LabyREnth Teaser Site
Summary: Palo Alto Networks' Unit 42 announced that its second annual LabyREnth capture-the-flag challenge would go live on June 9, 2017, with the first person to solve all challenge tracks winning $10,000. The countdown page carried a teaser that used an obfuscated JavaScript file named wat_do.js with an eval call and an XOR decoding loop, a technique the post compares to the Priv8 web shell's hidden login.
What you should know: The teaser's hiding method - an eval'd, obfuscated script and a hidden input field - is the same pattern the post attributes to the Priv8 web shell, so the skills the CTF rewards are the ones defenders need to spot real malicious pages.
