In a recent automated attack, a large bot army hacked into accounts using brute-force methodology and a highly accurate username and password list. PerimiterX researchers discovered that by overwhelming sites with requests from a network of tens of thousands of Internet of Things devices such as Canon printers and network devices, and with each bot sending just a single request every 10 minutes or so, the attacker completed more than 5 million attempts per day. Furthermore, the attack was successful on 8% of attempts, breaching a shocking 400,000 accounts per day.
