I recently helped a company recover their data from the Akira ransomware without paying the ransom. I'm sharing how I did it, along with the full source code. Update: since this article was written, a new version of Akira ransomware has appeared that can't be decrypted with this method The c

You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
I don't think that it's impossible for politicians, even nontechnical politicians, to make good tech policy. After all, the fact that no one in Congress is a microbiologist doesn't stop federal standards from delivering potable water (and it doesn't excuse the ghastly failures, such as Flint, MI):
It's normal for post-quantum cryptography to be rolled out as an extra layer of security on top of traditional pre-quantum cryptography, rather than as a replacement .
There's no silver bullet, but if we put some "lead" bullets in the right places, we have a good shot at keeping sensitive data out of logs.

TL;DR : GitHub Actions provides a policy mechanism for limiting the kinds of actions and reusable workflows that can be used within a repository, organization, or entire enterprise. Unfortunately, this mechanism is trivial to bypass . GitHub has told me that they don’t consider this a security issue (I disagree), so…
We are building a comprehensive archive and analysis project examining published documents leaked by Edward Snowden. Our methodology involves systematically reviewing each available document with particular attention to small details and information that has received little or no public attention since the initial…
Shipping large software to end-user devices is a complicated process. Shipping large software securely to end-user devices is even more complicated. Signing the things that ship to end-user devices is
An employee at Elon Musk’s artificial intelligence company xAI leaked a private key on GitHub that for the past two months could have allowed anyone to query private xAI large language models (LLMs) which appear to have been custom made for working with internal data from Musk’s companies, including SpaceX , Tesla and…

You don't own your email; you rent it. This vulnerability leaves your entire digital life at risk. Read how to seize back control of your most critical online asset by switching providers and setting up your own unbannable email server.
Ten years ago this week, in May 2015, the JSON Web Token (JWT) became RFC 7519 . This was the culmination of a 4.5 year journey to create a simple JSON-based security token format and underlying JSON-based cryptographic standards. The full set of RFCs published together was:
Serverless means it's secure, right?
In January, Distributed Denial of Secrets published over 200 gigabytes of chat logs and recordings from paramilitary groups and militias, including American Patriots Three Percent (APIIII) and the Oath Keepers. The files were obtained by John Williams, a wilderness survival trainer who spent years deep undercover…
Some memory corruption bugs are much harder to exploit than others. They can involve race conditions, crash the system, and impose limitations that make a researcher's life difficult. Working with such fragile vulnerabilities demands significant time and effort. CVE-2024-50264 in the Linux kernel is one such hard bug…
Happy New Year! Or so I thought. After a refreshing Christmas vacation with my family, I was stashing something away in our storage room when I noticed the server fan running at maximum speed. This was very unexpected, considering my server is powered by an Intel i3 and should handle all the light tasks I run quite…
Claimed end-to-end privacy doesn’t fully conceal your rear-end data

What started off as casual scrolling through the KernelCTF submissions quickly spiraled into a weeks-long deep dive into a deceptively simple patch - and my first root shell from a Linux kernel exploit!
In this blog post, you will learn about the security oriented smartphone operating system GrapheneOS
Late last year, security researchers made a startling discovery: Kremlin-backed disinformation campaigns were bypassing moderation on social media platforms by leveraging the same malicious advertising technology that powers a sprawling ecosystem of online hucksters and website hackers. A new report on the fallout…
Since I reside in a Five Eyes country (Australia) and have publicly presented four cases I led on China’s APT41 attacking organisations in ASEAN , particularly concerning China’s cyber and political strategies, I was curious to explore what China publishes about Five Eyes operations. This led me down a rabbit hole of…
The Cinema Industry is using its own standards for creating and distributing movies in a secure way. The DCI (Digital Cinema Initiatives) specification defines everything from file formats and encryption to the projection systems itself.
After 10 years as an AWS customer and open-source contributor, they deleted my account and all data with zero warning. Here's how AWS's 'verification' process became a digital execution, and why you should never trust cloud providers with your only copy of anything.
I wanted to know what third-party code I was using in my GitHub Actions. I was able to use standard text processing tools and shell pipelines to get a quick tally.
What the government didn't reveal is how many zero days it discovered in 2023 that it kept to exploit rather than disclose. Whatever that number, it likely will increase under the Trump administration, which has vowed to ramp up government hacking operations. In a first-of-its-kind report,
