A few days ago 2245 *.JPEG Files appeared on my computer. The total volume
equated to 180MB. The files were pornographic in nature. They appeared to
'unzip' near midnight, when the computer was turned on - but I wasn't logged
onto it - and I was not connected to the internet. When a work colleauge of
mine was using my machine, she clicked on a couple of files eg/ woman2.png.
These files opened folders i.e. Temporary Directory 1
ix_fs_all.zip/24x24/shadow. Neither the folders nor the *.png files were
able to be seen in the directory listing. AND the 2245 *.JPEG files were
visible in the directory listing, but were not visible in the windows
explorer environment - unless the 'Hide protected operating system files'
options was not selected. Further, she clicked on one file twice and it
created two lots of Temporary Directories as opposed to re-using the one it
had already created.

The 2245 JPEG files were discovered by my IT department who apprehended me
because they believed that I placed the files on the PC. OK - so I know that
I did not do it. But, IT are saying that it couldn't be malware because if
180MB of files (? when zipped) came through the firewall, they would have
either picked it up on the firewall or been able to find it when they scanned
the system - neither of which happened.

They are now saying that I had a PDA connected to the computer at the time
when the files arrived onto it - and therefore, when the PDA failed it
dropped 180MB of files onto my computer.

I am at a bit of a loss and also 'a lot in trouble'. Keeping pornographic
materials on your PC is a summary dismissal event here.

Does anyone have any idea of what could have happened?

The event logs at the time the file arrived onto the computer were (Date is
24/02 unless otherwise specified):

Yes, Malware is at is the root. Maybe not a virus but definitely malware.



If you are using any version of Sun Java that is prior to JRE Version 6.0,
then you are strongly urged to remove any/all versions.
There are numerous vulnerabilities in them and they are actively being exploited.

It is highly suggested that you update to the latest version which is Sun Java
JRE/JSE
Version 6.0

Simple check, look under...
C:\Program Files\Java

The only folder under that folder should be the latest version.

Such as...
C:\Program Files\Java\jre1.6.0

http://java.sun.com/javase/downloads/index.jsp
http://www.java.com/en/download/manual.jsp

For non-viral malware...

Please download, install and update the following software...

* Ad-aware SE v1.06
http://www.lavasoft.de/
http://www.lavasoftusa.com/
http://www.lavasoft.de/ms/index.htm

* SpyBot Search and Destroy v1.4
http://security.kolla.de/
http://www.safer-networking.org/microsoft.en.html

* SuperAntiSpyware
http://www.superantispyware.com/superantispywarefreevspro.html

After the software is updated, I suggest scanning the system in Safe Mode.

I also suggest downloading, installing and updating BHODemon for any Browser
Helper Objects
that may be on the PC.

* BHODemon

http://www.majorgeeks.com/downloadget.php?id=3550&file=11&evp=245a87539eea8ed6904332b4b8b8442d

For viral malware...

* Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go
through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal
Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the
PC.

You can choose to go to each menu item and just download the needed files or you
can
download the files and perform a scan in Normal Mode. Once you have downloaded
the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode
[F8 key
during boot] and re-run the menu again and choose which scanner you want to run
in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive
PDF help
file. http://www.ik-cs.com/multi-av.htm

Additional Instructions:

* * * Please report back your results * * *

Hi David,

Our IT Deparment says that it is not possible for zip files (unzipped at
180MB) of data to have come through the firewall without being detected.
AND, it is also not possible that this large volume of files could have sat
on the C:\ without being picked up.

Not sure how they are scanning - but if they are scanning for a volume
retrospectively, how could they be sure?

I'd really appreciate your comments.

Helen

You mentioned an enormous amoust of porn JPEGs and unless it was done
deliberately by a
person at the PC it was done by malware.

I don't what the IT group monitors but I can see a ZIP file get through.
