Case board

Someone needs you tonight. Each request is a case: find the leaks in photos, files and writing before anyone else does, and learn not to leave them yourself.

CASE 01

Night Heron

“I turned off location.”

A whistleblower leaks a photo of an internal memo on an anonymous forum. The company says it will find the leaker within 72 hours. Get there first: work out what that photo gave away.

CASE 02

Blue Magpie

“No link, so I thought it was real.”

A “3,480 a month” billing notice with no link, only a line telling you to search for support. People who searched lost their accounts, and the list had their hours of sleep. Find out who sold the member data.

CASE 03

The next case

In preparation. Which privacy topic would you like to see? Tell us.

Three ways to play

Interactive

A simulated investigator’s computer: browser, terminal, image viewer and evidence board. Needs JavaScript; works on phones.

Static

Plain HTML and CSS, no JavaScript. The whole case works at Tor Browser’s “Safest” level.

PDF

Offline or on paper, for reading groups and classrooms. The solution is on the last pages, printed upside down.
