When WhatsApp added end-to-end encryption to every conversation for its billion users two years ago, the mobile messaging giant significantly raised the bar for the privacy of digital communications worldwide. But one of the tricky elements of encryption—and even trickier in a group chat setting—has always been ensuring that a secure conversation reaches only the intended audience, rather than some impostor or infiltrator. And according to new research from one team of German cryptographers, flaws in WhatsApp make infiltrating the app’s group chats much easier than ought to be possible.

At the Real World Crypto security conference Wednesday in Zurich, Switzerland, a group of researchers from the Ruhr University Bochum in Germany plan to describe a series of flaws in encrypted messaging apps including WhatsApp, Signal, and Threema. The team argues their findings undermine each app’s security claims for multi-person group conversations to varying degrees.

But while the Signal and Threema flaws they found were relatively harmless, the researchers unearthed far more significant gaps in WhatsApp’s security: They say that anyone who controls WhatsApp’s servers could effortlessly insert new people into an otherwise private group, even without the permission of the administrator who ostensibly controls access to that conversation.
