All About Call Spoofing

Real call spoofing requires serious infrastructure and technical knowledge - not that TextNow app bullshit or Telegram ripper garbage that floods your DMs. Those dipshits selling "private number" services wouldnt know proper spoofing if it slapped them in their face.

This guide breaks down call spoofing from basic concepts to advanced exploitation. No flashy promises, no magic apps - just the hard technical knowledge that lets you bypass modern call detection systems.

Big Money Still Flows Through Voice

Phone systems still drive billions in sales across major retailers. Companies like Victorias Secret, Nordstrom and countless others actively push customers to order by phone. Why? Because old people are retarded when it comes to technology. As to why your granma needs Victoria Secret lingerie, thats a mystery for another day.

But even without direct phone carding, voice spoofing unlocks a trove of opportunities:

Balance checking at scale

Mass OTP interception

Bank account takeover

Order rerouting/address changes

Refund fraud at scale

Corporate account compromise

Customer service social engineering

The financial sector especially runs on voice. Those phone reps get trained to "help customers" work around security measures, creating perfect social engineering opportunities. One clean spoofed call can accomplish more than days of failed web-based attempts.

The Technical Stack

View attachment 6350

Modern phone systems are a beautiful clusterfuck of old and new tech mashed together. Understanding this mess matters because most fraud prevention still relies on legacy systems that barely changed since the 90s.

Three levels of spoofing exist in this ecosystem:

Basic ID Spoofing: What those garbage apps do. Just changes the displayed number without touching underlying call data. Fine for pranking your friends, useless for anything serious.

Carrier-Level Spoofing: Routes calls through legitimate telcos, making them appear as normal PSTN traffic. Expensive as fuck but nearly impossible to detect. Required for serious bank operations.

Full SIP Spoofing: The sweet spot for most carders. Controls the entire call chain and mimics legitimate traffic patterns. Needs proper infrastructure but can bypass most detection systems.

The Building Blocks

Three main types of phone systems matter for us:

PSTN (Public Switched Telephone Network)
The granddaddy of them all. This traditional phone network still connects landlines worldwide. Banks, credit card companies and big corporations use PSTN because its reliable as fuck. When you call Chase or Amex, youre probably hitting their PSTN lines.

For carders, PSTN matters because:

Most financial institutions trust PSTN calls more than VoIP

Caller ID spoofing detection barely exists

Crystal clear audio quality (crucial for social engineering)

Less recording/monitoring compared to VoIP

VoIP (Voice over IP)
Voice transmitted over internet protocol - basically turning voice into data packets. Think Skype or your sketchy calling app. Most modern business phone systems use VoIP because its cheap and flexible.

VoIP advantages for fraud:

Easy to mask origin location

Dirt cheap international calls

Simple operation scaling

Multiple numbers on one system

Advanced call routing options

SIP (Session Initiation Protocol)
The protocol that makes VoIP work. SIP handles all the setup, teardown and control of VoIP calls. Think of it like HTTP but for voice communication. Most importantly, SIP lets us build our own private phone infrastructure.

Why SIP rocks for carders:

Complete control over caller ID presentation

Route calls through multiple servers

Mix with VPNs for extra anonymity

Build private phone networks

No central provider to snitch

Typical call flow looks like this:
View attachment 6351

Code:

Your Device -> SIP Server -> VoIP Provider -> PSTN Gateway -> Target Phone

Each hop in this chain affects how receiving systems see your calls. Banks dont just check the phone number - they analyze the entire call signature as it passes through this infrastructure.

This is why running your own SIP setup matters. Those "private number" services might work for pizza orders but anything touching financial systems needs proper infrastructure.

The Reality of Caller ID

View attachment 6352

Banks and financial institutions validate incoming calls through multiple layers of checks that cheap spoofers cant bypass. When a call hits their system, they check:

The presented caller ID number

Where the call originated from

Which carriers handled the routing

Call signaling patterns and metadata

Historical usage patterns

This is why your TextNow calls get blocked instantly. The numbers might look legit but the underlying signature screams VoIP fraud.

With SIP you control the entire call chain. Your calls can mimic legitimate PSTN traffic passing through trusted carriers. The secret lies in understanding how different financial institutions validate incoming numbers.

Some banks only check basic caller ID. These are your easy targets - basic number spoofing works fine. Others dig deeper, looking at call routing and carrier signatures. These need proper SIP infrastructure to appear legitimate.

The most sophisticated systems analyze call patterns over time. They track how often numbers hit their system, which carriers route them, and typical usage patterns.

Building Your Own Setup

Here are two methods that actually work without needing a PhD in telecommunications:

Method 1: Carded SIP Trunk

Easiest method that still gets results. Card Twilio, Telnyx or voip.ms. These work fine for most sites.

Requirements:

Clean card with solid antidetect setup

Business email (not free email)

MicroSIP (free softphone)

Residential proxy

Steps:
View attachment 6353

Card a Telnyx Account (or other SIP providers):

Sign up for an account with Telnyx or your preferred SIP provider.

Buy a DID Number:

Purchase a DID number that matches your target area for local calls.

Grab Credentials from the Dashboard:

Log in to your Telnyx dashboard and navigate to the section where you can find your SIP credentials (username, password, and SIP server details).

Change the Caller ID:

In your Telnyx account, look for the option to set a Caller ID Override. This allows you to specify the caller ID you want to display when making outbound calls.

Configure MicroSIP:

Open MicroSIP and go to Account > Add to create a new SIP account.

Enter the following details:

Domain:

Code:

sip.telnyx.com

(or the SIP server address provided by your provider).

Username: Your SIP username from the Telnyx dashboard.

Password: Your SIP password from the Telnyx dashboard.

Transport: Select TCP.

Set Local Number as Your DID: Enter your purchased DID number in the appropriate field.

Save the Configuration:

Click OK to save the account settings in MicroSIP.

Test the Setup:

Make an outbound call using MicroSIP to ensure that the caller ID is displayed as specified and that the call connects successfully.

Method 2: DIY FreePBX

More setup work but better for bank related fraud. Harder to detect since you control the whole system.
View attachment 6354
Requirements:

Carded VPS (OVH or DigitalOcean work fine)

FreePBX ISO

DID number from any provider (some are more accomodating to spoofing, so do your own research)

MicroSIP

Same proxy setup as Method 1

Steps:

Card a VPS:

Choose a VPS provider and set up your server.

Download and Install FreePBX:

Follow the installation instructions for FreePBX on your VPS.

Basic Configuration in Admin Panel:

Add Extensions:

Go to Applications > Extensions and create the necessary extensions.

Set Outbound Routes:

Navigate to Connectivity > Outbound Routes and configure your outbound routes.

In the outbound route settings, find the CID Options to set the default caller ID you want to use for outbound calls.

Configure Your DIDs:

Go to Connectivity > Inbound Routes and set up any Direct Inward Dialing (DID) numbers you have.

Set Caller ID Spoofing:

In the Outbound Routes, specify the caller ID you want to use in the Caller ID field (make sure you have the right to use this number).

Ensure your trunk settings allow for caller ID manipulation.

Point MicroSIP to Your VPS IP:

Download and install MicroSIP on your local machine.

Open MicroSIP and go to Account > Add to create a new SIP account.

Enter the following:

Display Name: Name for the account.

SIP Server: Your VPSs IP address or domain name.

SIP Username: The extension number you created.

SIP Password: The password associated with that extension.

STUN Server (optional): Use a STUN server if needed for NAT.

Save the Configuration in MicroSIP:

Click OK to save the account settings.

Test the Connection:

Make a test call to ensure that the spoofed caller ID is displayed correctly and that the call goes through successfully.

Both methods work but remember these core rules:

* Hidden text: cannot be quoted. *

Running your own PBX server will give you more consistency, since these SIP providers are iffy and tend to disable accounts they suspect of malicious activities from time to time. However, if youre just starting, stick with Method 1. Its simpler and good enough for most shit. Only bother with FreePBX if youre doing heavy bank fraud or need total control over your infrastructure.

Conclusion

Call spoofing isn't some magic trick - it's a technical skill that requires serious know-how and infrastructure. If you're still thinking about using some bullshit app or Telegram service, you're missing the point entirely.

Understanding the tech stack is crucial, and DIY setups give you more control and consistency. This guide isn't for wannabes or script kiddies. It's for those ready to put in the work and be better at fraud.

Master these techniques, and you'll open doors that most "carders" can only dream about. Just don't come crying when you fuck up and get caught. This shit's not a game. Stay sharp, stay cautious, and always be learning. The phone system's a mess, and that's your advantage - if you're smart enough to use it. d0ctrine out.

View attachment 6354
Requirements:

Carded VPS (OVH or DigitalOcean work fine)

FreePBX ISO

DID number from any provider (some are more accomodating to spoofing, so do your own research)

MicroSIP

Same proxy setup as Method 1

Steps:

Card a VPS:

Choose a VPS provider and set up your server.

Download and Install FreePBX:

Follow the installation instructions for FreePBX on your VPS.

Basic Configuration in Admin Panel:

Add Extensions:

Go to Applications > Extensions and create the necessary extensions.

Set Outbound Routes:

Navigate to Connectivity > Outbound Routes and configure your outbound routes.

In the outbound route settings, find the CID Options to set the default caller ID you want to use for outbound calls.

Configure Your DIDs:

Go to Connectivity > Inbound Routes and set up any Direct Inward Dialing (DID) numbers you have.

Set Caller ID Spoofing:

In the Outbound Routes, specify the caller ID you want to use in the Caller ID field (make sure you have the right to use this number).

Ensure your trunk settings allow for caller ID manipulation.

Point MicroSIP to Your VPS IP:

Download and install MicroSIP on your local machine.

Open MicroSIP and go to Account > Add to create a new SIP account.

Enter the following:

Display Name: Name for the account.

SIP Server: Your VPSs IP address or domain name.

SIP Username: The extension number you created.

SIP Password: The password associated with that extension.

STUN Server (optional): Use a STUN server if needed for NAT.

Save the Configuration in MicroSIP:

Click OK to save the account settings.

Test the Connection:

Make a test call to ensure that the spoofed caller ID is displayed correctly and that the call goes through successfully.

Both methods work but remember these core rules:

* Hidden text: cannot be quoted. *

Running your own PBX server will give you more consistency, since these SIP providers are iffy and tend to disable accounts they suspect of malicious activities from time to time. However, if youre just starting, stick with Method 1. Its simpler and good enough for most shit. Only bother with FreePBX if youre doing heavy bank fraud or need total control over your infrastructure.

Conclusion

Call spoofing isn't some magic trick - it's a technical skill that requires serious know-how and infrastructure. If you're still thinking about using some bullshit app or Telegram service, you're missing the point entirely.

Understanding the tech stack is crucial, and DIY setups give you more control and consistency. This guide isn't for wannabes or script kiddies. It's for those ready to put in the work and be better at fraud.

Master these techniques, and you'll open doors that most "carders" can only dream about. Just don't come crying when you fuck up and get caught. This shit's not a game. Stay sharp, stay cautious, and always be learning. The phone system's a mess, and that's your advantage - if you're smart enough to use it. d0ctrine out.

All About Call Spoofing

Real call spoofing requires serious infrastructure and technical knowledge - not that TextNow app bullshit or Telegram ripper garbage that floods your DMs. Those dipshits selling "private number" services wouldnt know proper spoofing if it slapped them in their face.

View attachment 6349

This guide breaks down call spoofing from basic concepts to advanced exploitation. No flashy promises, no magic apps - just the hard technical knowledge that lets you bypass modern call detection systems.

Big Money Still Flows Through Voice

Phone systems still drive billions in sales across major retailers. Companies like Victorias Secret, Nordstrom and countless others actively push customers to order by phone. Why? Because old people are retarded when it comes to technology. As to why your granma needs Victoria Secret lingerie, thats a mystery for another day.

But even without direct phone carding, voice spoofing unlocks a trove of opportunities:

Balance checking at scale

Mass OTP interception

Bank account takeover

Order rerouting/address changes

Refund fraud at scale

Corporate account compromise

Customer service social engineering

The financial sector especially runs on voice. Those phone reps get trained to "help customers" work around security measures, creating perfect social engineering opportunities. One clean spoofed call can accomplish more than days of failed web-based attempts.

The Technical Stack

View attachment 6350

Modern phone systems are a beautiful clusterfuck of old and new tech mashed together. Understanding this mess matters because most fraud prevention still relies on legacy systems that barely changed since the 90s.

Three levels of spoofing exist in this ecosystem:

Basic ID Spoofing: What those garbage apps do. Just changes the displayed number without touching underlying call data. Fine for pranking your friends, useless for anything serious.

Carrier-Level Spoofing: Routes calls through legitimate telcos, making them appear as normal PSTN traffic. Expensive as fuck but nearly impossible to detect. Required for serious bank operations.

Full SIP Spoofing: The sweet spot for most carders. Controls the entire call chain and mimics legitimate traffic patterns. Needs proper infrastructure but can bypass most detection systems.

The Building Blocks

Three main types of phone systems matter for us:

PSTN (Public Switched Telephone Network)
The granddaddy of them all. This traditional phone network still connects landlines worldwide. Banks, credit card companies and big corporations use PSTN because its reliable as fuck. When you call Chase or Amex, youre probably hitting their PSTN lines.

For carders, PSTN matters because:

Most financial institutions trust PSTN calls more than VoIP

Caller ID spoofing detection barely exists

Crystal clear audio quality (crucial for social engineering)

Less recording/monitoring compared to VoIP

VoIP (Voice over IP)
Voice transmitted over internet protocol - basically turning voice into data packets. Think Skype or your sketchy calling app. Most modern business phone systems use VoIP because its cheap and flexible.

VoIP advantages for fraud:

Easy to mask origin location

Dirt cheap international calls

Simple operation scaling

Multiple numbers on one system

Advanced call routing options

SIP (Session Initiation Protocol)
The protocol that makes VoIP work. SIP handles all the setup, teardown and control of VoIP calls. Think of it like HTTP but for voice communication. Most importantly, SIP lets us build our own private phone infrastructure.

Why SIP rocks for carders:

Complete control over caller ID presentation

Route calls through multiple servers

Mix with VPNs for extra anonymity

Build private phone networks

No central provider to snitch

Typical call flow looks like this:
View attachment 6351

Code:

Your Device -> SIP Server -> VoIP Provider -> PSTN Gateway -> Target Phone

Each hop in this chain affects how receiving systems see your calls. Banks dont just check the phone number - they analyze the entire call signature as it passes through this infrastructure.

This is why running your own SIP setup matters. Those "private number" services might work for pizza orders but anything touching financial systems needs proper infrastructure.

The Reality of Caller ID

View attachment 6352

Banks and financial institutions validate incoming calls through multiple layers of checks that cheap spoofers cant bypass. When a call hits their system, they check:

The presented caller ID number

Where the call originated from

Which carriers handled the routing

Call signaling patterns and metadata

Historical usage patterns

This is why your TextNow calls get blocked instantly. The numbers might look legit but the underlying signature screams VoIP fraud.

With SIP you control the entire call chain. Your calls can mimic legitimate PSTN traffic passing through trusted carriers. The secret lies in understanding how different financial institutions validate incoming numbers.

Some banks only check basic caller ID. These are your easy targets - basic number spoofing works fine. Others dig deeper, looking at call routing and carrier signatures. These need proper SIP infrastructure to appear legitimate.

The most sophisticated systems analyze call patterns over time. They track how often numbers hit their system, which carriers route them, and typical usage patterns.

Building Your Own Setup

Here are two methods that actually work without needing a PhD in telecommunications:

Method 1: Carded SIP Trunk

Easiest method that still gets results. Card Twilio, Telnyx or voip.ms. These work fine for most sites.

Requirements:

Clean card with solid antidetect setup

Business email (not free email)

MicroSIP (free softphone)

Residential proxy

Because old people are retarded when it comes to technology. As to why your granma needs Victoria Secret lingerie, thats a mystery for another day.

But even without direct phone carding, voice spoofing unlocks a trove of opportunities:

Balance checking at scale

Mass OTP interception

Bank account takeover

Order rerouting/address changes

Refund fraud at scale

Corporate account compromise

Customer service social engineering

The financial sector especially runs on voice. Those phone reps get trained to "help customers" work around security measures, creating perfect social engineering opportunities. One clean spoofed call can accomplish more than days of failed web-based attempts.

The Technical Stack

View attachment 6350

Modern phone systems are a beautiful clusterfuck of old and new tech mashed together. Understanding this mess matters because most fraud prevention still relies on legacy systems that barely changed since the 90s.

Three levels of spoofing exist in this ecosystem:

Basic ID Spoofing: What those garbage apps do. Just changes the displayed number without touching underlying call data. Fine for pranking your friends, useless for anything serious.

Carrier-Level Spoofing: Routes calls through legitimate telcos, making them appear as normal PSTN traffic. Expensive as fuck but nearly impossible to detect. Required for serious bank operations.

Full SIP Spoofing: The sweet spot for most carders. Controls the entire call chain and mimics legitimate traffic patterns. Needs proper infrastructure but can bypass most detection systems.

The Building Blocks

Three main types of phone systems matter for us:

PSTN (Public Switched Telephone Network)
The granddaddy of them all. This traditional phone network still connects landlines worldwide. Banks, credit card companies and big corporations use PSTN because its reliable as fuck. When you call Chase or Amex, youre probably hitting their PSTN lines.

For carders, PSTN matters because:

Most financial institutions trust PSTN calls more than VoIP

Caller ID spoofing detection barely exists

Crystal clear audio quality (crucial for social engineering)

Less recording/monitoring compared to VoIP

VoIP (Voice over IP)
Voice transmitted over internet protocol - basically turning voice into data packets. Think Skype or your sketchy calling app. Most modern business phone systems use VoIP because its cheap and flexible.

VoIP advantages for fraud:

Easy to mask origin location

Dirt cheap international calls

Simple operation scaling

Multiple numbers on one system

Advanced call routing options

SIP (Session Initiation Protocol)
The protocol that makes VoIP work. SIP handles all the setup, teardown and control of VoIP calls. Think of it like HTTP but for voice communication. Most importantly, SIP lets us build our own private phone infrastructure.

Why SIP rocks for carders:

Complete control over caller ID presentation

Route calls through multiple servers

Mix with VPNs for extra anonymity

Build private phone networks

No central provider to snitch

Typical call flow looks like this:

Code:

Your Device -> SIP Server -> VoIP Provider -> PSTN Gateway -> Target Phone

Each hop in this chain affects how receiving systems see your calls. Banks dont just check the phone number - they analyze the entire call signature as it passes through this infrastructure.

This is why running your own SIP setup matters. Those "private number" services might work for pizza orders but anything touching financial systems needs proper infrastructure.

The Reality of Caller ID

View attachment 6352

Banks and financial institutions validate incoming calls through multiple layers of checks that cheap spoofers cant bypass. When a call hits their system, they check:

The presented caller ID number

Where the call originated from

Which carriers handled the routing

Call signaling patterns and metadata

Historical usage patterns

This is why your TextNow calls get blocked instantly. The numbers might look legit but the underlying signature screams VoIP fraud.

With SIP you control the entire call chain. Your calls can mimic legitimate PSTN traffic passing through trusted carriers. The secret lies in understanding how different financial institutions validate incoming numbers.

Some banks only check basic caller ID. These are your easy targets - basic number spoofing works fine. Others dig deeper, looking at call routing and carrier signatures. These need proper SIP infrastructure to appear legitimate.

The most sophisticated systems analyze call patterns over time. They track how often numbers hit their system, which carriers route them, and typical usage patterns.

Building Your Own Setup

Here are two methods that actually work without needing a PhD in telecommunications:

Method 1: Carded SIP Trunk

Easiest method that still gets results. Card Twilio, Telnyx or voip.ms. These work fine for most sites.

Requirements:

Clean card with solid antidetect setup

Business email (not free email)

MicroSIP (free softphone)

Residential proxy

Steps:
View attachment 6353

Card a Telnyx Account (or other SIP providers):

Sign up for an account with Telnyx or your preferred SIP provider.

Buy a DID Number:

Purchase a DID number that matches your target area for local calls.

Grab Credentials from the Dashboard:

Log in to your Telnyx dashboard and navigate to the section where you can find your SIP credentials (username, password, and SIP server details).

Change the Caller ID:

In your Telnyx account, look for the option to set a Caller ID Override. This allows you to specify the caller ID you want to display when making outbound calls.

Configure MicroSIP:

Open MicroSIP and go to Account > Add to create a new SIP account.

Enter the following details:

Domain:

Code:

sip.telnyx.com

(or the SIP server address provided by your provider).

Username: Your SIP username from the Telnyx dashboard.

Password: Your SIP password from the Telnyx dashboard.

Transport: Select TCP.

Set Local Number as Your DID: Enter your purchased DID number in the appropriate field.

Save the Configuration:

Click OK to save the account settings in MicroSIP.

Test the Setup:

Make an outbound call using MicroSIP to ensure that the caller ID is displayed as specified and that the call connects successfully.

Method 2: DIY FreePBX

More setup work but better for bank related fraud. Harder to detect since you control the whole system.
View attachment 6354
Requirements:

Carded VPS (OVH or DigitalOcean work fine)

FreePBX ISO

DID number from any provider (some are more accomodating to spoofing, so do your own research)

MicroSIP

Same proxy setup as Method 1

Steps:

Card a VPS:

Choose a VPS provider and set up your server.

Download and Install FreePBX:

Follow the installation instructions for FreePBX on your VPS.

Basic Configuration in Admin Panel:

Add Extensions:

Go to Applications > Extensions and create the necessary extensions.

Set Outbound Routes:

Navigate to Connectivity > Outbound Routes and configure your outbound routes.

In the outbound route settings, find the CID Options to set the default caller ID you want to use for outbound calls.

Configure Your DIDs:

Go to Connectivity > Inbound Routes and set up any Direct Inward Dialing (DID) numbers you have.

Set Caller ID Spoofing:

In the Outbound Routes, specify the caller ID you want to use in the Caller ID field (make sure you have the right to use this number).

Ensure your trunk settings allow for caller ID manipulation.

Point MicroSIP to Your VPS IP:

Download and install MicroSIP on your local machine.

Open MicroSIP and go to Account > Add to create a new SIP account.

Enter the following:

Display Name: Name for the account.

SIP Server: Your VPSs IP address or domain name.

SIP Username: The extension number you created.

SIP Password: The password associated with that extension.

STUN Server (optional): Use a STUN server if needed for NAT.

Save the Configuration in MicroSIP:

Click OK to save the account settings.

Test the Connection:

Make a test call to ensure that the spoofed caller ID is displayed correctly and that the call goes through successfully.

Both methods work but remember these core rules:

* Hidden text: cannot be quoted. *

Running your own PBX server will give you more consistency, since these SIP providers are iffy and tend to disable accounts they suspect of malicious activities from time to time. However, if youre just starting, stick with Method 1. Its simpler and good enough for most shit. Only bother with FreePBX if youre doing heavy bank fraud or need total control over your infrastructure.

Conclusion

Call spoofing isn't some magic trick - it's a technical skill that requires serious know-how and infrastructure. If you're still thinking about using some bullshit app or Telegram service, you're missing the point entirely.

Understanding the tech stack is crucial, and DIY setups give you more control and consistency. This guide isn't for wannabes or script kiddies. It's for those ready to put in the work and be better at fraud.

Master these techniques, and you'll open doors that most "carders" can only dream about. Just don't come crying when you fuck up and get caught. This shit's not a game. Stay sharp, stay cautious, and always be learning. The phone system's a mess, and that's your advantage - if you're smart enough to use it. d0ctrine out.

Mỗi bước nhảy trong chuỗi này ảnh hưởng đến cách hệ thống tiếp nhận xem cuộc gọi của bạn. Ngân hàng không chỉ kiểm tra số điện thoại - họ phân tích toàn bộ chữ ký cuộc gọi khi nó đi qua cơ sở hạ tầng này.

Đây là lý do tại sao việc chạy thiết lập SIP của riêng bạn lại quan trọng. Các dịch vụ "số riêng" đó có thể hoạt động cho các đơn đặt hàng pizza nhưng bất kỳ thứ gì liên quan đến hệ thống tài chính đều cần cơ sở hạ tầng phù hợp.

Sự thật về ID người gọi

View attachment 6352

Các ngân hàng và tổ chức tài chính xác thực các cuộc gọi đến thông qua nhiều lớp kiểm tra mà những kẻ giả mạo giá rẻ không thể vượt qua. Khi một cuộc gọi đến hệ thống của họ, họ sẽ kiểm tra:

Số ID người gọi được trình bày

Cuộc gọi bắt nguồn từ đâu

Những nhà cung cấp nào xử lý việc định tuyến

Mẫu tín hiệu cuộc gọi và siêu dữ liệu

Mẫu sử dụng lịch sử

Đây là lý do tại sao các cuộc gọi TextNow của bạn bị chặn ngay lập tức. Các số có thể trông hợp lệ nhưng chữ ký bên dưới lại cho thấy đây là gian lận VoIP.

Với SIP, bạn kiểm soát toàn bộ chuỗi cuộc gọi. Các cuộc gọi của bạn có thể mô phỏng lưu lượng PSTN hợp pháp đi qua các nhà mạng đáng tin cậy. Bí quyết nằm ở việc hiểu cách các tổ chức tài chính khác nhau xác thực các số đến.

Một số ngân hàng chỉ kiểm tra ID người gọi cơ bản. Đây là những mục tiêu dễ dàng của bạn - việc giả mạo số cơ bản hoạt động tốt. Những ngân hàng khác đào sâu hơn, xem xét định tuyến cuộc gọi và chữ ký của nhà mạng. Những điều này cần cơ sở hạ tầng SIP phù hợp để có vẻ hợp pháp.

Các hệ thống tinh vi nhất phân tích các mẫu cuộc gọi theo thời gian. Chúng theo dõi tần suất các số đến hệ thống của chúng, nhà mạng nào định tuyến chúng và các mẫu sử dụng thông thường.

Xây dựng thiết lập của riêng bạn

Sau đây là hai phương pháp thực sự hiệu quả mà không cần phải có bằng Tiến sĩ về viễn thông:

Phương pháp 1: Đường dây SIP có thẻ

Phương pháp dễ nhất vẫn mang lại kết quả. Thẻ Twilio , Telnyx hoặc voip.ms. Những phương pháp này hoạt động tốt với hầu hết các trang web.

Yêu cầu:

Thẻ sạch với thiết lập chống phát hiện chắc chắn

Email doanh nghiệp (không phải email miễn phí)

MicroSIP (softphone miễn phí)

Proxy dân cư

Các bước thực hiện:
View attachment 6353

Đăng ký tài khoản Telnyx (hoặc các nhà cung cấp SIP khác):

Đăng ký tài khoản với Telnyx hoặc nhà cung cấp SIP mà bạn ưa thích.

Mua số DID:

Mua số DID phù hợp với khu vực mục tiêu của bạn để gọi điện nội hạt.

Lấy thông tin xác thực từ Bảng điều khiển:

Đăng nhập vào bảng điều khiển Telnyx và điều hướng đến phần nơi bạn có thể tìm thấy thông tin xác thực SIP (tên người dùng, mật khẩu và thông tin chi tiết về máy chủ SIP).

Thay đổi ID người gọi:

Trong tài khoản Telnyx của bạn, hãy tìm tùy chọn để thiết lập Ghi đè ID người gọi . Tùy chọn này cho phép bạn chỉ định ID người gọi mà bạn muốn hiển thị khi thực hiện cuộc gọi đi.

Cấu hình MicroSIP:

Mở MicroSIP và vào Tài khoản > Thêm để tạo tài khoản SIP mới.

Nhập các thông tin sau:

Tên miền:

Code:

sip.telnyx.com

(hoặc địa chỉ máy chủ SIP do nhà cung cấp của bạn cung cấp).

Tên người dùng: Tên người dùng SIP của bạn từ bảng điều khiển Telnyx.

Mật khẩu: Mật khẩu SIP của bạn từ bảng điều khiển Telnyx.

Vận chuyển: Chọn TCP .

Đặt Số địa phương làm DID của bạn: Nhập số DID đã mua vào trường thích hợp.

Lưu cấu hình:

Nhấp vào OK để lưu cài đặt tài khoản trong MicroSIP.

Kiểm tra thiết lập:

Thực hiện cuộc gọi đi bằng MicroSIP để đảm bảo ID người gọi được hiển thị như đã chỉ định và cuộc gọi được kết nối thành công.

Phương pháp 2: Tự làm FreePBX

Nhiều công việc thiết lập hơn nhưng tốt hơn cho gian lận liên quan đến ngân hàng. Khó phát hiện hơn vì bạn kiểm soát toàn bộ hệ thống.
View attachment 6354
Yêu cầu:

VPS có thẻ ( OVH hoặc DigitalOcean hoạt động tốt)

ISO của FreePBX

Số DID từ bất kỳ nhà cung cấp nào (một số nhà cung cấp dễ bị giả mạo hơn, vì vậy hãy tự nghiên cứu)

MicroSIP

Thiết lập proxy giống như Phương pháp 1

Các bước thực hiện:

Thẻ VPS:

Chọn nhà cung cấp VPS và thiết lập máy chủ của bạn.

Tải xuống và cài đặt FreePBX:

Làm theo hướng dẫn cài đặt FreePBX trên VPS của bạn.

Cấu hình cơ bản trong Bảng quản trị:

Thêm tiện ích mở rộng:

Vào Ứng dụng > Tiện ích mở rộng và tạo các tiện ích mở rộng cần thiết.

Thiết lập tuyến đi:

Điều hướng đến Kết nối > Tuyến đi và cấu hình tuyến đi của bạn.

Trong cài đặt tuyến đi, hãy tìm Tùy chọn CID để đặt ID người gọi mặc định mà bạn muốn sử dụng cho các cuộc gọi đi.

Cấu hình DID của bạn:

Vào Kết nối > Tuyến đến và thiết lập bất kỳ số gọi đến trực tiếp (DID) nào bạn có.

Thiết lập giả mạo ID người gọi:

Trong Outbound Routes , hãy chỉ định ID người gọi mà bạn muốn sử dụng trong trường Caller ID (đảm bảo rằng bạn có quyền sử dụng số này).

Đảm bảo cài đặt đường truyền của bạn cho phép thay đổi ID người gọi.

Trỏ MicroSIP tới IP VPS của bạn:

Tải xuống và cài đặt MicroSIP trên máy cục bộ của bạn.

Mở MicroSIP và vào Tài khoản > Thêm để tạo tài khoản SIP mới.

Nhập thông tin sau:

Tên hiển thị: Tên của tài khoản.

Máy chủ SIP: Địa chỉ IP hoặc tên miền VPS của bạn.

Tên người dùng SIP: Số máy nhánh bạn đã tạo.

Mật khẩu SIP: Mật khẩu được liên kết với phần mở rộng đó.

Máy chủ STUN (tùy chọn): Sử dụng máy chủ STUN nếu cần cho NAT.

Lưu cấu hình trong MicroSIP:

Nhấp vào OK để lưu cài đặt tài khoản.

Kiểm tra kết nối:

Thực hiện cuộc gọi thử để đảm bảo rằng ID người gọi giả mạo được hiển thị chính xác và cuộc gọi được thực hiện thành công.

Cả hai phương pháp đều hiệu quả nhưng hãy nhớ những quy tắc cốt lõi sau:

* Văn bản ẩn: không thể trích dẫn. *

Việc chạy máy chủ PBX của riêng bạn sẽ mang lại cho bạn sự nhất quán hơn, vì các nhà cung cấp SIP này không chắc chắn và có xu hướng vô hiệu hóa các tài khoản mà họ nghi ngờ có hoạt động độc hại theo thời gian. Tuy nhiên, nếu bạn mới bắt đầu, hãy sử dụng Phương pháp 1. Nó đơn giản hơn và đủ tốt cho hầu hết mọi thứ. Chỉ bận tâm đến FreePBX nếu bạn đang thực hiện gian lận ngân hàng nghiêm trọng hoặc cần kiểm soát hoàn toàn cơ sở hạ tầng của mình.

Phần kết luận

Việc giả mạo cuộc gọi không phải là trò ảo thuật - đó là một kỹ năng kỹ thuật đòi hỏi kiến thức chuyên môn và cơ sở hạ tầng nghiêm túc. Nếu bạn vẫn đang nghĩ đến việc sử dụng một số ứng dụng nhảm nhí hoặc dịch vụ Telegram, bạn đã bỏ lỡ hoàn toàn mục đích.

Hiểu được công nghệ là rất quan trọng và các thiết lập DIY giúp bạn kiểm soát và nhất quán hơn. Hướng dẫn này không dành cho những người mới vào nghề hoặc những đứa trẻ thích viết kịch bản. Hướng dẫn này dành cho những người sẵn sàng làm việc và giỏi hơn trong việc gian lận.

Nắm vững những kỹ thuật này, và bạn sẽ mở ra những cánh cửa mà hầu hết "người đánh bài" chỉ có thể mơ ước. Chỉ cần đừng khóc lóc khi bạn làm hỏng và bị bắt. Cái này không phải là trò chơi. Hãy luôn cảnh giác, thận trọng và luôn học hỏi. Hệ thống điện thoại đang hỗn loạn, và đó là lợi thế của bạn - nếu bạn đủ thông minh để sử dụng nó. d0ctrine out.
