01 Website Malware 101
Website malware is any malicious script or software that has been injected into your website's files or database by an attacker.
Unlike desktop malware, website malware often remains silent and invisible to the site owner, while it silently steals data, redirects visitors, or turns your server into a bot for larger attacks.
Web Shells
Backdoors that give attackers full control over your server.
SEO Spam
Injecting thousands of junk pages to hijack your search rankings.
Redirectors
Sending your visitors to malicious third-party websites.
02 Detection Methods
How does a modern scanner find malware that is designed to stay hidden?
Remote Scanning
Analyzing the public-facing code of your site for suspicious iframe injections, obfuscated JavaScript, and malicious patterns.
Blacklist Surveillance
Constantly checking your domain against authorities like Google Safe Browsing, Norton Safe Web, and McAfee SiteAdvisor.
Behavioral Analysis
Monitoring if your site tries to perform unexpected actions, like initiating downloads or making cross-domain requests to known command-and-control servers.
03 Frequently Asked Questions
How do I know if my website has malware?
Common signs include browser warnings (Google Red Screen), unauthorized redirects, strange code appearing in your source, or your hosting provider suspending your account.
Can malware hide in images?
Yes. Attackers can hide malicious scripts in image metadata (steganography) or exploit vulnerabilities in image processing libraries to execute code.
Is free malware scanning enough?
External scanners can detect public-facing malware and blacklisting. However, for a deep clean, you should also use server-side scanners that can see your files and database.
