Subject: Failed Login Login Info: Time: 2016年4月23日 11:26 AM Website Info: Site: example.com IP Address: xxx.138.169.207 Notification: User authentication failed: admin Explanation: Someone failed to login to your site. If you are getting too many of these messages, it is likely your site is under a password guessing brute-force attack [1]. You can disable the failed login alerts from here [2]. Alternatively, you can consider to install a firewall between your website and your visitors to filter out these and other attacks, take a look at Sucuri CloudProxy [3].
