My hope is that when people become familiar with the tactics employed by scammers, they will be less likely to get ripped off. With this in mind, I'd like to describe my recent interactions with miscreants who target sellers on Craigslist. Perhaps the details I've gathered about the scammer's operation will help curtail such activities. This encounter, which involved SMS messages, emails and a click, is a variation of a PayPal-themed overpayment scam that has been quite prolific in the recent years.

"Working in a very rural area"

The text message from 731-907-0226 arrived in response to my Craigslist post that advertised a furniture item for sale. "Text me back at (7312777303 if you still have it, am interested. Text only". My ad included a temporary phone number I set up just for cases like this. Responding to the sender of this message produced no reply; however, when I texted 731-277-7303, I received a quick answer:

"My name is Rick Smith. I am buying this as a surprise,I work with Turner Construction,we are currently working at a very rural area which makes it very hard for me to make phone calls. I have a Mover who will come for the pickup, I will be making the payment via PayPal that is the only payment option."

This message achieved two critical objectives for the scammer. First, the person began crafting a story that will later provide an excuse for asking the victim to wire funds to a third party. In addition, the scammer was establishing a reason why he could interact with me using voice calls. The supposed buyer was claiming to be in an area where voice calls didn't work. In another variation of a Craigslist-originating scam, scammers used the excuse of being on active duty in the military, which precluded non-text communications. Scammers might shy away from phone calls, in part because interacting with multiple targets this way is time-consuming; also, calls might reveal too many details about the scammer.

The scammer also requested my email address, so he could send me payment. He insisted that PayPal was the only payment method he could accommodate. As is common in schemes that target Craigslist users, the scammer didn't want to contact the victim using the Craigslist email relay, probably to avoid getting blocked by that system.

The scammer's phone numbers above were associated with the VoIP company Bandwidth.com, which makes its virtual numbers available to other providers, such as Google Voice according to Phone Validator.

"You are required to send the $680.00"

After I supplied my email address, which I set up for interactions like this, I received a reply:

"Please check your email for the notification and instructions,but if you don’t get the notification in your inbox please check the spam. PayPal must have sent you some emails by now, I think you need to follow some steps. please check both spam/junk and inbox and get back to me ASAP."

Indeed, my Hotmail inbox included a message with the subject "Notification Of An Instant Payment From Rick Smith(brwnsmith20@gmail.com)". Although it was designed to look like it came from PayPal, its headers told a different story:

Authentication-Results: hotmail.com; spf=pass (sender IP is smtp.mailfrom=joylove270@gmail.com; dkim=none header.d=consultant.com; x-hmca=none header.id=Email.transactionverifier@consultant.com
X-SID-PRA: Email.transactionverifier@consultant.com
Sender: joylove270@gmail.com
From: "Service@PayPal.com" <email.transactionverifier@consultant.com>
Date: Sun, 30 Aug 2015 19:20:59 +0100
Subject: Notification Of An Instant Payment From Rick Smith(brwnsmith20@gmail.com)
Return-Path: joylove270@gmail.com

The headers confirmed that the message was sent using Gmail ( belongs to Google). The actual sender was joylove270@gmail.com.

All emails I received from the scammer had the Date: stamp that included the +0100 time zone designation, lending some credence to the hypothesis that the person was sending the messages from a Central European Time (CET) country.

The notice listed the buyer's as brwnsmith20@gmail.com, which might be an artifact carelessly left from an earlier version of the scam. The email indicated that the supposed payment was significantly larger than what I had requested on Craigslist. It included an explanation for this overpayment:

"Rick Smith has made his intentions known to PayPal® that he will like $680.00 USD to be sent to the recipient's address below.You are required to send the $680.00 USD via Money Gram Money Transfer."

This was a setup for the overpayment scam, in which victims are persuaded to pay a third-party on behalf of the miscreant.

"We are working with Money Gram on this transaction."

Despite the (fake) email confirmation of payment, no funds were actually deposited into the PayPal account I set up for such interactions. When I asked the "buyer" about this discrepancy, he explained:

"As per the e-mail PayPal sent to me which is also similar to yours which i hope you receive, you will have to pay an upfront payment out of your pocket via Money Gram to the address given to you, and you will be given the information which is the Reference Number you will email to PayPal by replying to the confirmation mail from them regarding the details you have from Money Gram, you will receive the whole money in your account without any delay."

The fake PayPal message in my inbox clarified that I might not see the funds in my PayPal account until I sent money to the buyer's pickup agent using MoneyGram. The email provided further assurances:

"The money has now been deducted from the buyer's account and is ready to be deposited into your PayPal® account. Please reply this email directly with the Information needed from you. While funds are pending, the money belongs to you but is not available to spend or withdraw."

Soon, I received two more messages claiming to be from PayPal and impressing upon me of the safety of the transaction:

"My name is Mellisa and it is my pleasure to assist you in regards to the transaction between you and Rick Smith. We cannot credit your account until you send us the transfer details, but I am very happy to be assigned to tell you that the transaction is 100% secure and legitimate, we want to use this medium to tell you once again that the amount of $1,680.00 USD has been made to your account by Rick Smith."

The email stated that if I had any concerns, I should express them by responding to the message. The email software would make the victim believe that such queries would go to Service@PayPal.com, while in reality they would be directed to Email.transactionverifier@consultant.com.

"Go to any Money Gram Outlet close to your home"

According to fake PayPal's emails, I had to take one last step to complete the transaction: I had to send money via Money Gram to the buyer's agent, who would be responsible for picking up the purchased item from my location. This step was explained in multiple emails, including the one from the supposed buyer, Rick Smith, which came from ric.smith222@gmail.com:

"I want you to know that i added an extra fee of $680 to the total payment which i need you to help send to the agent coming for pick up and it needs to be sent via Money Gram as that's the only way they can get it. I am sorry i should have informed you but i only got the urgent message from the pick up agent that they will need the funds before they can come to pick up when i was about making the payment. [...] I also added $100 the Money Gram charges."

One of the messages specified the name of the person who would pick up the money in Bangor, PA in the US. In the context of this scam, this person was acting as a money mule.

Though my emails to the fake PayPal account Email.transactionverifier@consultant.com went unanswered, the scammer did respond from ric.smith222@gmail.com when I asked why he couldn't pay the pick-up agent directly:

"There is no money gram here to make the transfer and I tried more that 4 times making the transfer online but they keep on rejecting my card."

So, to receive payment for the item I was selling, I had to first send irrevocable funds to someone in Pennsylvania. In this case, the scammer requested funds via MoneyGram. Other variations of the scam that I've seen asked the victim to transfer funds using Western Union. Supposedly the money I would receive via PayPal would reimburse me for that expense.

"Surf anonymously"

Curious whether I could gather any information about the scammer, I emailed him (or her) a link to a benign image that resided on my temporary web server. In my email message to the scammer I asked for help making sense of MoneyGram's website and provided a URL to the screenshot. The scammer initially told me to visit MoneyGram in person, but after I threatened to give up on the transaction, I saw someone retrieving the image from my server:

GET /images/screenshot15.jpg HTTP/1.1
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8

If these headers are to be believed, the scammer was using an up-to-date version of Google Chrome on Windows 7.

The connection came from This IP is on a /24 subnet assigned to Kaia Global Networks in the US, on the Sprint network according to Robtex. One Wikipedia page I found indicated that this subnet hosted CyberGhost VPN exit nodes. I downloaded this provider's VPN client and was able to confirm that is, indeed, one of the IPs associated with the paid version of the service.

Alas, the scammer was careful to obscure his origins by tunneling through the this Romania-based VPN service, which is designed "protect your online privacy, surf anonymously and access blocked or censored content." According to my testing, CyberGhost's VPN doesn't modify browser headers, though the scammer could have tweaked them using other means.

"The nature of my work"

I searched the web for the artifacts exhibited by the scammer in the interactions above to assess the scope of the malevolent activities. I found a few complaints associated with the two phone numbers. They dated to 2014, possibly because these VoIP numbers were misused for other shady machinations (1, 2, 3) at the time. I saw no mention of ric.smith222@gmail.com, though joylove270@gmail.com was associated with several complaints that began in April 2014 and matched the pattern of this scam. At the time, "Rick Smith" was using other phone numbers, including 610-455-5663 and 914-268-3815.

When I pivoted my search on "Rick Smith," I came across numerous reports (1, 2, 3, 4) from Craigslist sellers who were targeted in the manner described above. The phone numbers in these complaints were too numerous to list here. The reports mentioned other names and email addresses employed in the scam, including: brwnsmit10@gmail.com, Anthony Smith, walkerchromer@gmail.com, Richard Johnson, walkerchromer@gmail.com, p.poner12301@gmail.com, safareewalker@gmail.com, walkingthon@gmail.com, celisiur@gmail.com, richardjrbrown09@gmail.com, brwnsmit6@gmail.com, celisiur477@gmail.com, rick06smith@gmail.com, lamdons4@gmail.com, Frank Rick, customerhelpline@mail2pay.com, andie.macdowell099@gmail.com, pallybill@gmail.com, etc.

The scammer's pickup agentsmoney mules mentioned in the discussion forums above included: Levon Rivers, Columbus, OH 43227; David. Jacobo, Federal Way, WA 98003; Rob Frazier, Brooklyn, NY 11212; Terry Dunn, Lebanon, OH 45036; and Billy Ray Mayo, Livingston, LA 70754.

The earliest mention of the activities I observed and attributed to this scammer date to January 2012. At the time, the scammer used the email address brwnsmith20@gmail.com—the same address included in the body of the fake PayPal notification email that I received. The scammer's target wrote that the scammer claimed to be on active duty in the military, using that excuse to explain why he could not speak on the phone or pick up the item in person. The scammer reportedly stated, "Am not available to talk through phone due to the nature of my work."

This set of scams might be the work of a single miscreant. It's also possible that a group of scammers is using a common toolkit to prey on Craigslist sellers. Regardless, I'm disheartened to see the volume of complaints associated with these activities. The person or people behind them seem to be operating with apparent impunity for years. Perhaps some of the details above can assist law enforcement with weaving these malicious actions into a pattern that helps identify the individual(s) responsible for them.

In a variation of the overpayment scheme, the fake buyer promised me to mail a money order to purchase the item, then claimed that "the secretary made mistake of over payment, she has been sacked." The scammer asked, "Can i count on you to send my difference back"? In this case, the money order will eventually bounce, but before the victim refunds the "overpaid" funds to the scammer.
My wife has had multiple of these when attempting to sell a vehicle on autotrader.ca last summer. Paypal was again used as the hook, with MoneyGram the route to send them cash. The only difference was that the extra balance was allegedly for paying the shipper who would be inspecting and picking up the vehicle. Paypal has a spoof-checking email you can forward to to confirm the validity of a suspicious email (spoof@paypal.com), which confirmed these as fakes.
> the scammer was establishing a reason why he could interact with me using voice calls.

Could, or could not?

By the way, in the last month, I have been recruited as a "money-mule", i.e., "receive payments, keep 10%, and then disburse (or more likely 'disperse') the remaining 90%". I have received two cheques (one about $9000 and one about $49000) that passed all the anti-counterfeiting checks:
* micro-printing on borders
* water-marks
* embedded visible fibers on both front and back
* fibers only visible under "black" light
* temperature-sensitive spot that vanishes under heat (breath or warm fingers)

Quite disconcerting!

I took both cheques to my bank, for their review.

The first cheque turned out to be stolen from the issuing business,
and then filled-in, presumably by the scammer.

The bank-manager noted that the signatures on the second cheque were NOT made by a liquid-ink pen -- they were computer-printed onto the cheque, maybe originating from a scan of a valid cheque.

The company that "lost" the first cheque had NOT "flagged" nor "closed" the account on which the cheque was drawn. Shame on them!

I got a call-back from the second company, but they are still investigating the loss/theft of their cheque.

In summary, I have been dealing with a sophisticated scammer (with a telephone-number in the Far East) who seems to have cohorts in two different Canadian provinces (judging from the cancellation-marks on the envelopes), and who seems to have access to stolen blank-cheques.
