If your website is hacked, the first step is to contact your hosting provider. They can help you assess the damage, restore from backups, and secure the compromised server. Often, hosts will help you identify the vulnerability that was exploited, whether it was outdated software or weak passwords. Once the breach is fixed, change all passwords, update your website and server software, and scan for malware. Additionally, review your security settings and implement stronger defenses, such as firewalls, malware protection, and regular backups, to prevent future attacks.
