Hacking, AppSec, and Bug Bounty newsletter
2018-02-23 | Buggy smart contracts, Akamai’s state of the internet, and Snapchat’s $25K bounty
UPDATED to include twitter thread from @dguido providing context on the "Finding The Greedy, Prodigal, and Suicidal Contracts at Scale" paper and we also added a mention of Shopify's 2017 Bug bounty results.
