“This has happened in the past, and it poses a risk as we saw in the case of the infamous Mirai botnet,” says Avast Security Evangelist Luis Corrons, speaking to the news that the source code to a potent bank trojan known as Exobot has been released into the wild of the dark web for anyone who cares to use it for their own ill will. The publicly-shared Mirai source code gave malware architects the blueprints to a powerful botnet, upon which they expanded. “Many malware writers used it to create their own customized version of the bot. We can expect the same here,” adds Luis.
