Over the past six months, I've had unprecedented access to a scam call centre.
2
YouTube's policies have meant that I've had to blur certain sections of this video, but if you're a patron of mine, you can access the full uncensored version through Patreon.
3
This video gives a unique view of how these scams operate and who these scammers really are.
4
Critical alert from Michael Shirt.
5
You're looking at the webcam of a scammer named Deva War...
6
He is currently uploading phone numbers of people who will be his next potential victims.
7
All of the phone numbers are from people who have previously fallen victim to a pop-up scam, as you can see here.
8
Knowing that these people are already victims is particularly useful to this group of scammers because they operate a refund scam.
9
They'll pretend to be a real computer company and make calls like this.
10
Hi, we are calling you from Microsoft Refund Department.
11
If you remember,
12
you have a contract with us for computer support and services unfortunately we are closing the business so
13
you can give us a call for the refund of the amount you paid to claim your refund please
14
call us on 877 281 1024 the way that deva and the rest of the people in this call center get their leads is via WhatsApp or directly by email.
15
Here you can see him using WhatsApp to download a spreadsheet of the most recent victims.
16
When he has the list of numbers, he will then look at it in a spreadsheet to make sure that it will go into the outbound calling software.
17
He will remove any duplicates before starting a campaign.
18
Here they've been emailed a fresh list of numbers.
19
Once they've downloaded this list, they will start up their VoIP software.
20
Here they're using voxaccount.com.
21
And that's a legitimate piece of software which will allow them to make lots of outbound calls.
22
They will charge up their Vox account with about $100 every few days, and the eight or so agents will sit and wait for inbound calls.
23
Here you can see the rate of these calls.
24
The icons at the bottom represent agents who are ready to receive calls, and they're in green.
25
And anyone actively engaged in the call is coloured amber.
26
So let's go for a little office tour whenever one of these outbound campaigns are in action.
27
As you can see, the offices are very small and cramped, and each agent has only a very basic PC on his desk.
28
They don't use phones and instead use VoIP software.
29
They will use Xlight for their inbound calls and 3CX for the outbound ones.
30
A lot of these scammers smoke, so you can imagine the smell in this place.
31
But this particular PC is a laptop so it can be carried around the office.
32
So courtesy of this particular scammer we're going to get a little tour of exactly what the office looks like.
33
Listen carefully to the scams going on in the background.
34
There is an option.
35
You see that?
36
Blackua.
37
Click on that option.
38
Download.
39
Blackua.
40
Hello?
41
Hello?
42
I have to click on download.
43
What's come up?
44
Yes.
45
Then P as in Peter.
46
Right, scroll it down the page.
47
In a minute.
48
I am showing you team weaver format.
49
Do you see that?
50
There is a black flag like the outside.
51
Then P is in Peter.
52
Okay, scroll down the page.
53
Now it's back up on your screen.
54
A little bit.
55
I'm going to Peter.
56
I'm back in office.
57
Hold on, hold on.
58
I'm showing you Team Beaver format.
59
Do you see that?
60
There's a black flag on the left here.
61
Now, sir, have a look on the black box and...
62
What do you see now?
63
...the receiver lane, receiver band...
64
Now, underneath the Team Beaver format is a nuclear box download now.
65
There's on that.
66
Alright, sir.
67
Because see, I can't see this screen right now.
68
And after click on it, ma'am, I'm a little bit right inside on the very top of your computer screen, beside the address bar.
69
There is any blue-color or black-color down arrow.
70
Click on that arrow.
71
Er ch harm her
72
not infra Yours So as you can see they are quite small offices, one of the smallest groups of scammers I've encountered.
73
But equally you can also appreciate that this laptop is on a wireless network and it's that wireless network that gives me a good clue as to exactly where these offices are located.
74
I already knew from the IP address what the approximate location was, they're in Calcutta or Kolkata in India.
75
But to pinpoint their location it's possible to use additional information and I get this from their wireless access information.
76
On screen you can see a list of wireless networks.
77
This PC has connected to those wireless networks and some of them are even active now.
78
Together with the signal strength and using some Google map data it's possible to pinpoint their location within 150 metres.
79
So these scammers are close to the centre of Kolkata, to the east of the river and very near the Rippon Residency.
80
I needed to be as accurate as I could with their location because I wanted to report them to the cyber police in Kolkata.
81
I couldn't give them a business address because they're not a business, they just all know each other.
82
So I also wanted to figure out their various names, but I could only do this by listening to some audio, so I listened and watched their scams over the next few weeks and months.
83
I was particularly keen to identify this group because they did some of the most awful things that I've seen any group do before.
84
The person on screen is called Christy.
85
They offered her a refund, but instead they turned on her webcam, threatened her, grabbed pictures of her children, and ultimately tried to delete all of her files.
86
If you haven't seen this video, there's a link to it in the description below.
87
So over the next few weeks, I observed this team running the refund scam.
88
Here they are editing HTML to make it look as if they've transferred money to the victim and will want the money back of course.
89
They describe themselves as NTS IT Care.
90
These are another scamming organisation in Kolkata where they get most of their data from.
91
But there's a rule that I'm going to let you know.
92
But before going to let you know, I do believe you can see your computer screen.
93
And if you can see your computer screen ma'am.
94
So first of all do me a favour, simply sign out from your bank account madam.
95
The refund scam works by the scammer persuading the victim to log into their bank account.
96
He will have promised a certain amount but he'll edit the screen so it looks as if too much has been put in.
97
He will then ask the victim to return the money through a bank transfer or more likely these days some sort of gift card.
98
When you're going to your bank right again to sending that money exactly so you don't need to tell your bank people that hey I have transferred that money on the first time the money gets cancelled and that's why I ask.
99
You can watch him on this webcam coaching the victim what to say when she goes into the bank.
100
my god might be i don't know because i live in california you know so by okay suppose if the same people okay
101
tell them hey i want to transfer that money when you tell them that might be they can open your bank account and check that all right but they will not ask you this thing that hey these monies get cancelled because the reason we
102
of course but you can tell them hey i want to transfer again to him because it's required all right second time i do
103
just see on the second no they will not ask you this money get back to you or whatever because the reason we are hiding these things from your bank you bank people they will not able to see that the money get cancelled i'm telling you that all right
104
The refund scam usually requires the victim not to speak to anyone in the bank and this particular scammer has persuaded her that the bank are in on a scam and not to mention any details to anyone in the bank.
105
now just no they can't see that because just see we just see your bank and my bank are connected each
106
other so i had shown you this thing that hey ma'am this has happened but in the computer your bank computer screen will be
107
not sure that the money get cantilever just shows that 29 250 dollar has been created but this thing it will be not shows
108
that money get cancelled understand i'm telling you that because i'm the man of my word and at the same time your bank and my bank they are connected
109
to each other and i will not give the permissions to your bank as well that they can look that the money get cancelled
110
and that's why you come here okay i'm telling you that all this time i was quietly observing their scams in action and i didn't let any of the victims that i observed fall victim to any of the scams.
111
But I did want to disrupt them as much as I possibly could.
112
So when I observed them making contact with a company called Dialer360.com in order to set up a new outbound campaign, I saw an opportunity.
113
What they do is send an outbound message to potential victims about a refund, and this was my opportunity to substitute the audio.
114
Interestingly, I also observed that Dialer 360 were completely complicit in the scam that was going on.
115
In fact, they even wanted the audio which would be played to the victims.
116
They didn't have the expertise themselves, so they drafted in an expert called Hazran who set up Dialer 360 so that this group of scammers were set up correctly to scam the maximum number of victims.
117
Dialer360 didn't exactly care who was buying their software and whenever they asked for a scanned ID card the reply was why no one's ever asked for that before and that seemed perfectly acceptable to Dialer360.
118
They allocated the direct international dial or DID number regardless.
119
So I thought carefully about the best way to disrupt this new campaign.
120
Obviously I couldn't stop them getting new numbers, but what I could do is hopefully get a warning to their potential victims.
121
So I thought I would substitute the audio.
122
This is what their original audio sounded like.
123
Hi, we are calling you from Microsoft Refund Department.
124
If you remember, you have a contract with us for computer support and services.
125
Unfortunately, we are closing the business.
126
So you can give us a call for the refund of the amount you paid to claim your refund.
127
Please call us on 747-212-9887.
128
I repeat 747-212-9887 or press 1 to talk with our executive.
129
Thank you.
130
And I decided to replace it with this.
131
Hello, this is an automated message being sent from scammers from India.
132
They were going to try to scam you by claiming that you would get a refund from your computer maintenance company.
133
However, this is just a scam so that they can access your computer and will try to get money from your bank account.
134
If you ever get a message like this, it is always a scam.
135
Please do not mention that I have changed their message, but if you would like to waste their time, you can speak to these scammers by pressing one on your telephone keypad.
136
And as it turned out, this was the most effective way of getting a message to some of their potential victims.
137
all at the expense of the people making the calls, the scammers themselves.
138
Not only did I keep substituting the audio and only replacing it whenever they were asking for a bit of help from Dialer 360 but I also increased the rate of these calls to drain their money as quickly as I possibly could.
139
Although this footage is sped up, I watched overnight as I drained all of their money.
140
The total consumption is the cost in dollars.
141
and every cent which is being consumed means a message is getting to one of their prospective victims.
142
All very satisfying.
143
And all this time they couldn't work out why they weren't getting the expected volume of calls.
144
From their chat logs it was quite obvious to them that they were having some sort of problem but couldn't pinpoint it.
145
Eventually when I drained all of their money over several weeks they figured out there must have been some sort of compromise and finally they twigged that there was something going on with their audio.
146
But I still had very blurry photographs through a webcam of the people involved so I was thrilled whenever Deva uploaded his wedding photographs to the internet and I was able to get a lot clearer pictures of his workmates.
147
So although I don't know who's who here I do know there's an Amit, there's a Rizwan, there's a TUSIF and there's a Waseem.
148
I did email the Kolkata Cyber Police in the hope that they would do something.
149
I sent them a link to the unblurred version of this video but I've had absolutely nothing back from them.
150
I can only assume they're not going to do anything.
151
Therefore I'm left with posting this to YouTube and you'll also find a link in the description to the unblurred version which is on d.tube.
152
If I hear back from the police I'll be sure to post an update but the first people who get to know are my patrons and I thank them for sponsoring me.
153
If you wish to become a patron, there's a link here and I'm also on Twitter at JimBrowning11.
154
Again, thank you for watching.

このビデオで話す練習をする理由は？
このビデオは、詐欺コールセンターの実態を直に見ることができる貴重な内容を提供しています。詐欺師がどのようにしてターゲットを見つけ、電話をかけてくるのかを学ぶことで、英語を使ったコミュニケーションの実際の状況を理解する手助けになります。特に、電話での会話は日常生活や仕事でよくあるシーンですので、リアルな英語スピーキング練習として最適です。このビデオを使って、英語スピーキング練習を行うことで、実際のコールが持つリズムやトーンに慣れることができます。また、詐欺師たちが使用する表現を真似することで、シャドーイング技術を高めることも可能です。
文法と表現の文脈
このビデオでは、いくつかの重要な構造や表現が使用されています。以下にその例を挙げます：
- 疑問文の使用：「Hi, we are calling you from Microsoft Refund Department.」この構造は、電話の開始時に非常に一般的です。
- 条件文：「If you remember, you have a contract with us...」この文は、記憶を引き出すための効果的な方法であり、相手に安心感を与えます。
- 命令形：「please call us on 877 281 1024」このような表現は、受け手に具体的な行動を促す時に使われます。
これらの表現をshadow speechとして練習することで、自然な会話能力が向上します。
一般的な発音の罠
このビデオには、特に注意が必要な言葉やアクセントがあります：
- 「refund」：この単語は、発音時に力を入れるスyllableが異なる場合があります。特に「リファンド」と「リファンド」の違いを意識しましょう。
- 「contract」：この単語の発音において、非常に速い会話の中で「コン」の部分が弱まることがあります。
- 「department」：この単語は、一般的にこのような文脈でよく使用されるため、スムーズに発音できるように練習しましょう。
これらに注意しながら、英語シャドーイングを行うことで、より流暢な英会話が身につきます。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
