About

Hi! I am 21 this year and I’m from Singapore. Cybersecurity is what I’m enthusiastic about 😊. I have no specialization thus far as I am still exploring, but I have experience in fields like digital forensics, reverse engineering and malware analysis, web application security, and penetration testing. Vulnerability research in OSs (including mobile) and browsers is something I hope to also learn. My weaknesses, regrettably, would be applied cryptography and hardware-related topics 😅. We shall see if that ever changes!

The “Top %” statistics are calculated with the exclusion of teams who registered/participated but did not score any points.
The hyphen - usually denotes data that is unavailable.

Site Implementation

The site is built with Hugo, themed with zzo and deployed to Netlify.
I decided to try something different from the usual Jekyll + Github Pages combo, so this is the result!
I’m not at all an expert on web design and development so if you have any suggestions or improvements regarding the site’s accessiblity/usability/performance, feel free to contact me here because I would be eager to learn.

Privacy

The site only uses Google Tag Manager for a single Google Analytics 4 tag that tracks page views! The tag anonymizes IPs by default, and also respects the Do Not Track setting by detecting it with a short script:

1
2
3
4
5
6
function () {
  var dnt = (navigator.doNotTrack || window.doNotTrack || navigator.msDoNotTrack);
  if (dnt == "1" || dnt == "yes") {
    return "1";
  } 
}

Although the zzo theme comes with many other possible analytics integrations, they are not used and disabled. Netlify Analytics is also not used.
In the event that Twitter/Vimeo/Youtube media are embedded via Hugo shortcodes, I have enabled privacy settings in my site’s configuration to respect Do Not Track and also lessen tracking:
