Hacker TV – GoFetch
This video demonstrates how GoFetch utilizes Bloodhound attack graph data to automatically pivot from an exploited host to the domain controller. The demonstration begins in Bloodhound, where the presenter identifies the attack path to the domain controller. After finding a path, the graph is exported for use by the attack script. The presenter then launches GoFetch 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 …
FCS – Frame Check Sequence
A Frame Check Sequence (FCS) is an essential component in data communication protocols, serving as a method for error detection. It is a sequence of bits added to the end of a data frame, which allows the receiving device to verify the integrity of the data it has received. Understanding FCS is crucial for new 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 …
IAM – Identity and Access Management
Identity and Access Management (IAM) in Amazon Web Services (AWS) is a service that enables users to manage access to AWS resources securely. IAM allows organizations to control who can access specific resources, what actions they can perform, and under what conditions. This is crucial for maintaining security and compliance in cloud environments. Key Features Read More …
