GoodbyeGuardian

USE THIS WITH CAUTION

No idea whatsoever on how this went through

IF YOU DO NOT HAVE GOGUARDIAN THIS EXPLOIT WILL NOT WORK FOR YOU

Getting Started

• Obviously (but still needs to be said due to skids in Titanium Network), make sure GoGuardian is actually installed

• Visit the attached URL in a new tab

• On that tab there will be a simple white screen with nothing on it, reload the page

• If the GET request fails and you are left on an error screen (don't panic, this is intended, continue)

• Reload the page for complementary results

• Visit chrome://restart to clear cached sites from GoGuardian

To Undo

• On goguardian.com, press the lock icon at the top left of the screen

• Press cookies and site data

• Click manage cookies

• Then click clear each site's cookies you see there
