Parasitic & Symbiotic Business Models
Does your business model thrive as your customer thrives, or does it drain the life from your customers? After a recent1 conversation on the impact of improved privacy tools (i.e., the eventual elimination of third-party tracking cookies), I realized that the most significant effect of these improvements would be to companies with a parasitic business model. A business model which I see no problem in disrupting. For many years, the web has existed as an advertiser’s dream2 — minimal privacy limitations, technical controls that had little impact, and a strong lobbying arm that has been able to derail many efforts to improve the situation.
Read more…Declaring War on Ransomware
It’s time for everyone from the industry, developers, and the government to declare war on ransomware and make it as hard as possible for them to ply their insidious trade. There have been false starts and baby steps, diligent fighters without enough resources, and vendors that have only given a nod to the issue. It’s time to use every tool reasonably available to stop this scourge. For so many in the industry that have dedicated so much of their time and effort to this fight, this statement may seem to diminish their efforts, but that is not my intent.
Read more…On Automatic Updates and Supply Chain Attacks
Once again, a supply chain attack is in the news; this time, it’s a ransomware attack against Kaseya which has impacted hundreds if not thousands of businesses. According to Kevin Beaumont, the attackers used a 0day vulnerability in the Kaseya VSA appliance to deploy a fake update to all systems it managed; that update is actually the REvil ransomware. As this is a VSA is used by Managed Service Providers (MSPs), this resulted in an attack not just on the MSPs but also their customers.
Read more…Crew Resource Management for Security Teams
Over the last year or so, I’ve become quite a fan of Air Disasters, a television show dedicated to analyzing plane crashes and similar incidents. As I watched the show, I started seeing many ways that the lessons and procedures around aircraft safety also apply to running a security team; this valuable and hard-won wisdom, often born out of tragedy, can be of significant impact if appropriately applied. In this article, I will explore Crew Resource Management and how it can be applied to Information Security to make teams run better.
Read more…Leading Experts
A friend of mine recently asked for my thoughts on leading people who have more experience or expertise in a topic than they do; this is an important question and one that I felt deserved more thought and exploration. Leading people can be difficult, but when leading people that know more than you do about a given topic, it’s a different challenge. This was particularly well-timed, as I’ve found myself in just that situation, as I’ve just hired a specialist in incident response.
Read more…Developers, Developers, Developers
Note: This was written in 2012, but not published at the time. The point is still valid, perhaps moreso than ever and deserves to be made publicly. The content has been updated as appropriate, though the core of this article remains intact from the 2012 draft. I would like to note that this doesn’t apply to every environment, there are some where developers are very knowledgeable about security, and write code with minimal issues – my current employer happens to be one of those rare & exciting places.

The cultural phenomenon that is Hamilton, brought back to the forefront due to its streaming release, is an artistic feat, but it also serves as an opportunity to refresh our memories on the history behind these characters, and look for opportunities to learn lessons that apply today. This is exactly what I’ve been doing. For all of his flaws, one thing that I have to respect about Alexander Hamilton (as well as his wife, Eliza) is the understanding of the long-term impact of the written word.

I recently wrote a review on Active Measures by Thomas Rid – which helped me to solidify my thoughts on social media, and the impact it has on society. While Active Measures is focused on disinformation campaigns, it also speaks to the vulnerabilities in humans that allow these campaigns to work. Disinformation is a substantial issue today, and not just in terms of election interference, public health, or international relations – but also in much smaller scale unorganized efforts to alter perception.
Read more…Utilitarian Nightmare: Offensive Security Tools
Or: Ethical Decision Making for Security Researchers. There has been much discussion recently on the appropriateness of releasing offensive security tools to the world – while this storm has largely come and gone on Twitter, it’s something I still find myself thinking about. It boils down to a simple question, is it ethical to release tools that make it easy for attackers to leverage vulnerabilities that they wouldn’t otherwise be able to?
Read more…Bitcoin is a Cult
The Bitcoin community has changed greatly over the years; from technophiles that could explain a Merkle tree in their sleep, to speculators driven by the desire for a quick profit & blockchain startups seeking billion dollar valuations led by people who don’t even know what a Merkle tree is. As the years have gone on, a zealotry has been building around Bitcoin and other cryptocurrencies driven by people who see them as something far grander than they actually are; people who believe that normal (or fiat) currencies are becoming a thing of the past, and the cryptocurrencies will fundamentally change the world’s economy.
