Flaw in WhatsApp and Signal exposes group chats to 'extremely difficult' hacks


Stamos added WhatsApp looked at the report carefully, but "following the researcher's plan would necessitate a change to the way WhatsApp provides a popular feature called group invite links - which are used millions of times per day". Upon pressing this button, it will skip all the messages where you have not been mentioned and highlight only the ones where you are mentioned. All group members will see that the attacker has joined.

This means that an attacker can add someone to a conversation and read all future messages sent in the chat (past messages are still hidden).

"When an administrator wishes to add a member to a group, it sends a message to the server identifying the group and the member to add".

A newly discovered security flaw in WhatsApp exposes the user's group chats to hackers.

DISH Adding Google Assistant Voice Commands
The reveal of Google's smart screens is fresh, so all of the details aren't in yet for each of the independent manufacturers. And this week we're announcing that over the coming year, more headphones are on the way from Jaybird, JBL, LG and Sony.

So the server can simply add a new member to a group with no interaction on the part of the administrator. "For example, it would be interesting to analyze the group chat implementations of other Signal-based messaging protocols, such as Google's Allo, Wire, and Facebook Messenger, or even non Signal-based protocols similarly to our investigation of Threema". The latest development suggests that the management is testing the "demote" feature, which will allow one group admin to reduce his fellow administrator to a normal participant.

WhatsApp said that the "group invitation bug" is a theoretical danger that's additionally minimized by the fact that users will receive a notification about a new user joining the group. Despite the sheer number of members in a group, someone is bound to notice an unexpected "guest" in their group. This would be possible without the need for the group administrator's permission, the researchers said. Open Whisper Systems declined to comment on the record to WIRED about the Ruhr researchers' findings. "If I hear there's end-to-end encryption for both groups and two-party communications, that means adding of new members should be protected against". The platform said it released a fix for the flaws. However, security researchers have recently found a flaw with the app that could leave those encrypted group chats vulnerable to eavesdroppers. WhatsApp has yet to take their advice.

Open Whisper Systems, the creators of Signal, told Wired that they are now redesigning how Signal handles group messaging, but did not share any more than that. Otherwise, they'd be wise to keep a vigilant eye out for any new entrants sliding into their private conversations.
