Customer creation page - Russian hack / bot attempt?

[Dirt Surfer]

Hello

This morning I woke to find a couple of hundred mail delivery errors in my inbox.

A quick scan of one of the messages indicated it was coming from customer registrations on my Prestashop site.
I noticed that I had hundreds of new customers all of which appear to originate from russia (.ru).

Perhaps they have been created by bots or a hacker so I wanted to delete them and not have them re-register, however when I select them and bulk action delete from 'Manage your Customers' page I get an error Property Customer->firstname is not valid

It appears I cannot delete them while the the First name field is incomprehensible.

1. Can someone suggest a quick fix for this, as I would prefer not to have to go and edit hundreds of entries to change the first name.
2. Also, how can I prevent new customers from creating an ID with incomprehensible name details in future?
3. For that matter, how do I prevent any customers from Russian .RU origin?

What is your PrestaShop version? Invalid names should not be allowed to create a customer account in the first place.

Hi,

Installing a captcha on PrestaShop has become indispensable.
