More and more businesses are moving away from monolithic servers and turning to event-driven microservices powered by cloud function providers like AWS Lambda. So, how do we hack in to a server that only exists for 60 milliseconds?

This talk will show novel attack vectors using cloud event sources, exploitabilities in common server-less patterns and frameworks, abuse of undocumented features in AWS Lambda for persistent malware injection, identifying valuable targets for pilfering, and, of course, how to exfiltrate juicy data out of a secure Virtual Private Cloud.

My Cat Alerted Me to a DDoS Attack - Danny Guo

A few years ago, my cat gave me my most memorable middle of the night software engineering incident. I was working at a startup, and we didn’t have a formal on-call rotation yet. That was a deliberate decision, since being on-call is painful, and the team was good about just collectively keeping an eye out for urgent alerts. We eventually set up an on-call rotation, but before that happened, I had a fun night.

It's not a supply chain, dummy! - CrankySec

Hello friends! Hope your weekend plans did not go to shit because of some open source library you have no clue if it's being used in your environment or not because, well, let's face it: nobody fucking knows these things. Nobody has time for this. YoloOps is alive and well, boys!
Here's the thing that you will absolutely see written everywhere by some dumbass sycophant: "We need to secure the software supply chain!" Sure thing, bro. One problem, though: in order for a supply chain to be a supply chain, the chain must be comprised of suppliers. The masochist hero maintaining that library you just npm install without even thinking about it is not your fucking supplier.
