Over 30,000 websites are hacked every day. Most site owners don't find out for weeks or months — by then, Google has already penalized their rankings, customers have seen warning messages, and the damage is done.
A website hack checker scans your site for signs of compromise: malware, injected spam, hidden redirects, suspicious code, and content that shouldn't be there. The best ones check what Google sees (not just what you see) because many modern hacks are invisible to the site owner.
Our Hack & Malware Scanner goes beyond traditional malware detection. Here's what it checks:
The scanner fetches your page as both a regular browser and as Google's crawler, then compares the results. If Google is seeing different content than you are, it means your site is being used to serve spam to search engines while looking normal to humans.
We scan for over 40 known spam patterns including Indonesian gambling terms (situs slot, judi online, togel), pharmaceutical spam (buy viagra, cheap cialis), casino keywords, and replica goods. These are the keywords hackers inject into compromised sites.
If your English-language business site suddenly contains Chinese, Japanese, Indonesian, Arabic, or Cyrillic text, something is very wrong. The scanner detects unexpected foreign character blocks that indicate injection.
Hackers often load malware through invisible iframes or obfuscated JavaScript (using eval, atob, or unescape functions to hide the actual code). Our scanner flags these techniques.
If your site suddenly links to Indonesian news sites (kompas.com), Russian domains, or other suspicious external sites, the scanner catches it.
Some hacks work by redirecting visitors (or just bots) through a chain of URLs to land on a spam page. We follow the redirect chain and flag infinite loops or suspicious destinations.
If your hosting or firewall is accidentally blocking Google's crawler, your site can't be indexed. We detect this separately from hack indicators — it's not a hack, but it's equally damaging to your search visibility.
Hackers don't always compromise the homepage. In fact, they often target inner pages like /about/, /services/, or /contact/ because site owners check the homepage frequently but rarely look at other pages.
When you enter a domain (not a specific page URL), our scanner automatically checks the homepage plus common inner pages. This catches hacks that homepage-only scanners miss entirely.
Most website security tools scan for known malware signatures in your files. But modern cloaking attacks don't rely on separate malware files — they inject small code snippets into legitimate files that only activate for search engine bots. Your site looks perfectly normal to you, your hosting provider, and even most security scanners.
The only way to catch these attacks is to check what Google actually sees when it crawls your site. That's what our hack scanner does — and it's free to use.
For ongoing protection, our Full Website Audit includes hack detection as one of 8 categories, alongside SEO, performance, security, trust, privacy, accessibility, and content checks. One scan covers everything.
