Winifighter Clone: TrustFighter

RogueAntiSpyware.Winifighter_TrustFighter6

Another scareware has been spotted in the wild and it calls itself TrustFighter. This is a recent addition to the Winifighter family of scareware.

Same as other members of this family of scareware, as in a previous post, TrustFighter creates heaps of junk binary files in the %systemroot% and %system% directories.

Sample junk files are the following:

%systemroot%\51c0vzr24975.dll
%systemroot%\51cbthreatz1991.ocx
%systemroot%\524699py69fz.bin
%systemroot%\525z1vi9us4e4.cpl

Bogus MS Update

We have been receiving bogus emails claiming to be coming from Microsoft:

...public distribution of this Update through the official website »www.microsoft.com would have result in efficient creation of a malicious software, we made a decision to issue an experimental private version of an update for all users Microsoft Windows OS.
as the computer set to receive notifications when new updates are available, which you have received this notice.

We have seen emails containing one of the following links:
hxxp://www2.sinel.com/microsoftupdate.html
hxxp://mail1.e-corecorporation.com/default.htm


They seem to be compromized websites being used by the bad guys in order to facilitate this attack.

The page default.html from hxxp://mail1.e-corecorporation.com/default.htm uses a refresh-type redirect to this url:
hxxp://0xc0.0xdc.0x6e.0xe4/microsoftupdate.html

The page microsoftupdate.html from sinel.com and 0xc0.0xdc.0x6e.0xe4 both execute another refresh-type redirect in order to download a Zeus malware with filename update09.exe.

Interestingly enough, this attack uses 0xc0.0xdc.0x6e.0xe4 to serve the malware. This IP-address translates to 192.220.110.228, which in turn resolves to summit102.summitdesign.net, another possibly compromised website used in this attack.

The presence of the following files/folders may indicate signs of infection:
%System%\sdra64.exe
%Temp%\tmp.exe
%System%\lowsec\

Another Shameless SEO based on Atlanta Flooding

Users Googling "Atlanta flood pictures" receive a yet another SEO attack, using a possibly compromised legitimate Australian website hosting restaurants in the famous Bondi area.

Here's a screenshot of a google search result:
atlanta_flood_google

A Fiddler capture shows us the redirections:
atlanta_fiddle

So we go from
hxxp://idrb.com/pdf_files/atlanta-flood-pictures.html
>hxxp://06d.ru/t.php
>>hxxp://read-cnn2.com/?pid=207&sid=de9f8f
>>>hxxp://winfixscanner7.com/scan1/?pid=207&engine=pHTyzjTyMzEyOS44Mi4xOTAmdGltZT0xMjUuNgAMPAVN


An installer named Soft_207.exe will be presented for download, which is a variant of the Total Security family of Fake AVs.

At the moment, the following domains have been observed to have been involved in this attack:

winfixscanner7(dot)com
15scanner(dot)com


These domains resolve to the following IP addresses:
89.47.237.55
89.248.174.61
213.163.89.60


But knowing the trend in scareware, there could be heaps more domains being created as we speak.

Koobface on the Move, Serving Scareware !!

We have been seeing a lot of new movement on the koobface front Lately.

koob_fiddle

As koobface-serving domains are being taken down as early as the good guys discover them, the bad guys are at it and they respond by registering new ones. At the moment, their, C&C server is hosted in China with IP Address 61.235.117.83.

The bad guys are still using a fake facebook website, as well as posing as a fake codec, in order to distribute koobface.

fake_facebook

Clicking anywhere on the page, presents us with a file named setup.exe. Here are some of the IPs being used to distribute koobface:

koob_script

115.130.27.204
123.202.200.84
151.204.31.67
196.206.65.53
221.126.0.105
24.215.207.229
41.238.76.198
61.93.34.23
67.206.253.52
68.47.48.240
69.18.107.115

98.26.40.38
99.22.74.229


The javascript component being by used by koobface, remains bascically the same as before

And as before, koobface is still serving up scareware. From time to time, users are presented with a My Computer online scan, going through these domains:

rogue

gotrioscan(dot)com
plazec(dot)info


At some instances, we also get these warnings:

hardware_error
Internet_Antivirus_Pro

At the moment, these warnings are serving Internet Antivirus Pro.

Update:
Koobface has been going at it and here's another one that spoofs youtube and serves koobface malware as a fake codec:

hxxp://71.197.170.226/d=www.marcellaburnard.com/0x3E8/view/console=yes/?go

Porn site distributes scareware

Another website has recently been spotted to be serving up malware in the guise of fake video codecs.

This one praises itself as "The Best Nude Celebrity Movie Site"
hxxp://alyssafan.net/1.html

face_codec

But in order to watch the any video, we would need to download and install their "Certified ActiveX video codec (VAC codec) use to protect content Copyrights"

The fake fake codec can be downloaded here:
hxxp://alyssafan.net/Mediacodec_v4.8.exe

One of the components used in this attack is an onfuscated javascript file that can be found in the %temp% folder.

obfuscated

This script translates to:

deobfuscated

This script downloads:
hxxp://ue4x08f5myqdl.cn/u3.exe

Which then gives us scareware Safety Center:

safetycenter

Beware of fake video codecs!
