Why is “This site may be hacked by a third party” displayed?

Google searches and indexes its own site. Among them, a specific domain is blacklisted and a link to that domain is embedded in the site, or an illegal file (JS etc.) is read on the site’s HTML and the site detects it Judges that it has been tampered with.

Finding malicious behavior of a hacked site

When WordPress is tampered with, various symptoms appear on the management screen and site access. Here are some typical examples:

● There are user who you didn’t activated
● The number of accesses is increasing or decrease rapidly
* It often appears in the server access log, not in the access analysis.
● The number of emails is increasing rapidly
* This is the case for spam. It often appears in the server access log
● A lot of words and URLs with unknown meanings are written in comments
● A large number of folders and files are increasing in WordPress FTP without your knowledge.
● The site became very heavy
* When a falsified file reads an illegal file, the illegal file distribution may have already disappeared, and the site becomes heavy because this file cannot be obtained.
● Some functions cannot be used on the management screen.
● The site suddenly collapsed
● Can not log in
* There is a possibility that the password of the administrator authority has been rewritten.
