About the 2016 Grand

• Each team is given vulnerable binaries
• Goal: prevent your binaries from being exploited by malicious inputs, and exploit other teams' binaries

This team's idea

• Built an IDS which captured packets, flagged + blocked anomalous inputs, and stored these flagged inputs in a database
• Used gopacket to store and parse packets
• Problem - program dropping packets, due to too many incoming packets
• Solution - write goroutines for parsing, filtering, storing data. This way, you can operate on a lot of packets at once, in parallel
• Note: they only parallelized storing data, as that was their bottleneck
