NewSky Security’s honeypots have detected a new IoT botnet in the making. The botnet was named DoubleDoor, as it leverages two distinct backdoors to get to the target: ZyXEL PK5001Z modems. The DoubleDoor attacks What’s interesting about this particular botnet is that it’s ready to pass an extra layer of security to get to the modem: Juniper Networks’ NetScreen hardware firewall devices. To pull off the attack, it employs exploits for two vulnerabilities: CVE-2015–7755, which … More ?
