Notes :: Pre-Authentication Remote Code Execution

Pre-authentication Remote Code Execution (Pre-auth RCE) is a critical security vulnerability that allows attackers to execute arbitrary code on a remote system without needing to authenticate. This means that anyone with access to the vulnerable system, often exposed online, can exploit this flaw and potentially gain unauthorized control. What is RCE? Remote Code Execution (RCE) Read More …

TARA – Threat Analysis and Risk Assessment

Threat Analysis and Risk Assessment (TARA) is a critical process in cybersecurity that helps organizations identify, evaluate, and prioritize potential threats to their information systems and data. As cyber threats continue to evolve, understanding TARA is essential for protecting sensitive information and maintaining the integrity of systems. This summary will provide an overview of TARA Read More …

Tools – BEAR: Simulating Advanced Persistent Threats for Cybersecurity Education

For aspiring and new information security professionals, gaining practical insight into real-world attack methodologies is paramount. One tool that offers a unique perspective into advanced threat simulation is “BEAR,” a project found on GitHub. Unlike typical vulnerability scanners or compliance tools, BEAR is a compilation of Command and Control (C2) scripts, payloads, and stagers explicitly Read More …

CRC – Cyclic Redundancy Check

Cyclic Redundancy Check (CRC) is a widely used error-detecting code that helps ensure the integrity of data during transmission or storage. It is a crucial concept in networking and data communication, making it essential for new IT students to understand how it works and its applications. What is CRC? CRC is a method used to Read More …

smbclient test for 445

While smbclient is primarily used for interacting with SMB shares (like listing shares or accessing files),, it can implicitly indicate if port 445 is open and accessible. If smbclient can successfully connect to an SMB share on a target system, it means port 445 is open on that system and allowing connections. How it works: When you use smbclient Read More …

LCP – Link Control Protocol

The Link Control Protocol (LCP) is a critical component of the Point-to-Point Protocol (PPP), which is widely used for establishing direct connections between two network nodes. LCP plays a vital role in the setup, configuration, and management of PPP connections, making it essential for ensuring reliable and efficient data transmission over point-to-point links. Establishing Connections Read More …

Docker GPU Access

Docker containers can effectively allow access to the GPU, particularly through the use of the NVIDIA Container Toolkit, which enables Docker to communicate with NVIDIA GPUs.  This setup is essential for workloads such as AI/ML, deep learning, and data processing that require GPU acceleration to enhance performance.  To enable GPU acceleration, your machine needs a Read More …
