Hi,

something i recently got and what seems to be not recognized by any Antivirus Software. Obviously made in Russia

Have fun while playing with it

Dunno, what it is, maybe a virus or a Trojan. A binary is hidden in a *.ini file. So jar i don't see how the hidden binary is started.

The secret is inside that 1.ini file but you cant strip it without executing the jar file.
Any chances? maybe using eclipse debugging tools?

If you have WinRAR, right-click on the file, select "Extract to Anonim_sms.jar" and you're done. The ini it's just a normal, unpacked PE with .ini extension. Fun thing is, NOD32 didn't detect any threat in the file, but detected J2ME/TrojanSMS.Small.E.Trojan in the main Java class file.

I just had a few minutes and disassembled the class files contained in the jar file. What i find interessting is that i didn't find anything which is related to executed the hidden exe file. Maybe the exefile is not executed at all, but if it is there must be a very interesting way.

The only think I saw was, that the class try to load something from a properties file, which is missing.

I don't have an environment where i can execute the virus to see whether the exe file is executed or not.

Maybe some of you guys have a system to play with.
