This 32bit Mallox ransomware, written in C++, is not obfuscated and its strings are easily readable, thus making analysis simpler.
Analyzing the malware with IDA Pro, the main function calls GetUserDefaultLangID to determine the victim's language ID. This is then compared to IDs of countries in the CIS, to prevent infection in these places, as the local law in Russia is more favorable towards the threat actors who do not distribute malware in the CIS.
Continuing malware analysis in IDA Pro, Mallox ransomware sets up the Active scheme of the victim's power supply to run optimally. It obtains privilege for its execution, and shuts down database services and disables Rancine, a tool that tries to prevent ransomware.
After removal, malware analysis can continue. The Ransomware encrypts HDD, creates a public key, and inserts it into a "HOW TO RECOVER" doc. Then, Mallox ransomware encrypts files and notifies the C2 of a locked target. Finally, the ransomware restores settings and exits.
