I just completed #XSS - Merry XSSMas room on TryHackMe.

I have been diligently at work working on the #adventOfCyber 2025 content again this year, checking the various tasks for #accessibility hurdles and, where possible, providing ways to dodge/hack around them. This wasn't always possible, but at least more possible than the last two years.
Today at 3 PM EST we'll blitz through the last 6 days on stream, showing that while #accessibility issues are rampant, a #screenReader user can absolutely complete the majority of these and might even learn a thing or two in the process!
See you in 6 hours over at https://twitch.tv/ic_null and/or https://youtube.com/@viewpointUnseen #aoc2025 #tryHackMe #thm #selfPromo #stream #tech #blindness
