Security Vulnerabilities in AT&T Routers
How to Change DNS Server Settings: Router vs Device Enter the new DNS servers that you'd like to start using in the DNS settings area, usually located alongside the other network configuration options in the device or computer you're using. Learn how to check for and prevent VPN leaks with the help of DNS servers and using a router with DD-WRT or Tomato open-source firmware. Preventing VPN leaks with the help of DNS server setups is an important part of keeping your path on the Internet private. Nov 01, 2018 The modem is usually separate from the router. If your Internet connection uses a router/modem combo, this method most likely won't work for you. This method is most effective for home connections with OpenDNS parental controls installed. Feb 03, 2014 and when i check tor connections in commodo,i dont see any UDP out connection on port 53,just TCP out at 443 and 9001 ports.I think ip related for 443 port is the tor entry node and ip related to 9001 port is dns server used. If it used two NIC’s it could just grab port 53 and do a bit of fixing to the packets to ensure that they all go to the DNS service that you want them to go through.

They're actually Arris routers, sold or given away by AT&T. There areseveralsecurityvulnerabilities, some of them very serious. They can be fixed, but because these are routers it takes some skill. We don't know how many routers are affected, and estimates range from thousands to 138,000.

Among the vulnerabilities are hardcoded credentials, which can allow 'root' remote access to an affected device, giving an attacker full control over the router. An attacker can connect to an affected router and log-in with a publicly-disclosed username and password, granting access to the modem's menu-driven shell. An attacker can view and change the Wi-Fi router name and password, and alter the network's setup, such as rerouting internet traffic to a malicious server.
The shell also allows the attacker to control a module that's dedicated to injecting advertisements into unencrypted web traffic, a common tactic used by internet providers and other web companies. Hutchins said that there was 'no clear evidence' to suggest the module was running but noted that it was still vulnerable, allowing an attacker to inject their own money-making ad campaigns or malware.
I have written about router vulnerabilities, and why the economics of their production makes them inevitable.

The problem with traditional firewalls is that they leave port 53 open, which is for DNS queries. So they are not always effective in protecting against DNS-based DDoS attack such as amplification, reflection, etc. They require extremely high compute performance to accurately detect DNS-based attacks, making deep inspection an impractical approach in terms of cost and the number of distribution points that are needed. Hence traditional protection is ineffective.

DNS cannot go down and if a DNS service goes down, network attached devices stop working. A company loses connectivity to the internet and hence cannot conduct business online. This leads to loss of revenue, customer defection and negative brand impact. Here are the top DNS attacks to look out for:
