For the last two years or so, attackers have been infecting and reinfecting poorly secured MS SQL servers, booting other criminals' malware from them and exploiting their compute power to mine Vollar and Monero cryptocurrency.

Microsoft SQL Server is a relational database management system/software that can run on computers running any of the most popular operating systems.

The attackers target internet-facing Windows machines running poorly secured MS SQL servers.

Using strong and unique MS SQL user account passwords is a must, and the researchers advise against exposing database servers to the internet.

"If infected, we highly recommend to immediately quarantine the infected machine and prevent it from accessing other assets in the network. It is also important to change all your MS SQL user account passwords to strong passwords, to avoid being reinfected by this or other brute force attacks," they concluded.
