Identifying the Hack:
A. Recognize the Signs of a Hacked Website:
Detecting a hacked website in its early stages is crucial for minimizing the potential damage and swiftly initiating the recovery process. Being vigilant and aware of the signs of a hacked website allows you to take prompt action. Here are some common indicators to watch for:
- Sudden Traffic Drop: If you notice a sudden and significant decrease in your website’s traffic, it could be a sign that search engines or security systems have flagged your site as compromised. Hackers may have injected malicious code or content that affects your search engine rankings or leads to blacklisting.
- Unexpected Redirects: If your website visitors are being redirected to unrelated or suspicious websites without their consent, it’s likely that your site has been hacked. Unauthorized redirects can lead to phishing sites or sites that distribute malware, harming your visitors’ experience and your website’s reputation.
