It isn’t often that old hacking methods make significant news, but an ARP attack received widespread attention earlier this week, more so for the perceived target than for the actual attack itself.

In the seven layer OSI networking model, the second layer includes support for protocols like Address Resolution Protocol (ARP), which is what helps networking devices work out which specific piece of hardware should receive network traffic being sent to a particular network address.

It turned out to be a well-known Chinese hacking group that took credit for the attack. The method they used was very old-school. Interesting article - worth the read.
