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
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.
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,
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.
Security operations and monitoring teams face a variety of challenges: the rapid evolution of adversarial tradecraft
