Technical Details

The worm is a PE executable file 393 kilobytes long, written in Delphi. The worm's file is not packed.

Installation to system

When run, the worm copies itself as FUNNY.SCR file to Windows folder and also as STARTWIN.EXE file to the startup folder of a current user. Then the worm creates a startup key for its SCR file in the Registry:

[HKCU\Control Panel\Desktop]  "SCRNSAVE.EXE" = "%WinDir%\funny.scr"   

The worm creates the M.TXT file in the root of C: drive to verify that it has suitable access rights.

Spreading in e-mails

Before spreading the worm scans certain files on a hard disk to harvest victims' e-mail addresses. The following files are scanned:

Deleted Items.dbx  Inbox.dbx  Outbox.dbx  C:\Program Files\Yahoo!\Messenger\ypager.log  C:\Program Files\Yahoo!\Messenger\ypager2.log   

To send e-mails the worm uses either the default user's SMTP server or the hardcoded list of SMTP servers:   

The worm sends messages with different subjects, body texts and attachment names. Here's the list of possible e-mail subjects:

Poza de la mare  Antivirus  Sex in camin  Faza cu camila  De ce mor mai repede curiosii...  Antimanele   

Here's the list of possible e-mail body texts:

Ti-am trimis ultima poza de la mare. Asta e?  Asta e ultimul antivirus. Ar trebui sa rezolve toate problemele.  Ioana, sex in grup in camin. Cred ca o stii si tu ;)  :)))))))  Nu deschide acest mesaj! E numai pentru persoanele prea curioase!  Daca sunteti nu mai suportati manelele la servici, tramvai, taxi, metrou, etc., trimiteti acest mesaj la toti prietenii dvs. !  Va multumesc (din suflet).   

Here's the list of possible worm's attachment names:

scan_picture_0001._JPG.exe  antivirus.exe  ioana_divx._AVI.exe  camila.exe  curiosii.exe  antimanele.exe   

The worm fakes the sender's e-mail address. It can be one of the following:  Ionut  

The worm has a nasty payload. When it scans files on a hard disk, it checks the files with the following extensions:

.mp3  .wma  .avi  .wav  .mid  .midi  .asf  .mpg  .mpeg  .jpeg  .jpg  .bmp  .rar  .zip  .ace   

If these files contain any of the following strings in their names, they are deleted from a hard drive:

Liviu Guta  Liviu_Guta  Nicolae Guta  Nicolae_Guta  Copilul de aur  Copilul_de_aur  adi de la valcea  adi_de_la_valcea  adi de vito  ady de vito  florin salam  florin_salam  adrian & camy  stana isbasa  adrian cm  adrian copilul minune  adrian_copilul_minune  alina si costi  copilul de aur  dani de la deva  gabi din buzau  gabi de la giulesti  liviu pustiu  guta jr  guta & sorina  printesa ionela  don genove  jean de la craiova  cristian gusatu  ovidiu mititelu  sorinel pustiu  lucian seres  mihaela minune  minodora  n. guta  n.guta  nico cu carbon  nico_cu_carbon  sile dorel  vali vijelie  carmen serban  petrica cercel  nicu paleru  cata boss  liviu_guta  stefan de la barbulesti  florin peste  liviu cu mirela  sorina & florinel  puiu codreanu  catalin de la buzau  daniel dinescu  relu pustiu  victor spaniolu  vali raicu  adi caval  carmen dobre  sorinel copilu de aur  as da zile de la mine  sunt seful vostru pana mor  chefdechef  chef de chef  dusmanii mei  plange sufletul  jumatate tu, jumatate eu  ce le-nnebuneste pe femei  sa cante manelele  manele   

However this routine is quite buggy: files with .AVI and .WAV extensions are not deleted at all, some files with the above given names are not deleted either.
