When run, the worm displays a fake error message:

Can't find a viewer associated with the file

and creates one of the following mutexes:

|MuXxXxTENYKSDesignedAsTheFollowerOfSkynet-D
'D'r'o'p'p'e'd'S'k'y'N'e't'
_-oOaxX|-+S+-+k+-+y+-+N+-+e+-+t+-|XxKOo-_
[SkyNet.cz]SystemsMutex
AdmSkynetJklS003
_-oO]xX|-S-k-y-N-e-t-|Xx[Oo-_

then creates the following files:

%SYSDIR%\sysxp.exe -- worm executable file

where %SYSDIR% is Windows System directory (eg. C:WindowsSystem, C:WinNTSystem32)

%SYSDIR%sysxp.exeopen -- worm copy with some garbage appended

%SYSDIR%sysxp.exeopenopen -- worm zipped (may be password protected) or the worm dropper with .cpl extension

and creates the registry key:

[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun]

with the value:

"key"="%SYSDIR%sysxp.exe

The key above is created ten times per second, so deleting it will not help unless the process (sysxp.exe) is killed.

The worm tries to remove the following registry keys:

HKCUSoftwareMicrosoftWindowsMy AV
HKCUSoftwareMicrosoftWindowsone Labs Client Ex
HKCUSoftwareMicrosoftWindows9XHtProtect
HKCUSoftwareMicrosoftWindowsAntivirus
HKCUSoftwareMicrosoftWindowsSpecial Firewall Service
HKCUSoftwareMicrosoftWindowsservice

HKCUSoftwareMicrosoftWindowsPandaAVEngine
HKCUSoftwareMicrosoftWindowsNorton Antivirus AV
HKCUSoftwareMicrosoftWindowsKasperskyAVEng
HKCUSoftwareMicrosoftWindowsSkynetsRevenge
HKCUSoftwareMicrosoftWindowsICQ Net
To mail itself, the worm searches the local hard-disk for e-mail addresses inside files with the following extensions:

.wab, .txt, .msg, .htm, .shtm, .stm, .xml, .dbx, .mbx, .mdx, .eml, .nch, .mmf, .ods, .cfg, .asp, .php, .wsh, .adb, .tbb, .sht, .xls, .oft, .uin, .cgi, .mht, .dhtm, .jsp

and uses its own SMTP engine to resolve the target mail server and to send mail to it, skipping e-mail addresses that contain:

@hotmail, @msn, @microsoft, rating@, f-secur, news, update, anyone@, bugs@, contract@, feste, gold-certs@, help@, info@, nobody@, noone@, kasp, admin, icrosoft, support, ntivi, unix, linux, listserv, certific, sopho, @foo, @iana, free-av, @messagelab, winzip, google, winrar, samples, abuse, panda, cafee, spam, @avp., noreply, local, root@, postmaster@

Also the worm copies itself to directories that have shar in their names (for instance the P2P shared folders) with one of the following names:

Microsoft Office 2003 Crack, Working!.exe
Microsoft Windows XP, WinXP Crack, working Keygen.exe
Microsoft Office XP working Crack, Keygen.exe
