Critical WhatsApp Security Flaw Allows Hackers to Infiltrate Your Group Chats

The world'southward almost popular messaging app may claim to exist an ultra-secure fortress, but perhaps it may demand to take a rethink after a critical WhatsApp security flaw was exposed.

Security researchers from Ruhr Academy Bochum, Federal republic of germany have unearthed a number of security vulnerabilities in encrypted messaging apps such as WhatsApp, Bespeak and Threema. The squad revealed their findings at the Real Globe Crypto security conference Wednesday in Zurich this calendar week. While all 3 aforementioned apps are afflicted by one vulnerability or another, the one affecting WhatsApp seems to be the about serious.

Co-ordinate to the researchers, an inherent pattern flaw in the Facebook-endemic chat app lets anyone in control of the WhatsApp servers insert new people into private group chats without needing admin permission, despite promises of finish-to-end encryption.

While every fellow member of the group volition withal receive notifications about a new member joining the group, the Ruhr University team says that an intelligent hacker in control of WhatsApp servers can use a few different workarounds to avoid, or at to the lowest degree filibuster, detection.

WhatsApp's Response

While WhatsApp admitted the findings of the researchers, a company spokesperson in a telephonic conversation with Wired, still insisted that notifications will go out to each existing member about whatsoever new entrant to a group. "We built WhatsApp so group messages cannot be sent to a subconscious user," the report quoted a spokesperson as maxim on email, about the WhatsApp security flaw.

Meanwhile, Facebook'southward Main Security Officeholder Alex Stamos dismissed the findings with a public tweet.

Explaining The WhatsApp Security Flaw

The issues arise because of the extent to which a potential attacker could exploit this WhatsApp security flaw. They could block messages from admins or other members who may be trying to alert everyone well-nigh the new entrants, by caching messages and then selectively letting some through. A compromised WhatsApp server will also allow the hacker to decide which message gets sent to whom irrespective of the intended recipients.

The process gets a little tougher in groups with multiple admins, where, to make themselves seem like legit entrants into a grouping, the human being-in-the-middle needs to send different messages to each admin, making it seem like another one had invited them to the grouping. What'southward as alarming is the claim that even afterwards getting spotted as an uninvited guest, the hacker tin prevent their expulsion from the group.
