Your website, ************, is undergoing a brute force attack.

There have been at least 50 failed attempts to log in during the past 120 minutes that used one or more of the following components:


Component                    Count     Value from Current Attempt

The most recent attempt came from the following IP address: 206.189.88.135

The Login Security Solution plugin (0.56.0) for WordPress is repelling the attack by making their login failures take a very long time.  This attacker will also be denied access in the event they stumble upon valid credentials.

Further notifications about this attacker will only be sent if the attack stops for at least 120 minutes and then resumes.
