Story line

Knocknock is your guaranteed government surveillance evasion service! Hide your message as part of your website and live your underground life worry-free!

Solution

Hide a message in the sequence of API executions, must use VisibleV8 to see the sequences of APIs and recover the flag. If I have time, I'll build a message_generator that takes a message and hides it in JS execution, otherwise I'll craft the sample manually.
