any ctfs this weekend?

Hi! Welcome to my blog~ You can find ctf writeups, vuln research posts, and other cybersecurity-related stuff here!

I’m Lucas, a 19-year-old Singaporean currently serving in National Service. I have a burning addiction for ctfs, and also do some web dev on the side.

I main pwn and web, and am currently learning kernel pwn, v8, and blockchain. I currently participate with slight_smile and WreckTheLine.

Outside of playing ctfs, I also love building keyboards and listening to k-pop!
