![Microsoft issues guidance for DNS cache poisoning vulnerability](/static/build/img/news/alt/web-statistics-2-small.jpg)
Microsoft issued guidance on how to mitigate a DNS cache poisoning vulnerability reported by security researchers from the University of California and Tsinghua University. Successfully exploiting the vulnerability could allow attackers to use modified DNS records to redirect a target to a malicious website under their control as part of DNS spoofing attacks.

Jack Wallen walks you through the process of putting in place a temporary fix against SAD DNS for your Linux servers and desktops. There's a new DNS cache poisoning threat in town and it goes by the name of Side-channel AttackeD DNS. This new attack works like so: SAD DNS makes it possible for hackers to reroute traffic destined to a specific domain to a server under their control.

A group of academics from the University of California and Tsinghua University has uncovered a series of critical security flaws that could lead to a revival of DNS cache poisoning attacks. The effectiveness of such attacks has taken a hit in part due to protocols such as DNSSEC that creates a secure domain name system by adding cryptographic signatures to existing DNS records and randomization-based defenses that allow the DNS resolver to use a different source port and transaction ID for every query.
