Maintaining online privacy in today’s world is nearly impossible without completely disconnecting—and even then, friends and family may inadvertently expose your information through their own weak security practices. Because of this, many people see the effort as futile and don’t even bother. But I completely disagree. A
When I started in cybersecurity, most web traffic wasn’t encrypted, which meant Firewalls and Network Intrusion Detection Systems played a critical role in detecting malicious activity. Endpoint visibility was limited—most organizations still relied on traditional Anti-Virus
For the past year and a half, I’ve been on one of the wildest adventures of my life, writing a book on UFOs and UAP. It has taken me through a painstaking process of finding and connecting with people who may hold valuable information for my work.
While reading Imminent, a newly released book on UAPs by Luis “Lue” Elizondo, I noticed something intriguing: the text redacted by the Department of Defense was left in plain sight. Naturally, my curiosity kicked in—who wouldn’t want to uncover what’s hidden behind those blacked-out lines?
It is often mistakenly believed that defenders cannot gain visibility into the early stages of the Cyber Kill Chain before the delivery phase.
Five years ago, I co-authored the first public paper on the concept of Detection as Code. While having some technical peers review this paper, we found that a few more advanced security programs were already utilizing this sort of method, just not publicly talking about it.
Throughout my cybersecurity career, I’ve had the opportunity to build three Cyber Security Operation Centers (SOCs) from scratch, including two for Managed Detection and Response (MDR) providers.
Recently, the killer vulnerability research team at Qualys discovered a Remote Code Execution (RCE) vulnerability in OpenSSH that exploits a race condition within SSH. This vulnerability is particularly concerning because SSH is commonly exposed to the internet for remote system management.
The volume and quality of Threat Intelligence for Linux attacks have traditionally lagged behind that for Windows, despite Linux's significant cloud presence. Most reports have focused on reverse engineering Linux-based malware and attack tools.
If you work in cybersecurity or tech, you’re likely familiar with hashing. A cryptographic hash function generates a fixed-size hash value from any given input data. This is a one-way process, making it computationally infeasible to reverse-engineer the original data from the hash value.
This blog post stems from a recent conversation with my former colleague, David Bianco, on the Defender's Dilemma." The Defender's Dilemma is often cited by those without firsthand experience in investigating cybersecurity incidents.
A common trope among cybersecurity practitioners is gatekeeping entry-level positions like junior Security Operations Center (SOC) analysts with statements like, "How are you supposed to secure something if you've never managed it?" This is a concept that I **highly** disagree with.
ATT&CK
Over the past few weeks, I have done a deep dive into the public research available on Linux Ransomware, seeking to understand the broader landscape as there is an over emphasis on the Mirai botnet. I discovered that although there is an abundance of *outstanding* whitepapers and research pieces,
Linux
As someone that primarily does Linux security research, I was frustrated that there wasn't an equivalent of an imphash for Linux ELF binaries. So, I decided to make one myself. Introducing ImpELF.
General
This is a blog dedicated to those like myself who may have an "alternative" background when it comes to getting into cybersecurity.
Detection
Snort rules are considered the gold standard of Network Intrusion Detection signatures, and because of that it is important for new analysts to learn how to read and understand the logic of them. These days, there are a ton of great blogs already on understanding them, such as this one by Rapid7.
Detection
Have you heard of Adversary Emulation platforms, but aren't really sure what they are or how they work? Or perhaps think they are security tools reserved for only the most advanced teams with huge budgets? Let's take a look at what an Adversary Emulation platform is, go over some sample
ATT&CK
An introduction to the Mitre ATT&CK framework, the Mitre ATT&CK Navigator, and some example processes to get you started.
Detection
Lets face it - the state of Linux security monitoring sucks. Linux is often treated as a second class citizen in terms of feature set when compared to its windows counter parts.
Python
This is a guide to setting up a minimal and secure Python development environment for Ubuntu There are a lot of blog posts out there on learning the basics of programming or how to create your first web app with python, but weirdly not very many on how to setup a secure environment.
Detection
Security operations and monitoring teams face a variety of challenges: the rapid evolution of adversarial tradecraft
