Name of the attached infected file is randomly
selected from the list:
Si.exe
ReDe.exe
Disk.exe
Common.exe
UserConf.exe
After the attached file is executed the worm
initiates the infection routine and penetrates the target computer.
Then it gets access to Microsoft Outlook and sends through it its
copies to all the recipients from Outlook address book.
On November 11, 2001 "Redesi" activates
its payload routine and destroys all data on disk C: of the infected
computer. To complete this task the worm writes a command to
AUTOEXEC.BAT file that launches disk formatting. This command will
be executed upon next computer boot up. It is necessary to emphasise
that the payload routine can be activated only on computers having a
short system date conforming to the following formats: "dd/mm/yy"
or "mm/dd/yy".
