Fraud user was able to purchase domain without paying ! How?

[ramystyle]

Hi,

 

We received a new client registration that was obviously bogus because of the first, last name (asdfas asdfasdf) phone number (123123123123) etc...

 

When the user registered, we got an email from Telesign saying there was an error and the account was suspended. (See attachment).

 

A minute later, we receive an email for a domain name registration. I quickly logged in to whmcs and checked if the user has paid. The paypal payment was a Failed one and yet the domain + ID Protection were active in his account !

 

How could that be ?

 

I quickly banned the user's IP and canceled his account.

 

Has anyone had this happen to them before? We were using version 5.2.7 when this incident happened.

 

Thanks !

Did the client pay using paypal, initially a valid payment caused the order to complete, then the payment was detected as fraud by paypal and they retracted it from you?

 

I'd check to see if the payment succeeded, even if only for a few moments, it would be enough to validate the order.

I checked the Gateway logs and there's no trace of paypal.

The invoice is marked as Canceled ! I logged in to Paypal and nothing !!

 

I heard that Telesign no longer support whmcs. Could that be why ?

After investigating, we finally understood how that happened.

It appears a hacker was able to obtain login/pass of one of our admins. So he logged in, created a fake user and purchased the domain within whmcs admin area then canceled the invoice.

 

Thanks to whmcs logs, we were able to understand what happened. We "Directory passworded" our admin area and changed all passwords to prevent future attacks
