PayPal Checkout Method
PayPal is fucking everywhere. Every major retailer every dinky little Shopify store theyre all waving that blue and yellow buttons in your face. But most carders treat PayPal checkouts like kryptonite and for good reason. Those clever bastards at PayPal have been beefing up their anti-fraud systems year after year making it a goddamn nightmare to get through their checkouts.
View attachment 49759
But heres where it gets interesting - Ive been sitting on a method thats been consistently hitting PayPal checkouts for the past two years. This is a fundamental design flaw in their system that they cant just patch away with a quick update. And today Im going to break it down for you step by bloody step.

PayPal Checkout Flow
View attachment 49760
Before we dive into the exploit lets break down how PayPals checkout flow actually works. There are two main paths a transaction can take:
PayPal Express Checkout (Immediate Payment)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal for payment
- Payment processes immediately on PayPals end
- Customer returns to store with completed transaction
- No additional confirmation needed
- Common on basic ecommerce sites
PayPal Standard Checkout (Two-Step Process)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal to authorize (but not process) payment
- Returns to merchant site with PayPal token
- Can still modify shipping/billing details
- Must hit final 'Pay Now' button to complete
- Used by larger retailers for flexibility
View attachment 49766
This second flow - the Standard Checkout - is where our vulnerability lies. That gap between authorization and final processing? Thats our golden ticket. The two-step process creates a window of opportunity that PayPals fraud detection cant easily close without breaking legitimate functionality.
PayPals Fraud Detection
PayPals fraud detection is a multi-layered beast thats been fine-tuned over decades of fighting fraudsters. At its core its built around one critical insight - shipping addresses dont lie. While most payment processors obsess over browser fingerprints and IP PayPal knows that physical orders leave a paper trail you cant fake. Theyve built an extensive database of trusted delivery locations tied to every PayPal account and card thats ever touched their system.
Think about it - that $5 shit card youre trying to use? Chances are its legitimate owner has ordered something through PayPal at some point in their life. PayPal already knows their home address their work address their moms house where they ship Christmas presents. Every successful transaction leaves a footprint in PayPals massive web of trusted locations. When you try to ship that 65-inch TV to some random address theyve never seen before alarm bells start ringing.
This obsession with shipping addresses extends beyond just individual transaction history. PayPals algorithms analyze delivery locations across their entire network building heat maps of legitimate commerce versus suspicious activity. They know which zip codes have high fraud rates which addresses are associated with drops even which buildings tend to see unusual shipping patterns. Your seemingly innocent order gets run through this long list of location-based risk factors before it ever hits the payment processing stage.
But what makes PayPals fraud detection truly formidable is how it combines this shipping intelligence with their massive user data set. Nearly every adult in the US has interacted with PayPal at some point - whether through direct purchases receiving payments or just creating an account they never used. Each of these interactions feeds into their risk models creating an intricate web of trusted relationships and verified behaviors thats nearly impossible to penetrate with traditional carding techniques.
Why Bill=Ship Trick Doesn't Work
Good luck. Unlike regular credit card transactions most sites wont let you change jack shit once a PayPal payment goes through. And theres a damn good reason for that - PayPal is basically their fraud-free guarantee.
Think about it: When you pay with a credit card sites put you through a fraud checks upon fraud checks and all sorts of verification bullshit. But pay with PayPal? That shit gets packed and shipped next day no questions asked. Why? Because these merchants know PayPals fraud detection is god-tier. Theyve seen PayPals track record of shutting down fraudsters and they trust it more than their own mothers.
The merchants logic is simple: Nobodys stupid enough to try carding through PayPal. The risk models are too sophisticated and the data set is too massive. So when they see a PayPal payment come through they treat it like its blessed by the fraud prevention gods themselves as long as no info is changed after payment.
The Shipping Address Switcharoo
Heres where shit gets interesting. Remember that two-step PayPal Standard Checkout flow we talked about? That gap between authorization and final processing isnt just a quirk - its our fucking hammer. To better get the point across lets illustrate it with a random Shopify store.
View attachment 49771
When youre dealing with a Shopify store using PayPal Standard Checkout heres how were gonna fuck with their system:
- Add your shit to cart and proceed to checkout
- At shipping info enter the CARDHOLDERS REAL ADDRESS
- This is crucial - PayPal needs to see an address they trust
- Make sure it matches what PayPal has on records for the card
- Click 'Next' and on the payment page hit that 'Pay with PayPal' button
- PayPal sees a trusted shipping address
- Their fraud detection gets a warm fuzzy feeling
- Authorization goes through clean as a whistle
- Heres where the magic happens:
- After PayPal authorization but BEFORE final confirmation
- Shopify will let you 'review' (unless the store uses Express Checkout in which case it will proceed with the transaction instantly) your order one last time
- This is when you switch that shipping address to your drop
- PayPals already given their blessing they aint checking again
- Smash that final 'Pay Now' button
- Transaction processes through PayPals pre-authorized token
- Shopify gets your updated shipping info
- Package heads to your drop instead of the cardholder
How and Why This Works Like A Charm

Final Thoughts
So there you have it - the holy grail carding PayPal checkout laid bare. Were not just throwing shit at the wall here and hoping something sticks. This is calculated precise exploitation of a fundamental flaw in their checkout flow.
Remember though - this aint some 'get rich quick' bullshit. PayPals fraud detection is still a beast.
And for fucks sake keep your OPSEC tight. Mix up your drops vary your purchase amounts and never reuse the same PayPal account twice.
Class dismissed. Now go make that money - just dont come crying to me when you fuck it up by cutting corners.

Awesome
PayPal is fucking everywhere. Every major retailer every dinky little Shopify store theyre all waving that blue and yellow buttons in your face. But most carders treat PayPal checkouts like kryptonite and for good reason. Those clever bastards at PayPal have been beefing up their anti-fraud systems year after year making it a goddamn nightmare to get through their checkouts.

But heres where it gets interesting - Ive been sitting on a method thats been consistently hitting PayPal checkouts for the past two years. This is a fundamental design flaw in their system that they cant just patch away with a quick update. And today Im going to break it down for you step by bloody step.

PayPal Checkout Flow
View attachment 49760
Before we dive into the exploit lets break down how PayPals checkout flow actually works. There are two main paths a transaction can take:
PayPal Express Checkout (Immediate Payment)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal for payment
- Payment processes immediately on PayPals end
- Customer returns to store with completed transaction
- No additional confirmation needed
- Common on basic ecommerce sites
PayPal Standard Checkout (Two-Step Process)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal to authorize (but not process) payment
- Returns to merchant site with PayPal token
- Can still modify shipping/billing details
- Must hit final 'Pay Now' button to complete
- Used by larger retailers for flexibility
View attachment 49766
This second flow - the Standard Checkout - is where our vulnerability lies. That gap between authorization and final processing? Thats our golden ticket. The two-step process creates a window of opportunity that PayPals fraud detection cant easily close without breaking legitimate functionality.
PayPals Fraud Detection
PayPals fraud detection is a multi-layered beast thats been fine-tuned over decades of fighting fraudsters. At its core its built around one critical insight - shipping addresses dont lie. While most payment processors obsess over browser fingerprints and IP PayPal knows that physical orders leave a paper trail you cant fake. Theyve built an extensive database of trusted delivery locations tied to every PayPal account and card thats ever touched their system.
Think about it - that $5 shit card youre trying to use? Chances are its legitimate owner has ordered something through PayPal at some point in their life. PayPal already knows their home address their work address their moms house where they ship Christmas presents. Every successful transaction leaves a footprint in PayPals massive web of trusted locations. When you try to ship that 65-inch TV to some random address theyve never seen before alarm bells start ringing.
This obsession with shipping addresses extends beyond just individual transaction history. PayPals algorithms analyze delivery locations across their entire network building heat maps of legitimate commerce versus suspicious activity. They know which zip codes have high fraud rates which addresses are associated with drops even which buildings tend to see unusual shipping patterns. Your seemingly innocent order gets run through this long list of location-based risk factors before it ever hits the payment processing stage.
But what makes PayPals fraud detection truly formidable is how it combines this shipping intelligence with their massive user data set. Nearly every adult in the US has interacted with PayPal at some point - whether through direct purchases receiving payments or just creating an account they never used. Each of these interactions feeds into their risk models creating an intricate web of trusted relationships and verified behaviors thats nearly impossible to penetrate with traditional carding techniques.
Why Bill=Ship Trick Doesn't Work
Good luck. Unlike regular credit card transactions most sites wont let you change jack shit once a PayPal payment goes through. And theres a damn good reason for that - PayPal is basically their fraud-free guarantee.
Think about it: When you pay with a credit card sites put you through a fraud checks upon fraud checks and all sorts of verification bullshit. But pay with PayPal? That shit gets packed and shipped next day no questions asked. Why? Because these merchants know PayPals fraud detection is god-tier. Theyve seen PayPals track record of shutting down fraudsters and they trust it more than their own mothers.
The merchants logic is simple: Nobodys stupid enough to try carding through PayPal. The risk models are too sophisticated and the data set is too massive. So when they see a PayPal payment come through they treat it like its blessed by the fraud prevention gods themselves as long as no info is changed after payment.
The Shipping Address Switcharoo
Heres where shit gets interesting. Remember that two-step PayPal Standard Checkout flow we talked about? That gap between authorization and final processing isnt just a quirk - its our fucking hammer. To better get the point across lets illustrate it with a random Shopify store.
View attachment 49771
When youre dealing with a Shopify store using PayPal Standard Checkout heres how were gonna fuck with their system:
- Add your shit to cart and proceed to checkout
- At shipping info enter the CARDHOLDERS REAL ADDRESS
- This is crucial - PayPal needs to see an address they trust
- Make sure it matches what PayPal has on records for the card
- Click 'Next' and on the payment page hit that 'Pay with PayPal' button
- PayPal sees a trusted shipping address
- Their fraud detection gets a warm fuzzy feeling
- Authorization goes through clean as a whistle
- Heres where the magic happens:
- After PayPal authorization but BEFORE final confirmation
- Shopify will let you 'review' (unless the store uses Express Checkout in which case it will proceed with the transaction instantly) your order one last time
- This is when you switch that shipping address to your drop
- PayPals already given their blessing they aint checking again
- Smash that final 'Pay Now' button
- Transaction processes through PayPals pre-authorized token
- Shopify gets your updated shipping info
- Package heads to your drop instead of the cardholder
How and Why This Works Like A Charm
*** Hidden text: cannot be quoted. ***
Final Thoughts
So there you have it - the holy grail carding PayPal checkout laid bare. Were not just throwing shit at the wall here and hoping something sticks. This is calculated precise exploitation of a fundamental flaw in their checkout flow.
Remember though - this aint some 'get rich quick' bullshit. PayPals fraud detection is still a beast.
And for fucks sake keep your OPSEC tight. Mix up your drops vary your purchase amounts and never reuse the same PayPal account twice.
Class dismissed. Now go make that money - just dont come crying to me when you fuck it up by cutting corners.

当您使用 PayPal Standard Checkout 与 Shopify 商店打交道时，他们的系统将如何操作：
- 把你的狗屎加入购物车，然后继续结账
- 在送货信息处输入 CARDHOLDERS REAL ADDRESS
- 这很关键 - PayPal 需要看到他们信任的地址
- 确保它与 PayPal 卡的记录相匹配
- 点击“下一步”，然后在付款页面上点击“使用 PayPal 付款”按钮
- PayPal 看到受信任的送货地址
- 他们的欺诈检测给人一种温暖的模糊感觉
- 授权像哨声一样干净
- 这就是魔法发生的地方：
- 在 PayPal 授权之后但在最终确认之前
- Shopify 将让您最后一次“查看”（除非商店使用快速结账，在这种情况下，它将立即进行交易）您的订单
- 这是您将该送货地址切换到您的投递地址的时候
- PayPal 已经祝福他们不会再次检查
- 按下最后一个“立即付款”按钮
- 通过 PayPal 预授权令牌进行交易
- Shopify 获取您更新的发货信息
- 包裹寄向寄送处，而不是持卡人
它如何以及为什么像魅力一样起作用
隐藏文本：不能引用。***
最后的思考
所以你有它 - 圣杯梳理 PayPal 结账时裸露无遗。不只是在这里向墙上扔屎并希望有什么东西能坚持下去。这是对他们结账流程中根本缺陷的精确利用。
不过请记住 - 这可不是一些“快速致富”的废话。PayPal 的欺诈检测仍然是一头野兽。
看在他妈的份上，保持你的 OPSEC 紧绷。混合您的滴剂，改变您的购买金额，并且永远不要重复使用同一个 PayPal 帐户两次。
课程被解雇。现在去赚那笔钱吧——只是当你偷工减料搞砸了的时候，不要来找我哭泣。

克good？
top notch
PayPal is fucking everywhere. Every major retailer every dinky little Shopify store theyre all waving that blue and yellow buttons in your face. But most carders treat PayPal checkouts like kryptonite and for good reason. Those clever bastards at PayPal have been beefing up their anti-fraud systems year after year making it a goddamn nightmare to get through their checkouts.

But heres where it gets interesting - Ive been sitting on a method thats been consistently hitting PayPal checkouts for the past two years. This is a fundamental design flaw in their system that they cant just patch away with a quick update. And today Im going to break it down for you step by bloody step.

PayPal Checkout Flow
View attachment 49760
Before we dive into the exploit lets break down how PayPals checkout flow actually works. There are two main paths a transaction can take:
PayPal Express Checkout (Immediate Payment)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal for payment
- Payment processes immediately on PayPals end
- Customer returns to store with completed transaction
- No additional confirmation needed
- Common on basic ecommerce sites
PayPal Standard Checkout (Two-Step Process)
- Customer hits 'Pay with PayPal' button
- Gets redirected to PayPal to authorize (but not process) payment
- Returns to merchant site with PayPal token
- Can still modify shipping/billing details
- Must hit final 'Pay Now' button to complete
- Used by larger retailers for flexibility

This second flow - the Standard Checkout - is where our vulnerability lies. That gap between authorization and final processing? Thats our golden ticket. The two-step process creates a window of opportunity that PayPals fraud detection cant easily close without breaking legitimate functionality.
PayPals Fraud Detection
PayPals fraud detection is a multi-layered beast thats been fine-tuned over decades of fighting fraudsters. At its core its built around one critical insight - shipping addresses dont lie. While most payment processors obsess over browser fingerprints and IP PayPal knows that physical orders leave a paper trail you cant fake. Theyve built an extensive database of trusted delivery locations tied to every PayPal account and card thats ever touched their system.
Think about it - that $5 shit card youre trying to use? Chances are its legitimate owner has ordered something through PayPal at some point in their life. PayPal already knows their home address their work address their moms house where they ship Christmas presents. Every successful transaction leaves a footprint in PayPals massive web of trusted locations. When you try to ship that 65-inch TV to some random address theyve never seen before alarm bells start ringing.
This obsession with shipping addresses extends beyond just individual transaction history. PayPals algorithms analyze delivery locations across their entire network building heat maps of legitimate commerce versus suspicious activity. They know which zip codes have high fraud rates which addresses are associated with drops even which buildings tend to see unusual shipping patterns. Your seemingly innocent order gets run through this long list of location-based risk factors before it ever hits the payment processing stage.
But what makes PayPals fraud detection truly formidable is how it combines this shipping intelligence with their massive user data set. Nearly every adult in the US has interacted with PayPal at some point - whether through direct purchases receiving payments or just creating an account they never used. Each of these interactions feeds into their risk models creating an intricate web of trusted relationships and verified behaviors thats nearly impossible to penetrate with traditional carding techniques.
Why Bill=Ship Trick Doesn't Work
Good luck. Unlike regular credit card transactions most sites wont let you change jack shit once a PayPal payment goes through. And theres a damn good reason for that - PayPal is basically their fraud-free guarantee.
Think about it: When you pay with a credit card sites put you through a fraud checks upon fraud checks and all sorts of verification bullshit. But pay with PayPal? That shit gets packed and shipped next day no questions asked. Why? Because these merchants know PayPals fraud detection is god-tier. Theyve seen PayPals track record of shutting down fraudsters and they trust it more than their own mothers.
The merchants logic is simple: Nobodys stupid enough to try carding through PayPal. The risk models are too sophisticated and the data set is too massive. So when they see a PayPal payment come through they treat it like its blessed by the fraud prevention gods themselves as long as no info is changed after payment.
The Shipping Address Switcharoo
Heres where shit gets interesting. Remember that two-step PayPal Standard Checkout flow we talked about? That gap between authorization and final processing isnt just a quirk - its our fucking hammer. To better get the point across lets illustrate it with a random Shopify store.

When youre dealing with a Shopify store using PayPal Standard Checkout heres how were gonna fuck with their system:
- Add your shit to cart and proceed to checkout
- At shipping info enter the CARDHOLDERS REAL ADDRESS
- This is crucial - PayPal needs to see an address they trust
- Make sure it matches what PayPal has on records for the card
- Click 'Next' and on the payment page hit that 'Pay with PayPal' button
- PayPal sees a trusted shipping address
- Their fraud detection gets a warm fuzzy feeling
- Authorization goes through clean as a whistle
- Heres where the magic happens:
- After PayPal authorization but BEFORE final confirmation
- Shopify will let you 'review' (unless the store uses Express Checkout in which case it will proceed with the transaction instantly) your order one last time
- This is when you switch that shipping address to your drop
- PayPals already given their blessing they aint checking again
- Smash that final 'Pay Now' button
- Transaction processes through PayPals pre-authorized token
- Shopify gets your updated shipping info
- Package heads to your drop instead of the cardholder
How and Why This Works Like A Charm

Final Thoughts
So there you have it - the holy grail carding PayPal checkout laid bare. Were not just throwing shit at the wall here and hoping something sticks. This is calculated precise exploitation of a fundamental flaw in their checkout flow.
Remember though - this aint some 'get rich quick' bullshit. PayPals fraud detection is still a beast.
And for fucks sake keep your OPSEC tight. Mix up your drops vary your purchase amounts and never reuse the same PayPal account twice.
Class dismissed. Now go make that money - just dont come crying to me when you fuck it up by cutting corners.
