More Information
Troj/Riler-H is a backdoor Trojan for the Windows platform.
Troj/Riler-H spies on network traffic on the infected computer. The Trojan will relay certain types of network traffic to a remote site. Troj/Riler-H has a backdoor component that will connect to a remote site and await backdoor commands.
Troj/Riler-H may arrive by email as a CHM file with the following subject line:
east.turstan
When opened, the CHM file extracts an HTML script named Remembering the victims.htm, and drops and runs an executable with the filename hh.exe
Troj/Riler-H copies the extracted executable to the Windows folder with the filenames iefxtray.exe and svchost.exe, and in order to be able to run automatically when windows starts up sets the registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
IefxTray
IefxTray.exe
