ZERO DAILY

Hacking, AppSec, and Bug Bounty newsletter

2019-03-18 | Jobert’s Unescape Room XSS game, How to get started pentesting, and Security Voices Podcast

Monday, March 18

TOP STORY

Katarina Borodina wrote a thing on how to get started pentesting, good overview to share with friends looking to break into the biz #longlivetheredteam. And on the pentester motif, check out PowerHub by Adrian Vollmer: web application which aids a pentester in transferring files, in particular code which may get flagged by endpoint protection.

TWEET OF THE DAY

Hackers, I've built a small game that helps improve your XSS skills! It dynamically generates (increasingly more difficult) levels for you to exploit XSS vulnerabilities. No level is the same. Let me know what you think. Happy hacking! - @jobertabma
