Introduction As organizations accelerate their migration to the cloud, identity has become the cornerstone of modern security architectures. Traditional network perimeters have dissolved, replaced by authentication and authorization mechanisms that rely heavily on tokens, sessions, and contextual trust. This evolution has significantly improved usability and scalability—but it has also introduced a new class of threats.…
Kerberos is one of the most robust authentication protocols ever designed for enterprise environments. Its strength, however, does not rely solely on cryptography, but on a strict trust model enforced by the Key Distribution Center (KDC). When that trust model is misdesigned or poorly maintained, Kerberos can become a powerful attack vector capable of leading…
Data exfiltration—also known as Data Exfiltration—refers to the unauthorized transfer of sensitive information outside a secure corporate environment. This risk has become one of the top security concerns, as it can lead to theft of confidential information, reputational damage, and significant financial losses. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the…
This tutorial provides an in-depth exploration of the LockBit ransomware, one of the most sophisticated and dangerous ransomware strains in 2024. This blog is designed for cybersecurity professionals, IT administrators, and businesses aiming to understand the mechanics of ransomware attacks and how to defend against them. It combines technical insights, practical attack simulations, and mitigation…
Cybersecurity is a top priority in the digital age, where cyber threats to systems and networks are increasing every day. One of the key tools for protecting computer systems is the Host Intrusion Detection System (HIDS). This article details how HIDS works, its benefits and provides practical examples for a better understanding. What is a…
Security in corporate networks has become more complex with the increasing diversity of devices and users connecting to them. One of the most effective solutions for managing and securing network access is NAC (Network Access Control). This article explores in detail what NAC is, how it works, its components, and practical examples of its application…
Nowadays we all know what an antivirus is, we know what we must have to stop a virus from entering our computer and making it unusable. The basic theory is fine, but to really know in depth what an antivirus does? I will explain in depth what it is and the reason for having it.…
Command injection is a cyberattack that involves the execution of arbitrary commands on a host operating system (OS). Typically, the threat actor injects the commands by exploiting an application vulnerability, such as insufficient input validation. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the only purpose of learning. We do not promote…
A proxy is a well-known technology in the market, although sometimes it is not well understood how it works. Therefore, in this opportunity we will explain what a proxy is and how it is useful. But before we start talking about the logical structure of proxy servers, I consider it important to clarify how it…
Code injection is the general term for attack types that consist of injecting code that is then interpreted/executed by the application. This type of attack takes advantage of mismanagement of untrusted data. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the only purpose of learning. We do not promote its use for…
