Apparent botnet attack

[Abe Dane]

Earlier today, a Tizra customer (who has been notified) experienced a pattern of suspicious activity consistent with a botnet attack, taking the form of many thousands of failed login attempts over a period of several hours.  Tizra responded by developing software to block the suspicious logins.  This effort appears to have been successful.  The suspicious login attempts have stopped, and it does not appear that the site was compromised.  However, high system loads caused by the attack did cause several minutes of slow performance over the course of the day.
