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 …

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 …

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 …
