Updates are available for the following models: It’s not clear exactly why or how this backdoor found its way into the D-Link routers, but Heffer said a suggestion by fellow researcher Travis Goodspeed points to one likely explanation: “My guess is that the developers realized that some programs/services [such as dynamic DNS] needed to be able to change the device’s settings automatically,” he wrote.“Realizing that the web server already had all the code to change these settings, they decided to just send requests to the web server whenever they needed to change something.If you’re like many Dyn DNS customers, you have a dynamic IP address which changes periodically (monthly, weekly or even daily).This can make it difficult or impossible to connect to services at home, like remote desktop or FTP.1 Maximum wireless signal rate derived from IEEE 802.11 specifications. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.
The patch closes a backdoor in the devices that could let attackers seize remote control over vulnerable routers.
Router with Firmware 3.36 or greater (3.52 is recommended) and want to learn how to set up DNS updates follow the guide below.
WARNING: Do not use firmware version 3.53, No-IP DDNS support is NOT built into it.
An update client is a computer application or a feature in your router that keeps your hostname’s IP address up-to-date.
The update client periodically checks your network’s IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your Dyn account.
