Malware type WORM
Spreading mechanism EMAIL
Summary None



When run this worm will copy itself to the Windows System directory using the file name [SYSTEM]i1ru54n4.exe. It will also extract and install two other files:[SYSTEM]go54o.exe [SYSTEM]ii5nj4.exe These are additional components of the worm. GO54O.EXE (24064 bytes) contains the main worm functionality, as well as a backdoor. II5NJ4.EXE (1536 bytes) is a program that loads GO54O.EXE as a DLL.GO54O.EXE installs a Mutex called imain_mutex to avoid being loaded twice.Registry keys created by the worm:HKCUSOFTWAREWinword port = [listen port] HKCUSOFTWAREWinword frun = 1HKCUSOFTWAREMicrosoftWindowsCurrentVersionRun rate.exe = [SYSTEM]i1ru54n4.exeShare/P2P propagationThis worm differs from the previous in that it will copy itself to local and shared network drives. The worm looks for folders containing the string "shar" and copies itself into those folders as:Microsoft Office 2003 Crack, Working!.exeMicrosoft Office XP working Crack, Keygen.exeMicrosoft Windows XP, WinXP Crack, workingKeygen.exePorno Screensaver.scrPorno, sex, oral, anal cool, awesome!!.exePorno pics arhive, xxx.exeSerials.txt.exeWindown Longhorn Beta Leak.exeWindows Sourcecode update.doc.exeXXX hardcore images.exeOpera 8 New!.exeWinAmp 5 Pro Keygen Crack Update.exeWinAmp 6 New!.exeMatrix 3 Revolution English Subtitles.exeAdobe Photoshop 9 full.exeAhead Nero 7.exeACDSee 9.exeNote: Folders containing the word "shar" often belongs to file-sharing programs such as Kazaa, Imesh etc. and this enables the worm to spread via P2P software like this as well.Email propagationThe worm contains its own SMTP engine and will send itself to addresses found on the local computer. These addresses are picked from files of  type  .wab, .txt, .htm, .xml, .dbx, .mdx, .eml, .nch, .mmf, .ods, .cfg, .asp, .php, .pl, .adb, .tbb and .sht. Note: Mails may have fake FROM: addresses. "You have sent a virus" warnings from mail scanners are usually not correct. Mails subjects are composed from the following:Hokki =)Weah, hello! :-)Weeeeee! ;)))Hi! :-)My Name is FrenkgroomFotografPhotoalbumMy photoalbumMyphotosMy photosMy beautiful personbeautifulWau... beautiful (-:Gallery photoscarolineKatrinakleopatraCaitieMary-AnneLisaBad girlJulieAlineAnnaBarbiKatrinaJuliMaryMandySararebeccaJammiekateAudrastacyRenaKelleyTammyello! =))Hey, ya! =))^_^ meay-meay!^_^ mew-mew (-:Hey, dude, it’s me ^_^ :PPossible mail bodiesArgh, i don’t like the plaintext :)¨Fell free to chat with me I accept all ages.Don’’’’t worry Idon’’’’t bite........hope to hear from you soon!If you are going to make me cry, at least be there to wipe away the tears *Right now the worst thing for you to tell me that I can find someone better than you, especially when you are all I wantYou don’t know what you’ve got till it’s gone *You hurt me more than I deserve, how can you be so cruel?
