Hello, Habr! My name is Artem, and I'm the head of the technical expertise center for security analysis at AKTIV.CONSULTING . Today, I'd like to discuss software vulnerability detection during operation and explore whether this is a basic minimum or a luxurious maximum. We'll focus on Process 24...

In this article, I want to share my experience of bypassing root verification on my device. This article can be considered not only as a standalone piece, but also as a direct continuation of my work from the previous article . Disclaimer Let me warn you right away that I like to write articles...

I've been working in IT and information security for over 10 years. And I know that the most difficult risks to prevent are those related to human error. We develop the most reliable security methods. But just one password left publicly accessible will ruin all our efforts. And what can't you...

Part One (You are here) Part Two, Websocket Part Three, gRPC Hello! My name is Sergey, I've been in testing for over 11 years, and during that time I've tried many different approaches in QA—I started as a simple tester, then built and developed various testing and automation departments, and...

While working on any Java application, we come across the concept of optimization. It is necessary that the code we are writing is not only clean and without defects, but also optimized, i.e., the time taken by the code to execute should be within intended limits. In order to achieve this, we...

Web performance has never been more crucial. With users expecting near-instant loading times and smooth interactions, optimizing your web application's performance is no longer optional. In this comprehensive guide, we'll explore modern techniques to boost your web app's performance...

Hello, programmers! As developers, we all strive to write efficient and performant code. However, it's easy to get caught up in the development process and overlook small optimizations that can have a big impact on code performance. Here are a few tips and tricks that I've found useful when...

I'm not talking about skills or knowledge, nor am I trying to sell the world on the idea of performance optimization. Our world already prioritizes speeding up everything. Optimizing code performance is hard work because it's a problem whose very nature dictates the use of brute force—an...

The app is slow. It's the number one complaint developers and architects hear. But "slow" isn't a diagnosis. It's a symptom. This simple word could indicate anything from a poorly written SQL query to a noisy cloud neighbor or an incorrectly configured garbage collector. Performance...

Introduction JSON Web Token (JWT) has gained popularity as a convenient way to authenticate and transfer data between clients and servers. Developers value it for its simplicity, statelessness, and ability to easily transfer user information between services. However, most materials and guides...

Today, we'll discuss how SAST solutions detect security flaws. I'll explain how different approaches to identifying potential vulnerabilities complement each other, why each is needed, and how theory translates into practice. This article is based on the talk " Under the Hood of SAST: How Code...

Introduction to Code Profiling Code profiling is the process of analyzing your application's performance to identify bottlenecks and optimize it. In PHP, as in any other programming language, profiling helps you understand which parts of your code consume the most time and resources. This is...

Profiling Rust programs the easy way Monday, December 4, 2023 Performance is one of the big reasons to use Rust. It's not a magic wand for performance, it just gives you the control to eke out whatever performance you need. So if your program is still slow, how do you fix that? Profiling your...

JavaScript has become one of the most ubiquitous technologies in the modern web browsers. Applications built using client-side JavaScript frameworks such as AngularJS, ReactJS and Vue.js push a lot of functionality and logic to the front-end. As a security tester it is essential for us to...

In this guide, I (hereinafter, "I" refers to the author bl4de ) will show you how to use web browser tools to examine the source code of a web application's client-side. This may seem strange, as a browser is probably not the best choice for such a task, but before you dive in and start...

Probably the most common complaint about Rust is its slow feedback loop and long compilation times. I hear and read about this constantly: in Rust podcasts, blog posts , surveys , conference talks, and offline discussions. As a Rust user myself, I regularly complain about this! Furthermore...

Python is a programming language known for its simplicity and readability, but when it comes to speed, it falls short. This is especially critical when working in machine learning and dealing with huge amounts of data. Today, we'll look at a couple of examples of how to speed up your code out of...

For me, the beauty of C++ lies, first and foremost, in the permissiveness and terrifying power of the language. We can work with memory as tightly as in C, while also having abstraction tools like templates and the STL, where you can parameterize anything and everything. This comes at a price...

Performance is one of the most important issues facing web and app developers. No one wants to see an app crash under heavy load or a page that takes forever to load. Website users aren't willing to wait too long for websites to load or for their pages to become usable. According to Kissmetrics...
