  Python Deserialization Attack Introduction: How to Build a Python Pickle Bomb

This article introduces an old and classic unsecured Python data serialization feature (the pickle library) and demonstrates how a red team attacker can exploit it to create a malicious binary or text data file that executes remote code or commands upon deserialization. The following attack flow diagram illustrates this process: We will follow 3 steps with the program code to show how Deserialization Attacks Work:   [ Step1 ] Crafting Malicious Data: An attacker crafts a malicious payloa...

  SIEM Big Data Visualization [03]:Graph-Based SIEM Log Analysis Dashboard

Program Design Purpose: The purpose of this program is to develop a Graph-Based SIEM (System Information and Event Management) dashboard that visualizes network communication patterns by processing and analyzing logs from IDS, firewalls, host computers, and other security devices. This dashboard will help security analysts quickly identify and investigate potential threats by using a Cytoscape-style Node-Edge graph for intuitive data representation. The program is an angular plug in which can i...

  A walk through of different ways accessing Kubernetes application

When a web application is deployed on KUbernetes, to access the application, there must be some set up needs to be done so that external users can access the resource within the Kubernetes clusters. IN this post, we will walk through different ways to access application from outside. Before exploring different ways, let's set up a simple nginx eb application which will just serve the nginx welcome message when loading. # deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: ngin...
