Ask anyone who’s worked in a SOC long enough and they’ll tell you: debates over “true positive” versus “false positive” happen a lot. Usually, the conversation goes in circles—one person insists an alert was a false positive, another argues it was technically a true positive,
I'm excited to announce the release of CelesTLSH CLI, a lightweight CLI interface tool for calculating, comparing, and analyzing TLSH hashes. This tool is designed to help security professionals quickly identify potentially malicious files by comparing them against a database of known attack tools.
A 1953 mathematical framework reveals how military RADAR research can revolutionize cybersecurity. By transforming threat detection from gut feeling to probabilistic science, signal detection theory offers a powerful approach to distinguishing genuine threats from routine noise.
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.
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.
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.
