Abstract
<p>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 <i>60 milliseconds</i>?</p>

<p>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. </p>

<p>This talk will be the first public anatomy of an attack on a server-less application deployed to AWS Lambda and AWS API Gateway. It'll be useful for any application developer looking to build a server-less application, and for any hacker who's come up against this interesting new class of application.</p>

<p>First, we'll take a look at the current state of server-less architectures and show some common deployment patterns and how they're used in production, comparing the advantages and trade offs against traditional monolithic servers.</p>

<p>Next, we'll explore the attack surface of a server-less application, showing that where Satan closes a door, he opens a window. Using exploitables in common server-less patterns, we'll use cloud event sources as a vector for delivering our obfuscated payload.</p>

<p>Then, we'll use some undocumented features in AWS Lambda to persist our malware, explore the Lambda environment looking for secret keys and other buried treasures, and pillage a remote database.</p>

<p>Finally, we'll use a few more tricks to sneak out of the VPC with our precious data in tow! And, of course, we'll tidy up after ourselves leaving the DevOps team none-the-wiser.</p>
