Glasrats Trojan – More About It
According to Symantec researchers, once the Trojan is executed, it creates these files:
- %AllUsersProfile%\Application Data\update.dll
- %AllUsersProfile%\Application Data\updatef.dll
- %AllUsersProfile%\Application Data\net317rs.dll
- %AllUsersProfile%\Application Data\ovss725y.dll
After their creation, new registry entries will be added as well:
→HKEY_LOCAL_MACHINE\SYSTEM\Select\”Default” = “2”
→HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasAuto\Parameters\”ServiceDll” = “[Malware Path]”
→HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasAuto\”Start” = “2”
Those files will allow for the Glasrats Trojan to update itself. The registry entries will make the malware’s processes to run automatically with each system start. Every Windows Service can be set to have an ”Automatic” start by setting that registry value to “=2”, like it is in the registry keys above.
After these actions, the Trojan will open a backdoor, modify firewall settings, and connect remotely to the following locations:
Through that backdoor, Glasrats may perform a number of malicious actions. Such actions include:
- Sending system information (IP address, computer name and OS version);
- Downloading malware to the computer;
- Uploading files to the remote locations.
Other possible things the Trojan may do are file and command execution and starting an interactive command shell.
