Why do sites get hacked? Hackers have different motives for compromising a website, and hack attacks can be very different, so they are not always easily detected. Here are some tips which will help you in detecting hacked sites!
Start with our guide "How do I know if my site is hacked?" if you've received a security alert from Google or another party. This guide will walk you through basic steps to check for any signs of compromises on your site.
At Google, we have different processes to deal with hacking scenarios. Scanning tools will often detect malware, but they can miss some spamming hacks. A clean verdict from Safe Browsing does not mean that you haven't been hacked to distribute spam.
Malvertising happens when your site loads a bad ad. It may make it seem as though your site has been hacked, perhaps by redirecting your visitors, but in fact is just an ad behaving badly.
Hackers might want to take advantage of a good site to mask their URLs. One way they do this is by using open redirects, which allow them to use your site to redirect users to any URL of their choice. You can read more here!
Sometimes bad content like ads or other third-party elements unknowingly redirect mobile users. This behavior can easily escape detection because it's only visible from certain browsers. Be sure to check that the mobile and desktop versions of your site show the same content.
Search Console is a tool that Google uses to communicate with you about your website. It also includes many other tools that can help you improve and manage your website. Make sure you have your site verified in Search Console even if you aren't a primary developer on your site. The alerts and messages in Search Console will let you know if Google has detected any critical errors on your site.
If you're still unable to find any signs of a hack, ask a security expert or post on our Webmaster Help Forums for a second look.
