Antiman is an email worm written in Delphi. The most probably origin of this worm is România. The worm has its own SMTP engine to send emails. The worm harvests victims' email addresses from different files on a local hard drive.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
The worm is a PE executable file 393 kilobytes long, written in Delphi. The worm's file is not packed.
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.
Before spreading the worm scans certain files on a hard disk to harvest victims' email 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 emails the worm uses either the default user's SMTP server or the hardcoded list of SMTP servers:
mail.iasi.rdsnet.ro smtp.dnt.ro scentra.dntcj.ro relay-1.dntis.ro mail.easynet.ro relay1.România.eu.net mail-relay.eu.net smtp.fx.ro ns.matco.ro mail.mailbox.ro mx.kappa.ro mx2.kappa.ro mx1.pcnet.ro mail.rdsnet.ro mail.rdslink.ro tag.starnets.ro mail.totalnet.ro relay.totalnet.ro mail.xnet.ro mail.remote.xnet.ro mail.remote1.xnet.ro mail.pcnet.ro smtp.xnet.ro smtp.home.ro mail.home.ro relay.n0i.net omega.tuiasi.ro hal.cs.tuiasi.ro
The worm sends messages with different subjects, body texts and attachment names. Here's the list of possible email 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 email 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 email address. It can be one of the following:
alexandra@yahoo.com ionut@yahoo.com mariana@yahoo.com alice@yahoo.com bia@yahoo.com Ionut Popovici@xnet.ro Georgiana@fantasy.ro office@bitdefender.ro antimanele@antimanele.go.ro
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.
