Akamai Threat Research Team Identifies New Abuses Of OpenSSH Vulnerability

CAMBRIDGE, Mass., Oct. 12, 2016

Overview

It is important to note that the research and subsequent advisory do not introduce a new type of vulnerability or attack technique, but rather a continued weakness in many default configurations of Internet-connected devices. These devices are now actively being exploited in mass-scale attack campaigns against Akamai customers.

The Threat Research Team has observed SSHowDowN Proxy attacks originating from the following types of devices:

• CCTV, NVR, DVR devices (video surveillance)
• Satellite antenna equipment
• Networking devices (e.g. Routers, Hotspots, WiMax, Cable and ADSL modems, etc.)
• Internet connected NAS devices (Network Attached Storage)
• Other devices could be susceptible as well

Compromised devices are being used for:

• Mounting attacks against a multitude of Internet targets and Internet-facing services, such as HTTP, SMTP and Network Scanning
• Mounting attacks against internal networks that host these connected devices

Once malicious users access the web administration console, they have been able to compromise the device's data and, in some cases, fully take over the machine.

"We're entering a very interesting time when it comes to DDoS and other web attacks; 'The Internet of Unpatchable Things' so to speak," explained Ory Segal, senior director, Threat Research, Akamai. "New devices are being shipped from the factory not only with this vulnerability exposed, but also without any effective way to fix it. We've been hearing for years that it was theoretically possible for IoT devices to attack. That, unfortunately, has now become the reality."
