Червь является приложением Windows (PE EXE-файл), имеет размер около 167КБ, упакован UPX. Размер распакованного файла около 200КБ.

Инсталляция

Также червь копирует себя в системный каталог Windows с именем:

C:\WINDOWS\SYSTEM32\sqlssl.doc      .exe
Затем червь создает запись в системном реестре:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Xuy v palto]
