Golang makes it really simple to code some otherwise arduous tasks. In this case, we needed to sniff raw network data, filter out DNS data, and send the DNS queries and responses to an Elasticsearch cluster. The resulting code is surprisingly simple thanks to libraries such as GoPacket, as you can see below: https://gist.github.com/dvas0004/3d280f95a83a3084b314ea208f19f9e9 The … Continue reading Simple DNS Sniffer in GoLang
