Injection attack: malavasso.com, migraviro.com and montenegrorio.com

Three more domains being used in injection attacks today:

malavasso.com
migraviro.com
montenegrorio.com

The payload is the Sinowal trojan. Malicious software is hosted on 95.64.45.43 which is well-known very dark grey hat host Netserv Consult SRL of Romania. Blocking 95.64.0.0/17 (95.64.0.0 - 95.64.127.255) will probably do no harm.

The (possibly fake) registrant for these domains is:
Registrant Contact:
   Xicheng Co.

bundespol.com is not the Bundespolizei

Another fake Bundespolizei today, bundespol.com is registered through  a Chinese registrar and then is anonymised through a Chinese WHOIS privacy service

The site doesn't resolve yet, but it is almost identical to bundespol.net which is fingered in this attack. In that case, the fake Bundespolizei site was hosted on 188.229.97.2 which is Netserv Consult SRL in Romania (incidentally, blocking 188.229.0.0/17 will probably do you no harm).

There's a whole bunch of fake Bundespolizei at the moment, but I'm guessing that this particular bunch of scammers may well try the same thing in other countries very soon.

Fake banks on 88.191.36.45

88.191.36.45 [Proxad, France] is hosting a series of fake banking domains, one of which is detailed by F-Secure.The domains target Finnish and Spanish banks.

The following sites appear to be hosted on that IP:

bbva-es.com
nordea-vf.com
nordeasfi.com
nordea-if.com
nordea-fis.com
osuuspankki-fi.com


Some sites might use the following subdomains: kultaraha, solo1, solo2, www and xxx.

The (fake) registrant details are:
  Admin Name........... Arthur Williams
  Admin Address........ lake tarson 41
  Admin Address........
  Admin Address........ new york city
  Admin Address........ 90121
  Admin Address........ NY
  Admin Address........ UNITED STATES
  Admin Email.......... sir.arthur999@hotmail.com
  Admin Phone.......... +1.802716100

Blocking access to 88.191.36.45 would probably be a good idea if you have Spanish or Finnish users.

Injection attack: cbchhuacyus.com, ibccmsuiyus.com and wbccmquwyus.com

There is currently a Sinowal injection attack doing the rounds, redirecting traffic to the following domains on 46.165.192.97:

cbchhuacyus.com
ibccmsuiyus.com
wbccmquwyus.com

There may well be other domains on the same server, blocking traffic to 46.165.192.97 would probably be prudent. The payload is being analysed (I will post an update later), but detection rates are not good.

Fake "internationalservicecheck.com" email

The email originates from a server at 70.32.113.152 which belongs to Fivecube Pte in Singapore (the server is physically in California), although most likely this is either a compromised server or a customer. An examination of the mail headers indicate that it may originate from 69.92.92.47, a Cable One subscriber in Seminole, Oklahoma. The Reply-To address is adele.green@aol.com althought this is probably fake, so do not assume that it really is someone of that name behind it.

bundespolizei-online.com is not the Bundespolizei

bundespolizei-online.com is a fake domain pretending to be the Bundespolizei (German Federal Police). It appears to be part of a malware scam that has been around for a while, where the victim is told that they have done something illegal and need to pay a fine to the police.

The text of the message might vary, but the last scam domain  was used in conjunction with a message that read:

Es ist ungesetzliche Tätigkeit enthüllt
Achtung!!!
Ein Vorgang illegaler Aktivitäten wurde erkannt.
Das Betriebssystem wurde im Zusammenhang mit Verstoßen gegen die Gesetze der Bundesrepublik Deutschland gesperrt! Es wurde folgender Verstoß festgestelltt: Ihre IP Adresse lautet "x.x.x.x" mit dieser IP wurden Seiten mit pornografischen Inhalten,Kinderpornographie, Sodomie und Gewalt gegen Kinder aufgerufen Auf Ihrem Computer wurden ebenfalls Videodateien mit pornografischen Inhalten, Elementen von Gewalt und Kinderpornografie festgestellt! Es wurden auch Emails in Form von Spam, mit terroristischen Hintergründen, verschickt. Diese Sperre des Computers dient dazu, Ihre illegalen Aktivitäten zu unterbinden.
Ihre IP: x.x.x.x
Location: XXXXX
ISP: XXXXX
Um die Sperre des Computers aufzuheben, sind Sie dazu verflichtet eine Strafe von 100 Euro zu zahlen. Sie haben zwei Möglichkeiten die Zahlung von 100 Euro zu leisten.

    1) Die Zahlung per Ukash begleichen:
    Dazu geben Sie bitte den erworbenen Code in das Zahlungsfeld ein und drücken Sie anschliessend auf OK (haben Sie mehrere Codes,so geben Sie Diese einfach nacheinander ein und drücken Sie anschliessend auf OK) Sollte das System Fehler melden,so müssen Sie den Code per Email (einzahlung@dpolg-bundespolizei.org) versenden.
    2) Die Zahlung per Paysafecard begleichen:
    Dazu geben Sie bitte den erworbenen Code (gegebenfalls inkl. Passwort) in das Zahlungsfeld ein und drücken Sie anschliessend auf OK (haben Sie mehrere Codes,so geben Sie Diese einfach nacheinander ein und drücken Sie anschliessend auf OK) Sollte das System Fehler melden,so müssen Sie den Code per Email(einzahlung@dpolg-bundespolizei.org) versenden.
This roughly translates as:

It is illegal activity revealed
Attention!
An operation of illegal activity has been detected.
The operating system was blocked in connection with Violating the laws of the Federal Republic of Germany! It was festgestelltt following violation: Your IP address is "xxxx" with the IP were pages containing pornography, child pornography, bestiality and violence invoked against children on the computer were also video files containing pornography, found elements of violence and child pornography! There were also emails sent in the form of spam, with terrorist backgrounds. This serves to lock the computer to stop your illegal activities.
Your IP: x.x.x.x
Location: XXXXX
ISP: XXXXX
To unlock the computer, you have to pay a penalty verflichtet of 100 €. You have two ways to make the payment of 100 €.

     1 pay) Payment via Ukash:
     You enter the acquired code into the payment box and then press OK (you have multiple codes, enter this simply a sequence, then press OK) If the system is wrong, you have the code by email (einzahlung@dpolg-bundespolizei.org) ship.
     2) The payment by paysafecard to pay:
     You enter the acquired code (if necessary including password) into the payment box and then press OK (you have multiple codes, enter this simply a sequence, then press OK) If the system is wrong, so you must send the code by email (einzahlung@dpolg-bundespolizei.org).

A €100 fine for terrorist likes and download child pornography? Obviously this is nonsense, but the victim might well try to pay to get rid of the trojan.

The bundespolizei-online.com is quite interesting to look at. First, there is the WHOIS record:

    Steffen Schüssler
    Email: t-mart-admin@teiekom.de
    Organization: Hostmaster T-Systems
    Address: Vahrenwalder Strasse 240-247
    City: Hannover
    State: Hannover
    ZIP: 30159
    Country: DE
    Phone: +49.43171633486
    Fax: +49.43171633486

It looks legitimate enough. T-Systems is the hosting division of Deutsche Telekom, and the email address looks legitimate at first glance.. but wait, it says teiekom.de and not telekom.de which can't be right.

The domain is registered through the Russian registrar Regtime Ltd. The site bundespolizei-online.com is hosted on 193.105.240.204 in Latvia. Latvia is pretty much a hotbed of crime, and the AS12578 block has a pretty bad reputation, and the whole 193.105.240.0/24 range looks quite toxic. As is common with malicious sites such as this, all the mail is handled by Google.

So.. if you see a message soliciting an email reply to bundespolizei-online.com or running on the same website then it is malware, and you should try to disinfect your machine using up-to-date antivirus software, or you could try following the instructions here.

Why am I sending myself spam?

One of the most comment questions I get about spam is: "Why am I sending myself spam?" The most common answer to this is: "It's a forgery, you are are not sending yourself spam at all".

This answer requires some explanation, but the most important thing is that when you see spam both "To" and "From" you at the same time then it DOES NOT mean that someone has hacked into your email account. However, if a friend or contact is getting spam email "From" you  then it is quite possible that someone HAS hacked your email account and you should take appropriate action.

These mail forgeries are incredibly simple to do. Part of the problem is that the protocols that email runs on were written in the early 1980s when there was no such thing as email spam. Basically, when one computer connects to another computer to send mail then usually the receiving computer trusts that the sending computer is telling the truth about the sender.

The conversation between the two computers looks something like this:

HELO
MAIL FROM: sender@sender.domain
RCPT TO: recipient@recipient.domain
DATA
This is the body text of the email.
.
QUIT

What might come as a shock is that the sender's email address specified in "MAIL FROM" can be anything at all, including being the same as recipient. This is technically known as spoofing (i.e. it is a form of forgery), and it explains as well why spam often seems to come from nonsense email addresses. There are some ways of stopping spoofing, such as SPF, but they are not very widely used.

One reason why spammers like to send spam "from" the victim is because it will often get through the victim's spam filters. In general, you should not whitelist your own email address in your spam filter for this reason. Fixing spoofing at a filter level is possible, but every email system and spam filter is different and this is really one for experienced IT support people to resolve for you.

I mentioned earlier about a different scenario - one where the mail appears to be "From" a contact. Although superficially it might appear to be similar, in this case it usually means that an email account has been hacked into, typically the person that the mail is "from". If you receive spam from someone you know then the best thing to do is contact them offline and let them know that there's a problem.

9/11 reflections

You've probably noticed that the tenth anniversary of the September 11th attacks is coming around in a few days time. There's a lot a material around covering all sorts of aspects, but one of the things that I distinctly remember (as a distant observer) was that there were a lot of important things happening, but it was hard to find out what was happening because the 2001-era web couldn't cope with the thirst for information. I wrote about it few days afterwards because it was probably the first time that the web had to deal with such a monumental news story.

In some respects the situation is very different ten years on. News sites are much more resilient, Twitter gives us real-time updates of major events, YouTube can give us raw eyewitness footage just minutes after things have happened. But the recent attacks in Oslo demonstrate just how fragile technology can still be.

Anyway, you can read my thoughts a decade on here if you like.

Fake jobs: allworld-career.com, greece-newcareer.com, new-joboffers.com and worldjob-career.com

Four new domains offering a variety of fake and illegal jobs, part of a very long running series of scam emails.

allworld-career.com
greece-newcareer.com
new-joboffers.com
worldjob-career.com


These fake domains have been set up to solicit replies to bogus job offers, including money laundering and other illegal activities. The emails may appear to have been sent from your own account, but this is a simple forgery and does not mean that your email account has been compromised.

The registrant details are no doubt fake:

    Alexey Kernel
    Email: johnkernel26@yahoo.co.uk
    Organization: Alexey Kernel
    Address: Kreshchatyk Street 34
    City: Kiev
    State: Kiev
    ZIP: 01090
    Country: UA
    Phone: +38.00442794512 

All these domains have been registered in the past couple of days.

If you have a sample spam with one of these in, please consider sharing it in the Comments. Thanks!

Saturday, 3 September 2011

Fake jobs: usa-newcareers.com

usa-newcareers.com is another domain being used for offer fake jobs (usually criminal activities such as money laundering). Is is part of this long running scam and is essentially just a variant of us-newcareer.com registered a few days ago. The domain was registered yesterday to a presumably fake registrant.

One feature of these scam emails is that they appear to come from yourself, this is just a simple forgery and it does not mean that your mail account has been compromised. If you have any examples of spam using this domain, please consider sharing it in the comments.

dpolg-bundespolizei.org is not DPolG or the Bundespolizei

DPolG is a staff a association of the German Federal Police (Bundespolizei). So you might expect that dpolg-bundespolizei.org is something to do with the DPolG.. especially when the www.dpolg-bundespolizei.org resolves to 77.87.229.14, which is the same IP address as bundespolizei.de which is the German Federal Police.

But something is very wrong with this domain.Let's start with the WHOIS details:

Domain ID:D163178250-LROR
Domain Name:DPOLG-BUNDESPOLIZEI.ORG
Created On:30-Aug-2011 11:02:35 UTC
Last Updated On:30-Aug-2011 11:02:35 UTC
Expiration Date:30-Aug-2012 11:02:35 UTC
Sponsoring Registrar:Regtime Ltd. (R1602-LROR)
Status:TRANSFER PROHIBITED
Status:ADDPERIOD
Registrant ID:CO1014850-RT
Registrant Name:ALex Potolot
Registrant Organization:ALex Potolot
Registrant Street1:49-12 Shepherd Street
Registrant Street2:
Registrant Street3:
Registrant City:London
Registrant State/Province:London
Registrant Postal Code:W12 7HF
Registrant Country:GB
Registrant Phone:+44.2073290240
Registrant Phone Ext.:
Registrant FAX:
Registrant FAX Ext.:
Registrant Email:apotolot@yahoo.com

It's kind of odd that a German police domain should be registered to a person in the UK using a free email address. But what is odder is that the address does not exist. Although there is a Shepherd Street in London, the postcode is not W12 7HF, that's the postcode for Stanlake Road in Hammersmith. Shepherd Street's postcode begins W1J 7Jx in any case, and there's no number 49 on that road (it is approximately the location of the Park Lane Mews Hotel).

Let's check the nameservers:
Name Server:NS1.NAMESELF.COM
Name Server:NS2.NAMESELF.COM
Nameself.com is DNS service for Russian registrar WebNames.ru. (aka Regtime Ltd) who are also the domain registrar. Why would the German police use a Russian registrar?

The next clue is in the MX handlers - these are the servers that handle mail for dpolg-bundespolizei.org:

  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 20 ALT1.ASPMX.L.GOOGLE.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 20 ALT2.ASPMX.L.GOOGLE.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 30 ASPMX2.GOOGLEMAIL.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 30 ASPMX3.GOOGLEMAIL.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 30 ASPMX4.GOOGLEMAIL.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 30 ASPMX5.GOOGLEMAIL.COM
  dpolg-bundespolizei.org MX (Mail Exchanger) Priority: 10 ASPMX.L.GOOGLE.COM
So, the domain is using Google for mail handling. DPolG use their own mailservers, not Google.

Something is definitely amiss here, and it wouldn't be the first time that the Bundespolizei name was used for malicious purposes as there has been a recent rash of malware using it. On balance, a domain with a fake UK address registered via a Russian registrar and using Google for mail handling is unlikely to be legitimate. Avoid.

Fake jobs: consult-position.com, instant-job.com, newweb-career.com, uk-bestjob.com and web-newcarer.com

A new set of domains pushing illegal money laundering jobs and other criminal activities as part of this long running operation.

consult-position.com
instant-job.com
newweb-career.com
uk-bestjob.com
web-newcarer.com


Typically, these emails will appear to be "from" you as well as "to" you.. this is just a forgery and it doesn't mean that your mail is hacked.

Don't be tempted by the jobs on offer, typical positions are for money mules, reshipping scams or sometimes back-office functions such as translating emails or signing paperwork. Don't bother replying to the email as no good will come of it.

If you have an example of any emails using this address, please consider sharing it in the Comments. Thanks!

Friday, 26 August 2011

Fake jobs: us-newcareer.com

Operating the same money laundering scam/spam as this batch of domains, and forming part of this very long running scam, the domain us-newcareer.com was freshly registered two days ago.

The jobs offered by anyone soliciting replies to this email address are all criminal activities and should be avoided. The spam email messages may appear to be coming from your own email address, but this is a simple forgery and it does not mean that your computer or mail account is compromised.

If you have examples of spam emails using the domain, please consider sharing them in the Comments. Thanks!

Wednesday, 24 August 2011

Fake jobs: greece-career.com, il-career.com, mc-jobs.com and oae-career.com

Four new domains peddling fake jobs today, forming part of this very long running scam.

greece-career.com
il-career.com
mc-jobs.com
oae-career.com

The "jobs" offered are actually criminal activities such as money laundering. It may be that the email appears to come "from" you as well (the from address is trivially easy to fake, it doesn't mean that your machine is infected with anything).

Domains were registered two days ago to "Alexey Kernel", which is no doubt a fake name.

greece-career.com presumably targets Greek nationals, and il-career.com looks to be targeting Israelis. The other two are less clear, but our best guess is that mc-jobs.com might be targeting Macedonia (but the TLD is .mk) and oae-career.com might be the UAE and is just a typo. This continues the pattern of going after non-English speaking victims who might be fooled more easily by a scam email in their own language.

If you have any examples of this spam, please consider sharing them in the Comments. Thanks!

HMRC phish: refund1-hmrc.com, refund2-hmrc.com, refund3-hmrc.com and refund4-hmrc.com

Here's a bunch of web sites and domains being used to peddle fake HMRC (UK tax office) refunds:

www.refund1-hmrc.com
www.refund2-hmrc.com
www.refund3-hmrc.com
www.refund4-hmrc.com
www.handler123.com

The fake emails look something like this:

From: HM Revenue & Customs Billing Department [mailto:hmrc@refund1-hmrc.com]
Sent: 22 August 2011 09:36
To: [redacted]
Subject: Billing Notifcation

Total refund amount: 478 GBP

To ensure that your service is not interrupted, we request you to confirm and update your information today by following the link below:

Refund Notification


Thank you for your prompt attention to this matter. Do not reply to this e-mail.

Member [redacted]

© HM Revenue & Customs 2011 

The emails actually come from  refund1-hmrc.com, refund2-hmrc.com, refund3-hmrc.com and refund4-hmrc.com so

If you click through the link then you get a pretty standard phishing page trying to get credit card details, personal information and passwords.

The HMRC don't send tax refund messages by email, so any such notification should be considered bogus.

The phishing sites are hosted on 211.154.91.246 in China, blocking that IP would be a good idea, but you could go further and block 211.154.64.0/19 as it looks like a cable modem range and there shouldn't really be any legitimate sites hosted here.

Domain registration details are clearly fake:


Domain Name.......... refund1-hmrc.com
  Creation Date........ 2011-08-22
  Registration Date.... 2011-08-22
  Expiry Date.......... 2012-08-22

The nameservers are hosted on 200.29.238.90 in Colombia (CONSULNETWORK LTDA).

Fake jobs: unionhire.net, wugcareer.com and wugoffers.net

Three new fake job domains registered in the past couple of days to the fake "Alexey Kernel" registrant, forming part of this very long running scam.

unionhire.net
wugcareer.com
wugoffers.net


As before, there is a series of spam messages advertising so-called "jobs" from these companies, but in reality they are criminal activities such as money laundering.

If you have a sample email, please consider sharing it in the Comments. Thanks!


Something evil on 95.168.177.144: reddingtaxcm.com and inferno.name

reddingtaxcm.com is a legitimate domain that is registered at GoDaddy and has been hijacked to serve up malware, hosted on 95.168.177.144 (NetDirekt, Germany but more below..).

The malware appears to be a variant of Vundo / Virtumundo, the infection mechanism looks to be some sort of injection attack on third party sites.

Although the IP 95.168.177.144 is allocated to NetDirekt (now Leaseweb Germany), it belongs to part of a range suballocated to inferno.name of Serbia (apparently also known as v3Servers.net). Inferno featured recently in this blog with another similar malware attack, that time on 95.168.178.206. 95.168.177.0/4 seems to be full of (possibly fake) pharma sites.

A lot of other IP addresses associated with this company are implicated with forum spamming.

Just in case you want to block traffic to/from inferno.name (although there may well be legitimate sites and servers in these ranges) then I have identified the following IP ranges, although there may well be more:

46.22.211.0/25
80.79.124.128/26
92.48.122.32/28
95.168.165.0/24
95.168.173.0/24
95.168.177.0/24
95.168.178.0/24
95.168.191.0/24
188.72.204.0/24
188.72.213.0/24
188.143.232.0/23
212.95.54.0/24
212.95.58.0/24
212.95.63.0/24

As for 95.168.177.144, watch for traffic going to subdomains of reddingtaxcm.com, for example:

command0.reddingtaxcm.com
danger0.reddingtaxcm.com
costs0.reddingtaxcm.com

Something evil on 79.133.196.124

I don't quite have the full picture on this, but it looks like some Scandinavian sites have been compromised in some way and are redirecting to a malware server on 79.133.196.124 in Poland which is serving up fake AV applications.

Blocking access to 79.133.196.124 is probably a very good idea. The following sites appear to be hosted on that server and should be blocked if you can't do so by IP address, alternatively just block access to all .co.cc and .rr.nu domains if you can.

virtualmapping.org redirect

The domain name virtualmapping.org sounds legitimate, but isn't.. it's a redirector used on hacked websites. The first time you visit one of these hacked sites via a Google search, you get redirected to a URL at virtualmapping.org/cgi-bin/r.cgi. Subsequent visits don't seem to trigger this, nor does visiting the site directly. It could be an altered .htaccess file.

virtualmapping.org is hosted on 94.63.149.246 which is unsurprisingly enough in Romania, in a Cobalt IT SRL block suballocated to SC Coral IT Office SRL / xnetworkings.com also in Romania. Sites in these Cobalt ranges are either all evil or are of interest to Romanian visitors only, so one quick and easy way to secure your network is to block the entire 94.60.0.0/14 range.. at the very least, block 94.63.149.0/24, 94.63.244.0/24 and 94.60.123.0/24 which are especially toxic.

After hitting virtualmapping.org, visitors are then redirected to one of the following sites on 95.168.178.206, hosted at Netdirekt in Frankfurt but actually allocated to a host called inferno.name (Sogreev Anton, Serbia). 95.168.178.0/24 is full of Russian porn sites, so probably a good thing to block in any case.

Some of the domains that are loading the malware are:
could0.nc-9.com
gets1.nc-9.com
realized2.nc-9.com
summer3.nc-9.com
principle4.nc-9.com
watching4.nc-9.com
and5.nc-9.com
electric6.nc-9.com
plane6.nc-9.com
show7.nc-9.com
fig8.nc-9.com
ever8.nc-9.com
feet8.nc-9.com
league9.nc-9.com
event9.nc-9.com
became0.nc-9.com
sense4.nc-9.com

Basically, anything in the nc-9.com domain apart from nc-9.com and www.nc-9.com has been hijacked and is pointing to the IP address in Frankfurt. It's not a surprise to see that nc-9.com is actually a legitimate domain registered at GoDaddy that appears to have been hijacked.

The payload is a nasty trojan according to various analysis tools (ThreatExpert, Comodo, Anubis). Detection rates are very low. The analysis tools might help you to clean up your PC if you have somehow become infected.

Of some interest, the trojan alters the HOSTS file to block access to popular torrent sites such as the Pirate Bay. It also calls home to two domains, assistancebeside.com (78.159.100.32) and imagehut4.cn which was actually deleted last year, but was registered to the scumbags at Real Host Ltd.

There's quite a lot to block here, the highest priorities are:
94.63.149.246
95.168.178.206
78.159.100.32
*.nc-9.com
assistancebeside.com
virtualmapping.org

I see no harm in blocking the following /24s:
94.63.149.0/24
95.168.178.0/24

And if you're not afraid to block really quite large address ranges:
94.60.0.0/14

Fake jobs: careers-canada.com

One fake job domain today, and the scammers seem to have shifted to a new target - Canada. This time, the domain is careers-canada.com, registered only yesterday to the fictitious "Alexey Kernel" in the Ukraine.

The standard approach with these scammers is to spoof an email "from" the target's email address (don't worry if you see this, your email account has not been compromised) and the emails offer a variety of illegal jobs including money laundering. It forms part of this long-running scam.

If you have any examples of emails using this domain, please consider sharing them in the Comments.. thanks!
