries to kill processes associated with database servers.
The goal for ransomware programs is to affect as many valuable files as possible in order to increase the chance that affected users will pay to have them restored. For consumers these files are things like personal photos, videos, documents and even game saves, but for businesses, its usually data stored in databases.
The problem for hackers is that write access to database files can be blocked by the OS if they’re already being used by other processes, which prevents the ransomware program from encrypting them.
