"Faster payment" scam is not quite what it seems

I see a lot of "fake boss" fraud emails in my day job, but it's rare that I see them sent to my personal email address. These four emails all look like fake boss fraud emails, but there's something more going on here.

"Andrea" and "Ravi" are not random people, they are both directors of a legitimate company with a name very similar (but unconnected) with one I blogged about years ago. In $dayjob the sample email I saw was from that company's chief counsel, so I believe these are targeted but just incorrect.

Normally with this sort of scam, the "boss" is asking for payment to be wired to the bank details in the email. But in this case, the sort codes for the banks (30-62-12, 30-61-10 and 30-62-15) don't exist. If you tried to wire money to them, the transfer would fail.

So, presumably when the bank transfer fails, the victim emails back the "fake boss", but it isn't all it seems. Although the "From" address looks to be genuine, there's a "Reply-To" address which goes to something a but more subtle.

For example in one of the examples about the email appears to come from andrea@victimdomain.com (i.e. whatever the victim's genuine domain is) but replies go back to something similar but different, for example andrea@victimdomain.com-v.eu - at which point the fraudsters probably then come up with different bank account details.

At the moment the email replies go to a server at 185.235.131.65 (hostname uk-v.eu) in the Netherlands, but these domains and servers get shut down quickly.

All these following domains are linked to the scam (there are probably more):
uk-0.eu
uk-1.eu
uk-2.eu
uk-3.eu
uk-4.eu
uk-5.eu
uk-8.eu
uk-9.eu
uk-f.eu

com-2.eu
com-3.eu
com-4.eu
com-5.eu
com-6.eu
com-7.eu
com-8.eu
com-f.eu
com-v.eu

This variation of an old scam seems to be quite new. Remember, if your boss emails you out of the blue and asks you to set up a payment without giving much information, always check that the request is valid and don't simply reply to the email.

What I hadn't noticed before is that the spam is using homoglyphs in the text to avoid filters. For example, the word "pаymеnt" in the email above does not acutally say "payment", but it uses a couple of cyrillic (i.e. Russian) characters in place of the "a" and "e" that just look the same.


For the latest spam messages, the email relays through various hosts but always seems to originate from 91.243.80.176 (hostname: lmasko22.example.com). As with the other infrastructure this belongs to a company called MoreneHost in Russia.

Swisscoin [SIC] cryptocurrency spam

Swisscoin is a fairly low-volume self-styled cryptocurrency that has been the target of a Necurs-based spam run starting on Saturday 13th January, and increasing in volume to huge levels on Monday.

From:    Florine Fray [Fray.419@redacted.tld]

Subject:    Could this digital currency actually make you a millionaire?

Every once in a while, an opportunity comes around. What divides winners from losers is those who seize it and those who don't. By now, you must have heard about all the people who made a killing with bitcoin over the last year. Some of them made more than ten million with just an initial purchase of a thousand bucks. What I want to ask you though is: Did you know that there are hundreds of other digital currencies that have had even bigger gains over the last twelve months? This includes Ripple, Ethereum and Raiblocks – you may have heard about some of them. What is the next big one for 2018? The answer in my opinion is simple. It's Swisscoin [SIC]. The reason for that is very straight forward. It's because it is supported by the Switzerland government. It is already considered as legal in the country and it is entirely shielded from any political instability. It's the type of coin that you can buy a thousand bucks of, and sit on for a few months or even years and that few thousand will likely be worth a few million. SIC has already doubled in value since Saturday and it will double or triple again by this Friday. So, what are you waiting for? For the time being it can only be purchased on /coinexchange [dot] io/ (that's the website address of the exchange). You can set up an account in about thirty seconds, then you send bitcoins to it and you can easily buy swiss coin. If you don't have any bitcoin already you can just google how to get some, it's super simple and will just take you 10 minutes at most, then transfer them to coinexchange's website and get the SIC

Subject:    This crypto coin could go up fifty thousand percent this year

Dear [redacted],

If you don't already own a few coins of something, then surely at the very least, you must have heard about cryptocurrencies.

Bitcoin, the most famous one, minted countless multimillionaires but did you know that altcoins (bitcoin alternatives) are responsible for even more riches?

Among the "big" ones, NEM went up almost 10,000 percent and Ethereum, more than 4,000 percent

Among the small and unknown ones several gained more than 50,000 percent.

To put this in perspective, a small 1,000-dollar coin purchase in one of these small ones could have turned into more than 50 million bucks.

It seems crazy, doesn't it? Well, it's the reality of the cryptocurrency market today.

Raiblocks, a relatively obscure coin at the time, went from 0.20 on December first to $20 by New Year's Eve. It is now in the top 20 largest coins in the world.

All that to say, the next big winner could be found anywhere, and today I believe I've identified the next one.

After spending hundreds of hours looking at hundreds of different coins, I locked down on one specific target.

Swisscoin.

As the name says, this is a coin created and headquartered in Switzerland. It is one of the only coins in the world recognized as legal tender by the government.

Swisscoin is allowed by the Swiss government and has the potential to climb more than 5,000% before the end of January and more than 50,000% before the end of this year.

This is one of those rare buy-and-hold coins which you WANT to own, and hang onto for the long term, much like those people who bought bitcoin at $1 and kept it for 3 years. FYI, bitcoin is trading at $14,000 now. That's an increase of over 1 million percent.

I recommend you consider putting at least a thousand bucks in Swisscoin immediately. This could quickly turn into enough money to buy a new house, or at the very least a new car.

For those of you who already have bitcoins, all you need to do is open an account at coinexchange.io (this is the url/website, and it takes 1 minute to get setup), transfer some btc to your new account and buy SIC (Swisscoin).

For those of you who are still clueless about Cryptos, the process will be a little bit longer but well worth it.

Open an account at a large exchange such as Coinbase dot com or Coinmama dot com, then add some fund using your credit/debit card or Paypal.

That's the fastest way, but you will be limited to a few hundred bucks at most. It should be enough to get you quickly started but consider adding more funds using a bank transfer so that you can really have skin in the game.

Remember, every thousand bucks of SIC you buy today could easily turn into 500,000 by this time next year.

Subject:    Let me tell you about one crypto currency that could turn 1000 bucks into 1 million

If you took a chance on bitcoin early on, just a few years ago, your investment could have paid off in a big way.
According to digital-currency website CoinDesk the value of bitcoins was volatile at the beginning.

It was possible to purchase a single bitcoin for just a few cents. Had you bought just a thousand bucks' worth you would be sitting on millions right now.

Want to know what's even crazier? These types of returns have been replicated hundreds of times over so many different alternative coins and it continue happening all the time.

The trick is to buy into a coin very early on before the crowds notice it.

My research shows that Swisscoin (SIC) is going to be the next big one to blow up this year. It has already doubled since yesterday and as the trend continues it could be 10 times as high before the end of the coming week.

Swisscoin is one of the only coins approved by the government in Switzerland. It is 100% legal and useable in everyday life.

Switzerland's Swiss Franc has been one of the most stable and best performing currencies throughout history and Swisscoin aims to replicate this standard with the digital coin.

Could you turn a thousand bucks into a million before the end of 2018 with SIC? The answer is a clear yes.

For the time being SIC only trades on one exchange: coinexchange.io so you need to open an account there (takes about thirty seconds), and transfer bitcoin to it so you can make the purchase.

If you don't own any digital currency yet then you need to open an account at coinbase or coinmama and buy some btc (bitcoin) with your credit or debit card or bank account.

After you get bitcoins, just follow the instructions in the above paragraph.

One thing is for sure, you definitely don't want to miss out on Swisscoin.
Swisscoin trading was recently suspended and only started up again a few days ago. The chart at World Coin Index shows that this has been a real rollercoaster ride.



There are questions as to whether Swisscoin is actually a cryptocurrency or a Ponzi scheme. Honestly, I don't know and I'd advise you to do your own research. However, this has all the markings of a pump-and-dump scheme, so it's quite possible that someone who bought Swisscoins at their peak wants to pump the price up so they can sell off their holdings. Given that the spam is being sent out from a network of hacked machines and does not comply with anti-spam laws, you can pretty much guarantee that this is not legitimate and should be avoided.

UPDATE: a subsequent spam run looks like this:

Subject:    Forget about bitcoin, there's a way better coin you can buy.

It's probably not news to you at this point if I tell you that bitcoin has made tons of people tons of money. Something else you probably already know is that it will never go up like crazy again. Its time to shine is long gone. That's why we must look into what the next big thing is, and the truth is that there have been plenty over the last few months. Can you jump on the next huge one before it soars? Swiss coin {SIC} is the most likely candidate for a fifty thousand percent return this year. It has the support of the Switzerland government. It is already considered as legal in the country. It's the type of coin that you can buy a thousand bucks of right now, sit on for a small period of time and you could make out crazy wealthy when all is said and done. SIC has already doubled since Saturday. This long Martin Luther King weekend could bring you even more upside if you act quickly. For those of you who know what this means… you can get it for under 50 satoshi right now. And if you have no clue what this means, it basically means that you can get in on the ground floor How do you get some? You just need an account at coinexchange.

Some random thoughts on Damian Green and those porn allegations

If you live in the UK then you might have noticed the somewhat bizarre furore over Damian Green MP and his alleged viewing of pornography on house his Parliament computer. Now, I don't know for certain if he did or didn't, but to put it in context his private email address also allegedly turned up in the Ashley Madison leak and on top of that there are sexual harassment allegations too. But let's stick to the porn for now.

Anybody who has been involved in forensic investigations of computers may well understand these comments:

Mr Lewis, who retired from the Metropolitan Police in 2014, said although "you can't put fingers on a keyboard", a number of factors meant that he was sure it was Mr Green, the MP for Ashford, Kent, who was accessing the pornographic material.

His analysis of the way the computer had been used left the former detective constable in "no doubt whatsoever" that it was Mr Green, who was then an opposition immigration spokesman but is now the first secretary of state.

"The computer was in Mr Green's office, on his desk, logged in, his account, his name," said Mr Lewis, who at the time was working as a computer forensics examiner for SO15, the counter-terrorism command.

"In between browsing pornography, he was sending emails from his account, his personal account, reading documents... it was ridiculous to suggest anybody else could have done it."  
To put this into context - the computer was seized in 2008 when Green was arrested over the suspected leaking of confidential material. Any investigation such as that will look at web browsing history, recently accessed or saved documents, cookies, bookmarks and stored documents and images. So, it is utterly credibly that the investigation would have found this type of activity if it had occurred.

Indeed, there seems to be no denial that this material had been accessed on the computer, but that Mr Green had not done so. But Mr Lewis's statement also says that things such as private email were accessed concurrently. If you were carrying out an investigation on behalf of a business, then this would indeed be enough to "place fingers on a keyboard".

But here is the surprise - why would this material be accessible at all? Nobody has claimed that it was not accessed, just that Mr Green himself did not access it. But any reasonably-sized business would usually have some sort of filter to stop this happening.

The House of Commons by itself employs over 2000 people. Add to that the staff of the House of Lords, the Lords themselves, MPs and other staff who are not directly employed by either House then you are looking at thousands of employees. That's quite a large organisation, and if there is no effective web filtering for any of them, then that introduces a serious security risk.

Anybody who works in IT in a relatively large organisation such as this will know that at least some of them will try to access pornography. My experience is that people who do this on their work computers are exclusively male, and there are 453 male MPs in the House of Commons. This is certainly a large enough group for some of them to be accessing porn, at least some of the time/


So we can surmise a couple of things - it certainly seems to be possible to access porn from a Parliament computer, and given the number of people working there it seems likely that somebody would try. The number of male MPs certainly seems enough for one of those to try to access porn. Given that it is likely that some of them try, there's no particular reason why it shouldn't be Damian Green. And if one MP is fired from his job because of porn, then you can bet there are other MPs who have done the same thing.

But why not implement some sort of filtering? The problem is that MPs are not employees - Parliament is the primary legislative body in the UK and it is essentially sovereign (despite there being a Queen). Imagine that you worked in an organisation where there were hundreds of C-level executives, and then try to police them from an IT point of view. MPs are probably amongst the worst users in the world to support.

As I said, most organisation of any size filter porn from corporate computers. Strategically, the main reason to do that is not to track down and fire errant employees, but to prevent embarrassment to that organisation. It's all very well to fire a low-level employee for viewing smut, but when it comes to the top of the food chain such terminations can also be damaging to the reputation of the organisation itself. If Parliament isn't filtering this sort of material then it is always likely to end up with this sort of scenario from time-to-time.

Mr Lewis's comments indicate that the material was found on the computer itself, not a proxy log or other external system. It's quite possible that whoever was accessing the material on Mr Green's computer could have saved themselves a lot of grief if they'd used private browsing (although a deep forensic investigation can often find artifacts even when this has happened).

Also, Nadine Dorries MP did state that she shared her password with staff who worked for her. This is terrible practice, and certainly in my organisation if you share your password and somebody abuses it, then you are liable for anything that they did.

Don't forget as well, the habit of porn sites infecting visitors with malware though malicious advertisements, and the habit of more "specialist" sites having been created specifically to infect visitor's computers. MPs might not think themselves to be important enough to hack, but they will have private correspondence with constituents and other parties that should remain private.. and not be leaked out.

Whatever the truth of Damian Green's surfing habits, it looks like Parliament is badly in need of proper regulation of its computer systems. But you really do have the nightmare users from hell in that job. I suspect it is going to take something more that one embarrassed MP to force a change.

may be insecure and could be worth blocking.

The email itself originates from 104.171.114.204 which is allocated as follows:

You probably don't need to accept .z attachments at your mail perimeter, and any decent anti-spam tool should be able to look inside archives to determine was is in there.

Evil network: Fast Serv Inc / Qhoster.com

Checking these IOCs for this latest Flash 0-day came up with an interesting IP address of 89.45.67.107 which belongs to Fast Serv Inc aka Qhoster, probably of Bulgaria but masquerading themselves as a Belize outfit.

I came across Fast Serv / Qhoster a lot last year during the Angler EK epidemic, where they had entire ranges full of badness, often with no discernable legitimate sites at all. It turns out that I'd blocked the /24 a year ago as it was full of EK servers. The full analysis I did of Fast Serv / Qhoster Angler ranges can be found in these Pastebins: [1] [2] [3] [4] [5] [6] [7]

So, this Flash 0 day gave me a renewed impetus to identify these ranges and keep them the hell off my network. Luckily HE's BGP tool can identify most of the allocated IPs of a /24 size or larger [8] [9] plus a bit of infill from other sources.

I can't guarantee that these ranges are free of legitimate sites, but even a quick glance at some of the ranges (the BGP tool is quite good for this [10]) shows signs of obvious badness in almost all of them. Use at your own risk :)

Note that these ranges are across many different ASes and hosts, although AS201630 is allocated to Qhoster themselves.

There are lots of suspect things about this domain registration - the address is clearly fake, the registrar is based in South Africa and the nameservers are in Russia, and also it was registered just a few weeks ago. A quick bit of Googling around shows that "Nelson Ozi" is also linked to the following probably fraudulent domains:

svbfib.com
svbfibem.com
globalcreditsus.com

These all seem to be connected with an IP range 169.255.59.0/24 (Web4Africa again) which does seem to have a lot of scammy sites hosted on it. Blocking access to that range might be prudent.

The spam email itself comes via another Russian server mail.elmeh.ru but this particular email originated from 103.207.37.101 in Vietnam. Replies to the champ-footballacademyagency.co.uk email would be set to mx.yandex.net which is in Russia again.

It would probably be quite difficult to stuff any more dodgy indicators into this spam. What the scam actually is isn't 100% clear, it could be anything from a simple advanced fee fraud all the way up to child abduction. Avoid.

Inside is a malicious VBS script (example) which exhibits a curious feature:


If you are in the UK, Australia, Ireland, Belgium or Luxembourg you get one binary [VT 12/64], everyone else gets another [VT 20/64]. My Online Security describes this in more detail - the first group get the Trickbot banking trojan and everyone gets Locky ransomware.

In the samples I saw, the Trickbot download locations were:

There may be other locations too.

The following legitimate services are used for geolocation. They might be worth monitoring:

https://ipinfo.io/json
http://www.geoplugin.net/json.gp
http://freegeoip.net/json/


All these recent attacks have used .7z archive files which would require 7zip or a compatible program to unarchive. Most decent mail filtering tools should be able to block or strip this extension, more clever ones would be able to determine that there is a .vbs script in there and block on that too.

Attached is a .7z archive file with a name that matches the one quoted in the subject line. So far I have seen just two versions of this, each containing a malicious script (sample here and here). These scripts have a detection rate of about 13/58 and they can been seen attempted to download a component from:

The name of the sender varies. Attached is a .7z arhive file with a name similar to A2174744-06.7z which contains in turn a malicious .vbs script with a random number for a filename (examples here and here).


Automated analysis of those two samples [1] [2] [3] [4] show this is Locky ransomware. Those two scripts attempt to download a component from:

QTUM Cryptocurrency spam

This spam email appears to be sent by the Necurs botnet, advertising a new Bitcoin-like cryptocurrency called QTUM. Necurs is often used to pump malware, pharma and data spam and sometimes stock pump and dump.

There is no guarantee that this is actually being sent by the people running QTUM, it could simply be a Joe Job to disrupt operations. Given some of the wording alluding to illegal marketplaces, I suspect this could be the case.

Subject:       Qtum Main Network Launches September 13th, 2017
From:       "Lou Roberson"
Date:       Wed, September 6, 2017 6:37 am

The Blockchain Made Ready for Business
Build Anonymous Decentralized Applications that Simply Work
Executable on mobile devices, compatible with major existing blockchain
ecosystems
TESTNET NOW LIVE!
   
    About
     
The Qtum Foundation is a Singapore based entity that promotes
adoption of the Qtum Blockchain. Project inception began in
March 2016, leading up to a successful crowdsale a year later.
Over 10,000 BTC and 72,000 ETH were raised in less than 5 days,
making Qtum one of the largest crowdfunded projects in history,
at $15.6 million dollars.

Investors received 51,000,000 Qtum tokens which will be
available for withdrawal on September 13, 2017.


The Qtum Foundation plans to be the anonymous blockchain for
business. Development efforts will allow us to market this
platform tovarious industries, such as: Mobile
Telecommunications, Counterfeit Protection, Finance, Industrial
Logistics (shipping, warranty,etc), Manufacturing, P2P Anonymous
Transfers and Anonymous Market Management from phone.
Build anonymous decentralized applications you can trust
     
Smart Contracts that Mean Business
Qtum makes it easier than ever for established sectors and
legacy institutions to interface with blockchain technology.
Create your own tokens, automate supply chain management and
engage in self-executing agreements in a standardized
environment, verified and tested for stability.

   
    Specification

    Total QTUM Supply: 100,000,000
    Block Target: 128 seconds
    Stake Return: ~4 QTUM
    Algorithm: SHA256

Sparknet is designed primarily for developers, and as such
documentation at this point will be technical and suited more
for developers.  Testnet tokens do not hold any value and should
not be traded for any monetary instruments. The testnet can be
reset or forked at anytime as deemed necessary for development.

Forum Announcement:
https://bitcointalk.org/index.php?topic=1720632.4220

Release on github:
https://github.com/qtumproject/qtum/releases/tag/testnet-sparknet

    QTUM SPYNET

Aug 15 The 2nd Qtum Test Network, Skynet, is now live: SKYNET
   
     
Qtum Skynet, the second public testnet for the Qtum blockchain.
All tokens aqcuired during the testnet will cease to exist 
when the mainnet is released which actually has tokens which
hold value. The purpose of the public testnet is to allow
developers to begin testing and developing applications, allow
early adopters to see a preview of how the network will behave,
and for the Qtum development team to run several load tests
which are not directly comparable when done on a private and
controlled network. Qtum Skynet will ideally have the same
consensus features and parameters as the Qtum mainnet.


Qtum Skynet Usage and Information:
Please see:
https://github.com/qtumproject/qtum/releases/tag/testnet-skynet
Please see:

As soon as Main Network will be launched, you will be availaible
to build your own applications (DApps) or marketplaces. Fully
scalable and anonymous, so you can easy made any anonymous
marketplace which can be manage from your phone!

Just imagine, your own silkroad made on Qtum blockchain and
managed from your phone with fully anonymous transactions!

    No matter what kind of business you are building, all
transactions will be anonymous, and the network will never
reveal the ip addresses of the applications that are running
on it.

    Even if you sell weapons, drugs, trade in people and are
going to organize a coup d'?tat, you can be sure that you
will remain anonymous.

    Another thing is that it is illegal and sooner or later you
will receive the punishment that you deserve. But everyone
want to know how deep the rabbit hole goes.

    For our part, we can only provide a reliable, scalable and
anonymous ecosystem thanks to which any business can be
built on it and we guarantee that we will do everything
possible to make it sucesfull.

    We give you a choice - "blue pill or red pill"
       
        What Will your choice be?

    So, you have to prepare for Main Network launch  Qtum Custom
Token Walkthrough
   
    CROWDSALE
     
The QTUM token supply will be allocated as follows:

    - 51% of Qtum tokens (51,000,000) will be distributed
through the crowdsale
    - 20% of Qtum tokens (20,000,000 QTUM) will be distributed
among founders, early backers and the development team
    - 29% of Qtum tokens (29,000,000 QTUM) will be allocated to
community initiatives concerning business development, as
    well as academic research, education, and market expansion

As far as I can see, there are no malicious links anywhere. This one can probably be marked down as an annoyance, and it should be easy enough to block or filter.

Malware spam: "Scanning" pretending to be from tayloredgroup.co.uk

This spam email pretends to be from tayloredgroup.co.uk but it is just a simple forgery leading to Locky ransomware. There is both a malicious attachment and link in the body text. The name of the sender varies.

Despite having what appears to be a Dropbox URL, the link actually goes to another site completely and downloads a .7z archive file containing a malicious VBS script. Attached is another .7z archive file with a slightly different evil VBS script inside.

Detection rates for the scripts are about 13/58 [1] [2]. Automated analysis [3] [4] [5] [6]  shows Locky ransomware attempting to phone home to the following locations:

91.234.35.170/imageload.cgi (FOP Sedinkin Olexandr Valeriyovuch aka thehost.ua, Ukraine)
109.234.35.75/imageload.cgi (McHost.ru / VDSINA, Russia)

McHost is such a well-known purveyor of toxic crap that I recommend you block all of their ranges (plus I guess the related VDSINA ones), or even block the entire Webzilla AS35415. You can find a list of the network ranges here. Also thehost.ua also has a lot of crap and I would lean towards blocking whole network ranges.

Recommended minimum blocklist:
91.234.35.0/24
109.234.35.0/24

Malware spam: "Voicemail Service" / "New voice message.."

The jumble of numbers in this spam is a bit confusing. Attached is a malicious RAR file that leads to Locky ransomware.

Subject:       New voice message 18538124076 in mailbox 185381240761 from "18538124076" <6641063681>

Dear user:

just wanted to let you know you were just left a 0:13 long message (number 18538124076)

so you might want to check it when you get a chance.  Thanks!

Attached is a RAR file containing a malicious VBS script. The scripts are all slightly different, meaning that the RARs are too. These are the MD5s I've seen so far for the RAR files themselves:

The VBS script is similar to this (variable names seem to change mostly) with a detection rate of about 15/59. Hybrid Analysis shows it dropping a Locky executable with a 18/65 detection rate which phones home to 46.17.44.153/imageload.cgi (Baxnet, Russia) which I recommend that you block.

Malware spam: "Your Sage subscription invoice is ready" / noreply@sagetop.com

This fake Sage invoice leads to Locky ransomware. Quite why Sage are picked on so much by the bad guys is a bit of a mystery.

The link in the email downloads a malicious RAR file. The samples I saw were closely clustered alphabetically.

The RAR file itself contains a malicious VBS script that looks like this [pastebin] with a detection rate of 19/56, which attempts to download another component from:
