freac.net is back with a BBB spam run

freac.net is a domain used by malicious spam email pretending to be from the BBB or NACHA, as in this example. In that case, freac.net was apparently hosted on an IP belonging to Huawei in the US, but shortly afterwards it went non-resolving.

Well, freac.net is back and so is the spam promoting it.. e.g.

Currenly freac.net is hosted on 46.4.226.18 and 41.64.21.71, the first is a server rented from Hetzner in Germany, oddly the second is an ADSL line in Cairo.

Anyway, blocking those IPs will stop any further infections from those IPs. A Wepawet report for this infection is here.

Something evil on 212.95.54.22 (inferno.name)

Something evil is lurking on 212.95.54.22, a server belonging to black hat host inferno.name (mentioned here before).

I've never seen a legitimate site hosted by inferno.name, and I recommend that you block their IP ranges.. I ideidentified the following list last August, I haven't had the change to go back and check it again.

212.95.63.0/24

These are the some of malicious sites hosted on that server, it appears to be some sort of injection attack although it is still being analysed.

"Submit your tax refund request" malware / synergyledlighting.net

This spam leads to a malicious payload on synergyledlighting.net - a domain we have seen a lot of recently with a habit of moving around.

Date:      Wed, 14 Feb 2012 18:06:23 +0530
From:      "Rolland Quintana"
Subject:      Submit your tax refund request
Attachments:     irs_logo.jpg

After the last annual computations of your financial activity we have determined that you are eligible to get a tax refund of $802.

Please submit the tax refund request and allow us 3-9 days in order to process it.

The delay of a refund can be caused by a variety of reasons.

E.g., sending incorrect records or not meeting a deadline.

To learn the details of your tax refund please open this link.

Best regards,
Tax Refund Department
Internal Revenue Service

The malware starts at synergyledlighting.net/main.php?page=6d63cba62f5eb9a0 and then downloads various components (report here). Today synergyledlighting.net is on 178.211.40.29 (Sayfa Net, Turkey). This is one where blocking both the IP and domain is probably a good idea.

SOCA seize rnbxclusive.com. Due process, anyone?

I've never heard of RnBXclusive (rnbxclusive.com), but it is a site to do with Urban Music which isn't really my cup of tea. However, visitors to the site today get a message from SOCA saying:

SOCA has taken control of this domain name.    
The individuals behind this website have been arrested for fraud.

The majority of music files that were available via this site were stolen from the artists.    
If you have downloaded music using this website you may have committed a criminal offence which carries a maximum penalty of up to 10 years imprisonment and an unlimited fine under UK law.      
     
Your IP     Your Browser     Your OS     Time / Date
193.110.241.235
    Firefox10.0.1     WinXP     06:46:37

    The above information can be used to identify you and your location.

SOCA has the capability to monitor and investigate you, and can inform your internet service provider of these infringements.

You may be liable for prosecution and the fact that you have received this message does not preclude you from prosecution.

As a result of illegal downloads young, emerging artists may have had their careers damaged. If you have illegally downloaded music you will have damaged the future of the music industry.

Visit pro-music.org for a list of legal music sites on the web.

One annoyance is that SOCA display the IP address of the visitor and basically accuse the visitor of being a criminal. But, more seriously, SOCA's message indicates that the site operator was guilty of illegal activities without a trial. Remember courts? Judges? That sort of thing? Any good lawyer could probably argue that SOCA's statement is prejudicial.

Also of interest, the .com name is registered through GoDaddy in the US, the site is hosted on 83.138.166.114 which appears to be in a Rackspace facility in the UK. It looks like SOCA might have gained control of the server rather than the domain name which shows no WHOIS changes.

TorrentFreak have some additional information here.

I can't believe that there is a person in the world receiving this who will not have received hundreds of versions of the same thing before, but the spammers continue. The malicious payload is at biggestloop.com/main.php?page=27f6207e33edeeca (analysis here) on 206.214.68.57 (B2Net Solutions, Canada). Block the IP if you can. Better still, write some filters for your email system to keep the things far, far away.

This why I won't be using F-Secure Mobile Security

F-Secure Mobile Security is not a bad product - it includes anti-theft software, a virus scanner and a supposedly secure browser. In the UK, F-Secure charge £29.95 a year for this, which is pricey for an Android application, but usually F-Secure products are very good. You can get a month's free trial before you buy.

It has some strengths and weaknesses. But I won't upgrading to the paid version. Why not? Well, every day the same nag message comes up:
F-Secure would like to have your phone number for the purposes of possible product information and marketing related messaging. The cost of approval is that of one-stime standard SMS to Finland. Do you agree?
There are two buttons.. Yes and No. Click "No" and the message seems to go away.. until the next day. And the day after that. And the day after that. You get the picture. Either this is a bug or it is a very aggressive attempt to get you to agree to SMS marketing. Either way it's a big turnoff and I'll be looking for another product to protect my Android..

The malware is on freac.net/main.php?page=cd12dfacc57c3f82 (report here) which is on IP address 12.133.182.133 (Huawei Technologies, US). Blocking access to the IP address will prevent any other malicious sites on the server from being a problem.

Good day

Attached the intercompany inv. for the period Dec. 2011 til Jan.. 2012.

Thanks a lot for supporting this process

The obfuscated javascript in the attachment attempts to download malicious code from coajsfooioas.ru:8080/images/aublbzdni.php followed by more code from tuberkulesneporok.ru:8080/images/jw.php?i=8 (Wepawet report here).

These domains are multihosted on the same IPs as listed here. Blocking access to those IPs should stop further malware attacks from being successful.

The malware is at cooldcloud.com/search.php?page=73a07bcb51f4be71 hosted on 74.91.117.227 (Nuclear Fallout Enterprises... again). Blocking the IP is best as that will protect against other malware, although you may want to block more widely given the problems with this host.

The malware tries to download additional content from twistcosm.com/forum/index.php?showtopic=656974 on 199.30.89.139 (Central Host / Zerigo Inc), another problem hosting company.

This is a system generated email. Please do not respond.

The malicious payload is synergyledlighting.net/main.php?page=4e4959105994cf84  hosted on 131.94.130.132 (Florida International University, US) and 173.236.78.113 (Singlehop, US). That same domain was found in this spam, although one of the IPs has changed since then.

The Florida International University IP address gives a clue as to what is going on here - these servers are most likely hacked rather than rented. This also explains why some IPs have seemingly legitimate sites on them. Still, blocking access to these IPs is the safest thing to do.

"Invoice_8W20576.htm" is an HTML attachment containing some obfuscated Javascript that connects to kamarovoskorlovo.ru:8080/images/aublbzdni.php which then attempts to download some malicious components from that domain and also serebrokakzoloto.ru:8080/images/jw.php?i=8 .

Evil network revisited (again): Specialist Ltd / Specialist-ISP-PI2 AS48691(194.28.112.0/22)

Specialist ISP is a black hat hosting company in Transnistria that I have covered before. Things have been a bit quiet on that front for a while until today when the malware site enswdzq112aazz.com came to my attention.

"Acid Free Coffee" spam.. again.

Another spam run promoting "acid free coffee", but this time the spammers are trying a trick to avoid detection.

From:      "Acid Free Coffee" [ppingu84@yahoo.com]
Subject:      Acid Free Coffee

I just discovered this amazing coffee. Its incredibly smooth and rich like nothing I have ever tasted before. Google Acid Free Coffee or click here http://tinyurl.com/6otas83 to search it. This is really worth your time.

The link really does go to Google, specifically https://www.google.com/search?sourceid=chrome&ie=UTF-8&q=acid+free+coffee .. and who is the first result for acid free coffee? It's Tylers Coffees who have been seen before in this spam run.

Tylers Coffees deny having anything to do with it.. or at least someone claiming to be Tylers Coffees denied it in the comments to the previous post: "we are sorry about all this. We have our IT looking in to it. IT WAS NOT SENT BY US. Thank you for your support please email us for a free bag of coffee we again a very sorry for the incovinces"

This time the spam came from 173.192.141.86, an IP address belonging to Softlayer Technologies in the US, but suballocated to an Indian outfit called ucvhost.com.


According to Tylers Coffees Facebook page, other people are seeing exactly the same thing:


My personal opinion is that "acid free coffee" sounds like some sort of beverage made from snake oil, but if people want to buy it then that is fair enough.. however, if Tylers Coffees really are promoting a brand through spam then is both unethical and illegal.
