Email with subject “scan upon download” contains trojan

MX Lab started to intercept a few emails with the subject “scan upon download” coming from randomly spoofed email addresses.

The trojan is named Suspicious:W32/Malware!Gemini (F-Secure) or Mal/TibsPk-D (Sophos) and is able to create malicious executable files on the infected system.

The body of the email:

Dear Sirs,
We have prepared a contract and added the paragraphs that you wanted to see in it. Our lawyers made alterations on the last page. If you agree with all the provisions we are ready to make the payment on Friday for the first consignment. We are enclosing the file with the prepared contract.

The email has the ZIP archive attached named Contract.zip, a 202 kB large file, and once extracted an executable file named Contract.exe appears.

The following files are created:

%AppData%\av.exe
%AppData%\v7LsGuo3u6bku

A new process is created:

Directory scam: Registration of the World Business Directory 2010/2011

MX Lab reported in 2009 about the misleading marketing trick that the World Business Directory uses. Guess what, they are back!

MX Lab received a new registration form from the World Business Directory and again, we want to point out a few things before you sign their contract.

The email comes from info@companyworld2010.com, with the subject “Registration of the World Business Directory 2010/2011″ and this is the email content:

Dear Madam/Sir,

In order to have your company registered in the World Business
Directory for 2010/2011, please print, complete and return the
enclosed form (PDF file) to the following address:

World Business Directory
Suite 149 – Rosden House – 372 Old Street
EC1V 9AU / London – United Kingdom
E-mail: office@companyworld2010.com
Fax: +44 207 806 8157

Updating is free of charge!

To unsubscribe, please send an email to
unsubscribe@companyworld2010.com

Attached is a PDF file named world-businessdirectory.pdf.

The 1st point that needs your attention is the text block 1:

To update your company profile, please print, complete and return
this form (Updating is free of charge). Only sign if you want to
place an insertion.

As you can read, updating is free of charge but if you want your company get listed in this directory you will need to sign and have to pay.

What is the price of this directory you may ask yourself? Well, you have to go to text block 2 with the very small letters and this includes:

I WILL HAVE AN INSERTION INTO ITS DATA BASE FOR THREE YEARS. THE PRICE PER YEAR IS GBP 980.

And there you have it, this contract will cost your business a total amount of GBP 2940 over 3 years. After the 3 years subscription you can stop your contract if you inform them on time:

THE SUBSCRIPTION WILL BE AUTOMATICALLY EXTENDED EVERY YEAR FOR ANOTHER YEAR, UNLESS SPECIFIC WRITTEN NOTICE IS RECEIVED BY THE SERVICE PROVIDER OR THE SUBSCRIBER TWO MONTHS BEFORE THE EXPIRATION OF THE SUBSCRIPTION.

A few arguments from our side that this is a scam:

The from email address contains the domain companyworld2010.com and when trying to see if there is a site online we got the notification “This account has been suspended”. We might see new emails from the World Business Directory appear with other domains.

When getting some WHOIS information on the domain we got the following:

Registrant:
 international group c/o Free Private Reg
 P.O. Box 81024
 Burnaby, BC V5H 4K2

    DNS7.DOTEASY.COM   65.61.198.14

 Domain status: clientTransferProhibited
                clientUpdateProhibited

The registrant information is rather vague and points to a PO Box and the administrative contact has the same address. The domain freeprivateregistration.com in the email address of the administrative contact is just a domain alias from doteasy.com. These details must be fake.

In 2009, the PDF document needed to be returned to an address in The Netherlands, in this 2010/2011 edition it needs to be returned to an address in London, UK.

When visiting their site at http://www.world-businessdirectory.com/ on the ‘About us’ page we found the following text:

The World Business Directory online is product of EU Business Services Ltd, a corporation organized and existing under the laws of Nevis, West Indies.

We also  found the UK address on the ‘Contact us’ page.

Our recommendation is: don’t sign the document and don’t do business with this company.

Follow these guidelines if  you are a victim of this directory scam:

  • Do not pay, even if they imply to take your case to court.
  • If you have paid a certain amount, stop the next payments. Expect that you won’t get a refund either.
  • Send them a letter informing them you have been misled and telling them to cancel the contract.
  • If possible, report to (local) authorities.

Web site creator hosts are being abused in spam campaigns

Spammers are not afraid to abuse community sites or blog creators like blogspot.com in their spam campaigns. In some cases, the content is published on these site or a redirect is embedded and forwards the visitor to the web site of their choice offering porn, pills and other stuff.

MX Lab noticed an increase the last few days of URLs in spam messages that point to (free) web site creater hosts or less well know blog creators. Some of the latest victims are doodlekit.com, sitekreator.com, webs.com, webstarts.com and blogdrive.com.

Some examples of the spam:

of necromancer beyond power drill ostensibly wily
dissidents customer
PornstarMikaTanAnalFingering hxxp://trhombic.blogdrive.com
because girls

dissidents blotched greedily

mirror about starlet likeable

over and accidentally

tea parties flabby
WorldOfLustyAmatenurGalsFujckkingOnCameraWithBigCobckedLadsAndBelovedSjexToys hxxp://s2.webstarts.com/ssey/q2.html

philosopherssecretly

What we also notice is the use of random words in the spam message again. This is a very common technique being used in the past to avoid detected by Bayesian filters and/or to compromise and corrupt the knowledge database of the Bayesian filter when the message is used to train the filter.

This technique is also present in the latest spam campaign of the Canadian Pharmacy:

This is a link to our shop http://bc.greatsilent.ru/

ajitikumoa fiaxe oqoce qiahow yvenouwa bosyebuje ucotaley
yeqa uhybyo nidodyziru logu noboma uuju uedywaby
…. (cut)….

New web site creator hosts are being used each day. When I visited a few of those web site creator host I found out that subscription is so easy to do. You can automate account requests quite easily up to a certain point without being blocked by some way of security measure or by clicking on an activation link by email.

On doodlekit.com we found a CAPTCHA security on the subscription web form but I believe that a good CAPTCHA should have letters that are less readable than this one. But, this is a start.

On webs.com I did set up a dummy web site account with the site address http://tryviagra.webs.com without any security measure! This means that anyone can set up an free web site creator account when completing the webforms.

In this particular case, I can even automate every step and let a bot do all the work for you. I could create from 10 to 100 accounts on a day and perhaps the site administrators wouldn’t even notice this. It is a very efficient way of getting coverage on the internet, getting free hosting for my site or redirect visitors to my site.

To make it worse, I can also place malware on this site and try to infect each visitor on my site with malware, ransomware or other malicious files.

As a spammer, I have the advantage over Intent Anyalisis tools or SURBL, tools that examine and block messages based on the included URLs, by generating mutliple URLs each day and changing URLs in the spam message.

Again, it shows that internet security is a responsability of everyone and everyone should get involved. If we want to stop spammers, we also have to make sure that some of the features that spammers have today – this is a nice example I think – can’t be used tomorrow.

Feel free to comment on this post.

Disclaimer: it is not our intention to attack webs.com on their lack of security – perhaps in a certain way it is – but to point out how easy it is to abuse certain online tools.

Email regarding Conflicker.B Infection Alert contains a trojan

MX Lab started to intercept emails with the subject “Conflicker.B Infection Alert”. The trojan is names Win32:Bredolab-CC (Avast), Generic Dropper.lr (McAfee) or Trojan.Win32.Bredolab.Gen.2 (Sunbelt).

The from address is spoofed and can contain “Microsoft Team”. The emails is signed by “Microsoft Windows Computer Safety Division” to make it appears that it is from Microsoft itself.

The email has the attachment open.zip and inside the ZIP archive the executable open.exe (16 kB).

As you can read, the email contains instructions to use the attached file to scan your network after an detected virus infection by the Conflicker worm.

Dear Microsoft Customer,

Starting 12/11/2009 the ‘Conficker’ worm began infecting Microsoft customers unusually rapidly. Microsoft has been advised by your Internet provider that your network is infected.

To counteract further spread we advise removing the infection using an antispyware program. We are supplying all effected Windows Users with a free system scan in order to clean any files infected by the virus.

Please install attached file to start the scan. The process takes under a minute and will prevent your files from being compromised. We appreciate your prompt cooperation.

Regards,
Microsoft Windows Agent #2 (Hollis)
Microsoft Windows Computer Safety Division

At the time of writing, 21 of the 40 AV engines at Virus Total did detect the threat correctly. Our recommendation is that you never following instructions, send by email, like this one. Microsoft, or any other company, will spread security tools by email.

This trojan is a serious security risk because it will display fake alerts regarding a virus infection in order to lead you to buy rogue anti virus/anti spyware products. The trojan also has the capabilities to send out emails with a build-in SMTP engine.

A new windows will be created after executing the file open.exe:

The following files are created:

%CommonAppData%\28701826\28701826.exe
%DesktopDir%\Security Tool.lnk
%Programs%\Security Tool.lnk

The following directory is created:

%CommonAppData%\28701826

New processes are created:

28701826.exe in C:\DOCUME~1\ALLUSE~1\APPLIC~1\28701826\28701826.exe

The Windows registry will be modified and the malware can open the TCP ports 1066 and 1067 ports on an infected system.

“updated account agreement” email contains Bredolab trojan

MX Lab started to intercept emails with the subject “updated account agreement” that contains the Bredolab trojan. The campaign is designed for Facebook users because of the content. The email comes from the spoofed email address and contains “Facebook Team”.

The body of the email:

Dear Facebook user,

Due to Facebook policy changes, all Facebook users must submit a new, updated account agreement, regardless of their original account start date.

Accounts that do not submit the updated account agreement by the deadline will have restricted.

Please unzip the attached file and run “agreement.exe” by double-clicking it.

Thanks,
The Facebook Team

The email has the ZIP archive agreement.zip attached, once unpacked the file 28 kB big file agreement.exe is available.

Facebook, or any other company, will never distribute agreements,  software updates and patches or anything else in emails. Our recommendation is to delete the email immediatly because a lot of AV engines do not detect this variant very well at the moment.
