Security researcher Aaron Martin claims the attack was likely the work of an undocumented malware botnet named Brutus.

He made the connection after observing the malwares targeting scope and attack patterns, it was said.

In his analysis of the botnet, Martin said it counts some 20,000 IP addresses worldwide.
