While monitoring attacks targeting MS-SQL servers, AhnLab SEcurity intelligence Center (ASEC) recently identified cases of the TargetCompany ransomware group installing the Mallox ransomware. The TargetCompany ransomware group primarily targets improperly managed MS-SQL servers to install the Mallox ransomware. While these attacks have been ongoing for several years, here we will outline the correlation between the newly identified malware and previous attack cases involving the distribution of the Tor2Mine CoinMiner and BlueSky ransomware.

BlueSky Ransomware is a modern malware using advanced techniques to evade security defences. It predominantly targets Windows hosts and utilizes the Windows multithreading model for fast encryption.
