Defacing websites

 A defacing sample screenshot typically shows a hacked website or digital display where a malicious actor has replaced the original content with their own messages, images, or graffiti. These often serve as visual proof of a security breach or are used to display ransom and political statements. [1, 2, 3, 4, 5]

If you are dealing with a defaced website, your priority should be collecting evidence and securing the server. [1, 2]

What to Capture in a Defaced Screenshot

When documenting a defacement incident (often for an incident report or police complaint), make sure your screenshot clearly shows: [1, 2]

• The altered visual content: The unauthorized messages, modified background, or hacker logo.
• The Date and Time: Visible on your computer's taskbar or in your browser.
• The URL and IP Address: Ensure the web address bar is included in the frame. [1, 2, 3, 4, 5]

Recommended Incident Response Steps

1. Take Evidence First: Before taking the site down, capture screenshots of the defaced page and download the page's source code for forensics. [1, 2]
2. Isolate the System: Take the affected server offline or disconnect it from the network to prevent the attacker from uploading malware or accessing sensitive databases. [1, 2]
3. Restore from Backup: Restore your website using a clean, verified backup and change all administrator passwords. [1]
4. Identify the Vulnerability: Review your server logs and application code to determine how the attacker got in—such as through an SQL injection, XSS, or compromised credentials. [1, 2]
