Signs to look for
- Redirects only some visitors see. Visitors from Google or on phones get sent to scam or gambling sites, while you see your normal site.
- Spam in Google. Search site:yourbusiness.com and look for pages about pills, replica goods, casinos or pages in another language.
- A warning from Google in search results or Chrome. See getting Google’s hacked warning removed.
- Admin users you didn’t create, or a new owner in Search Console.
- Your host suspended the account or warned about outgoing spam or high resource use.
- Files you don’t recognize, or files changed recently that nobody touched.
- The site suddenly slow, or customers saying their antivirus blocked it.
- A checkout page that looks slightly different, which can mean card skimming. See card skimming on websites.
Check from the outside
- Open the site on your phone over mobile data, from a Google search, in a private window.
- Run Google’s Safe Browsing site status check on your domain.
- Run our free website check and plugin check.
If you find something
Don’t delete everything in a panic; you’ll destroy the evidence of how they got in. Take a backup, change the passwords on the hosting and admin accounts from a clean device, and follow the first hour guide.
