The one that changes every 30 seconds? That&rsquo;s <strong>TOTP (Time-based One-Time Password)</strong>, and it&rsquo;s one of the most elegant pieces of security technology we use every day.</p> <h2 id="the-problem-with-passwords">The Problem with Passwords</h2> <p>Traditional username-password authentication is inherently vulnerable. Even with complex passwords containing letters, numerals, and symbols, a single data breach from an inadequately secured server or a malicious observer looking over your shoulder can expose your credentials and grant unlimited access to your account.</p>http://ashishji.is-a.dev/blog/posts/hackquest-2025/Fri, 19 Dec 2025 00:00:00 +0000http://ashishji.is-a.dev/blog/posts/hackquest-2025/<p>Cybersecurity is as much about persistence as it is about technical skill. I recently participated in <strong>TCS HackQuest Season 10</strong> (held on December 13, 2025). The competition was intense, featuring a total of 14 challenges ranging from steganography and reverse engineering to web exploitation and binary analysis.</p> <p>Despite some technical hurdles with the server in the final hours, I managed to successfully solve <strong>11 out of the 14 questions</strong>. This writeup provides a brief breakdown of my approach and the logic used to solve each challenge.</p>http://ashishji.is-a.dev/blog/posts/about-this-blog/Tue, 16 Dec 2025 00:00:00 +0000http://ashishji.is-a.dev/blog/posts/about-this-blog/<p>Hi, I’m Ashish. This is my blog, where I:</p> <ul> <li>Document my journey in coding, security, and projects</li> <li>Share writeups of CTF challenges, experiments, and bypasses</li> <li>Explain technical concepts like TOTP, credit card verification, and system internals</li> <li>Record my projects, and everything else</li> </ul> <p>This is a space to learn, reflect, and maybe help someone along the way. Posts range from mini-experiments to full project deep dives.</p> <p>Welcome!</p>
