As part of an ongoing project to implement version control and configuration management for all aspects of my infrastructure, I have recently moved the hosting for my Tor Hidden Services onto my main web infrastructure, rather than using a separate dedicated machine. Both of my web servers are set up and managed entirely using Ansible, so I had to put together a new Ansible playbook to install and configure Tor. I've documented it here if anyone else may find it useful.
The configuration described in this article is intended for use on Debian/Ubuntu-based systems, however with minor modifications it should be usable on other systems as well. Continue reading...

One of the most common implementation challenges of security.txt is Content Management Systems or managed hosting providers that don't allow you to set the file correctly. For example, they may disallow writing to the
/.well-known directory, or it may not be possible to serve files as the
text/plain MIME type.
If this is the case, and you also happen to be fronting your website using Cloudflare, you can use Cloudflare Serverless Workers to serve the file directly from Cloudflare, instead of passing the request through to your origin server/hosting provider.
Serverless, also known as functions-as-a-service (FaaS), allow you to run your code in the cloud, without having to rent individual virtual machines or use traditional shared hosting. Instead, your code runs in short lived and isolated sandboxes on a machine with potentially hundreds of other customers' sandboxed code. Deployment, scaling, resilience and system security is all managed by the serverless provider. You are generally billed per execution or for the amount of CPU time used, making serverless much more cost efficient than other cloud computing models in many cases. Continue reading...

I've developed a Bash script that can automatically download and perform integrity verifications for various pieces of software, including Ubuntu ISOs, Kali Linux and some Windows software.
The reason for creating this is to make it significantly easier, more reliable and faster to acquire integrity-checked versions of the software that I regularly use. Previously, downloading and updating this software was a manual process, which is naturally slow and unnecessarily prone to human error.
I've released the script under the MIT license, and it's available on my GitLab profile: https://gitlab.com/jamieweb/dl-integrity-verify Continue reading...

Earlier this year, I was interviewed by Giulio D'Agostino for his new book and podcast 'Conversations in Cyberspace'. My podcast episode has now been released - if you'd like to listen, it is available on Anchor.fm, and various other platforms:
During the interview, I was asked about multiple topics including reverse engineering, Tor Onion v3 services, Linux and the browser extension ecosystem. I hope you enjoy, and thank you again to Giulio for having me on the show!
Please note that I have no commercial affiliation with Giulio or any of his projects. Continue reading...
