- Be mindful of your sources! Be very careful of a free premium theme/plugin!
You probably have heard about free premium plugins! If you've ever stumbled upon a site offering you plugins you normally have to purchase for free, be very careful. Many hackers lure you in by copying a popular plugin and then add backdoors or malware that will allow them to access your site. Read more about a similar case on the Sucuri blog.

- you do not update them as soon as a new version becomes available
- the developer of said theme or plugin does not update them, and they become old over time

Last week #NoHacked is back on our G+ and Twitter channels! #NoHacked is our social campaign which aims to bring awareness about hacking attacks and offer tips on how to keep your sites safe from hackers. This time we would like to start sharing content from #NoHacked campaign on this blog in your local language!
Why do sites get hacked? Hackers havedifferent 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!
- Getting started:
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.
- Understand the alert on Google Search:
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.
- If you ever see "This site may be hacked", your site may have been hacked to display spam. Essentially, your site has been hijacked to serve some free advertising.
- If you see"This site may harm your computer" beneath the site URL then we think the site you're about to visit might allow programs to install malicious software on your computer.
- If you see a big red screen before your site, that can mean a variety of things:
- If you see "The site ahead contains malware", Google has detected that your site distributes malware.
- If you see "The site ahead contains harmful programs", then the site has been flagged for distributing unwanted software.
- "Deceptive site ahead" warnings indicate that your site may be serving phishing or social engineering. Your site could have been hacked to do any of these things.
- Malvertising vs Hack:
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.
- Open redirects: check if your site is enabling open redirects
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!
- Mobile check: make sure to view your site from a mobile browser in incognito mode. Check for bad mobile ad networks.
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.
- Use Search Console and get message:
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.
The #NoHacked campaign will run for the next 3 weeks. Follow us on our G+ and Twitter channels or look out for the content in this blog as we will be posting summary for each week right here at the beginning of each week! Stay safe meanwhile!
