We want to bring attention to a critical security vulnerability that recently came across our radar. In today’s digital landscape, safeguarding user data is paramount, and we must remain vigilant in identifying and mitigating risks. Summary: We’ve uncovered a reflected cross-site scripting (XSS) vulnerability within an application’s /auth/v2/login/signin endpoint. This vulnerability allows malicious actors to…

Cross-Site Request Forgery (CSRF) is a type of attack that tricks a user into performing unintended actions on a web application in which they’re authenticated, potentially causing damage or unauthorized transactions. 🔍 Understanding CSRF: Imagine Alice is logged into her bank account. Another tab has a malicious site crafted by Bob, which sends a hidden…

The rise of decentralized apps has made smart contracts more critical than ever. Yet, many startups inadvertently introduce vulnerabilities. Here are 10 common pitfalls: 🛡️ For a deep dive and examples, visit OurWebsite.com/SmartContractSecurity. Ensure your contract’s security is rock solid! Reentrancy: function withdraw() public { uint amount = balances[msg.sender]; require(msg.sender.call.value(amount)()); balances[msg.sender] = 0; } Hardened:…

Cross-site Scripting (XSS) allows attackers to inject malicious scripts into web pages viewed by users. This can lead to a variety of threats, including session hijacking, site defacement, and malicious redirection. Types of XSS: Example Payloads: Vulnerable Code: A basic example of code vulnerable to XSS is a search functionality that directly outputs user input:…

1. DoS (Denial of Service) Example: Imagine a website that can handle 100 simultaneous connections. An attacker writes a script that creates 1,000 connections to the website in a rapid succession. python import requests for _ in range(1000): requests.get(‘http://example-website.com’) This basic script will send many requests to “example-website.com”, potentially overwhelming it if it’s not adequately…
