A quick fix to prevent brute-force and denial-of-service attacks via repeated POST requests to /admin/ as described in this OpenCart Forum thread: https://forum.opencart.com/viewtopic.php?t=225771
If your site is suddenly extremely slow and you're seeing something similar to this line repeatedly in your server access logs:
"POST /admin/ HTTP/1.1" 200 - "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0"
- then this extension should stop the attackers in their tracks.
You will need vQmod installed to use this extension - download here:
Antropy PayPal Standard Protection
There is a way in OpenCart 1.5.x for customers to adjust the total of an order before it is sent to PayPal, and to therefore place a successful order after only paying a few pence.
If the store owner doesn't notice this, they may well ship the product before realizing that full payment wasn't received.
If the products are digital downloads, the customer may be successful in their attempt to get the products for just $0.01 or £0.01.
This vQmod will check that the amount paid is the same as the order total, and if not, it will set the order status to "Failed".
This extension works with PayPal Standard only.
You must enable IPN in PayPal (easy to do).
No core files modified.
