In order to profit effectively from a ransomware attack, a threat actor needs to have something to offer in return for payment. This blog post outlines a process to encrypt AWS resources and then revoke access to the secret material until the ransom is paid.
Apparently, this post caused some consternation at AWS, and perhaps I should have given them a heads up. So I’m unpublishing it for the time being and giving AWS some time to digest and see if they want to add any mitigations.
Cloud Hygiene is a Cloud Security problem, and we need to cleanup the pollution in our cloud environments
In September 2024, I returned to Stockholm to give a talk at Sec-T. The Slides are here, and the YouTube Video is here.
In the last year or so talking to organizations of all sizes, shapes, and security budgets, it’s become clear there is a deeper problem than just “developers don’t know how to not make a bucket public”. How we as an industry use the public cloud is fundamentally unsafe. We wouldn’t give any random 16-year-old kid with a driver’s license a 787 to fly. Yet, with the public cloud, anyone with a credit card can sign up for one of the most technically complex creations the IT Industry has ever created. Engineers fresh out of school are given access to enterprise cloud tenants and told to deploy their applications. At no point do the cloud providers take reasonable measures to ensure you are qualified to operate the cloud safely, nor are their default auto-pilot settings all that safe.

Multicloud is Madness!!!!
Your organization is doing a poor job protecting the one cloud you have. Why in heaven’s name would you want to deploy into another cloud? In this two-part blog post, we’ll cover details from my HackCon 2024 talk “Chris Farris in the MultiCloud of Madness” (slides). Part one is here, and it covers all the weirdness between the three major hyperscalers - AWS, Azure, and GCP. The second part will provide checklists to help you establish Minimally Viable Cloud Governance in each cloud.
I’m back from re:Invent and still trying to adjust my sleep schedule (I’m on the East Coast and go to bed early; 6 pm Las Vegas time is my biological clock’s bedtime).
This year was one of my favorite re:Invents. I got to meet old and new co-workers and hang out with a lot of Community Builders and AWS Heroes, talk to service teams about what they should do to make their products work more for the security 99%. I got to a couple of good chalk talks on GenAI and GenAI security, which will help inform my poking at that over the holidays.
As for announcements, in the last seven days, there were 195 things posted to AWS What’s New. These are the ones I care to follow up on.
For simplicity, we’ll break them down into:
As has been my tradition the last few years, I prep for re:Invent by reviewing all the interesting announcements that happen in the weeks leading up to the event. This gives me a chance to keep an eye out for sessions and chalktalks related to things I care about, and a chance to corner an SA or product manager at the AWS Booth and go like this:
This year I’ll be attending AWS as a Security Hero. The good news for all 845,000 attendees is that I don’t have to wear tights. Instead I’ll be hanging out in the Heroes lounge with the other Heroes and Community Builders (hopefully sipping mimosas during the keynotes).
I deliberately published an Access Key and Secrets. Here’s what happened.
There is no canonical way to use Terraform in CodeBuild, with CodePipeline as the method to review plans before applying them. This post defines a Cloudformation template and the buildspec files needed to create a CodePipeline that runs terraform plan, allows a human to review it, then runs terraform apply.
With ChatGPT being all the rage, I decided to see if she (it?) could write my next blog post for me. I’d already written all the Steampipe queries and determined the security value behind the blog post. I just didn’t feel like writing it.
The post’s topic was on enumerating your network-plane cloud perimeter.
