Current projects:

[X] Curl-based REPL
[X] Blind data extractor
[X] API identifier
[ ] Polish tools
[ ] Write docs
[ ] Add repos
      

Planning on combining these into a little web security toolkit eventually. The API identifier will focus on more exotic APIs and will be called "APID".


>> Write-Ups

In May of 2020, I hacked nearly every active Windows machine on HackTheBox, earning me "Hacker" rank. Currently, I'm working on HTB's Pro Labs in order to gain more experience in lateral movement, persistence, and other intranet post-exploitation techniques.
