Lately, we have noticed many injection attempts from 172.245.168.36. Wordfence blocks these attacks with the following message: “Blocked for XSS: Cross Site Scripting in POST body”.
If a new user with admin privilege is created, that means your website is compromised, and you should address the situation as soon as possible.

Cleanup steps

• Clear “zeroday2024.com” or “tapspowdercoating.instawp.xyz” scripts using a search and replace tool.
• Switch all the users with administrator rights except the one you’re using and change your password afterward.
• Perform malware cleanup, making sure all the site components including plugins, themes, and core files are malware-free.
• Check to see if your domain is blacklisted by any security vendor.
• If your website was affected by malicious redirects, verify your URL with GSC and ask for a re-index.
• Monitor the website, check for any suspicious activity, and install a firewall.
