New Side Channel Attacks Re-Enable Serious DNS Cache Poisoning Attacks

Researchers have demonstrated yet another variant of the SAD DNS cache poisoning attack that leaves about 38% of the domain name resolvers vulnerable, enabling attackers to redirect traffic originally destined to legitimate websites to a server under their control. "The attack allows an off-path...

The .io Error – Taking Control of All .io Domains With a Targeted Registration

In a previous post we talked about taking over the .na , .co.ao , and .it.ao domain extensions with varying levels of DNS trickery. In that writeup we examined the threat model of compromising a top level domain TLD and what some avenues would look like for an attacker to accomplish this goal. On...

DNS Poisoning Attacks Made Easy: Judas DNS

DNS Poisoning Attacks Made Easy A DNS proxy server built to be deployed in place of a taken over nameserver to perform targeted exploitation. Judas works by proxying all DNS queries to the legitimate nameservers for a domain. The magic comes with Judas’s rule configurations which allow you to...

The International Incident – Gaining Control of a .int Domain Name With DNS Trickery

ISC reports: Processing of DNS resource records where the rdata field is zero length may cause various issues for the servers handling them. Processing of these records may lead to unexpected outcomes. Recursive servers may crash or disclose some portion of memory to the client. Secondary servers...

DNS BailiWicked Domain Attack

This exploit attacks a fairly ubiquitous flaw in DNS implementations which Dan Kaminsky found and disclosed Jul 2008. This exploit replaces the target domains nameserver entries in a vulnerable DNS cache server. This attack works by sending random hostname queries to the target DNS server coupled...
