More Information
Troj/LegMir-Y is a password stealing Trojan which attempts to steal password and user information from players of the online multi-player role-playing game, Lineage.
When first run on Win9X the Trojan will first copy the original Windows files rundll32.exe from the Windows folder and internat.exe from the Windows system folder to C:\ then overwrite them with itself.
When first run on Win2K/XP the Trojan will copy itself to the Windows Program Files folder as explorer.exe and create the following registry entry so as to auto-start on computer reboot:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
sysMett1
C:\Program Files\explorer.exe
Troj/LegMir-Y will also drop a helper dll into the Windows system folder as htdll.dll and load it.
Troj/LegMir-Y may attempt to terminate some anti-virus and security related processes.
