Permanent Disclosure Ledger

The discipline, demonstrated

On behalf of our research partners, we investigate publicly distributed Android and iOS apps: we decompile them, follow their code and data flows, and trace every connection to the servers it reaches. Hundreds of agents work through each app and join the technical evidence into one picture, which our specialists then review and verify.

Tchibo's app automatically starts a session-recording tool and a screen-overlay component the moment it opens, and can remotely push up to 22 different tracking tags to your phone without an app update. It also carries a hardcoded tracking token, and a location-based marketing tool begins working the instant your phone restarts, before you have opened the app at all.
