If the user executes the worm by double-clicking on the attachment, the worm is installed on the system, saving a copy of itself to the Windows system registry. The worm then amends the registry so that the copy saved on the directory is run during every system startup.

Propagation

Once installed on the system, the worm searches through all files on local and removable drives for e-mail addresses. The worm is able to search through all files EXCEPT:

.avi

.mov

.wmv

.mp3

.wave

.wav

.wma

.ogg

.vob

.jpg

.jpeg

.gif

.bmp

.exe

.dll

.ocx

.class

.msi

.zip

.7z

.rar

.jar

.gz

.hxw

.hxh

.hxn

.hxd

The worm then spams copies of itself to the harvested e-mail addresses.

Data Stealing

While active, whenever a user attempts to log into an Internet banking website, the worm is able to log and store the password entered.

A very large number of banks, in numerous countries around the world, are targeted by the worm. The full list of banks are:
