Troj/Ataka-E is a multicomponent IRC backdoor Trojan.
The main installer component (sx.exe) is typically downloded from the internet by a downloader. The installer drops the following files:
calc32.exe
gamma.exe
ght.dll
hajr.drv
infsyst.reg
kasperlamm.cab
msvcrtd.dll
nocx.ocx
NoeWinnt.exe
oje.txt
syn32.exe
into the folder Program Files\NetMeeting\conf\.
Some of these files are clean and are not detected. Gamma.exe is a Trojan dropper and is detected as Troj/Prx-A.
Troj/Ataka-E sets the following registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
NTsocket = C:\Program Files\NetMeeting\conf\NoeWinnt.exe
