We are seeing some bizarre behaviour on the site. We have legitimate orders on our Magento 2.3.4 site, where the user has created an account with a legitimate set of details including name, address and email address. They complete the sales process, processing payment externally via WorldPay. However, when we view the order, it says, for example:
Customer Name ????????1?6.?004.881? ?????q860-l88-3O6?
How have we ended up in a scenario where the customer profile is correct, the order is legitimate (as confirmed personally with those customers), but these order details are utterly incoherent. Are we under some kind of attack?
I should mention, this is not every order that is affected, but it has been a few.
