I just received this email:
There has been 2 unsuccessful attempts to log into ‘ [your URL] ’ using 2 Employee Code ’000264′ & ’000262′. Therefore that IP address has been banned for an hour.
Details of the IP banned:
IP : 188.8.131.52
Location: CANADA – XXXXXXXX
This means that someone (and it may be the same person) has tried to log into the site with 2 different employee codes. This may be a legitimate attempt by an employee, but it could also mean a brute attack with a person or automated system trying different employee codes. To protect your site, we temporarily blocked that IP from trying to log in, and email you a warning.
