But even if you can't find an open DNS server to blast recursive responses from, you can still depend on the heart of the Internet for a respectable hail of packet projectiles.

Both errors allow DNS server packet information to be predicted and forged. An attacker can send a malicious Web page link and induce an end-user to click on the link.

Akamai notes that based on APNIC data, approximately 35% of U.S.-based and 30% of internet users worldwide rely on DNS resolvers that use DNSSEC validation and, hence, are vulnerable to KeyTrap.

“And so DNS refers to domain name system. What Packet is enabling people to do is to get a free-for-life web domain, meaning you’ll get your name, whatever you want it to be, pkt, and then you ...

The trouble is that the original Domain Name System specification only allows for 512-byte packets in the DNS protocol. With 13 root servers, we're already well over 400 bytes.

New vulnerabilities are still being found in some of the Internet's oldest functions Amit Klein recently released details on DNS server cache poisoning attacks that affect both BIND (Berkeley ...

DNS Cache poisoning is a relatively old attack, ... In 1997 it was realized that the known source port combined with a non-random transaction ID made DNS packet spoofing rather trivial.

Some DNS-based DDoS attacks use “phantom domains” to either keep a DNS resolver engaged by making it wait for responses or by sending random packets. The DNS resolver consumes valuable ...

Now with the impending deployment of DNSSEC and the eventual addition of IPv6 we will need to allow our firewalls for forward both TCP and UDP port 53 packets. DNS can be used by attackers as one ...

An upgrade to NetContinuum’s NC-1000 network security appliance adds Domain Name System (DNS)-based attack prevention to a list of features that includes prevention of attacks using the HTTP and ...
