Today we assisted a company that was a target of this Malicious Redirect Campain. It shows while you think it might not happen to you, the chances are still quite high.   They are not targetting ‘you’ they are just trying to scan the web for loop holds to add their redirects.  This particular case redirected ALL links to another website, including the backend login link.

    • Affected plugin slugs are prefixed with nd-. Example plugins include Components For WP Bakery Page Builder (slug: nd-shortcodes), Booking (slug: nd-booking), Travel Management (slug: nd-travel), etc.

What can you do to minimise the chances of an attack?

If you need assistance with this so you don’t have to worrk about it, we have website care plans available: https://smartrobbie.com.au/website-maintenance/

 

2. Set up a Sucuri FirewallSucuri is a great service. They can your site every 12 hours for any malware and send reports. They also have a firewall which blocks out any potential hacking. You can set the firewall to only allow backend access to approved IP addresses.  Prices start at $199/year US – https://sucuri.net/.
