There’s no ‘backdoor’ in WhatsApp

WhatsApp users were thrown into a panic Friday morning after a news claimed a use has a backdoor that could concede messages to be intercepted.

But cryptography experts and WhatsApp contend that explain is fake — people can continue regulating a app meaningful their messages are secure.

A report from a Guardian pronounced a “security backdoor” could concede WhatsApp or supervision snoops to prevent messages.

But a confidence researcher who a Guardian cited called it a vulnerability (not a backdoor). In an April blog post, Tobias Boelter explained how WhatsApp’s confidence structure could potentially concede someone to prevent messages by sanctimonious to be a recipient.

In fact, this supposed disadvantage is a pattern choice done by WhatsApp so chats can upsurge uninterrupted.

WhatsApp encrypts messages on devices. So when a summary is sent to a target who only got a new phone or doesn’t have a app installed, a summary arrange of floats in messaging purgatory, corroborated adult on a sender’s phone until a recipient’s device is activated and a summary is delivered.

An assailant could theoretically prevent corroborated adult messages by operative with Facebook (FB, Tech30) (which owns WhatsApp) to change a recipient, or by sanctimonious to be a target by induction a new device with a recipient’s stolen phone number.

You can capacitate a environment on WhatsApp that will warning we when your crony changes inclination after your summary is delivered. You should ask your crony in chairman or by a opposite channel to endorse that they altered inclination if you’re disturbed about security.

Though not a backdoor, a disadvantage does prominence an emanate debated by the cryptography community: What should an encrypted communication app do when someone switches phones? Apple (AAPL, Tech30) and WhatsApp have motionless to keep a review flowing. Signal, another encrypted messaging app, won’t send your message, and will also warning we that there’s been a device change.

On Thursday, Google (GOOGL, Tech30) published documentation so developers could try and solve this problem.

WhatsApp is perplexing to make it reduction frustrating to speak with people who mostly change devices, according to Zaki Manian, owner of blockchain association Skuchain and house member of a polite liberties classification Restore a Fourth.

“We’re articulate about a choice in pattern that both iMessage and WhatsApp have made,” Manian said. “But it potentially creates a approach in that we could potentially prevent one message.”

Cryptographer and former Signal developer Frederic Jacobs also took emanate with a “backdoor” claims.

It’s absurd that this is presented as a backdoor. If we don’t determine keys, flawlessness of keys is not guaranteed. Well famous fact.

A orator for WhatsApp told CNNMoney that it does not give governments a backdoor, and pronounced a association would quarrel any supervision ask to emanate one.

“The pattern preference referenced in a Guardian story prevents millions of messages from being lost, and WhatsApp offers people confidence notifications to warning them to intensity confidence risks,” a orator said.
