Introduction The Flipper Zero is a multifunction device for hacking, security testing and radio frequency protocol exploration. One of its most highlighted features is the ability to transmit and receive SubGHz signals, using the Texas Instruments CC1101 chip, a programmable low-power RF transmitter. SubGHz refers to the range of radio frequencies below 1 GHz (typically between 300 MHz and 928 MHz, depending on the region). These frequencies are used by devices such as remote garage door controls or wireless sensors (temperature, movement, alarms). ...

Introduction️ Webpack is a module bundler for modern JavaScript applications. Its main function is to take modules with dependencies and generate static assets that represent those modules. Webpack can handle a variety of files and convert them into a single file or several files that are more efficient to serve in a web application.️ The source maps are files that map the compressed or transformed code (such as the one produced after compilation and minification with Webpack) to its original source code. These files are extremely useful for debugging, since they allow developers to see and work with the original code in the browser, even if the code actually running has been transformed.️ ...

Introduction️ A blind SQL injection is a type of SQL injection attack in which an attacker attempts to execute SQL commands on a database without receiving direct feedback about the results of queries. However, attackers can infer useful information by observing the application’s behavior or response time. In this case, the technique based on time will be used, although there is also one based on booleans.️ Here, the attacker introduces a SQL query that makes the database wait for a certain time before responding. If the application takes longer to respond, the attacker can infer that the injection was successful. For example, an attacker could try: ...

Introduction️ Firebase Firestore is a NoSQL cloud database provided by Google as part of the Firebase platform that allows developers to store, synchronize and query data in real-time for web, mobile and server applications. Data are organized into individual documents grouped into collections. Each document is a JSON data structure containing key-value pairs.️ Regarding the possible security issues that could be left unprotected by a project that uses Firebase Firestore, here are some points to consider: ...

Introducción The buffer overflow, also known as buffer overflow, is a security vulnerability in software programming that occurs when more data is introduced into a memory area (buffer) than it can handle. This situation may allow an attacker to overwrite adjacent data in the memory, which potentially leads to the execution of malicious code or alteration of a program’s flow.️ When a program does not verify the amount of data entered into a buffer, it risks an attacker exploiting this weakness to inject malicious code, overwrite important information or even take control of the system. Prevention of buffer overflow involves good programming practices and the use of security techniques such as input validation and boundary checking to prevent this type of vulnerability.️ ...

Introduction️ The web MalAPI.io collects a list of Windows APIs that can be used by malicious programs to perform unwanted actions on the operating system. To analyze executables in search of these strings, a Python tool has been developed that automatically scans the file passed as a parameter.️ Use of MalAPI Scanner️ To use, simply pass the executable file to analyze as a parameter and have the malapi.json file in the same directory with the API database extracted from the website. This is an example of its execution.️ ...

Introduction️ A MPEG-TS file is a file format used to transmit video, audio and other types of data in digital broadcasting systems, such as terrestrial digital television (TDT). HbbTV (Hybrid Broadcast Broadband TV) is a specification that combines traditional broadcast television with internet-based services. HbbTV uses standard web technologies like HTML, JavaScript and CSS to provide this interactive experience for users.️ The Application Information Table (AIT) is an important part of the MPEG-TS standard used specifically in the context of HbbTV. The AIT table provides information about interactive applications available for a particular digital television service. It contains metadata related to the applications, such as their name, description, application type, launch URL, etc.️ ...

Introduction️ DVBSTP (Digital Video Broadcasting - Stream Transfer Protocol) is a standard protocol developed by the DVB consortium for the efficient and reliable distribution of broadcast digital data streams, such as digital television signals, digital radio and other multimedia services.️ DVBSTP is mainly used for transmitting data in IP (Internet Protocol) networks over asynchronous transmission networks. It provides mechanisms for error management, flow control and data recovery to ensure the integrity and quality of digital broadcasting services.️ ...
