The power of DDoS volumetric attacks is proportional to the number of connected devices in the botnet. Volumetric attacks are perpetrated by leagues of zombie computing devices collectively known as a botnet. As IPv6 comes to represent an increasingly bigger part of your network each year, so too will your exposure to IPv6-based attacks. IPv6-based DDoS attacks today are neither as prevalent nor as big as those happening over IPv4 but they are occurring with increasing frequency and sophistication. All attack vectors that originate in IPv4, be they volumetric or application attacks, can also occur in IPv6.įor the most part an IPv6 network is no more or less vulnerable to DDoS attacks than its IPv4 counterpart but the fact that any vulnerability in v4 can be exploited in v6 is frightening because of the sheer number of vectors and the fact that most security professionals don’t know everything running IPv6 in their network today.
IPv6 introduces not just another attack vector but an attack volume – one that encompasses a parallel universe of all DDoS attacks known today. Although only 25% of websites completely support IPv6 today, many more are supporting v6 in parts of their network, whether their operators know it or not. With IPv6 adoption comes new security challenges. However it’s “here” enough to be a security threat to every organization that has started their migration to IPv6.
We’ve heard it’s been coming for years but no, it’s not here yet.
