Process of Alina POS RAM Scraper.
Once executed, it gets installed on the user's computer and checks for updates. If an update is found, it removes the existing Alina code and installs the latest version. Then, for new installations, it adds the file path to an AutoStart runkey to maintain persistence. Finally, it adds java.exe to the %APPDATA% directory and executes it using the parameter codice_1 for new installations or, codice_2 for upgrades.
Alina inspects the user's processes with the help of Windows API calls:
Alina maintains a blacklist of processes, if there is no process information in the blacklist it uses OpenProcess() to read and process the contents in the memory dump. Once the data is scraped Alina sends it to C&amp;C servers using an HTTP POST command that is hardcoded in binary.
